If Metrogyl is not helping your upset stomach, stop taking it and focus on light, bland meals and plenty of fluids. You can try a probiotic to help settle your stomach. If pain, diarrhoea, or bloating continues, see a doctor to find the cause and get the right treatment.

If you developed loose motions and stomach pain after taking Metrogyl 400, drink plenty of fluids and ORS to stay hydrated and eat non-spicy food. If loose motions are severe or do not improve in a day or two, see a doctor.
