Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed. Take desvenlafaxine with water at the same time each day, with or without food. Swallow the tablet whole and do not crush, chew, or break it. Your symptoms may not improve for several weeks. Your blood pressure will need to be checked often. Tell your doctor if you have any changes in sexual function, such as loss of interest in sex, trouble having an orgasm, or (in men) problems with erections or ejaculation. Some sexual problems can be treated. Do not stop using desvenlafaxine suddenly, or you could have unpleasant symptoms (such as agitation, confusion, tingling or electric shock feelings). Ask your doctor before stopping the medicine. Part of a tablet shell may appear in your stool but this will not make the medicine less effective. Store at room temperature away from moisture and heat.

You should not use desvenlafaxine if you are allergic to desvenlafaxine or venlafaxine (Effexor). Do not use desvenlafaxine within 7 days before or 14 days after you have used an MAO inhibitor, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, or tranylcypromine. A dangerous drug interaction could occur. Tell your doctor if you also use stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with desvenlafaxine could cause a serious condition called serotonin syndrome.
