Uses for pilocarpine
Pilocarpine tablets are used to treat dryness of the mouth and throat caused by a decrease in the amount of saliva that may occur after radiation treatment for cancer of the head and neck or in patients with Sjogren's syndrome. Pilocarpine may help you speak without having to sip liquids. It may also help with chewing, tasting, and swallowing. Pilocarpine may reduce your need for other oral comfort agents, such as hard candy, sugarless gum, or artificial saliva agents.
Pilocarpine may also be used to treat dryness of the eyes caused by Sjogren's syndrome
Pilocarpine is available only with your doctor's prescription.

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
