1. Nausea and Stomach Upset

It’s not uncommon to feel queasy or experience stomach discomfort when starting anxiety medications, especially SSRIs and SNRIs. These side effects are usually most noticeable during the first few weeks of treatment as your body adapts to the medication. The nausea may manifest as a persistent unsettled stomach, reduced appetite, or even occasional vomiting. Staying hydrated, eating smaller meals, and avoiding spicy or greasy foods can help manage these symptoms. For most people, nausea subsides over time, but if it persists, discussing alternative medications or dosage adjustments with your doctor may be necessary.
