HelloPharmacist Scorecard of Remifemin by Nature's Way
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
Remifemin contains one active ingredient: a black cohosh dry extract called RemiSure. Black cohosh is a plant long used for menopausal hot flashes and night sweats.
The product also contains inactive ingredients — lactose monohydrate, cellulose, potato starch, and magnesium stearate — which are fillers and binders to hold the tablet together.
Does it work?
Moderate evidence
The data we hold supports black cohosh as possibly effective for menopausal symptoms, which is what Remifemin is marketed for. For other uses — acne, sexual dysfunction, anxiety, and hot flashes from breast cancer — the evidence isn't established well enough to rate.
If you're considering this product for anything beyond menopausal symptoms, talk it over with your doctor or pharmacist first.
How safe is it?
Well-documented data
Black cohosh is generally well tolerated in typical short-term doses, with the most common side effects being breast tenderness, dizziness, stomach upset, headache, irritability, rash, and tiredness. Rare but serious concerns include liver damage (hepatotoxicity) and overgrowth of the uterine lining (endometrial hyperplasia), though the evidence for both is mixed.
There's one case report of seizures in someone using black cohosh with other supplements, and another of serotonin syndrome when added to antidepressants. Black cohosh is not recommended during pregnancy — there isn't enough safety data, and it may affect the uterus.
Safety while breastfeeding hasn't been established, so it's best avoided then too. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before using this product.
Meds to double-check
Moderate interaction found
Check with your pharmacist if you take serotonergic drugs like antidepressants or mood stabilizers (moderate concern for serotonin syndrome). Also double-check if you use medications broken down by a liver enzyme called CYP2D6, drugs that can damage the liver, estrogen therapy, or the chemotherapy drug cisplatin.
No interactions are documented for the OATP2B1 transport system beyond a minor inhibition, but the medication checker will flag any specific drugs you take.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Remifemin may help with menopausal hot flashes, but it has notable interactions with serotonergic drugs, liver-metabolized medications, and several other drug types. If you take any prescription medications — especially antidepressants — run them through the checker below before starting.
Pregnant or breastfeeding women should avoid it. Talk to your pharmacist if you have any liver concerns.

Remifemin by Nature's Way Drug Interactions
HelloPharmacist Interaction Report
Remifemin by Nature's Way contains black cohosh, which has documented interactions with a number of medications.
The most serious concern is with serotonergic drugs (antidepressants and similar medications) — black cohosh may increase the risk of serotonin syndrome, a potentially dangerous condition where too much serotonin builds up in your system.
Read the full breakdown — every affected drug type, severity by severity
Black cohosh also interacts with drugs metabolized by a liver enzyme called CYP2D6; the evidence is mixed, but some research suggests it might slow how your body clears these medications and raise their levels. There's a moderate concern with drugs that can damage the liver (hepatotoxic drugs) — combining them with black cohosh might increase that risk.
It may also alter how estrogen therapy works, reduce the effect of the chemotherapy drug cisplatin, and modestly inhibit a protein (OATP2B1) that moves certain drugs into your body.
Additionally, black cohosh has a minor interaction with drugs transported by OATP2B1 substrates.
Altogether, these interactions span 636 individual medications. Because the evidence is sometimes conflicting and the specifics depend on your exact drugs, use the medication checker on this page before you start.

For each ingredient in Remifemin with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
RemiSure dry extract
Atorvastatin (Lipitor)
Taking black cohosh with atorvastatin might increase the risk for elevated liver function tests.
In one case report, a patient taking atorvastatin (Lipitor) developed significantly elevated liver function enzymes after starting black cohosh 100 mg four times daily. Liver enzymes returned to normal when black cohosh was discontinued. It is unclear whether the elevated liver enzymes were due to black cohosh itself or an interaction between atorvastatin and black cohosh.
Cisplatin (Platinol-Aq)
Theoretically, black cohosh may reduce the clinical effects of cisplatin.
Animal research suggests that black cohosh might decrease the cytotoxic effect of cisplatin on breast cancer cells.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Some research suggests that black cohosh might inhibit CYP2D6, but there is conflicting evidence.
Some clinical research suggests that black cohosh might modestly inhibit CYP2D6 and increase levels of drugs metabolized by this enzyme. However, contradictory clinical research shows a specific black cohosh product (Remifemin, Enzymatic Therapy) 40 mg twice daily does not significantly inhibit metabolism of a CYP2D6 substrate in healthy study volunteers. Until more is known, use black cohosh cautiously in patients taking drugs metabolized by CYP2D6.
Estrogens
Theoretically, black cohosh may alter the effects of estrogen therapy.
Some research suggests that black cohosh has estrogenic effects. This may enhance or inhibit the effects of estrogen therapy.
Hepatotoxic Drugs
Theoretically, taking black cohosh with hepatotoxic drugs may increase the risk of liver damage.
There is concern that black cohosh might be linked to cases of liver failure and autoimmune hepatitis.
Serotonergic Drugs
Combining serotonergic drugs with black cohosh might cause additive serotonergic effects.
Black cohosh might increase the risk of serotonin syndrome when combined with other serotonergic drugs. Black cohosh acts as an agonist at several serotonin receptor subtypes and might interact with other serotonergic medications. In one case, a 55-year-old female who had been on stable treatment with sertraline 50 mg and duloxetine 60 mg daily developed serotonin syndrome after taking black cohosh extract 40 mg daily for 3 days.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Black cohosh may inhibit one form of OATP, OATP2B1, which could reduce the bioavailability and clinical effects of OATP2B1 substrates.
In vitro research shows that black cohosh modestly inhibits OATP2B1. OATPs are expressed in the small intestine and liver and are responsible for the uptake of drugs and other compounds into the body. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.
