About Effexor

Effexor (venlafaxine) is a serotonin-norepinephrine reuptake inhibitor (SNRI) class drug used to treat depression. It is manufactured by Wyeth and it is currently the sixth-most prescribed medication for depression in the United States.

Testing

• In clinical trials, Effexor has similar effects when treating depression as amitriptyline but seems to be better tolerated. However, it is not as effective as newer drugs such as Lexapro, and people taking Effexor are more prone to side effects.

Other Uses

• Besides treating depression, some doctors will prescribe Effexor for the treatment of migraines, for hot flashes in menopausal women and for people with diabetic neuropathy.

Side Effects

• The most common side effects experienced by people taking Effexor are nausea, headache, insomnia, sexual issues, dizziness and sweating. Some people taking high doses of Effexor suffer from memory loss.

Risk Factors

• People on Effexor are at increased risk of developing glaucoma. Also, studies indicate that people taking Effexor experience a 1.6 percent increased risk of committing suicide. There is no data on Effexor's effect on pregnant women.

Discontinuation

• Though there is no biological evidence for dependence, some people who discontinue use of Effexor will experience symptoms of withdrawal. This may depend on the dosage, as people on higher doses may find it harder to stop taking the drug.
