⚡ Quick Answer — What is Meftal-P?

Meftal-P is a mefenamic acid 100 mg tablet — the paediatric or low-dose strength of this fenamate-class NSAID. It is used for fever, mild-to-moderate pain, and menstrual pain. In children, the dose is weight-based (~6.5 mg/kg three times daily); adults typically take 2 to 3 tablets (200–300 mg) three times daily. Take with food. Mefenamic acid has a particularly strong evidence base for primary dysmenorrhoea (period pain), where it is among the most effective NSAIDs.

Meftal-P 100 mg is a tablet of mefenamic acid, a non-selective NSAID in the fenamate chemical class. The 100 mg strength is the paediatric dose tablet in many markets; it is also used at multi-tablet doses in adults when a low starting dose or fine titration is preferred. The adult high-strength form is the 250 mg and 500 mg Meftal tablet.

Mefenamic acid is notable for its strong effect on primary dysmenorrhoea (period pain). The pain mechanism of dysmenorrhoea is driven by uterine prostaglandin production, and mefenamic acid blocks both prostaglandin synthesis (COX inhibition) and prostaglandin action at the receptor — a dual mechanism that gives it a slight edge over ibuprofen in some head-to-head dysmenorrhoea trials.

What Is Meftal-P Used For?

  • Fever in children (paediatric use, weight-based dosing)
  • Mild-to-moderate pain in children and adults — headache, dental pain, musculoskeletal pain, post-vaccination soreness
  • Primary dysmenorrhoea — menstrual cramps (adults; use the 500 mg tablet at higher doses)
  • Menorrhagia — heavy menstrual bleeding, to reduce both bleeding volume and pain
  • Post-traumatic soft-tissue pain in older children
  • Juvenile idiopathic arthritis — specialist supervision

Meftal-P Dosing

  • Children ≥ 6 months to 14 years: approximately 6.5 mg/kg per dose, three times daily, after food. For a 15 kg child, that is one 100 mg tablet three times daily. Maximum course: 7 days.
  • Adolescents and adults: 200–300 mg (2–3 tablets) three times daily after food, maximum 7 days for acute indications. For dysmenorrhoea, the higher-strength 250 or 500 mg Meftal tablet is usually preferred.
  • Elderly: lowest effective dose; mefenamic acid is more prone to GI and renal effects in elderly patients.

Always take with food or milk. Swallow whole with water. Meftal-P tablets are small enough that they can usually be halved for paediatric weight-based dosing if necessary. For very young children, the paediatric suspension is often more convenient.

How Does Mefenamic Acid Work?

Mefenamic acid is a non-selective cyclooxygenase inhibitor (blocking both COX-1 and COX-2), reducing prostaglandin synthesis at sites of inflammation, injury, and within the uterus. Unlike other NSAIDs, mefenamic acid also has direct antagonist activity at prostaglandin receptors — which contributes to its particular effectiveness in period pain and uterine-mediated pain.

GI safety. Meftal-P (or its NSAID component) carries real risk of gastritis, peptic ulcer, and upper-GI bleeding. Risk is highest in patients over 65, in those with prior ulcer disease, and in anyone also on low-dose aspirin, corticosteroids, SSRIs, or anticoagulants. Take with food, at the lowest effective dose for the shortest reasonable time, and ask your doctor about adding a proton pump inhibitor (omeprazole, pantoprazole) for courses over 2–4 weeks.

Who Should Not Take Meftal-P?

  • Known hypersensitivity to mefenamic acid or any NSAID
  • Active peptic ulcer or history of GI bleeding
  • Inflammatory bowel disease flare (mefenamic acid is specifically associated with diarrhoea and colitis flares)
  • Severe heart failure, established ischaemic heart disease
  • Severe hepatic or renal impairment
  • Third trimester of pregnancy
  • Aspirin- or NSAID-induced asthma, urticaria, or angioedema

Side Effects

  • Common: diarrhoea (particularly characteristic of mefenamic acid — more than other NSAIDs), dyspepsia, nausea, abdominal pain, headache, dizziness, rash
  • Uncommon: peptic ulcer, GI bleeding, liver enzyme elevation, reduced kidney function, raised blood pressure
  • Rare but serious: severe colitis, haemolytic anaemia, acute kidney injury, Stevens-Johnson syndrome, seizures (particularly in overdose)

Stop mefenamic acid immediately if persistent or bloody diarrhoea develops — this is a known adverse reaction that does not always resolve simply by continuing therapy.

Frequently Asked Questions

What is Meftal-P used for?

Meftal-P (mefenamic acid 100 mg) is used for fever, mild-to-moderate pain, and menstrual pain. In children it is a weight-based fever and pain medicine; in adults it is used at 2–3 tablet doses or, more commonly, the higher-strength Meftal 250/500 mg is used.

Is Meftal-P only for children?

No — the 100 mg strength is labelled paediatric but is also used in adults when a fine dose titration or low dose is preferred. For adult dysmenorrhoea and pain, the 250 or 500 mg Meftal tablet is usually more practical.

How is mefenamic acid different from ibuprofen?

Both are non-selective NSAIDs. Mefenamic acid has a slight edge in dysmenorrhoea because it also blocks prostaglandin receptors directly. It is more prone to diarrhoea as a side effect and is usually used for shorter courses than ibuprofen.

How do I give Meftal-P to a child?

Dose is approximately 6.5 mg per kg of body weight, 3 times daily, after food, for up to 7 days. A 15 kg child gets roughly one 100 mg tablet three times daily. Always confirm with a paediatrician and use a scale — do not estimate weight.

Can I give Meftal-P on an empty stomach?

No — always give after food or milk. Mefenamic acid on an empty stomach often causes immediate indigestion.

Why does Meftal-P give some people diarrhoea?

Mefenamic acid has a specific, relatively common association with diarrhoea that is not shared to the same degree by other NSAIDs. The mechanism is not fully understood but is likely related to effects on intestinal prostaglandins. Persistent or bloody diarrhoea is a reason to stop.

How long should I take Meftal-P?

Short courses (up to 7 days) for acute pain or fever. For dysmenorrhoea, typically 2–3 days per menstrual cycle.

Is Meftal-P safe in pregnancy?

Avoid after 20 weeks; contraindicated in the third trimester. Use in early pregnancy only on medical advice; paracetamol is first-line.

Can my child have paracetamol and Meftal-P together?

Yes. They work on different pathways and can be alternated or combined at correctly-weighed paediatric doses. This is common practice for high persistent fever in children under paediatric supervision.

Can adults use Meftal-P for menstrual cramps?

Yes, although the 250 or 500 mg Meftal tablet is usually more convenient for adult dosing. At 100 mg, a typical adult starting dose is 2 tablets (200 mg) three times daily for the first 2–3 days of a cycle.

What if a child vomits after Meftal-P?

If vomiting occurs within 30 minutes of the dose, repeat the dose once. If vomiting occurs later than 30 minutes, do not repeat — most absorption has already happened. If vomiting is persistent, contact your paediatrician.
