Diosmin tablets are a drug used in both vascular surgery and anorectal medicine. It is a vasoactive drug whose mechanism of action is to promote the function of local venous blood vessel walls, enhance venous and lymphatic reflux and improve microcirculation. In the treatment of hemorrhoids, Diosmin tablets promote the reflux of the veins of the hemorrhoid body to achieve a certain degree of reduction of the hemorrhoid body. The shrinking of the hemorrhoid body has the effect of reducing internal hemorrhoid bleeding to a certain extent. Oral Diosmin tablets alone are limited in the treatment of hemorrhoids and often need to be combined with topical medications such as ointments, suppositories and sitz baths for anal use to achieve better results. The size of the hemorrhoid body and the severity of the hemorrhoid require an examination at a specialist hospital to determine the specific treatment plan, and you cannot rely on just one medication. The use of any medication should be regulated by the doctor’s advice after examination at a specialist hospital.
