Drug & supplement interaction

Cannabis + Rosuvastatin

Rosuvastatin brand names: Crestor, Ezallor.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Cannabis and Rosuvastatin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Cannabis and Rosuvastatin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Rosuvastatin and Cannabis in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Rosuvastatin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rosuvastatin is filed under 4 classifications — including hmg-coa reductase inhibitors ("statins"), hepatotoxic drugs, oral drugs. Cannabis has documented interactions with 18 drug classes — the most serious being warfarin (coumadin) (major), alcohol (ethanol) (moderate) and anesthesia (moderate) — and none of Rosuvastatin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Cannabis and Rosuvastatin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 10 of them are worth acting on rather than waiting out — marked below.

Reported for Cannabis but not commonly for Rosuvastatin: a stroke or mini-stroke, low blood pressure, an electrolyte imbalance and a heart attack.

Effects for Rosuvastatin come from the ADVERSE REACTIONS section of its FDA label; effects for Cannabis come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 223,851 voluntary FDA FAERS reports for Rosuvastatin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Special populations

Cannabis in Pregnancy & Breastfeeding

Pregnancy Unsafe

When used orally or inhaled. Constituents in cannabis pass through the placenta and can reduce fetal growth and increase the risk for preterm birth. Cannabis use during pregnancy is also associated with placental abruption, stillbirth, preterm delivery, fetal abnormalities, congenital birth defects of various organ systems, low birth weight, small for gestational age, increased need for neonatal intensive care, and childhood leukemia. Prenatal cannabis use has also been associated with long-term adverse developmental effects in the offspring, such as worsened cognition, increased risk for neurodevelopmental disorders such as autism spectrum disorder and attention deficit hyperactivity disorder, and increased risk for psychological issues during adolescence. Due to the observational nature of these studies, it is unclear if cannabis causes these adverse effects. Umbilical artery Doppler scans also show that cannabis use can increase placental vascular resistance. Cannabis use during pregnancy has been associated with increased risk of anemia and hypertension in the mother. The rate of negative fetal outcomes due to cannabis use during pregnancy may have been previously underestimated due to reliance on maternal self-reporting of use. Recent programs requiring maternal urine toxicology testing have increased awareness of maternal cannabis use and suggest that negative fetal outcomes occur more frequently than previously recorded.

Lactation Likely Unsafe

When used orally or inhaled. Delta-9-tetrahydrocannabinol (THC) is concentrated and excreted in breast milk for longer than 6 weeks after cessation of cannabis use. Prolonged cannabis use during lactation has been associated with delayed motor development. Observational research in mothers who successfully abstained from cannabis use for 6 weeks (confirmed by a negative THC urine screen) after smoking cannabis prenatally at least twice weekly, found that THC levels in breastmilk increased during the first 2 weeks of abstinence and then decreased but remained detectable at 6 weeks. For patients planning to breastfeed, recommend abstaining from cannabis use prenatally and during lactation. Recommendations to discard breastmilk until THC levels are undetectable are not practical, as this may take more than 6 weeks.

About Cannabis

What is Cannabis?

Cannabis
  • Chronic pain
  • Nausea and vomiting from chemotherapy
  • Muscle spasticity (e.g., multiple sclerosis)
  • Anxiety and stress
  • Sleep problems
  • Appetite stimulation

Cannabis contains many active compounds, mainly THC (which causes a 'high') and CBD (which does not). Some uses, such as chemotherapy-related nausea, certain seizure disorders, and muscle spasticity, have meaningful evidence, while many other popular uses are not well proven. It can cause real side effects and impairment, so talk to your doctor or pharmacist and follow your local laws before using it.

Cannabis sativa · Cannabaceae · Dried flowers (buds), leaves, and extracted resins/oils · Dried flower for smoking or vaporizing, edibles, oils and tinctures, capsules, topical creams, prescription products (e.g., dronabinol, nabilone, cannabidiol)

An interaction check asks whether these two react with each other — it does not ask whether Cannabis is a good idea for someone in your situation. Here is what our Cannabis record says about it on its own.

Cannabis: dosing

There is no single standard dose for cannabis. The right amount depends on the product, its strength, the THC and CBD content, how it is taken, and the person using it. Products can vary a lot in potency, which makes consistent dosing difficult.A common harm-reduction approach is to 'start low and go slow,' meaning begin with a small amount and wait to see how it affects you before taking more. This is especially important with edibles, which can take an hour or more to work.For prescription cannabis-based medicines, follow your doctor's instructions exactly.

About Rosuvastatin

What Is Rosuvastatin Used For?

Brand names: Crestor, Ezallor

Rosuvastatin tablets are used alongside diet changes to lower LDL-C ("bad" cholesterol), total cholesterol, and triglycerides (blood fats), and to raise HDL-C ("good" cholesterol) in adults with high cholesterol or mixed cholesterol problems. They are also used in adults with very high triglycerides, a condition called primary dysbetalipoproteinemia (Type III, a genetic fat-metabolism disorder), and to slow the buildup of plaque in arteries (atherosclerosis).

In people without established heart disease but with multiple risk factors, rosuvastatin tablets can reduce the risk of heart attack, stroke, and procedures to open blocked arteries. For children and teens aged 8 and older with heterozygous familial hypercholesterolemia (HeFH, an inherited high-cholesterol condition), the tablet form is used to lower LDL-C after diet alone has not worked. Crestor tablets are also approved to treat homozygous familial hypercholesterolemia (HoFH, a more severe inherited form) in adults and in children aged 7 and older.

Most-Reported Side Effects for Rosuvastatin

From FAERS, the FDA’s public side-effect reporting system (229,715 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Cannabis and Rosuvastatin Together: Common Questions

Is it safe to take Cannabis with Rosuvastatin?
We do not list a known interaction between Cannabis and Rosuvastatin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Cannabis and Rosuvastatin have any of the same side effects?
Yes — our sources link each of them separately to 10 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Cannabis and Rosuvastatin combination checked?
Interactions in our licensed database are recorded against drug classes. Rosuvastatin is filed under 4 classifications, and Cannabis has documented interactions with 18 drug classes — none of Rosuvastatin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Cannabis interact with any other medications?
Yes. Cannabis has 1,136 documented drug interactions in our database — Rosuvastatin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Rosuvastatin interact with any supplements?
Yes. Rosuvastatin has documented interactions with 63 supplements in our database — Cannabis is not one of them. The Rosuvastatin interaction page linked on this page lists every one, ranked by severity.
