Norezor (Venlafaxine)

Venlafaxine, the active ingredient in Norezor, is a serotonin‑norepinephrine reuptake inhibitor presented as a tablet for oral use. It is prescribed for major depressive disorder and several anxiety‑related conditions in adults. GNH USA supplies Norezor as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Venlafaxine acts on the serotonin and norepinephrine pathways and is used for several mood and anxiety disorders. - Major depressive disorder: alleviates depressive symptoms and improves mood. - Generalized anxiety disorder: reduces excessive worry and physical tension. - Social anxiety disorder: helps decrease fear of social situations. - Panic disorder: lowers frequency and intensity of panic attacks.

Venlafaxine may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Dry mouth: reduced salivation. - Headache: transient cranial pain. - Insomnia: difficulty falling or staying asleep. - Dizziness: light‑headed sensation. - Sweating: increased perspiration.

Serious or Rare Side Effects: - Hypertension: elevated blood pressure requiring monitoring. - Serotonin syndrome: potentially life‑threatening condition with agitation, hyperthermia, and neuromuscular abnormalities. - Suicidal thoughts: emergence of suicidal ideation, especially in young adults. - Liver injury: signs of hepatic dysfunction. - Severe allergic reaction: rash, swelling, or breathing difficulty. - Cardiac arrhythmia: irregular heart rhythm.

Before initiating Venlafaxine therapy, certain safety considerations are recommended. - Cardiovascular assessment: monitor blood pressure and heart rate regularly. - Psychiatric monitoring: watch for worsening depression or emergence of suicidal thoughts. - Liver function: evaluate hepatic enzymes in patients with liver disease. - Drug discontinuation: taper dose gradually to avoid withdrawal symptoms. - Pregnancy and lactation: discuss risks with a healthcare professional before use. - Store at ambient temperature: keep below 25 °C in the original container, protect from moisture and direct sunlight.

Venlafaxine can interact with several medication classes, influencing efficacy or safety.

Major Interactions (Avoid): - Monoamine oxidase inhibitors (MAOIs): risk of serotonin syndrome. - Tricyclic antidepressants: additive cardiovascular effects. - Certain antiarrhythmics: may increase plasma levels of venlafaxine.

Moderate Interactions (Monitor Closely): - NSAIDs or anticoagulants: heightened bleeding risk. - CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may raise venlafaxine concentrations. - Serotonergic agents (e.g., triptans, tramadol): monitor for serotonin syndrome signs.
