Cold Medicine and CBD Oil: Potential Side Effects and Benefits

Cold Medicine and CBD Oil: Potential Side Effects and Benefits

Depending on the type of cold medicine you’re using, adding CBD oil to the mix could cause you to feel more drowsy than normal.

If you’re dealing with a bad cold you may find yourself reaching for something in the medicine cabinet, but before you do, you may want to find out how CBD oil can help.

Cannabidiol (CBD) is one of 100+ cannabinoids found in the cannabis plant, and unlike the cannabinoid, tetrahydrocannabinol (THC), it does not produce the mind-altering “high” associated with marijuana consumption.

CBD oil can, however, reduce inflammation and boost the immune system, making it an ideal supplement when you’re feeling under the weather.

If you want to combine CBD oil with your cold medication, or want to better understand how CBD oil can help relieve the symptoms of your cold, here’s what you need to know.

Interactions Between CBD and Cold Medicine

There are a few cold medications that can react negatively with CBD oil.

The biggest risk comes from combining two compounds that share a comparable function. While the relaxing properties of CBD oil alone may be mild, when you add another product that produces a similar sedating effect, the results can be amplified to an undesirable degree.

Cough medicines in particular often contain ingredients that promote sleep. As CBD oil can also have a calming effect, the combined outcome can be sedation that’s stronger than you may have prepared for. While this may not be an issue at night time, it is worth noting if you are taking your CBD oil and cold medicine during the day or any other time you need to be awake and alert (e.g. while driving).

Additionally, CBD oil slows down the cytochrome P450 (CP450) system, a collection of enzymes in your liver that process many different medications. The CP450 system breaks certain compounds, including some ingredients found in common cold medicines, down into smaller pieces, allowing the body to more easily make use of them. When CBD oil slows this system, medications may remain in the body for longer periods, making their side effects more likely to occur.

With that in mind, there are a few ingredients found in cold medications you should look for if you’re also taking CBD oil. For your reference, here’s a table outlining the most common active ingredients in cold medicine and the potential outcome when taken with CBD oil.

Ingredient Possible interaction when combined with CBD oil
Pheniramine – Found in flu and combination cold medicines (e.g. Theraflu and Scot-Tussin products) May increase the risk of side effects and potential for drowsiness when used with CBD oil
Phenylephrine – Found in decongestants (e.g. Neo-Synephrine; Sudafed PE Congestion; Vazculep) Increased risk of high resting heart rate when used with CBD oil
Pseudoephedrine – Found in decongestants (e.g. Sudafed Congestion; SudoGest; Sudafed 12-Hour; Entex) Increases risk of serotonin syndrome when used with CBD oil
Naproxen – Found in anti-inflammatory medications (e.g. Aleve and Naprosyn) May make CBD oil less effective
Acetaminophen – Found in pain relievers (e.g. Tylenol) No known interactions
Chlorpheniramine – Found in a variety of antihistamines (allergy reducers) May increase the risk of side effects and potential for drowsiness when used with CBD oil
Doxylamine – Found in some anti-anxiety and sedation medications (e.g. SleepAid; Unisom Sleep Tabs; Equate Sleep Aid) May increase the drowsy or calming effects of CBD oil
Guaifenesin – Found in expectorants (e.g. Mucinex; Robitussin Chest Congestion; Robafen; Tussin) No known interactions

If you begin to notice unwanted effects after using CBD oil with any cold medication, do not continue with the combination and speak to your doctor.

CBD Oil for Treating Cold Symptoms

The next time you’re sick, before reaching for your cold medication, consider using CBD oil. Not only is CBD oil widely well-tolerated with a good safety profile, it can have positive effects on many of the most common cold symptoms. In addition, because of cannabidiol’s antibacterial properties, CBD oil can keep a cold at bay by helping your immune system fight the intruder at the source.

CBD for Congestion

One of the most annoying cold symptoms is nasal congestion. While research is not yet conclusive, there is evidence to suggest that CBD oil may be useful in clearing blocked sinuses. Targeting the inflammation, CBD can calm the membranes that line your nasal passages, decreasing congestion and opening up those airways.

CBD for Fevers

There are many reasons you might develop a fever when you’re sick. It may be caused by your body fighting a viral infection, like the common cold, or a sign of inflammation taking place within. If the fever is brought on by a virus, early research suggests cannabinoids could play a role in inhibiting its progression.

