My brother has been taking Hydralazine 100mg TID for the past year. He is mentally challenged so it is difficult to address any side effects other than visual occurrences. I have noticed large red bumps all over his arms and he scratches until he bleeds. He also has not been eating all his meals like he is accustom to doing. He started throwing up mostly in the early morning hours recently. I was wondering if this could be the Hydralazine. Thanks Janet
