A member asked:
My brother takes effexor (venlafaxine) but thinks he has some stomach absorption problems. could we test this hypothesis, say through a blood test?
A doctor has provided 1 answer
No Effexor (venlafaxine) test: There is no test to see if specifically Effexor (venlafaxine) is not being absorbed properly but if he truly has absorption problems- as in calorie, fat, vitamins, protein, carbohydrates-there would be various other symptoms and signs-too numerous to go into here, but these do have various tests. There does not exist a blood test to test for drug malabsorption.