Alternatively, if the fever is part of a larger inflammatory reaction, the use of CBD oil can trigger an anti-inflammatory response through its action in your body’s endocannabinoid system.

CBD for coughs and sneezes

Research has shown that the properties of CBD oil include not only anti-inflammatory effects, but muscle-relaxant qualities too. This is particularly of interest if you’re suffering from a persistent cough, as CBD oil may reduce the inflamed airway and relax the muscles to reduce coughing.

CBD oil may also block histamines, the compounds responsible for inducing bouts of coughing and sneezing. While CBD oil hasn’t been proven to be as effective as the antihistamine ingredients in cold medication, it does offer the potential for a more natural treatment.

How to Safely Use CBD Oil and Cold Medicine Together

For starters, talk to your doctor. Although CBD oil is largely side effect-free and well-tolerated, there could be factors in your personal health history that warrant extra caution before using CBD.

Furthermore, if you wish to safely combine CBD oil and cold medication, avoid ingredients which may cause negative interactions (see the table in ‘Interactions Between CBD and Cold Medicine’ above). Also, keep in mind any cold or flu medicines advertised as helping with sleep may have amplified effects when used with CBD oil.

It is suggested that you either take the combination before bed or spread their use over the day; for example take CBD oil in the morning and cold medicine at night. Alternatively, you can opt to combine non-drowsy cold medicine with your CBD oil. Just be aware of whether the medications contain any ingredients metabolized by your body’s cytochrome P-450 pathway to best avoid unpleasant side effects.

Safest CBD Oils to Take with Cold Medication

There is an incredible variety of cannabidiol products available online and in-store, so how do you find the safest CBD oil?

Narrow down the options by first deciding the method you’d like to use to take your CBD oil. If you are suffering from a cold, it’s likely that your respiratory system isn’t operating at full capacity. For that reason, it’s best to ingest your CBD instead of inhaling it (i.e. via CBD vape or flower). Using CBD oil drops, tinctures, edibles, or capsules will cause the least disruption to your body as it is trying to heal.

When you’ve made the decision on how you’ll be taking your CBD oil, ensure you choose the safest product by doing your research into quality CBD brands.

The best companies use sustainably sourced hemp which has been organically grown without the use of herbicides, pesticides, or chemical additives. For peace of mind, check the product’s Certificate of Analysis (COA), which will clarify whether the CBD product contains any heavy metals or toxins. The COA will also indicate how much CBD and THC is in your product, amongst other cannabinoids and terpenes, so you’ll know if the dosage is accurate. Ideally, the COA should be published by a third-party laboratory, ensuring it is not subject to bias.

Remember, when it comes to your health, it’s worth taking the time to find the best quality CBD products.

If you’ve come down with a cold, there are a few side effects and benefits you should know about before combining your cold medication with CBD oil.

CBD Oil Side Effects Nobody Told You About

CBD oil — that magnificent, powerful phrase/product/cure that we have heard so much about. Everywhere you turn, there are praise and glory about its impact. However, rarely does one hear anything about CBD oil side effects, even though they are extremely important.

The “bad boy” THC is to be partially blamed for this. The public has been focused on its effects for so long, even trying to ban cannabis completely due to this psychoactive ingredient. Getting “high” used to be seen as the ultimate crime. At the same time, the medical benefits of cannabis were hard to deny. That said, when CBD was discovered, people were inclined to believe CBD effects are what makes cannabis such a powerful healer.

However, nothing is perfect, and neither is CBD. Contained in hemp oil or not, with or without some THC content, CBD oil comes with its fair share of downsides.

Let’s first take a quick look at what CBD is, and then you’ll find out everything there is to know about its detrimental effects.

CBD Basics

What Is CBD?

CBD (cannabidiol) is just one of many cannabinoids in the cannabis plant. CBD structure remains absolutely the same whether we’re talking about CBD from hemp (Cannabis Sativa) or the ‘’regular cannabis” (Cannabis Indica).

There are over 80 cannabinoids within cannabis. These natural substances have the ability to bind to our own endocannabinoid system. This is the reason why CBD is so efficient in the first place — our body recognizes it as a familiar substance. Luckily for us, CBD research suggests new incredible health benefits every day.

What Is CBD Oil?

To better understand CBD oil side effects, let’s first explain what the oil actually represents.

There are two types of CBD oil:

  • Pure CBD oil
  • Full-spectrum CBD oil.

