MEFROS FORTE TAB
MEFENAMIC ACID 250MG + PARACETAMOL 325MG
MEFROS FORTE TAB is a tablet of mefenamic acid 250 mg with paracetamol 325 mg. It is used for pain and fever — particularly period pain, headache, dental and musculoskeletal pain — combining an NSAID with particular efficacy in dysmenorrhoea and a central analgesic.
01
Benefits
- Mefenamic acid is especially effective in dysmenorrhoea, where prostaglandin-driven uterine contraction is the underlying mechanism.
- It also reduces menstrual blood loss, an advantage in women with heavy periods.
- Paracetamol adds central analgesia and antipyresis, allowing useful pain relief at a lower NSAID burden.
- Effective for dental pain, headache and musculoskeletal pain as well as period pain.
- Onset of relief is typically within an hour of a dose.

Stop and get medical help if any of these occur
- Severe or persistent diarrhoea — this is a reason to stop mefenamic acid, not to persist
- Black, tarry stools or vomiting of blood
- Yellowing of the skin or eyes
- Seizures, particularly in overdose
- Swelling of the face, lips or tongue, or difficulty breathing
- A marked fall in urine output
03
Precautions
- Diarrhoea with mefenamic acid can signal colitis and is an indication to stop the drug rather than continue.
- Mefenamic acid is particularly dangerous in overdose, causing seizures — an important consideration in patients at risk of self-harm.
- Contraindicated in active peptic ulcer disease, inflammatory bowel disease, and a history of gastrointestinal bleeding.
- Contraindicated in severe hepatic or renal impairment, and in NSAID hypersensitivity including aspirin-sensitive asthma.
- Check total daily paracetamol intake across all products before adding this one.
- Avoid in the third trimester of pregnancy; use earlier in pregnancy and while breastfeeding only on medical advice.
- Limit to short courses — mefenamic acid is not intended for prolonged use.
- Take with or after food, and avoid alcohol during the course.
