Valdoxan (agomelatine) tablets are a prescription medication used primarily to treat major depressive disorder (MDD) in adults. Agomelatine, the active ingredient, is a melatonergic antidepressant that helps regulate the body’s circadian rhythms and improve mood by balancing neurotransmitters in the brain. It works by acting on melatonin and serotonin receptors, which can help alleviate symptoms of depression. Valdoxan is typically taken once daily, usually at bedtime, due to its effects on sleep patterns. Common side effects may include dizziness, nausea, and headache. It's important to follow the prescribed dosage and consult a healthcare provider for proper use and monitoring, as abrupt discontinuation can lead to withdrawal symptoms or worsening of depression.
