WHY is this medicine prescribed?
Primidone is used alone or with other medications to control certain types of seizures. Primidone is in a class of medications called anticonvulsants. It works by decreasing abnormal electrical activity in the brain.
HOW should this medicine be used?
Primidone comes as a tablet to take by mouth. It is usually taken 3 to 4 times a day. Take primidone at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take primidone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of primidone and gradually increase your dose, not more often than once every 3 days. If you are taking another medication to treat your seizures and your doctor wants you to begin taking primidone instead, your doctor will gradually decrease your dose of the other medication and increase your dose of primidone over a period of at least 2 weeks.
Primidone may help control your condition but will not cure it. It may take several weeks or longer for you to feel the full benefit of this medication. Continue to take primidone even if you feel well. Do not stop taking primidone without talking to your doctor, even if you experience side effects such as unusual changes in behavior or mood. If you suddenly stop taking primidone, your seizures may become worse. Your doctor will probably decrease your dose gradually.
