You are welcome,
Your husband is having lower GI tract bleeding (hematochezia
) which is most likely due to hemorrhoid
and given his age, anorectal polyps, tumors and fissures could also be incriminated as differential diagnosis. Mucinex
(which is an antituissive ) according to the manufacturers does not cause GI bleeding. You need to visit a surgeon for review and a colonoscopic examination will be indicated so as to get the proper diagnosis.
Antihemorrhoidal suppository or oral drugs would be indicated if you are having pile.
Hope you visit a surgeon soon
Best regards and merry x-mas
