What are two common adverse drug reactions?

Nausea and dizziness are indeed common adverse drug reactions that many patients experience when taking various medications. These symptoms can arise due to a range of pharmacological effects, such as the drug's interaction with the central nervous system or its effects on the gastrointestinal tract.

Nausea is often a result of medications irritating the stomach lining or affecting neurotransmitter systems that regulate nausea. Dizziness can stem from changes in blood pressure, sedation, or disturbances in balance that some medications can cause. Both reactions can significantly impact a patient's quality of life and adherence to prescribed therapies, making their identification and management critical in clinical practice.

While headache and rash, fatigue and insomnia, and dry mouth and constipation are also adverse reactions that medications can produce, nausea and dizziness are particularly notable for their frequency and impact across a wide array of drug classes.
