Yes, you can take Meftal 250 mg (which contains Mefenamic Acid) to help reduce a fever, as it is a nonsteroidal anti-inflammatory drug (NSAID) with fever-lowering properties. However, paracetamol is generally preferred as the first-line treatment for fever because it has a safer side-effect profile. If you choose to take Meftal 250 mg, always take it after food to prevent stomach irritation. Avoid this medication if you have a history of stomach ulcers, asthma, kidney issues, or if you are pregnant. If your fever lasts more than 3 days, please consult a doctor for a proper evaluation.

For a 13-year-old girl, the standard dosage of Meftal 250 mg (Mefenamic Acid) is typically one tablet (250 mg) taken up to three times daily, as needed for pain or fever. Always administer this medication after meals or with milk to prevent stomach upset. Since pediatric dosages depend heavily on body weight and the specific condition being treated, it is highly recommended to consult a pediatrician for a precise prescription. Do not exceed the recommended dose, and do not use it for more than 3 consecutive days without medical supervision.

Meftal (Mefenamic acid) only helps lower fever temporarily; it does not cure the underlying infection. I cannot recommend an antibiotic because antibiotics only treat bacterial infections, not viral ones. Misusing antibiotics can lead to harmful side effects and drug resistance. Since your fever is not responding to Meftal, you need a proper medical evaluation to find the root cause. Please consult a doctor immediately. They can perform necessary tests (like a blood test) to diagnose the infection and prescribe the correct, targeted treatment. For now, please stay well-hydrated, rest, and avoid self-medicating with antibiotics.
