Can caffeine and antihistamines have an affect on Hair Transplant Graft survival and the final outcome?

I know both of these constrict blood vessels and blood supply so would this cause any harm (I am 16 days post op)? I have read that things like smoking and cocaine use can have negative effects due to their vasoconstriction so would these act the same? I like coffee a few times a day and usually take an antihistamine for allergies but if it will effect the outcome of the grafts surviving I am willing to do without coffee and deal with the allergies for a while.

At 16 days post-op your grafts are fairly well established so things like caffeine shouldn't really impact them. Even in the first few days they shouldn't have substantial impact.

Resuming habits after hair transplant

I am not aware of any study that shows caffeine or antihistaminies having any effect on transplanted hair. Of course avoiding medications or habits that result in vasoconstriction is always a good idea post operatively.  You are already more than 16 days out from surgery and the grafts are well seated and have re-established their vascular system.  You may resume all of your pre-hair transplant medications.
