Side effects and cautions

All SNRIs work in much the same way and generally can cause the same kinds of side effects. Some people may not have any side effects. Side effects that do occur are usually mild and go away after the first few weeks of treatment. Taking medicine with food may lessen upset stomach, a common side effect. If you can't handle the side effects of one SNRI, you may have fewer side effects with a different one, as each SNRI has a different chemical makeup.

The most common possible side effects of SNRIs include:

• Upset stomach.
• Dry mouth.
• Dizziness.
• Headache.
• Sweating.

Other possible side effects may include:

• Tiredness.
• Constipation.
• Trouble sleeping.
• Less sexual desire or trouble reaching orgasm.
• Loss of appetite.

The benefits of antidepressants typically outweigh the possible side effects when depression is severe. Which antidepressant is best for you depends on several factors, such as your symptoms and any other health conditions you may have.

Ask your healthcare professional or pharmacist about the most common possible side effects for your specific medicine. Read the patient medication guide that comes with the prescription.
