Is CBD Safe to Take While Using Medications or Contraceptives?

One of the most common questions the Onyx & Rose team gets has to do with mixing our organic, all-natural product with medications and contraceptives. The risks associated with mixing pharmaceuticals and alcohol are well documented, so it’s natural that people would also have concerns regarding mixing CBD and prescription medications.

The short answer to this frequently asked question is that you should always check with your primary care physician before adding CBD to your daily routine.

If you’d like to take a deeper dive with us, read on!

The first important thing to note is that it’s possible for CBD to interact with other medications. While our product is organic and all natural, it can have an impact on metabolic rates, which in turn have an impact on the efficacy of certain medications. The good news is that this interaction often makes prescription medications more effective, leading to a lower dose of chemical medication when taken alongside CBD.

CBD and the P450 System

However, any drug that is metabolized by the liver will be affected by CBD, due to the cytochrome P450 enzyme system. This system is responsible for metabolizing potentially toxic compounds, and doctors use the amount of time it takes for various medications to be processed through the P450 system to determine safe and healthy dosages for patients. CBD can impact the P450 system, making it possible for certain drugs to spend more time in your system. Medications that may interact with CBD include antihistamines, NSAID pain relievers, beta blockers, antidepressants, antibiotics, and steroids. That’s why it’s especially important to consult with your physician before beginning a CBD regimen.

CBD and Birth Control

One of the most common medications that can interact with CBD is the birth control pill. Enzyme inhibitors such as CBD can potentially increase breakthrough bleeding and decrease estrogen-based contraceptive effectiveness, leading to an increased risk of unwanted pregnancy.

The active hormones in your method of birth control may also make a difference. Estrogen-containing contraceptives such as pills, patches, injections, and rings carry a higher risk of failure in the presence of CBD than non-estrogen forms. Progesterone-only alternatives may be a more reliable alternative for CBD users, and you’re a woman who’s concerned about becoming pregnant, you should consult with your doctor about your options. In the meantime, we advise using additional birth control methods such as condoms. Research in this area is still in progress, so we recommend that every woman use caution.

Talking With Your Doctor About CBD

If you don’t feel comfortable discussing your CBD regimen with your doctor, and you’re not prepared to begin the search for a new primary care physician at this time, then you can use what is commonly referred to as The Grapefruit Test to determine whether or not your medication will interact with CBD. CBD interacts with medications the same way grapefruit does, so if you’re unsure about mixing your medications with CBD, just ask your pharmacist or physician if you should avoid eating or drinking grapefruit while taking your medication. If the answer is yes, then your medication will interact with CBD and it will be important for you to have a more candid conversation with your doctor.

Endocannabinoid professionals recommend taking this precaution with every medication you may be prescribed, as many pharmacists and physicians are not highly educated on the endocannabinoid receptor system, and may not realize that patients may experience interactions. However, even though a lot of doctors aren’t up-to-date when it comes to CBD, they will still be the most important link to your health. They have the ability to monitor blood work and deserve your complete honesty when it comes to your CBD use. Only through transparency can you help destigmatize CBD and encourage the medical field to continue to research and study the endocannabinoid receptor system.

CBD and Birth Control: Does Hemp Oil Affect Contraceptive Pills?

CBD is the dominant compound in hemp-derived products that acts on the human endocannabinoid system when ingested. This system is intimately linked with major bodily functions, and that includes the reproductive system. CBD has been shown to affect female reproductive hormones such as estrogen, and thus it might affect birth control measures taken by women.

CBD also seems to affect the reproductive system overall and thus can cause the system not to function normally, thus potentially mimicking the effects of birth control.

CBD and Birth Control: How CBD Affects the CYP450 Enzyme System

Most of the medication we take is metabolized by the liver. CBD directly affects a liver enzyme called CP450. This enzyme is responsible for metabolizing about 60% of all the medication we take. This is the same reason why certain medications ask you to avoid grapefruit when using them.

CBD is more potent than grapefruit when it comes to disrupting this enzyme and thus makes it much harder for certain medications like birth control to do their job. Since the individual metabolism rate and various other physiological processes vary so much, it is important to recognize this fact before taking CBD in any form.

One vital point to keep in mind is that this interaction of CBD with the enzyme will cause the system to create a build-up of the various chemicals that are not getting processed at their normal speed. This can potentially create a problem by exaggerating the effects of the medication instead of undermining it because the active ingredients are accumulating in the body instead of getting used up.

Always talk to your doctor before taking CBD if you are on any active medication, including birth control.

CBD and Estrogen-based Birth Control Pills

This enzyme-blocking behavior makes it difficult for estrogen-based birth control to be effective. These include oral pills, patches, and rings. Progesterone-based birth control has been seen to not be affected in the same way and is thus presented as an alternative option for those who want to continue using CBD and birth control medication at the same time. Physical barrier methods like a condom are, of course, not going to be affected in any way by CBD. IUDs also remain effective contraceptive options when taking CBD.

Progesterone has been shown through research as a viable alternative to other hormone-based birth control measures; it also doesn’t produce any adverse sexual effects. CBD does not seem to change the body’s usage of external progesterone hormones, making it a viable alternative to estrogen and synthetic estrogen-based birth control.

How CBD Affects Estrogen In The Body

CBD is known to disrupt the estrogen production system in the body. Researchers who have measured this in various cannabis haven’t conducted much research on actual healthy individuals. The same researchers claim that the full effect of CBD on the estrogen production and distribution system is poorly understood.

