Anal Fissure

Medically reviewed by Last updated on Feb 6, 2023.

An anal fissure is a cut or tear in the tissue inside your anus. An anal fissure may be acute or chronic. An acute anal fissure is usually small and shallow and often heals without treatment. A chronic fissure may last longer than a month and will usually require treatment. A chronic anal fissure comes back after treatment.



  • Topical medicine: Topical medicine may be put just inside your anus. This medicine may help your anal muscle relax and increase blood flow to your anus. This medicine may contain anesthesia to help decrease your pain. Your healthcare provider will teach you the right way to use topical medicine.
  • Stool softeners: Your healthcare provider may also give you medicine that makes your bowel movements softer. This helps prevent constipation. You will be less likely to strain and cause an anal fissure if you are not constipated.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider as directed:

Your healthcare provider will need to make sure your anal fissure heals. Write down your questions so you remember to ask them during your visits.


You may need to soak in a warm tub or take a sitz bath. This may help decrease pain and swelling. You may need to do this more than once a day. Ask your healthcare provider how to use a sitz bath and how often you should bathe.

Treatment options

The following list of medications are in some way related to or used in the treatment of this condition.

Bowel care:

Do not ignore the urge to have a bowel movement. Do not strain. Clean the area gently after every bowel movement.


Eat foods that are high in fiber to help keep your bowel movements soft. High-fiber foods include fruits, vegetables, and whole grains. Drink more liquids to help soften your bowel movements. This will help prevent you from straining. Ask your healthcare provider how much liquid you should drink each day.

Sexual intercourse:

Avoid anal intercourse for as long as directed by your healthcare provider. Anal intercourse may make it harder for your anal fissure to heal. It may also tear more tissue around your anus.

Contact your healthcare provider if:

  • You have a fever.
  • You still have pain after taking pain medicine.
  • You are unable to have a bowel movement.
  • You have spasms in your anus that do not stop.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • You have very bad pain in or around your anus.
  • You have bleeding from your anus that does not stop.
