Nausea is an overwhelming sensation in the stomach that makes you feel the need to vomit. This condition can be short-lived or prolonged, and is has both physical and psychological origins. Nausea can stem from conditions in the brain, or problems in the upper gastrointestinal tract. There are medications that can prevent this condition and help you avoid symptoms when caused by pains, motions or diseases. Do not take any medications before consulting with a medical professional.
Bismuth Subsalicylate
Bismuth subsalicylate helps treat vomiting and nausea caused by viral infections, and works by coating the stomach lining. Side effects can cause your stool or tongue to turn dark, and older adults that have health problems should avoid taking this medication.
Antihistamines
Antihistamines can prevent nausea caused by motion sickness by dulling the inner ear's motion sensors. This medication is able to block the part of the brain that controls nausea and needs to be taken before motion sickness occurs. Antihistamines can make you feel sleepy and affect your ability to operate machinery.
