Hot Flashes from Drugs: Causes, Common Medications, and What to Do

When you get sudden, intense heat waves—sweating, flushing, heart racing—it’s easy to assume it’s menopause. But hot flashes from drugs, sudden bursts of body heat triggered by medications rather than hormonal shifts. Also known as drug-induced hot flashes, they can happen to anyone taking certain prescriptions or even over-the-counter drugs. These aren’t just annoying—they can mess with sleep, mood, and daily life. And the truth is, you might not even realize your medicine is the cause.

Many common drugs pull this off. hormone therapy, used for breast cancer or menopause symptoms, often causes hot flashes as a side effect because it changes estrogen levels. Tamoxifen, for example, blocks estrogen in some tissues, tricking your body into thinking it’s in menopause—even if you’re not. antidepressants, especially SSRIs and SNRIs like fluoxetine or venlafaxine, are another big one. They affect serotonin, which controls body temperature, and that can throw your internal thermostat off. Even osteoporosis drugs, like denosumab or bisphosphonates, can trigger them in some people. And don’t forget about chemotherapy, which can damage ovaries or alter hormone balance. If you started a new med and the heat waves came right after, that’s not a coincidence.

It’s not just about stopping the drug, either. Sometimes you can’t stop it—your health depends on it. But there are ways to manage it. Simple stuff like wearing layers, keeping your room cool, avoiding spicy food or alcohol, and practicing deep breathing can help. Some people find relief with gabapentin or clonidine, both used off-label for this. And if you’re on tamoxifen or another cancer drug, your doctor might adjust your dose or add a non-hormonal option to reduce the flushes. The key is to track when they happen, what you’re taking, and how bad they get. Bring that info to your next appointment.
