Why is Serzone prescribed?

Possible symptoms include changes in appetite, weight, sleep habits, and mind/body coordination, increased fatigue, feelings of guilt or worthlessness, difficulty concentrating, slowed thinking, and suicidal thoughts.

Most important fact about Serzone

It may be several weeks before you feel the full antidepressant effect of Serzone. Once you do begin to feel better, it is important to keep taking the drug.

How should you take Serzone?

Take Serzone exactly as prescribed by your doctor even if you no longer feel depressed. Your doctor should check your progress periodically.

Take it as soon as you remember. If it is within 4 hours of your next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at once.

Why should Serzone not be prescribed?

If you are sensitive to or have ever had an allergic reaction to Serzone or similar drugs, such as Desyrel, you should not take this medication. You should also avoid it permanently if previous treatment had to be stopped due to signs of liver injury.

Serious, sometimes fatal reactions have occurred when Serzone is used in combination with drugs known as MAO inhibitors, including the antidepressants Nardil and Parnate. Never take Serzone with one of these drugs; and do not begin therapy with Serzone within 14 days of discontinuing treatment with one of them. Also, allow at least 7 days between the last dose of Serzone and the first dose of an MAO inhibitor.

Serzone should also be avoided if you are taking Halcion or Tegretol, and should never be combined with Orap, as heart problems could result.

Special warnings about Serzone

Your doctor will prescribe Serzone with caution if you have a history of seizures or mania (extreme agitation or excitability) or heart or liver disease. Serzone should also be used with caution if you have had a heart attack, stroke, or angina; take drugs for high blood pressure; or suffer from dehydration. Under these circumstances, Serzone could cause an unwanted drop in blood pressure. Be sure to discuss all of your medical problems with your doctor before taking this drug.

Serzone has also been known to produce very rare cases of potentially fatal liver failure. Ordinarily, the drug is not prescribed for people with liver disease, and your doctor may periodically test your liver function. If you develop warning signs of liver problems--such as loss of appetite, stomach upset, a generally ill feeling, or yellowing of the skin and eyes--alert your doctor immediately. Treatment with Serzone will probably have to be stopped.

Serzone may cause you to become drowsy or less alert and may affect your judgment. Do not drive or operate dangerous machinery or participate in any hazardous activity that requires full mental alertness until you know how the drug affects you.

Before having surgery, dental treatment, or any diagnostic procedure requiring anesthesia, tell the doctor or dentist you are taking Serzone. If you develop an allergic reaction such as a skin rash or hives while taking Serzone, notify your doctor. If you are male and experience a prolonged or inappropriate erection while taking Serzone, discontinue this drug and call your doctor.

If you have ever been addicted to drugs, tell your doctor before you start Serzone.
