How Merispas Tablet works

Merispas Tablet is a combination of two medicines: Dicyclomine and Mefenamic Acid. Dicyclomine is an anticholinergic that works by relaxing the muscles in the stomach and intestines. It stops sudden muscle contractions (spasms), thereby relieving cramps, pain, bloating, and discomfort. Mefenamic Acid is a non-steroidal anti-inflammatory drug (NSAID). It works by blocking the release of certain chemical messengers that cause pain and inflammation. Together, these medicines help relieve menstrual cramps and stomach cramps.
