Valproate: what it treats and what you need to know
Valproate (valproic acid, sodium valproate) is a widely used medicine for epilepsy, bipolar disorder, and some migraine cases. You may see it prescribed when other drugs haven’t worked or when a doctor wants one medication that can help with both seizures and mood swings. It works by calming overactive brain activity, but because it affects multiple systems in the body, there are specific risks and checks you should know about before you start.
Key uses and how dosing looks
Doctors give valproate most often for generalized epilepsy (seizures that affect the whole brain) and for stabilizing mood in bipolar disorder. Doses vary a lot: many adults start around 500 mg a day and can be adjusted up to 1,500–2,000 mg daily depending on response and blood levels. Kids and older adults often get different schedules. Your prescriber should tailor the dose and may check blood levels (valproate serum concentration) to find the right balance between control and side effects.
Side effects, serious warnings and monitoring
Common short-term effects include drowsiness, dizziness, tremor, weight gain, nausea, and hair thinning. More serious issues to watch for are liver damage, pancreatitis, low platelets or other blood changes, and rare high ammonia levels causing confusion. Because of liver and blood risks, doctors usually order baseline and follow-up liver function tests (LFTs) and a full blood count (FBC).
One of the most important warnings: valproate can seriously harm a developing baby. Exposure in pregnancy is linked to birth defects and long-term developmental problems. If you're a woman of childbearing potential, discuss birth control, alternative medicines, and specialist review before starting valproate. Never stop or change the drug without talking to your doctor—sudden withdrawal can trigger seizures or mood relapse.
Drug interactions matter. Valproate raises levels of some drugs (for example, it can increase lamotrigine levels and the risk of rash). Certain antibiotics like carbapenems can crash valproate levels and cause loss of seizure control. Alcohol increases sedation and liver strain, so avoid heavy drinking while on valproate.
If you notice jaundice, severe stomach pain, unexplained bruising, sudden mood changes, or new cognitive problems, contact your prescriber or emergency care. For routine safety, your doctor may ask for periodic LFTs, blood counts, weight checks, and sometimes plasma valproate levels, especially when changing dose or adding other medicines.
Wondering about alternatives? Depending on your condition, options include lamotrigine, levetiracetam, carbamazepine, or mood stabilizers like lithium. Each has its own pros and cons, so a specialist can help match the best choice to your needs.
Final practical tips: keep a medication log (dose, side effects), don’t stop suddenly, get regular tests, and always mention valproate on any medical form or before surgery. Ask your prescriber about pregnancy planning and specialist review if you’re of childbearing age. If you want a short checklist to take to your next appointment, I can make one for you.
