Indications
Cinchocaine Hydrochloride (also called Dibucaine) is a local anaesthetic, a medicine that numbs the skin or lining it is applied to. It is mainly used in ointments and suppositories for haemorrhoids (piles) and anal fissures (small tears near the back passage) to relieve pain, itching and burning. It is usually combined with a mild steroid such as Hydrocortisone or Prednisolone, which reduces swelling.
How It Works
Cinchocaine blocks sodium channels in nerve endings. This stops the nerves from sending pain and itch signals to the brain, so the area becomes numb for a few hours. It does not heal the piles itself; the steroid in combination products reduces inflammation.
Dosage and Administration
- Ointment: apply a small amount to the affected area 2 to 3 times a day and after each bowel movement, usually for no longer than 7 days unless your doctor advises otherwise.
- Suppository: insert one into the back passage 1 to 3 times a day, usually after a bowel movement, as directed on the label.
Wash and dry the area gently before use and wash your hands afterwards.
Interactions
Few interactions are expected with use on the skin. Avoid using other local anaesthetic products on the same area at the same time. Tell your doctor about all medicines you take, including Sulfonamide antibiotics, as some local anaesthetics may reduce their effect.
Contraindications
Do not use if you are allergic to Cinchocaine or other amide local anaesthetics such as Lidocaine. Combination products with a steroid should not be used on areas with untreated bacterial, viral (such as herpes) or fungal infection, or tuberculosis of the skin.
Side Effects
- Mild burning or stinging when first applied
- Itching, redness or skin irritation
- Allergic skin reaction (contact dermatitis)
- With long use of steroid combinations: thinning of the skin around the anus
Get urgent medical help if you have rectal bleeding that is heavy or does not stop, severe pain, swelling of the face or lips, difficulty breathing, or a fast or irregular heartbeat.
Pregnancy and Lactation
Short-term use on a small area is generally considered low risk, but use during pregnancy and breastfeeding only if a doctor advises it, especially in the first 3 months of pregnancy.
Precautions and Warnings
For external or rectal use only; do not swallow. Do not use for more than 7 days without medical advice. See a doctor if bleeding occurs, symptoms get worse, or you notice a change in bowel habit, as these can be signs of a more serious condition. Not usually recommended for children unless prescribed.
Overdose
Swallowing the product or using large amounts on broken skin can cause numbness of the mouth, dizziness, confusion, fits and heart rhythm problems. Seek emergency medical help immediately.
Therapeutic Class
Local anaesthetic (amide type), used in anorectal preparations.
Storage
Store below 30°C in a dry place, away from light and out of the reach of children. Suppositories may need to be kept below 25°C; follow the pack.
