CBD and medicines: are there any interactions or contraindications?
The properties of CBD, or cannabidiol, have been the focus of attention in the health community for many years. CBD, unlike THC, is completely legal in Switzerland. The plant can be used in a variety of forms, including CBD oil, flowers and topical creams. However, certain interactions, such as those between CBD and drugs, are of interest to health professionals, underlining the importance of consulting a specialist before any therapeutic use.
While these virtues are increasingly validated by science, one question remains for those on medication: is there a risk in consuming CBD alongside medication? Naturalpes reveals everything you need to know about CBD and drug interactions, as well as other contraindications to CBD use.
Do you need to be careful with medication when taking CBD?
To answer this question briefly: yes, you need to pay attention to the medications you take when using CBD. Interactions between CBD and medications, for example, can influence the effectiveness of treatments. Talking to your doctor about CBD is essential if you want to avoid any risks. The dangers of CBD are small, however, and possible drug interactions have yet to be fully investigated.
In any case, only a health professional can tell you if there is a drug interaction between your treatment and the use of CBD.
Cannabidiol and contraindications
Apart from interaction with certain medications, as is the case withGodl 20% CBD oil and drugs, there are few contraindications to the use of CBD, its side effects being rare and often less distressing than the symptoms it helps to alleviate. There are, however, a few.
You should be cautious about using CBD if :
- You are pregnant, as CBD is suspected of altering the properties of the placenta;
- Suffer from severe pollen allergy;
- You suffer from arterial or cardiac problems, as CBD can lower blood pressure.
CBD and cytochrome "P450" liver enzymes
The hepatic cytochrome "P450" enzymes are a group of enzymes responsible for the metabolism of most drugs in the body. These enzymes can activate or deactivate drugs. CBD has the ability to inhibit this enzyme.
This is also the case for grapefruit. This drug interaction, particularly between CBD and medication, is nevertheless negligible if the quantities used are moderate. A simple solution is to avoid taking CBD at the same time as medication.
CBD and antidepressants, anxiolytics and sleeping pills
Interactions between CBD and antidepressants, anxiolytics and sleeping pills are of particular concern, since these drugs have similar effects to cannabidiol. The same applies to CBD-drug combinations, which require particular vigilance due to their potential effects on blood fluidity.
At present, no studies appear to show any harmful interaction between these drugs and cannabidiol. Nevertheless, some users have reported problems of drowsiness and confusion.
CBD and thyroid hormones
Although we don't know exactly how, cannabinoids influence the concentration of thyroid hormones such as TSH and T4. No interaction with traditional treatments for thyroid problems has yet been detected.
CBD and corticoids (or steroidal anti-inflammatories)
Corticosteroids can be used to treat many types of chronic conditions and diseases, such as asthma, arthritis, lupus, ulcerative colitis, psoriasis, Crohn's disease and many others. It is thus a very widespread treatment. As with CBD and drugs, it is essential to assess possible interactions between CBD and corticosteroids before any joint use.
No known interactions with traditional treatments for thyroid problems have been detected to date. However, caution is advised.
CBD and antihistamines
A study has shown that CBD interacts with the enzymes metabolizing doxylamine, a first-generation antihistamine widely used around the world to treat allergy sufferers. This interaction would lead to cognitive impairment, drowsiness and breathing difficulties. Once again, further studies are needed to validate the interaction between these two substances.
CBD and anticoagulants
CBD's interactions with anticoagulants are not well understood. CBD is thought to interact with anticoagulants in a way that can lead to bleeding.
CBD is said to reduce platelet aggregation and prolong bleeding time. Studies are needed to prove this drug interaction. When taking CBD in combination with medication, talking to your doctor is an essential precaution.
CBD and painkillers
Interactions between CBD and painkillers do not appear to be dangerous in the present state of scientific knowledge. However, an American study suggests that the effects of these two substances may be additive, leading to drowsiness and cognitive impairment. Caution is therefore advised.
CBD and anti-hyperglycemics
People with diabetes take anti-hyperglycemic medication to control their blood sugar levels. Although the combined effect of CBD with certain drugs, as in the case of CBD and drugs, is still under study, risks such as lactic acidosis have been raised. As a precaution, we therefore recommend that you take care if you suffer from diabetes.
CBD: contraindications and drug interactions, what does it mean?
Numerous studies, corroborated by testimonials, seem to indicate that CBD use may interact with certain medications. Among them, CBD-drug interactions underscore the importance of remaining vigilant, especially as drug contraindications affect a significant proportion of the population.
However, this finding needs to be qualified. For almost all of these interactions, there are too few studies to draw reliable conclusions.
If there are serious interactions with common drugs, these will be brought to the attention of the medical community. For more reliable information, you can consult specialized sources such as naturalpes.ch, which keep a close eye on these subjects.
Just ask your doctor before using CBD. Feel free to share your experience in the comments section.
