Carbachol, sold under the brand name Miostat among others, is a medication used to treat glaucoma or during eye surgery. Usually other agents such as pilocarpine or acetylcholine preferred. It is used as an eye drop or injected into the eye.

Common side effects include eye discomfort, headache, blurry vision, trouble seeing in low light, and red eyes. Other side effects may include allergic reactions, retinal detachment, diarrhea, low blood pressure, sweating, and arrhythmias. Safety in pregnancy is unclear. It is a cholinergic agonist that binds and activates acetylcholine receptors.

Carbachol was approved for medical use in the United States in 1972. It is on the World Health Organization's List of Essential Medicines as an alternative to pilocarpine. In the United States the solution for injection into the eye costs about 27 USD per dose as of 2021.
