Pharmacological Treatment of Hemorrhoids

First-Line Pharmacological Options

Flavonoids are recommended to relieve hemorrhoidal symptoms by improving venous tone, with evidence showing effectiveness for controlling acute bleeding in all grades of hemorrhoids 1
Topical analgesics, such as lidocaine, provide symptomatic relief of local pain and itching, though data supporting their long-term efficacy are limited 2
Topical corticosteroid creams may ameliorate local perianal inflammation but should be used for no more than 7 days to avoid thinning of perianal and anal mucosa 2
Topical muscle relaxants are suggested for thrombosed or strangulated hemorrhoids to provide relief from pain associated with anal sphincter hypertonicity 1

Topical nitrates have shown good results in relieving pain due to thrombosed external hemorrhoids, presumably by decreasing anal tone, though headaches may limit their use 2
Topical heparin treatment has been found to significantly improve healing and resolution of acute hemorrhoids, although evidence is limited due to small study sizes 3

For internal hemorrhoids, flavonoids can be used for bleeding control, and topical analgesics can be used for discomfort 1, 2
For external hemorrhoids, topical nifedipine with lidocaine can be used for pain relief, and short-term topical corticosteroids can be used for inflammation 2, 3
For thrombosed external hemorrhoids, topical muscle relaxants can be used for pain relief, and topical nitrates can be used if muscle relaxants are ineffective 1, 2

Increased dietary fiber and water intake should always accompany pharmacological treatment 3
Avoidance of straining during defecation is essential to prevent exacerbation of symptoms 3
Sitz baths can provide symptomatic relief and should be recommended alongside pharmacological options 3
For persistent symptoms despite pharmacological treatment, procedural interventions like rubber band ligation should be considered 2, 3
