10 to 15 minutes several times daily
Topical anesthetic short course
Lidocaine 2 percent topical per label
Avoid prolonged use due to irritation risk
Oral analgesia
Acetaminophen 10 mg per kg to 15 mg per kg every 4 to 6 hours as needed

Gentle cleansing
Water rinse or nonfragranced wipes
Barrier protection
Zinc oxide paste thin layer
Avoid irritants
Fragranced soaps
Excess wiping
Office-based procedures
Minimally invasive options for persistent symptoms
Rubber band ligation for internal hemorrhoids
Strong recommendation moderate-quality evidence
Preferred office procedure in many patients
Sclerotherapy
Option when banding not feasible
Infrared coagulation
Option for bleeding predominant disease
Thrombosed external hemorrhoid
Time-sensitive pain strategy
If presentation within 72 hours and severe pain, excision or thrombectomy consideration
Local anesthesia approach in appropriate setting
Faster pain relief versus conservative management
If presentation beyond 72 hours, conservative management often preferred
Natural improvement expected
Avoid unnecessary incision when improving
Supportive regimen
Stool softening and fiber
Prevent recurrent strain
Analgesia
Acetaminophen dosing as above
Avoid NSAIDs if significant bleeding risk
Operative and advanced procedures
Surgical referral indications
Refractory grade III or grade IV internal hemorrhoids

Special Populations
Pregnancy
Pregnancy considerations
Increased risk in late pregnancy and postpartum
Pelvic venous congestion and constipation
Conservative measures prioritized
