Ponstan (Mefenamic Acid) is a tablet that should be taken orally as prescribed by your doctor, typically 4 times daily. It is recommended to take the tablet with a full glass of water (8 ounces/240 milliliters), unless directed otherwise by your doctor. After taking the medication, do not lie down for at least 10 minutes. If you experience stomach upset, taking the medication with food or milk is advised. Avoid taking mefenamic acid with antacids, unless advised otherwise by your doctor, as certain antacids can affect the absorption of the medication.
The dosage and length of treatment are based on your medical condition and response to treatment. To reduce your risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest possible time. Do not increase your dose or use this drug more often or for longer than prescribed. Ponstan usually should not be taken for more than 7 days at a time.
The standard adult dosage (for individuals aged 14 years or older) for the initial dose is 500 mg, followed by 250 mg every six hours as required, not exceeding a week of therapy. For menstrual cramps, treatment typically does not need to be prolonged for more than two or three days.
