If your night sweats started around the same time as a new prescription, there is a reason. And the supplements everyone is recommending may not be safe for you.
Here is a scenario that plays out more often than most people realize.
A woman in her late 40s starts an antidepressant — maybe for anxiety, maybe for depression that crept in during perimenopause, maybe because her doctor suggested it alongside other treatment. A few weeks later, she starts waking up soaked at 2 a.m. She assumes it is menopause. She starts researching. She finds black cohosh, St. John’s wort, ashwagandha. She reads that they are natural, that other women swear by them, that they have been used for centuries. She orders them on Amazon.
What nobody told her — what the wellness content she found almost certainly did not mention — is that several of those supplements can cause a serious, potentially dangerous interaction with the medication she is already taking.
This is not a niche concern. It affects a significant number of the women who are most actively looking for night sweat relief right now. And it deserves a clear, honest conversation.
First: why certain medications cause night sweats in the first place
Menopause gets most of the attention when night sweats come up, and for good reason — hormonal shifts are the most common cause. But medications are the second most common cause, and it is one that doctors do not always flag clearly when writing a prescription.
The mechanism varies depending on the drug, but in most cases it comes back to the same system: the hypothalamus, the part of the brain that regulates body temperature. When certain medications interfere with neurotransmitter activity — particularly serotonin, norepinephrine, and dopamine — they can essentially miscalibrate the body’s internal thermostat. The brain reads a temperature signal that is not really there and triggers a sweat response. At night, when you are still and there is nowhere for the heat to go, you wake up drenched.
The medications most commonly associated with this include:
Antidepressants — SSRIs (Prozac, Zoloft, Lexapro, Paxil, Celexa) and SNRIs (Effexor, Cymbalta, Pristiq) are among the most frequent offenders. Studies suggest that up to 20 percent of people taking these medications experience significant sweating as a side effect, with night sweats being particularly common.
Beta-blockers — Metoprolol, atenolol, propranolol and others prescribed for heart conditions, high blood pressure, and anxiety can cause night sweats.
Calcium channel blockers — Amlodipine, diltiazem, and similar heart and blood pressure medications are associated with flushing and sweating in a meaningful percentage of patients.
Tamoxifen and aromatase inhibitors — Women on these breast cancer treatments frequently experience severe hot flashes and night sweats.
Metformin — The most commonly prescribed diabetes medication is associated with sweating as a side effect, including night sweating in some patients.
Steroids and corticosteroids — Prednisone and similar medications can cause significant sweating, particularly as doses shift.
Amiodarone — This heart rhythm medication is associated with a range of side effects including sweating and temperature dysregulation.
Opioid pain medications — Both use and withdrawal from opioid medications can cause significant night sweats.
The trending herbal solutions — and what the Instagram posts don’t mention
Black cohosh has serotonergic properties — meaning it acts on serotonin receptors in the brain. When combined with medications that already affect serotonin, this can be a problem. In 2024, a case report documented a woman taking two antidepressants who began taking black cohosh for hot flashes and presented to the emergency department with serotonin toxicity and rhabdomyolysis. Black cohosh also appears to reduce the effectiveness of statins, amiodarone, glyburide, and fexofenadine.
St. John’s wort has the most extensive drug interaction profile of any supplement currently in common use. Taking it with SSRIs or SNRIs risks producing serotonin syndrome. It also reduces the effectiveness of digoxin, warfarin, oral contraceptives, cyclosporine, tacrolimus, certain HIV medications, alprazolam, and omeprazole.
Ashwagandha has become one of the most popular supplements across all wellness categories. In 2024, the Australian Therapeutic Goods Administration issued a formal safety advisory following reports of severe gastrointestinal symptoms and liver damage. It also has documented interactions with thyroid medications and immunosuppressants.
Ginseng has documented interactions with blood pressure medications, calcium channel blockers, certain statins, and warfarin — with unpredictable effects on anticoagulant activity.
Sage can lower blood sugar, and combined with metformin or other diabetes drugs, may push blood sugar too low. In larger doses it has been associated with rapid heartbeat and, in excessive amounts, seizures.
Kava has significant interactions with benzodiazepines and other central nervous system depressants, amplifying sedation in ways that can become dangerous. The FDA has previously issued warnings about kava and liver toxicity.
The real issue here
The woman most actively searching for night sweat relief right now is often the same woman whose night sweats are medication-induced — meaning she is already taking SSRIs, or heart medications, or tamoxifen, or metformin. She is the exact person for whom several of the most commonly recommended remedies carry the most significant risk.
Your pharmacist is often your best resource for catching interactions before they happen. Most pharmacy software flags herb-drug interactions the same way it flags drug-drug interactions, and a pharmacist will review your current medications against anything you are considering adding.
What actually works regardless of what you’re taking
There is one category of solution that has no drug interactions, no contraindications, and no consultation required: what you sleep in.
The sweating itself — wherever it comes from, whatever is causing it — is a moisture problem. If it ends up contained inside an absorbent garment, you do not wake up. This is what LunaDry was built for. The patent-pending absorbent system works the same way whether your night sweats are hormonal, medication-induced, or both. It does not interact with your SSRIs. It does not affect your heart medication. It does not require a consultation.
Some problems have medical solutions. This one also has a laundry solution. You do not have to choose between sleeping through the night and continuing the treatment that is keeping you well.
