Hello and welcome to Healthcare Magic. Thanks for your query.
Increasing the dose of your antidepressant Venlafaxine
from 75mg OD to 150mg BD is a drastic increase and may have adverse effects like increased anxiety
, agitation, drowsiness
, etc. I would advise you not to alter the doses of your medication without consulting a doctor. You can try some relaxation exercises and deep breathing for your anxiety and try to meet your doctor as early as possible.
Wish you all the best.
