Naproxen belongs to a class of pharmaceuticals known as non-steroidal anti-inflammatory drugs (NSAIDs). Period Pain Reliever is a medication that is used to treat period symptoms (also known as menstrual pain or dysmenorrhoea) in women between the ages of 18 and 50.
Naproxen is the active ingredient. Each pill contains 250 mg of the active ingredient.
The pill is gastro-resistant, which means it has a coating that prevents it from dissolving in the stomach, allowing the naproxen to be released farther down in your intestine.
