Summary
Papaverine is used to treat smooth muscle spasms, which are involuntary muscle contractions, and certain blood vessel disorders, which affect the flow of blood through the body. It helps improve blood flow and reduce spasms, providing relief from symptoms associated with these conditions.
Papaverine works by relaxing smooth muscles in blood vessels, which are the muscles that line the walls of blood vessels. This relaxation improves blood flow and reduces muscle spasms, helping to alleviate symptoms related to poor circulation and muscle contractions.
Papaverine is usually taken by mouth in tablet form. The typical starting dose for adults is 150 mg to 300 mg, taken three to five times a day. The maximum recommended dose is 600 mg per day. Always follow your doctor's specific dosing instructions.
Common side effects of papaverine include dizziness, which is a feeling of being unsteady, flushing, which is a sudden reddening of the skin, and low blood pressure, which is when your blood pressure drops too low. These effects are generally mild and may go away on their own.
Papaverine can cause low blood pressure and liver problems, which can be serious. It should not be used if you have a known allergy to it or complete heart block, which is a type of heart rhythm disorder. Always inform your doctor of your medical history before starting papaverine.
