Description

Naprosyn Pain Relief Gastro-Resistant Tablets 250mg 9 Tablets

Naprosyn Pain Relief contains naproxen 250mg, a non-steroidal anti-inflammatory drug (NSAID) used to relieve the pain associated with period pain (dysmenorrhoea). It is available as gastro-resistant tablets, which are designed to be gentler on the stomach.

How It Works

Naproxen works by blocking the production of natural chemicals in your body called prostaglandins. Prostaglandins are released during your period and cause the pain and cramping you feel. By reducing the levels of these chemicals, naproxen helps to relieve pain and discomfort.

Directions for Use

Naprosyn Pain Relief Gastro-Resistant Tablets are for use in women aged 15 years and over. The recommended starting dose is two tablets (500mg) taken together, followed by one tablet (250mg) every 6 to 8 hours as needed. Do not take more than three tablets (750mg) in any 24-hour period. Swallow the tablets whole with a glass of water — do not crush or chew them. It is best to start taking them when your period pain begins. Always read the patient information leaflet before use. If you are unsure about the correct dose, speak to your PillSorted pharmacist.
