Effexor Patient Information including How Should I Take

What should I discuss with my healthcare provider before taking venlafaxine (Effexor)?

Do not take this medication if you are allergic to venlafaxine, or if you are also using a monoamine oxidase inhibitor (MAOI) such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate). You must wait at least 14 days after stopping an MAOI before you can take venlafaxine. After you stop taking venlafaxine, you must wait at least 7 days before you start taking an MAOI.

Before taking venlafaxine, tell your doctor if you are allergic to any medications, or if you have:

bipolar disorder (manic depression);
cirrhosis or other liver disease;
kidney disease;
high blood pressure;
glaucoma;
seizures or epilepsy;
a bleeding or blood clotting disorder; or
high cholesterol.

If you have any of the conditions listed above, you may need a dose adjustment or special test to safely take venlafaxine.

You may have thoughts about suicide when you first start taking an antidepressant, especially if you are younger than 24 years old. Tell your doctor if you have worsening symptoms of depression or suicidal thoughts during the first several weeks of treatment, or whenever your dose is changed.

Your family or other caregivers should also be alert to changes in your mood or symptoms. Your doctor will need to check you at regular visits for at least the first 12 weeks of treatment.

FDA pregnancy category C. Venlafaxine may be harmful to an unborn baby, and may cause problems in a newborn baby if the mother takes the medication late in pregnancy (during the third trimester). Tell your doctor if you are pregnant or plan to become pregnant during treatment.

Venlafaxine can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Do not give this medication to anyone under 18 years old without the advice of a doctor.

How should I take venlafaxine (Effexor)?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Your doctor may occasionally change your dose to make sure you get the best results from the medication. Follow the directions on your prescription label.

Take this medication with a full glass of water.

Venlafaxine should be taken with food.

Swallow the controlled-release capsule (Effexor XR) whole, without crushing or chewing. To make the medication easier to swallow, you may open the capsule and sprinkle the medicine into a small amount of applesauce. Swallow all of the mixture without chewing, and do not save any for later use.

Try to take venlafaxine at the same time each day.

It may take 4 weeks or more for your symptoms to improve. For best results, keep using the medication as directed. Do not stop using venlafaxine without first talking to your doctor. You may have unpleasant side effects if you stop taking this medication suddenly.

Store venlafaxine at room temperature away from moisture and heat.
