Venlafaxine is a medication primarily used to treat major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. It belongs to a class of medications known as serotonin-norepinephrine reuptake inhibitors (SNRIs). Venlafaxine works by increasing the levels of serotonin and norepinephrine in the brain, which are neurotransmitters involved in regulating mood and anxiety.

Dosage: The dosage of venlafaxine varies depending on the condition being treated. It's typically started at a low dose and gradually increased as tolerated.

Form: Venlafaxine is available in immediate-release tablets, extended-release capsules, and oral suspension.

Timing: It is usually taken once daily with food to help minimize gastrointestinal side effects.

Follow Instructions: Always follow the instructions provided by your healthcare provider or pharmacist.

Avoid Abrupt Discontinuation: It's important not to suddenly stop taking venlafaxine, as it can cause withdrawal symptoms. Gradual tapering under medical supervision is recommended.

Common Side Effects: Nausea, headache, dizziness, insomnia, dry mouth, sweating, and constipation are common side effects.

Serious Side Effects: These can include increased blood pressure, suicidal thoughts or behaviors, serotonin syndrome (a potentially life-threatening condition characterized by agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea), and withdrawal symptoms if stopped abruptly.

Allergic Reactions: Seek immediate medical attention if you experience symptoms of an allergic reaction, such as rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing.

Pregnancy and Breastfeeding: Venlafaxine should be used with caution during pregnancy and breastfeeding, as it may harm the fetus or nursing infant.

Interactions: It's important to inform your healthcare provider about all medications you are taking, including over-the-counter drugs and supplements, as venlafaxine can interact with certain medications.

Medical Conditions: Inform your doctor if you have a history of certain medical conditions, such as heart disease, high blood pressure, seizures, bleeding disorders, or liver or kidney problems, as venlafaxine may not be suitable or may require dosage adjustments in these cases.