The general observation is that CBD can interfere with estrogen-based birth control because of its interaction with the liver enzyme that helps metabolize external estrogen. At the same time, it seems to inhibit the production of estrogen in the body because it sometimes behaves like estrogen.

This simply underscores the fact that this part of the CBD interactions is poorly understood. The consensus seems to be that cannabis has a complex effect on the reproductive system because it changes so many essential reproductive functions of the body.

CBD and Hormones

As mentioned earlier, CBD has been known to interact with various hormones in several ways, such as the estrogen found in pills and the body. Each hormone reacts differently to CBD, and the final effect is very complex. The dosage of CBD also seems to affect the impact on various hormones. Overall, there is not enough research so far to produce simple answers. Instead, we only have a few functional pieces based on observation and data analysis, such as avoiding estrogen-based contraceptive pills.

Can CBD Be Used As Birth Control?

This seems to be a fairly common question when people discover the complex relationship between cannabinoids and the human reproductive system. The main takeaway here is that individual physiology has a significant impact on how this question is answered. So we can look at the various factors that affect these sexual and reproductive functions when CBD and other cannabinoids are taken.

Endocannabinoid System And The Reproductive System

The endocannabinoid system is present in various important female reproductive cells, and cannabinoids produced inside the body as well those ingested through something like CBD oil or extract, change the way these cells behave. This ends up affecting the way fertility-related events occur in women.

It has been found in areas of the brain responsible for controlling various aspects of the female reproductive system. So it seems to have an overall impact on fertility, reproduction, and other related hormonal functions.

How Cannabinoids Affect The Reproductive System

The effects of the various cannabinoids found in hemp include changes in how the body produces hormones and how the reproductive system works. It affects both male and female systems.

Both systems respond differently to CBD, as is to be expected in the case of causing changes to the reproductive system. It affects the main sex hormones in both instances, though, and seems to affect how the body changes based on these hormones.

THC has also been observed to specifically change the way the ovaries work in women, in this case also using the endocannabinoid system to create this change to sexual health.

It’s important to note that when these systems are changed in any way that strays from how they usually function, the changes can lead to the dysfunction of the entire system.

However, there are no direct studies investigating the effect of CBD on fertility, so doctors can’t recommend it as a means of birth control.

Related Therapeutic Possibilities

Another topic being studied now is how the endocannabinoid system interacts with certain forms of cancer. Various natural cannabinoids are being used in such studies, which involves investigating how cannabinoids work on the multiple mechanisms that control the functions of the ovary and uterus. Such research is providing new insights into how CBD affects sexual health, reproductive activity in women, other menstrual problems.

Cannabis Use And Its Impact On Pregnancy And ChildBirth

Researchers are still studying cannabis use during pregnancy. There has been some evidence to suggest that it may be connected to a slightly lower weight at the birth of the child. Otherwise, there seems to be no change in the other factors that affect human newborns.

Another study says the numbers related to the lower weight observed in mothers who used cannabis during pregnancy were too small to be considered. So they concluded that there was no connection between the two. They also said that there was no connection between cannabis use during pregnancy and health complications or deaths in newborns.

Impact of Cannabinoids On Male Sexual Health

There’s only a small number of studies that have analyzed the impact of cannabinoids on male sexual health. They mostly seem to contradict each other’s findings, thus not creating any consensus in the matter. What can be said confidently is that there appears to be some effect that cannabinoids can have on male sexual health, such as changes in semen production and increase testosterone levels.

Key Takeaways on CBD and Birth Control

The specific nature of CBDs interaction with birth control is a complex one. The only clear consensus seems to be that there is a strong possibility that estrogen-based contraceptive measures — pills, patches, rings, injections, etc. — will become ineffective when used with CBD products. The suggested alternative is using progesterone-based birth control pills, which continue to remain effective in the presence of CBD.

Since many CBD products also contain other cannabinoids that are part of the entourage effect, there is a possibility of a complex interaction with the reproductive system for both men and women.

Some researchers have suggested that there’s a risk that the reproductive system can be disrupted by the stimulation of the endocannabinoid system in a way that changes the way sperm production in men and egg release in women work. However, the research is still ongoing and will take some time to fully test out these initial results.

CBD and other related cannabinoids are very specific in the way they affect the body. This is the reason behind the confusion amongst researchers. Most conclude by echoing the need to investigate further.

CBD acts on many other hormones in the body, such as serotonin and dopamine, affecting our mood, eating patterns, circadian activity, and more. Combined with its impact on reproduction, it’s only within reason to assume that CBD has a cumulative effect on hormonal balance.

Will using cannabis make birth control less effective?

Unfortunately, there have been no scientific studies that completely answer the question of whether cannabis or its components (like CBD and THC) make birth control pills, patches, or rings less effective. This may be because “medical marijuana” has only been legalized on a state-by-state basis beginning in 1999 and as of yet not all states are on board. Additionally, cannabis products containing THC are illegal federally and in most states. Regulations around CBD, the non-psychoactive component of cannabis, vary by state.

In the limited research that has been done, CBD (or cannabidiol) did not appear to stimulate the estrogen receptors on cells, nor block the effects of estrogen on those receptors, which indicates that it’s unlikely to interfere with how estrogen in birth control affects the body. Moreover, CBD slows down enzymes that break down the hormones in birth control. This argues that, if anything, the birth control hormones may be in the body longer and at higher concentrations. Putting all this together, we can definitely say that CBD will not make birth control less effective.

Anecdotally, I haven’t heard or read about women experiencing unplanned pregnancies while using cannabis products and taking hormonal birth control.
