Doctors may prescribe SSRIs when mood problems are a major symptom of fibromyalgia.

Side Effects

All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

Here are some important things to think about:

• Usually the benefits of the medicine are more important than any minor side effects.
• Side effects may go away after you take the medicine for a while.
• If side effects still bother you and you wonder if you should keep taking the medicine, call your doctor. He or she may be able to lower your dose or change your medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.

Call 911 or other emergency services right away if you have:

• Trouble breathing.
• Hives.
• Swelling of your face, lips, tongue, or throat.

Call your doctor if you have:

• Thoughts of suicide.
• Agitation and restlessness.
• Seizures.
• Fast heartbeat.
• Nausea and vomiting.

Common side effects of this medicine include:

• Loss of sexual desire or ability.
• Irritability.
• Trouble sleeping or drowsiness.
• Headache.
• Changes in appetite.

FDA advisories. The U.S. Food and Drug Administration (FDA) has issued:

• An advisory on antidepressant medicines and the risk of suicide in children and adults. The FDA does not recommend that people stop using these medicines. Instead, a person taking antidepressants should be watched for warning signs of suicide. This is especially important at the beginning of treatment or when doses are changed.
• A warning about taking triptans, used for headaches, with SSRIs (selective serotonin reuptake inhibitors) or SNRIs (selective serotonin/norepinephrine reuptake inhibitors). Taking these medicines together can cause a very rare but serious condition called serotonin syndrome.
