These tablets contain 250 mg of naproxen. This medicine is used to treat period pain (also called menstrual pain or dysmenorrhoea).  Naproxen belongs to a group of painkillers called Non-Steroidal Anti-inflammatory Drugs (also called NSAIDs).  Other medicines in this group include ibuprofen and aspirin.


Only take this medicine if you are between 15 and 50 years old.

Ask your doctor, pharmacist or nurse if you need more information.

 First day:

• When the pain starts, take two tablets

• Then after 6 to 8 hours, take one more tablet that day, if you need it

Second day:

• Take one tablet every 6 to 8 hours if needed

Third day:

• Take one tablet every 6 to 8 hours if needed

Do not take more than 3 tablets each day.

Always take the lowest effective dose for you. Do not take more than the recommended dose of up to three tablets in a day. Do not take for longer than three days in any one month (menstrual cycle).

Taking the tablets:

• Swallow the tablets whole with a drink of water. Do not chew or crush them

• Take the tablets with or after food

• Only take the tablets for as long as you need them for the period pain.

You may not need to take the tablets all the time for all 3 days. If you still have pain after 3 days of treatment, talk to your doctor. Do not take the tablets for more than 3 days in any one period (cycle)

If you see a doctor, pharmacist or nurse or go into hospital, tell them you are taking this medicine

If you (or someone else) takes too many tablets, go to the nearest hospital casualty department or your doctor straight away.

Each white round coated tablet contains 250 mg of naproxen, which is the active medicine.  The tablet is gastroresistant (also known as enteric coated). This means that it is covered with a coating which stops the tablet dissolving in the stomach, so that the naproxen is released further down in your gut.

The tablets also have inactive contents: lactose, maize starch, polyvidone, sodium starch glycollate and magnesium stearate. Also, the coating contains colloidal silicon dioxide, polyvinyl acetate phthalate, polyethylene glycol, stearic acid, hydroxypropyl methylcellulose, sodium alginate, sodium bicarbonate, purified talc, triethyl citrate, the colour titanium dioxide (E171) and black printing ink.
