Effexor (venlafaxine) is an antidepressant and anxiolytic medication that belongs to the class of drugs known as serotonin-norepinephrine reuptake inhibitors (SNRIs). Withdrawal symptoms from Effexor can vary significantly from person to person and depend on several factors, including the dosage, the duration of use, and individual differences in metabolism and sensitivity to the medication.
Withdrawal symptoms can include dizziness, nausea, headache, fatigue, irritability, vivid dreams, brain zaps (brief electric shock-like sensations in the head), and mood changes, among others. These symptoms may occur when the medication is abruptly discontinued or if the dosage is rapidly decreased.
In most cases, Effexor withdrawal symptoms are expected to be at their worst within the first week after discontinuation and may gradually improve over the following weeks. However, for some individuals, withdrawal symptoms can persist for a more extended period, potentially lasting several weeks or even months.
If you are experiencing withdrawal symptoms or any concerning side effects after discontinuing Effexor, it's essential to consult with a healthcare professional. They can provide you with personalized advice, support, and possibly recommend a tapering schedule to help manage withdrawal symptoms more effectively.
