Emeset Tablet dosage

Emeset Tablet should be taken 30 minutes before the start of chemotherapy, 1-2 hours before the start of radiation therapy, or 1 hour before surgery, if used for those purposes. It can be taken with or without food, as advised by your doctor. If using the mouth-dissolving tablet, keep it in the mouth; it will dissolve within seconds, then swallow with saliva and drink water afterward. For the regular tablet, swallow it whole with a glass of water; do not break, crush, or chew it. Try to take the medicine at the same time each day. If you vomit within one hour of taking the mouth-dissolving tablet, take the same dose again. Avoid eating heavy meals before taking this medicine; eat small snacks or light foods and drink water to avoid dehydration. Continue taking it for as long as your doctor advises, even if you start to feel better. It is not recommended for children below 4 years of age unless prescribed by a paediatrician.
