Medicine Reaction, Nausea and Vomiting

Many nonprescription and prescription medicines can cause nausea or vomiting. A few examples are:

• Antibiotics.
• Antidepressants.
• Aspirin, ibuprofen (such as Advil or Motrin), and naproxen (such as Aleve).
• Medicines used to treat cancer (chemotherapy).
• Opioid pain medicines.
• Vitamins and mineral supplements, such as iron.

Starting a new medicine or increasing the dose can cause nausea and vomiting. Nausea and vomiting also may mean that there is too much medicine in your body, even if you took it properly.
