Since the exact composition of Colomie Forte can vary, it is not safe to suggest a direct substitute without knowing its ingredients or the reason it was prescribed along with Lizokef. In pilonidal sinus, doctors may prescribe antibiotics, probiotics, pain relief medicines, or digestive-support medicines depending on the infection and symptoms. Please check the strip composition or share a photo/name of the active ingredients for a proper alternative. Also, pilonidal sinus often requires surgical evaluation if there is recurrent pain, swelling, pus discharge, or fever.
