What should you know about anti nausea?

There is no single product suited to every type of nausea. A clinician or pharmacist considers the likely trigger and selects a medicine only when its benefits and cautions fit the situation.

Nausea is a symptom, not a diagnosis. Gastroenteritis commonly presents with nausea, vomiting or diarrhoea, while acid reflux may present with nausea alongside burning discomfort or sour fluid in the mouth. Gallstones can present with nausea and upper abdominal pain.

Different antiemetic medicines act on different nerve signals. Possible effects include sleepiness, headache, constipation, restlessness or changes in heart rhythm, depending on the medicine. Treating nausea must not delay attention to dehydration, infection or acute abdominal disease.

Take frequent small sips of fluid and choose plain, light food when tolerated. Avoid strong smells, large fatty meals and lying flat soon after eating. If vomiting is present, focus first on retaining fluids.

Before using a medicine, check the active ingredient and ask whether it is compatible with pregnancy, breastfeeding, heart conditions and regular prescriptions. Follow the stated dose; taking more can increase harm without treating the cause.

Seek urgent medical care for severe or worsening abdominal pain, chest pain, confusion, a stiff neck with severe headache, vomiting blood, green vomit, black stools, fainting or difficulty breathing. Sudden sweating, weakness and nausea can accompany hypoglycaemia in a person using glucose-lowering treatment and require immediate action according to their care plan.

Prompt assessment is also appropriate when fluids will not stay down, urine becomes very limited, the mouth is markedly dry, or nausea persists or keeps returning. Babies, older adults and pregnant people can become unwell more quickly.

Ask what may be causing the nausea, which medicine suits that cause, how it may affect alertness and what interactions to watch for. Clarify how long to try it and which new symptoms mean treatment should stop.
