Nausea can be very unpleasant. While it is a common symptom that may not immediately catch your attention, it can sometimes be a warning sign of something more serious. Here’s all you need to know about it.
Nausea feels as though you are about to throw up. You may feel discomfort in the stomach or the back of the throat. Vomiting may or may not follow. It is very common and happens to everyone, both children and adults, from time to time.

Common antiemetics include dimenhydrinate, prochlorperazine, promethazine, metoclopramide, and ondansetron.

If nausea is one of the side effects of the medicines you are taking, inform your doctor or pharmacist when it becomes intolerable. They will help you make the most suitable choice in changing the medicines.
There are some medications that you can take beforehand, to avoid general nausea. These include hyoscine.
