Ponstan (Mefenamic Acid) Tablets – Complete Guide: Uses, Dosage, Side Effects & Precautions

 

Ponstan (Mefenamic Acid) Tablets - Introduction

Ponstan is a well-known brand name for mefenamic acid, a medication that belongs to the class of non-steroidal anti-inflammatory drugs (NSAIDs). It is widely used for treating pain, inflammation, and menstrual cramps. Due to its powerful anti-inflammatory and analgesic effects, Ponstan is a common prescription in many countries for short-term relief of moderate pain.

What is Ponstan (Mefenamic Acid)?

Ponstan contains mefenamic acid as its active ingredient. It works by inhibiting prostaglandin synthesis, chemicals in the body that are responsible for causing pain, fever, and inflammation. The drug is especially effective in treating menstrual pain, making it a go-to solution for many women worldwide.



Uses of Ponstan Tablets

Ponstan is prescribed for various types of pain, including:

  • Primary dysmenorrhea (menstrual cramps)

  • Muscle and joint pain

  • Dental pain (toothaches)

  • Headaches and migraines

  • Fever and general body pain

  • Post-operative pain

  • Arthritis-related inflammation

It is often considered when common over-the-counter medications like ibuprofen or paracetamol fail to provide sufficient relief.





















How Does Ponstan Work?

Ponstan works by blocking the cyclooxygenase (COX) enzyme, which is responsible for the production of prostaglandins. These prostaglandins are mediators of inflammation, pain, and fever in the body. By reducing their levels, Ponstan helps in relieving pain and reducing inflammation.
