Lasmiditan Risks: What You Need to Know Before Taking It
When you take lasmiditan, a prescription migraine medication designed to relieve acute headaches without constricting blood vessels. It's not like older migraine drugs—it doesn’t narrow arteries, which makes it safer for people with heart issues. But that doesn’t mean it’s harmless. Also known as Reyvow, it works on serotonin receptors in the brain, and that’s where the real risks begin.
Lasmiditan risks aren’t just about dizziness or feeling tired. The biggest danger is serotonin syndrome, a life-threatening reaction caused by too much serotonin in the brain. This can happen if you take lasmiditan with other serotonin-boosting drugs like SSRIs, SNRIs, or even certain herbal supplements. Symptoms? Confusion, rapid heartbeat, high fever, muscle stiffness. If you’ve ever been on antidepressants, you need to know this. It’s not a "maybe"—it’s a hard stop unless your doctor specifically says it’s safe. Another major concern is impaired driving ability, a side effect so strong the FDA requires a warning that you must not drive or operate heavy machinery for at least 8 hours after taking it. Unlike other migraine pills, you can’t just pop one and keep going. Your brain literally slows down. And if you’re over 65 or have liver problems, your body clears it slower—meaning side effects hit harder and last longer.
There’s also the issue of drug interactions, especially with other central nervous system depressants like alcohol, benzodiazepines, or opioid painkillers. Mixing these can lead to extreme drowsiness, trouble breathing, or even unconsciousness. Even over-the-counter sleep aids can be risky. And don’t assume that because it’s a newer drug, it’s safer than older ones—it just has different dangers. If you’ve had a stroke, heart attack, or uncontrolled high blood pressure, lasmiditan might not be right for you at all. Your doctor should check your full medication list before prescribing it.
