Effexor

Like all antidepressants, Effexor could cause episodes of mania (abnormally high feelings of excitement and energy). If you experience a major depressive episode, there's a slight chance that it could be the first signs of bipolar disorder. Tell your doctor about all your symptoms, and note that Effexor is not approved for treating bipolar depression.

Your doctor will prescribe Effexor with caution if you have high blood pressure; heart, liver, or kidney disease; or a history of seizures or mania. You should discuss all of your medical problems with your doctor before taking Effexor.

Effexor sometimes causes an increase in blood pressure. If this happens, your doctor may need to reduce your dose or discontinue the drug.

Effexor also tends to increase the heart rate, especially at higher doses. Use Effexor with caution if you've recently had a heart attack, suffer from heart failure, or have an overactive thyroid gland.

Effexor may also cause cholesterol levels to rise in some patients who take it for 3 months or longer. This effect is more common among patients taking higher doses of Effexor.

Antidepressants such as Effexor may cause fluid retention, especially if you are an older adult.

Effexor may cause you to feel drowsy or less alert and may affect your judgment. Therefore, avoid driving or operating dangerous machinery or participating in any hazardous activity that requires full mental alertness until you know how this drug affects you.

Your doctor will check you regularly if you have glaucoma (high pressure in the eye), or you are at risk of developing it.

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

If you develop a skin rash or hives while taking Effexor, notify your doctor. Effexor may also cause bleeding or bruising of the skin.

Do not stop taking the drug without consulting your doctor. If you stop suddenly, you may have withdrawal symptoms, even though this drug does not seem to be habit-forming. Your doctor will have you taper off gradually.
