Anal Fissure Medical Treatment

• Diet and stool softening+−

  Tap for details

  Daily fiber and plenty of water are foundational. Psyllium or prescribed softeners are added when needed. Aim for soft, formed stool without straining. Excess diarrhea also irritates the tear — balance matters.

  • Fiber + fluids
  • Softeners when needed
  • No straining · short toilet time
  • Regular meals and walking
• Warm sitz baths+−

  Tap for details

  Two to three times daily for 10–15 minutes in warm (not scalding) water. Baths ease spasm, help hygiene, and calm pain — especially after stooling. Pat dry gently; avoid perfume, alcohol wipes, and scrubbing. Baths complement cream; they do not replace it.

• Nitroglycerin (NTG) ointment+−

  Tap for details

  Low-dose topical NTG (often around 0.2%) relaxes the internal sphincter via nitric oxide and improves blood flow to the tear. Healing rates in series are often roughly 50–70%. Headache is the most common side effect; dose change or another cream may be needed. Pregnancy and some heart medicines require clinician clearance.

• Diltiazem cream+−

  Tap for details

  Topical diltiazem (commonly 2% formulations) also relaxes sphincter tone. Healing is in a similar band to NTG; headache is usually less. Many centers use it first-line or as an NTG alternative. Regular application matters.

• If medical care fails+−

  Chronic or resistant fissures move to Botox and, when needed, LIS — already covered in dedicated chapters. Soft-stool habits continue even after procedures to cut recurrence.
