Primidone for Tremor: How It Works and What Alternatives Exist

When it comes to controlling primidone, an anticonvulsant medication originally developed for epilepsy but now widely used for movement disorders. Also known as Mysoline, it works by calming overactive nerve signals in the brain that cause involuntary shaking. Many people with essential tremor—where hands shake during simple tasks like holding a cup or writing—find relief with primidone, even when beta-blockers like propranolol don’t help enough. It’s not a cure, but for thousands, it’s the difference between struggling to eat or being able to live normally.

Primidone doesn’t just target seizures; its effect on tremors is well-documented in clinical practice. Studies show it reduces tremor severity in about 70% of users, often more effectively than other drugs. But it’s not simple: side effects like dizziness, fatigue, or nausea can kick in early, especially when starting. That’s why doctors usually begin with a low dose and slowly increase it. It also takes weeks to reach full effect, so patience matters. People who take primidone long-term need regular blood tests to check liver function and drug levels—because too much can be dangerous, and too little won’t help. This isn’t a drug you pick off a shelf; it’s one you manage with your doctor.

It’s not the only option. propranolol, a beta-blocker commonly used for high blood pressure and heart conditions. Also known as Inderal, it’s often the first choice for tremor because it’s gentler and has fewer cognitive side effects. But if your tremor is severe or doesn’t respond to propranolol, primidone steps in. Other alternatives include topiramate, an antiseizure drug that also helps with tremor and migraines. Also known as Topamax, it’s used when primidone causes too many side effects, or gabapentin, a nerve-calming drug sometimes prescribed off-label for tremor. Also known as Neurontin, it’s less potent but easier to tolerate. Each has trade-offs: weight gain, brain fog, or tingling hands. That’s why knowing how primidone fits into the bigger picture matters.

What you’ll find below are real comparisons and insights from people who’ve used primidone for tremor—and others who’ve tried what comes after. You’ll see how it stacks up against other meds, what side effects actually feel like in daily life, and why some people switch while others stick with it for years. No fluff. Just what works, what doesn’t, and what your doctor might not have told you.
