This combination helps reduce muscle cramps and inflammation causing the pain.

• Meftal-Spas Tablet is commonly used for menstrual cramps and abdominal pain.
• It should be taken as prescribed by a doctor, considering your medical condition.
• Possible side effects include nausea, vomiting, diarrhea, dry mouth, and weakness; consult your doctor if these persist.
• Avoid alcohol while taking this medication as it may increase drowsiness and risk of stomach bleeding.
• If you are pregnant, breastfeeding, or have other health concerns, discuss with your doctor before use.
