Venlafaxine is an antidepressant medication used to treat depression and various anxiety disorders, including generalized anxiety disorder (GAD), social anxiety disorder, and panic disorder.

This medication belongs to the class of selective serotonin and norepinephrine reuptake inhibitors (SNRIs) and works by enhancing the levels of serotonin and norepinephrine, which are natural neurotransmitters that play a role in regulating mental stability.

Uses and Dosage

Follow your doctor’s instructions for taking this medication, typically once daily with food, either in the morning or evening.

Do not crush, chew, or dissolve the medication, as doing so can release all of the drug at once and increase the risk of side effects. Swallow the medication whole without crushing or chewing.

If you have difficulty swallowing capsules, you may open them and sprinkle the contents onto a spoonful of applesauce. Swallow the entire mixture immediately without chewing, followed by a glass of water.

The dosage is determined by your medical condition and response to treatment. To minimize side effects, your doctor may advise starting at a low dose and gradually increasing it. Adhere to your doctor’s instructions and take the medication regularly at the same time each day.

Continue taking this medication even if you feel well, and do not discontinue without consulting your doctor, as some conditions may worsen if the drug is abruptly stopped. Abrupt cessation may also cause symptoms such as confusion, mood swings, blurred vision, headache, tiredness, sleep changes, and brief sensations akin to electric shock. Your dose may need to be reduced gradually to mitigate side effects.

It may take several weeks to feel the effects of this medication. If your condition persists or worsens, notify your doctor.

Prior to using venlafaxine, inform your physician or pharmacist of any known allergies to the medication or its inactive ingredients. A comprehensive medical history must be shared, including any history of bleeding disorders, glaucoma, hypertension, cardiac issues, high cholesterol, kidney or liver disease, seizure disorders, and thyroid disorders.

During treatment with venlafaxine, individuals may experience dizziness, drowsiness, or blurred vision. Engaging in activities that require alertness or clear vision, such as driving or operating machinery, should be avoided.

Refrain from consuming alcoholic beverages. In case of marijuana use, consultation with a doctor is necessary.

Children may be more susceptible to adverse effects of the drug, particularly weight loss and loss of appetite, and therefore, it is crucial to monitor their weight and height.

During pregnancy, the use of venlafaxine should only be considered when the potential benefits outweigh the potential risks. The medication has the potential to harm an unborn child and newborns may rarely exhibit withdrawal symptoms such as feeding difficulties, seizures, muscle stiffness, and excessive crying. The medication is present in breast milk and may cause adverse effects in nursing infants, thus consultation with a doctor is necessary prior to breastfeeding.