The first one is guaranteed to have nothing else but CBD and carrier oil (olive, avocado, hemp seed oil, coconut oil, etc.). The latter comprises of CBD, THC, and all the other cannabinoids you can find in a cannabis plant. Terpenes come into the picture as well.

CBD oil can be taken in various ways — as the oil itself and as a CBD oil-infused product (CBD gummies, creams, lotions, patches, pills, and so on).

Side Effects of CBD Oil

Similar to any medicine, CBD oil comes with a (long) list of warnings. And just like it is the case with any other, the side effect may or may not exhibit themselves. Regardless of the reason, the fact remains that some people will endure the negative effects.

One of the biggest reasons for this is the fact that we are all different and that our bodies react individually to a stimulant. In addition to this, there are some things we can influence so as to avoid the side effects of CBD and get the maximum of its good sides.

Sleepiness

Whereas it is usually THC that is praised for a cannabis treatment for insomnia, CBD can make you drowsy as well. This is usually the case if you take a higher CBD dose than recommended. On the other hand, if you wish to avoid these CBD negative side effects, just take a smaller dose.

Nausea

CBD is not cut out for a sensitive stomach or palate.

If you take CBD in the form of oil drops, you could feel sick. This is especially true if you take it on an empty stomach. The general rule of thumb applies here as well — take your medicine half an hour or an hour after a meal. Drink plenty of water afterward.

Due to its application, CBD cream side effects will include some other states, such as tiredness, but hardly ever nausea.

Appetite Boost or Loss

Depending on what you’re trying to achieve, this could be great for you. CBD oil products are very much praised for increasing appetite, particularly in cancer patients. In addition, CBD oil for anxiety and reduced anxiety levels usually encourage people to eat more. The appetite-boosting quality is mostly connected with full-spectrum CBD oil.

Dry Mouth

One of the most common CBD oil side effects is dry mouth. Basically, it is the feeling as if someone filled your mouth with cotton balls. It usually occurs if you’re using oil drops. The scientific experiment behind it suggests that CBD inhibits the endocannabinoid receptors in our brain, which are responsible for saliva production.

Luckily, dry mouth is only temporary and easily solved — just take a big glass of water after consuming CBD oil.

Diarrhea

The side effects of CBD oil in dogs and humans may appear in this form. Here are two reasons why you may be experiencing this symptom:

  • As with any other medication, your body needs some time to adjust to it.
  • Since CBD oil alters your appetite, you may have changed your regular eating habits. Your gut gets revolted against the smaller or bigger food intake.

After one or two weeks, the symptoms should stop. Your body will adjust to CBD oil benefits and side effects and the new eating pattern. In case you are already suffering from diabetes or similar appetite/weight loss condition, be very careful about maintaining your goal weight.

Vivid Dreams

On the one hand, this oil will help you fall asleep faster. On the other hand, you may experience very realistic dreams during the first couple of nights. Even nightmares.

What happens is that CBD allows you to enter a deep sleep stage called N3, delta sleep, or slow-wave sleep. Luckily, you should be free of bad dreams after two days or as much as it takes your brain to adjust to the new substance.

CBD Oil Side Effects on Kidneys

There are some opposite opinions on this one. According to one study, cannabis is beneficial for patients with advanced chronic kidney disease (CKD). It helps them regulate the pain and exhibits no side issues.

In another research, though, it was found that cannabis has an adverse effect, especially if it’s consumed via smoking. Patients were advised against medical marijuana, and CBD oil possibly could have the same effect.

What are the side effects of CBD for healthy people? Apparently, none. Those who did not suffer from kidney disease did not show any reduction in kidney functions while using cannabis.

Dizziness

Dizziness due to CBD oil normally occurs if one takes a higher dose than they should. The easiest way for this to happen is during vaping. It takes some skill to master it because it isn’t the same as smoking a joint. Usually, people smoke concentrates rich in CBD, THC, and terpenes, so the “high” hits them unexpectedly.

To avoid side effects of vaping CBD, be moderate and careful about how you get the CBD vape oil.

Dizziness could be caused by low blood pressure too.

Parkinson’s Disease

CBD oil is actually recommended for treating Parkinson’s. Evidence of abuse is scarce.

Usually, patients are advised against using CBD if it interacts with some other medications. Mood changes, diarrhea, and tiredness may occur in these cases.

