Drug Induced Alopecia: Causes, Common Medications, and What You Can Do

When you start a new medication and notice your hair thinning or falling out, it’s not just in your head—it’s drug induced alopecia, hair loss triggered by prescription or over-the-counter drugs. Also known as medication-induced hair loss, this condition isn’t rare and often catches people off guard because it’s not always listed as a common side effect. Unlike genetic hair loss, which happens slowly over years, drug induced alopecia can show up within weeks after starting a new pill, injection, or cream. The good news? It’s usually temporary, and your hair often grows back once you stop the drug or switch to something else.

Not all hair loss from drugs works the same way. Some medications, like chemotherapy, powerful cancer treatments that attack fast-growing cells, including hair follicles, cause sudden, dramatic shedding. Others, like corticosteroids, anti-inflammatory drugs used for autoimmune conditions and allergies, might lead to slower thinning. Even common drugs like blood pressure pills, antidepressants, or birth control can trigger it in sensitive people. The key is recognizing the pattern: if your hair started falling out shortly after beginning a new medication, it’s worth talking to your doctor about whether the drug could be the cause.

Some drugs are more likely than others. For example, retinoids used for acne, certain anticoagulants, and even high-dose vitamin A supplements have been linked to hair loss. On the flip side, minoxidil, a topical treatment often used to regrow hair, is actually used to treat hair loss—but even it can cause temporary shedding in the first few weeks before regrowth begins. That’s why it’s so important to know whether your hair loss is from a drug that’s causing damage or one meant to fix it. You’re not alone if you’re worried—many people feel embarrassed or anxious about hair loss, but it’s a physical reaction, not a personal failure.
