Effexor XR (venlafaxine) for Depression in Multiple Sclerosis

Depression is a common and well documented symptom ofĀ multiple sclerosis. Effexor XRĀ (venlafaxine) belongs to a group of medications called selective serotonin and norepinephrine reuptake inhibitors (SSNRI). The drugĀ increasesĀ serotonin and norepinephrine, which are natural substances that positively affect communication between nerve cells or restore chemical balances in the brain.Ā The drugĀ is used to treat depression and types of anxiety that include generalized anxiety disorder, social anxiety disorder, and panic disorder.

Effexor XR is an extended-release capsule to be taken orally. It should be ingestedĀ once daily with food at the same time every day.Ā The drugĀ controls depression but does not cure it. It may take six to eight or more weeks before patients experience the full benefit. Patients should not stop taking the drugĀ suddenly because sudden discontinuation will likelyĀ causeĀ withdrawal symptoms that may include agitation, anxiety, emotional disorders, lack of coordination, sleeping disorders, gastric disorders, dry mouth, sweating, ringing in the ears, seizures and/or burning, tingling, numbness or electric shock-like feelings in the body.

Some of the most common Effexor XRĀ side effects are vision changes, nausea, vomiting, diarrhea, changes in appetite or weight, dry mouth, yawning, dizziness, headache, anxiety, feeling nervous, fast heartbeats, tremors or shaking, sleep problems (insomnia), strange dreams, tired feeling, increased sweating, decreased sex drive, impotence, or difficulty having an orgasm.

Effexor XRĀ comes with aĀ black box warning on the prescription drug label that callsĀ attention to serious or life-threatening risks. In this case, the drug presents anĀ increased risk for suicidal thoughts and behaviors in people with major depression and other psychiatric disorders, especially during the first months of treatment or following changes in dosage.

A generic version of Effexor XR has been approved by the FDA but may notĀ be available because of patent or exclusivity issues.
