Pilocarpine: uses, dosing, side effects & brands

How pilocarpine is dosed

From the FDA label for Salagen (application NDA020237). Other pilocarpine products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.

Regardless of the indication, the starting dose in patients with moderate hepatic impairment should be 5 mg twice daily, followed by adjustment based on therapeutic response and tolerability. Patients with mild hepatic insufficiency do not require dosage reductions. The use of pilocarpine in patients with severe hepatic insufficiency is not recommended. If needed, refer to the Hepatic Insufficiency subsection of the Precautions section of this label for definitions of mild, moderate and severe hepatic impairment. Head & Neck Cancer Patients: The recommended initial dose of Pilocarpine Hydrochloride Tablets is 5 mg taken three times a day. Dosage should be titrated according to therapeutic response and tolerance. The usual dosage range is up to 15-30 mg per day. (Not to exceed 10 mg per dose). Although early improvement may be realized, at least 12 weeks of uninterrupted therapy with Pilocarpine Hydrochloride Tablets may be necessary to assess whether a beneficial response will be achieved. The incidence of the most common adverse events increases with dose. The lowest dose that is tolerated and effective should be used for maintenance. Sjogren's Syndrome Patients: The recommended dose of Pilocarpine Hydrochloride Tablets is 5 mg taken four times a day. Efficacy was established by 6 weeks of use.
