Saliva-Boosting Pills for Dry Mouth: Pilocarpine and Cevimeline Label Checks
Breath & MouthArticleWhen sprays, gels and sips of water aren't enough, two prescription pills can help the salivary glands make more saliva in Sjögren's disease, and one is also approved after head and neck radiation. Sweating is the most common side effect, and night vision can blur.

Dry mouth makes it hard to talk, swallow and sleep, and it raises your risk of cavities. Medicines are a common cause, but Sjögren’s disease, an autoimmune condition that mostly affects women, and radiation for head and neck cancer can damage the salivary glands themselves. Two prescription pills help those glands make more saliva.
The two options
| Pilocarpine | Cevimeline | |
|---|---|---|
| Approved for | Dry mouth in Sjögren’s, and after head and neck radiation1 | Dry mouth in Sjögren’s2 |
| Usual dose | 5 mg four times a day for Sjögren’s1 | 30 mg three times a day2 |
| Excess sweating in trials | Common, and more frequent at higher doses1 | About 19%, compared with 2% on placebo2 |
For Sjögren’s, pilocarpine’s benefit was shown by 6 weeks.1 After radiation, the label says at least 12 weeks of steady use may be needed to judge whether it’s working.1
Who shouldn’t take them
Both labels say not to use them with:12
- uncontrolled asthma
- narrow-angle glaucoma or certain eye inflammation
- a known allergy to the medicine
Both call for caution and close supervision with significant heart disease or lung disease such as COPD.12 Cevimeline also calls for caution with a history of kidney stones or gallstones.2
Side effects to know
- Sweating is the most common. If you sweat a lot and can’t drink enough, you can become dehydrated.12
- Blurred vision, especially at night, can affect driving.12
- Nausea, runny nose, diarrhea, flushing and needing to urinate more often are also reported.12
- Pilocarpine needs caution with beta blockers.1
In cevimeline’s U.S. trials, about 15% of people stopped because of side effects.2
Other steps that still matter
Ask whether any of your medicines are drying your mouth. Our guides to dry mouth at the dentist, saliva products, xylitol lozenges and prescription fluoride toothpaste cover other protections.
Questions to ask
- Is my dry mouth from my glands or from my medicines?
- Is either pill safe with my heart, lungs and eyes?
- How long should I try it before deciding?
- What should I do about sweating in hot weather?
Try: “My mouth is so dry I wake up at night to sip water. I have Sjögren’s. Would a saliva-boosting pill help me, given my blood pressure medicine?”
