Some prescription medications used for nausea are Tigan oral and Tigan intramuscular, which has the generic name of trimethobenzamide HCL, relates WebMD. However, there are many other medications for nausea that are over-the-counter, and they include Dramamine, Bonine, Emetrol and Pepto-Bismol, explains MedicineNet. Before taking any of these medications, people should see their doctors who can evaluate and diagnose the exact cause for the nausea.
Nausea or vomiting medications are known as antiemetics. For mild nausea or nausea associated with motion sickness, doctors may recommend over-the-counter medications. Prescribed medication for nausea may be necessary for other reasons. For example, Tigan is used for nausea that occurs after surgery or is caused by gastroenteritis, reports the National Institutes of Health. This prescribed medication comes as a capsule, injection or suppository.
