My father suffers from high blood pressure since he has step in his forties. He has been taking medication to maintain the level of his high blood pressure. It has been five months that he has started suffering from severe constipation. He thought that it may be due to all these medications he is taking. When he went to his doctor to check his blood pressure, he told him about his constipation problem but the latter told him that it will be ok. Seeing that he is constantly constipating, dad decided to find a solution himself. Dad knows about a medication called conthram which used in treatment of constipation and he wanted to more information on it. Will conthram interact with the laxatives he is taking??

If he is already taking laxatives, then why would he take something else to relieve his constipation?

exactly, id use one or the other
