Antidepressants and Possible Side Effects

There are some less common antidepressants that are chemically different from the other antidepressants. They work by blocking the reuptake of the chemical messengers serotonin and norepinephrine. This leaves more of these neurotransmitters between the sending and receiving neurons. The result is less depression.

Possible Side Effects of Other Antidepressants


Not all of the less common antidepressants produce all of these side effects, and not everyone who takes these medications experiences all of them. Some people don't have any. Some side effects disappear quickly, while others remain throughout treatment. Elderly patients may be more sensitive to the effects of these medications. If you are not sure your symptoms are from the medication, call your doctor. Many people will experience some of these symptoms without having taken any medication.
