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.
