Hi, Well come to healthcaremagic, You have complain of iron deficiency & taking treatment for same as well as you have also constipation and on liq. Cremalax. This medicine will give you relief in constipation. But you are also complain of spot of blood while passing stool, for that I would like to say that if this type of patient come to my clinic I suggest them usually to go for endoscopy, colonoscopy as well as stool-R. & M. for proper diagnosis because you have already iron deficiency. Fiber contains diet, green vegetables & 2 glass of worm water will give very good result in your constipation. After done all reports don’t hesitate to share it on helthcaremagic, I will definitely like to give you answer again. Take care, Please give your review on healthcaremagic about my answer. Thank you.
