Antidepressants


Antidepressants are medicines that treat depression. Your doctor can prescribe them for you. They work to balance some of the natural chemicals in our brains. It may take several weeks for them to help. There are several types of antidepressants. You and your doctor may have to try a few before finding what works best for you.

Antidepressants may cause mild side effects that usually do not last long. These may include headache, nausea, sleep problems, restlessness, and sexual problems. Tell your doctor if you have any side effects. You should also let your doctor know if you take any other medicines, vitamins, or herbal supplements.

It is important to keep taking your medicines, even if you feel better. Do not stop taking your medicines without talking to your doctor. You often need to stop antidepressants gradually.