More serious side effects such as worsening the disease symptoms occur with too high dosage.

Grapefruit Warning

Grapefruit and CBD pills side effects can be identical. Grapefruit and similar fruit contain certain substances that interact with CYP450 enzymes in particular. In short, it prevents them from doing their job of dealing with the drugs we take. This way, too much medicine goes straight to the liver and isn’t processed before entering the bloodstream. Eventually, you end up with more drug that you are entitled to.

CBD behaves in a similar way. What is worse, it interferes with more enzymes (CYP3A4 and CYP2D6) and increases the drug level even more. Quitting CBD oil usage doesn’t let your body use the drug normally until a few days have passed.

In this respect, side effects of CBD oil will show if a person is taking some antidepressants, antihistamines, benzodiazepines, and statins.

To prevent the triggers in this case, be wary of the grapefruit warning on medications. Otherwise, CBD will turn the low dose of your medicine into a high dose.

CBD Oil Side Effects on Liver

This topic is pretty much intriguing, as it recently made the headlines.

Most articles that are against CBD oil usage rely on a mice study. Having been exposed to high CBD doses, they developed hepatotoxicity. However, what is usually omitted from catchy headlines is the fact that CBD was given in high doses. For example, the doses equaled what would be three and ten times bigger doses than the recommended one for Epidiolex.

Essentially, Epidiolex is pure CBD oil. It does come with a label warning about CBD hemp oil side effects, saying it should be used with caution if one is taking liver meds. Still, taking a dosage three times bigger is worrying no matter which medicine we are talking about.

Interestingly, CBD oil for liver cancer has shown some great effects, as there was even an example of a man coughing up dead cancer cells (!) after the CBD oil treatment.

To sum up, side effects are possible, but if your liver is healthy, they will occur only with extremely high doses.

Headaches and Migraines

When buying CBD oil of some kind, these CBD oil side effects may be listed on the label. In reality, the chances of CBD provoking headache are very low.

According to one study, CBD does not cause headaches or migraines. On the contrary, it is recommended as a cure.

The cause of headaches may have more to do with any substances or solvents added to the oil. Not all CBD oil for pain brands are reliable, so sometimes, a simple change of CBD brand will end the pain.

Reverse Tolerance

With CBD, you never know. Your body may develop tolerance to CBD effects after some time. This usually happens if your CBD oil contains THC. In contrast, you may be in for a surprise. CBD is also known to cause reverse tolerance. This means you will need a smaller dose after using CBD for a long time.

To be safe, monitor your doses and reactions.

Low Blood Pressure

The reason for lowering blood pressure could be that CBD may act as a blood thinner. If you’re already on blood-thinning meds, these side effects of CBD oil are very dangerous. For instance, even though CBD helps post-surgical pain and recovery, you shouldn’t be taking it one week before the operation.

CBD dilates blood vessels and is an excellent aid in preventing thrombosis or the formation of blood clots. But if you’re already using blood thinners, always consult your doctor.

Allergy to CBD

What are the side effects of CBD oil? Some of them are allergy symptoms.

An allergy to cannabis is a real thing. It manifests similarly to any other pollen allergy — runny nose, sneezing, rash, or itchy skin. The allergy may be provoked by airborne allergens, handling the plant (people working in the industry are especially at risk), or by eating some of the delicious edibles. What is more, you may have a mild allergy to cannabis, but it could make other allergies stronger, particularly food allergies.

If you are taking CBD oil for the first time, beware of these side effects of CBD oil in humans — dry cough, itchy eyes, sore throat, dry skin, blisters, hives, or watery eyes. Should you experience any of these, you may be having an allergic reaction to CBD oil.

CBD Oil Interactions With Other Drugs

Admittedly, the list is quite lengthy. We have already mentioned some precautions when we discussed blood thinners and liver meds. Here is what to pay special attention to if you’re using CBD.

It will interact with the following, so we strongly advise you against using CBD with:

  • Clobazam (Onfi), and
  • Valproate.

CBD may interact with:

  • Zonisamide
  • Topiramate (Topamax)
  • Sedative medications (CNS depressants), such as Nembutal, Luminal, Seconal, Duragesic, Sublimaze, morphine, Diprivan, Pentothal, and others.
  • Rufinamide (Banzel).

