What is mefenamic acid used for (and what does it treat)?
Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation from conditions such as:
- Menstrual pain (dysmenorrhea)
- Mild to moderate pain, including headache, dental pain, muscle/joint pain, and back pain
How is tab mefenamic acid usually taken?
Tablets are typically taken by mouth with food to reduce stomach irritation. Dosing depends on age, the condition being treated, and local prescribing guidance.
What conditions is it not for?
Mefenamic acid is not used to treat infections or fever caused by bacteria. It also is generally not used for long-term pain control unless a clinician specifically directs it.
What side effects do people ask about?
Common concerns with mefenamic acid (like other NSAIDs) include:
- Stomach upset, heartburn, nausea
- Stomach pain
- Risk of ulcers or bleeding with longer use or higher doses
Seek urgent medical help if there are signs of bleeding (such as black/tarry stools or vomiting blood) or severe allergic reactions.
Who should be careful or avoid it?
Extra caution is needed (and many people should avoid NSAIDs) if you have a history of:
- Stomach ulcers or gastrointestinal bleeding
- NSAID allergy/asthma triggered by NSAIDs
- Serious kidney disease
- Significant heart disease or have been told to avoid NSAIDs
Also, NSAIDs can be risky later in pregnancy.
If you tell me your exact “Tab” strength, I can narrow it down
Mefenamic acid tablets come in different strengths. If you share the strength (for example, 250 mg or 500 mg) and what you’re using it for, I can explain the usual purpose and how it’s commonly taken for that specific use.
