General & Family Physician 's  Response
Hello,

Tab. effexor contains venlafaxine whichever is a selective serotonin reuptake inhibitor and used as an antidepressant and anti-anxiety drug. It is not advisable to stop it suddenly as it causes severe withdrawal symptoms like a headache and irritability.

I would advise you to take him to his psychiatrist so that he can adjust his dose and also add some sedatives if required.

Hope I have answered your query. Let me know if I can assist you further.
