Serzone

Serzone was an antidepressant medication. It affects chemicals in the brain that may become unbalanced and cause depression. Serzone has been discontinued, but generic nefazodone is available.

Serzone is used to relieve symptoms of depression such as feelings of sadness, worthlessness, or guilt; loss of interest in daily activities; changes in appetite; tiredness; sleeping too much; insomnia; and thoughts of death or suicide.

Serzone may also be used for purposes other than those listed in this medication guide.

Take Serzone exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain the instructions to you.

Take each dose with a full glass of water.

Do not stop taking Serzone without first talking to your doctor. It may be several weeks before you begin to feel better, and you may require continuous treatment for quite some time.

Store Serzone at room temperature away from moisture and heat.

Do not take Serzone if you have taken a monoamine oxidase inhibitor (MAOI) such as isocarboxazid (Marplan), phenelzine (Nardil), or tranylcypromine (Parnate) in the last 14 days, or if you are taking terfenadine (Seldane, Seldane-D), astemizole (Hismanal), cisapride (Propulsid), pimozide (Orap), triazolam (Halcion), or carbamazepine (Tegretol, Tegretol XR, Epitol, Carbatrol).

In rare cases, treatment with Serzone has been associated with serious liver problems, sometimes resulting in liver transplant or death. Contact your doctor immediately if you experience yellowing of the skin or eyes; unusually dark urine; loss of appetite that lasts several days or longer; severe nausea; or stomach pain. These may be early signs of liver problems.

Some young people have thoughts about suicide when first taking an antidepressant. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.

Use caution when driving, operating machinery, or performing other hazardous activities. Serzone may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities.

Dizziness may be more likely to occur when you rise from a sitting or lying position. Rise slowly to prevent dizziness and a possible fall.

Avoid alcohol during treatment with Serzone. Alcohol may increase drowsiness and dizziness while taking Serzone.
