What is Pilocarpine?
Simply put, Pilocarpine is a medicine that helps increase saliva production in your mouth. Your body has glands called salivary glands that make spit to keep your mouth moist.
Sometimes these glands stop working well. Pilocarpine steps in to wake those glands up and help them make more saliva.
When this happens, the dry feeling in your mouth starts to fade away. This makes it much easier for you to swallow food and speak clearly again.
Sometimes, doctors use a different form of this medicine, such as eye drops, to treat dry eyes. But in this guide, we are focusing on the pills you swallow by mouth.

This is a very important step. Before your doctor prescribes Pilocarpine, they need to know your complete medical history to keep you safe.
