Understanding Mefenamic Acid: Your Trusted Pain Relief Partner
Mefenamic Acid is a powerful non-steroidal anti-inflammatory drug (NSAID) that has been helping Filipinos manage various types of pain for decades. As an essential medicine listed in the Philippine National Formulary 8th Edition, you can trust that this is a government-approved, evidence-based treatment for pain management and inflammation.

How Mefenamic Acid Works (Simple Explanation)
Imagine your body has a "pain alarm system" that goes off when you have inflammation or injury. Mefenamic Acid works like a smart security guard—it blocks the production of chemicals called prostaglandins that trigger pain, swelling, and fever. This means:

  • Less pain from menstrual cramps, arthritis, headaches, and dental issues
  • Reduced inflammation in joints and muscles
  • Lower fever when you're feeling hot and unwell
  • Quick relief so you can continue with your daily activities
It's like having a reliable "off switch" for your body's pain signals—effective yet gentle when used correctly.

  • Seryoso: Itim na dumi, pagsusuka ng dugo, matinding pananakit ng ulo—tawagin agad ang doktor
  • IMPORTANTE: Laging inumin kasama ng pagkain para protektahan ang sikmura. Huwag lumampas sa prescribed dose
  • Paalala: Kung may asthma, problema sa bato, o buntis (lalo na 3rd trimester), sabihin sa doktor

Paalala: Ang Mefenamic Acid ay para sa short-term pain relief (karaniwang 3-5 araw para sa menstrual pain). Kung hindi nawala ang sakit pagkatapos ng isang linggo o lumala pa, kumonsulta agad sa doktor. Hindi ito para sa pang-araw-araw na paggamit nang walang supervision ng doktor.
