Fepace OD Tablet contains several components that can affect bowel movements differently. Carbonyl iron, a key ingredient, may sometimes cause constipation as a side effect, while docusate sodium is a stool softener that usually helps prevent constipation. The other ingredients like adenosylcobalamin (a form of vitamin B12), folic acid, and zinc sulfate generally do not cause constipation.

Given your condition with piles (hemorrhoids) and fissures, the presence of docusate sodium in the tablet is beneficial as it helps keep stools soft, reducing strain during bowel movements and easing symptoms. However, if you notice worsening constipation or discomfort, it is important to inform your doctor, who may adjust your treatment or suggest additional measures such as increased fiber intake and hydration.

If you want, I can explain how to manage piles and fissures alongside your medication. Meanwhile, please consult your prescribing doctor or a gastroenterologist for personalized advice and monitoring.
