Papaverine is a medication primarily used to treat arterial spasm and erectile dysfunction (ED). It is not a first line agent for ED. Other uses have include painful periods and gastrointestinal spasms. It is given by mouth or by injection. Onset is relatively rapid and lasts for hours.

Common side effects include nausea, constipation, headache, abdominal pain, flushing, low blood pressure, and priapism. Other side effects may include respiratory arrest, liver problems, abuse, and arrhythmia. Safety in pregnancy is unclear.

Papaverine was first isolated in 1848 from opium. Despite being from opium it contains no opioid activity. In the United States a 60 mg dose costs about 40 USD as of 2021.
