Hi doctor,

I have been prescribed with Valdoxan 25 mg for depression and anxiety. It has been four weeks. Still, I am feeling drowsy and difficulty in thinking straight and finding my words. Socially, I am feeling very anxious because I feel dumbed down. How long should I take this medication? Is the term of four weeks enough to see any beneficial effects?



Welcome to

  • Valdoxan (Agomelatin) is a melatonin agonist and a newer antidepressant drug.
  • The drug is used as an add-on drug for depression and also as monotherapy in mild to moderate depression. In most cases, the drug takes about four to six weeks to show its full effect.
  • You are on 25 mg dose since last four weeks and there is not much improvement. In such case, I would advise you to wait for a couple of weeks to see its full effect.
  • If symptoms persist beyond that period of time, then talk to your doctor and ask about dose adjustment.
