For adults, the usual dose is 2.5 mg to 5 mg taken 3 to 4 times a day, preferably 30 minutes before meals. You can take it with or without food, but taking it before meals works best for stomach-related issues.
If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, just skip the missed one and continue your normal schedule. Do not take a double dose to make up for the one you missed.
Always buy from a licensed pharmacy, not roadside sellers, to make sure you are getting the genuine product. Be careful when driving or operating machines as this drug can make you drowsy or blur your vision. In hot weather, this medicine can reduce your sweating, so drink plenty of water to avoid overheating.
Avoid taking with antihistamines like chlorpheniramine (Piriton) as it can increase drowsiness and dry mouth. Do not combine with other stomach-relaxing drugs like hyoscine (Buscopan) without your doctor's advice. Alcohol can make the drowsiness worse, so avoid drinking while using this medicine.
