Why is this medication prescribed?
Pilocarpine is used to treat dry mouth caused by radiotherapy in people with head and neck cancer and to treat dry mouth in people with Sjogren's syndrome (a condition that affects the immune system and causes dryness of certain parts of the body such as the eyes and mouth). Pilocarpine is in a class of medications called cholinergic agonists. It works by increasing the amount of saliva in the mouth.
How should this medicine be used?
Pilocarpine comes as a tablet to take by mouth. When pilocarpine is used to treat dry mouth caused by radiotherapy in people who have head and neck cancer, it is usually taken three times a day. When pilocarpine is used to treat dry mouth in people who have Sjogren's syndrome, it is usually taken four times a day. Take pilocarpine at around the same times 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 pilocarpine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on an average dose of pilocarpine and adjust your dose depending on how well your symptoms are controlled and the side effects you experience. Be sure to tell your doctor how you are feeling during your treatment with pilocarpine.
Pilocarpine will control your symptoms but will not cure your condition. Continue to take pilocarpine even if you feel well. Do not stop taking pilocarpine without talking to your doctor.
