What is in this leaflet
This leaflet answers some common questions about PONSTAN.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What PONSTAN is used for
PONSTAN is used to relieve the symptoms of period pain and treat heavy periods.
It also provides short term relief of pain in conditions such as:
- muscle and joint injuries such as sprains, strains and tendonitis
- dental pain.
PONSTAN containing mefenamic acid belongs to a group of medicines called Non-Steroidal Anti-Inflammatory Drugs (or NSAIDs). These medicines work by relieving pain and inflammation.
Although PONSTAN can relieve the symptoms of pain and inflammation, it will not cure your condition.
Your doctor may have prescribed PONSTAN for another reason.
Ask your doctor if you have any questions about why PONSTAN has been prescribed for you.
PONSTAN is not addictive.
