I have been prescribed COLESTYRAMINE (QUESTRAN LIGHT) for Bile Acid Mall Absorption (BAM) but I am allergic to the ingredient: Aspartame as it gives me chronic migraines. There is another medication called COLESTIPOL but one of the side effects is headache/migraine. Also there is another newer, more easily tolerated medication called : COLESEVELAM but I don't think it is licensed here in the UK. Is there anybody who is taking either Colestipol or Colesevelam who are able to help me as I don't know anybody else who takes this medication. I would be really interested to know how well these medications are tollerated and how you got on with them. Hope somebody is able to help. Many thanks.
