You should stop giving Meftagesic and consult a pediatrician immediately. Using this combination medication (paracetamol and mefenamic acid) for more than three days without medical supervision is not recommended, as prolonged use can increase the risk of stomach irritation and kidney strain. Additionally, a fever persisting for three days requires a proper medical evaluation by a doctor to identify and treat the underlying infection, rather than just continuing to suppress the fever. Please do not switch to another medication without professional guidance.

Yes, it is generally safe to take mefenamic acid and paracetamol together, as they work differently to relieve pain. This combination is frequently prescribed for moderate pain, such as menstrual cramps or dental pain. However, you must strictly follow the recommended dosages. Avoid taking any other products containing paracetamol or NSAIDs (like ibuprofen) at the same time to prevent an accidental overdose, which can damage your liver or stomach. Always take this combination with or after food to minimise stomach irritation.
