What is effexor?
Venlafaxine is a type of medication classified as an antidepressant, prescribed for managing conditions such as major depressive disorder, social anxiety disorder, panic disorder, and generalized anxiety disorder. Belonging to the group of SNRIs (serotonin and norepinephrine reuptake inhibitors), effexor plays a role in sustaining and regulating mental well-being. In certain instances, it may also be utilized to alleviate hot flashes associated with menopause or in individuals undergoing breast cancer treatment.
What conditions can venlafaxine be used to treat?
Venlafaxine is prescribed by doctors to address various mental health conditions. It is commonly utilized to manage major depressive disorder, characterized by persistent feelings of sadness and disinterest in daily activities. Additionally, venlafaxine may be prescribed for panic disorder, an abrupt onset of intense fear leading to panic attacks even in the absence of real danger. It is also effective in treating generalized anxiety disorder, which involves prolonged feelings of unease and worry impacting daily functioning. In some instances, venlafaxine may be utilized to address social phobias triggered by anxiety in social situations.
What is the mechanism of action of venlafaxine?
Venlafaxine is classified as a selective serotonin and norepinephrine reuptake inhibitor (SNRI). Serotonin and norepinephrine are neurotransmitters that play a role in mood regulation and emotional well-being. These neurotransmitters are naturally produced by neurons in the brain and are involved in transmitting signals between neurons. After the signal transmission, the neurons reabsorb serotonin and norepinephrine for recycling purposes.
At times, neurons may reabsorb these hormones too quickly, preventing them from transmitting signals of happiness to the brain, leading to decreased levels of these chemicals that regulate mood. By reducing the reuptake of serotonin and norepinephrine in the brain, it is possible to stabilize mood and alleviate various conditions like stress, anxiety, and depression.
What are the most common side effects of venlafaxine?
Although there are some common side effects associated with effexor, it is important to remember that your doctor prescribed this medication because he believes its ability to improve your mental health outweighs any negative effects it may cause.

What is the typical duration for effexor to take effect?
Venlafaxine may require 6 to 8 weeks to fully impact your mood. It is advisable to continue your medication regimen even if you feel better. Consult your doctor before discontinuing venlafaxine, as abrupt cessation can lead to withdrawal symptoms.
What is the usual starting dose of venlafaxine?
The usual recommended starting dose of venlafaxine is 75 mg per day, divided into two or three doses, and should be taken with food. The tablet should be swallowed whole, without crushing, splitting or dissolving in water. Depending on how your body responds to venlafaxine, your doctor may gradually increase your dose.