Side effects of CBD hemp oil can be shown if you use:

  • Medications that increase/decrease the breakdown of other medications by the liver:

Tagamet, Luvox, Prilosec, Ticlid, Topamax, Tegretol, Dilantin, Mycobutin, etc.

  • Medications that decrease the breakdown of other medications in the liver, such as:

Cordarone, Fortovase, Invirase, E-Mycin, Erythrocin, Cardizem, etc.

  • Medications changed by the liver:

Endometrin, Prometrium, Adalat CC, Procardia XL, Sandimmune, Xanax, Norvasc, Biaxin, Sandimmune, erythromycin, Mevacor, Nizoral, Sporanox, Allegra, Halcion, Calan, Isoptin and many others.

  • Eslicarbazepine (Aptiom).

Does CBD Oil Have Side Effects in Pregnancy?

As a matter of fact, nobody knows. The American College of Obstetricians and Gynecologists (ACOG) advises pregnant women against using cannabis in all its forms, CBD oil included.

So far, research on CBD oil dangers during pregnancy hasn’t been conducted. The existing studies all rely on cases when mothers-to-be were regular cannabis consumers. Smoking weed or eating cannabis during pregnancy is dangerous for the baby and may even cause stillbirth.

However, there is no evidence whatsoever that the use of CBD oil could cause the same consequences.

More Dangers of Using CBD Oil

This section has nothing to do with how your body processes CBD, but rather with side effects of CBD oil. It deals with whether or not you got what you paid for. Namely, CBD oil regulations are far from picture-perfect. Unless you are buying from a reliable source, you may experience some hardships.

Here are a couple of reasons which may repel you from consuming cannabidiol.

  • FDA — believe it or not, CBD oil is not FDA regulated. It is isn’t even listed as an FDA-approved dietary supplement. How is this possible? Most probably, the main reason for mistrust would be that cannabis is still listed as a Schedule 1 drug. Hence, it’s a bit challenging to do the paperwork for something similar to heroin (which belongs to Schedule 1 too).

CBD oil reviews without an official FDA stamp of approval may not be reliable at all. Not being FDA “blessed” gives enough chance to manufacturers to advertise the products as they wish and alter CBD oil’s content without harsh penalties.

  • Traces of THC — you could end up with more than you’ve bargained for. Some pure CBD oils may contain THC (even though they mustn’t). This is especially dangerous if a child is recommended pure CBD oil as THC is detrimental to young neural paths. In addition, that can make you positive on a drug test as THC lingers in your system for a long time. Not all drug tests can discover THC, though.
  • Harmful substances — sometimes, you may think you’re dealing with the negative side effects of CBD oil, but another substance is to blame. There are lots of CBD oil-infused products out there. Even if CBD oil is of perfect quality, it can be mixed with not-so-good ingredients.

The latest example comes in the form of vaping respiratory disease. It has already taken seven lives. The jury is still out, but the CBD vape oil side effects could be attributed to a harmful substance added to vaping liquid.

In addition, less reputable companies may treat the land and plants with poisonous pesticides to have a higher yield.

  • Insufficient amount of CBD — some CBD oils can have less CBD than it says on the label and more of carrier oil. Consequently, your condition requiring CBD won’t improve. Even worse, if you change the product but keep the dosage, you could overdose on CBD and experience all the negative side effects of CBD.
  • Type of use — interaction with other medications and similar side effects depend a lot on how exactly you are taking your recommended dose. CBD lotions or creams shouldn’t provide you with high doses of CBD. As for CBD edibles, CBD gummies side effects are felt less compared to taking CBD via vaping, smoking, or sublingually.

Conclusion

So what can we say about CBD oil in the end? First of all, don’t get carried away by the worldwide frenzy.

  • Always consult your doctor before taking any form of CBD oil.
  • Buy the oil only from reputable suppliers. These should always state their products were tested by independent laboratories, and their findings should be available. The same applies if you decide to make your own CBD oil. Always use the best ingredients.
  • To avoid CBD oil side effects, you are to stick to the recommended dose. The majority of issues are connected with overdosing.
  • Bear in mind how you take CBD oil — via CBD pills, oil, tincture, cream, edibles, or patches.

Finally, monitor your body and the results you get. CBD oil benefits are just too good to be missed. Hopefully, you are fully eligible to enjoy its advantages without any dangers to your health.

CBD oil benefits are all over the internet, but what about CBD oil side effects? Their list is quite extensive, too. Cannabidiol is not for everyone to use.
