Does Ponstan stop bleeding?


Ponstan and Pontalon are the common brand names for mefenamic acid. It is widely available in the market as a painkiller to relieve fever and pain. In this article, we will discuss a frequently asked question, ‘does Ponstan stop bleeding?’.

What is ponstan?

Ponstan is a mefenamic acid belonging to the class of medication known as nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing the chemical prostaglandin in our body that causes fever, pain, swelling and inflammation.

Ponstan is available as oral tablets, capsules and syrup. It is used as a short-term treatment of not more than 7 days due to its side effects.

Uses of ponstan

Ponstan is used to relieve fever and mild-to-moderate pain caused by a wide range of conditions as below:

  • Muscular pain
  • Joint pain due to osteoarthritis of rheumatoid arthritis
  • Pain due to sprain, strain or fracture
  • Toothache
  • Headache
  • Pain following childbirth
  • Pain following surgery
  • Menstrual pain

Does ponstan stop bleeding?

Apart from relieving pain, ponstan also works by reducing heavy menstrual bleeding. By opposing the production and action of prostaglandin in the wall of the uterus, it decreases blood loss by 30-50% in women suffering from heavy menstrual bleeding.

However, long-term treatment with ponstan at a high dose might bring detrimental effects. Prostaglandin plays a protective role in the stomach and intestine to form a protective layer that prevents erosion from stomach acid. As ponstan decreases the activity of prostaglandin, it increases the risks of the ulcer, bleeding and perforation. The risk is even higher in an existing case of stomach or intestinal ulcer.

Do contact your doctor immediately if you experience the following symptoms: vomiting blood, bloody or black tarry stool, skin or eyes turning yellow, or severe stomach pain. It might be a sign of internal bleeding. It is a life-threatening emergency which requires immediate treatment.
