Chymotrypsin is an enzyme. An enzyme is a substance that speeds up certain chemical reactions in the body. People use chymotrypsin to make medicine.
People take chymotrypsin by mouth or as a shot to reduce redness and swelling associated with pockets of infection (abscesses), ulcers, surgery, or traumatic injuries; and to help loosen phlegm in asthma, bronchitis, lung diseases, and sinus infections.
Chymotrypsin is sometimes breathed in (inhaled) or applied to the skin (used topically) for conditions that involve pain and swelling (inflammation) and for infections.
During cataract surgery, chymotrypsin is sometimes used to reduce damage to the eye.
- Cataract surgery, when used by a healthcare professional.
Possibly Effective for...
- Burns. There is some evidence that chymotrypsin might decrease tissue destruction in burn patients.
- Hand Fractures. Taking chymotrypsin by mouth seems to be effective for reducing redness and swelling associated with hand fractures.
Insufficient Evidence to Rate Effectiveness for...
Chymotrypsin has ingredients that reduce swelling (inflammation) and tissue destruction.
Chymotrypsin is safe when used in the eye by a healthcare professional. Chymotrypsin can cause side effects when used in the eye, including an increase in pressure in the eye and other eye conditions such as uveitis, paralysis of the iris, and keratitis.
It also seems to be safe for most people when taken by mouth to reduce redness and swelling following surgery or injury, and when applied directly to the skin for burns.
Not enough is known about the safety of chymotrypsin for its other uses.
Special Precautions & Warnings:Pregnancy and breast-feeding: Not enough is known about the use of chymotrypsin during pregnancy and breast-feeding. Stay on the safe side and avoid use.
The following doses have been studied in scientific research:
- To reduce tissue damage in burn patients: a 6:1 ratio (trypsin:chymotrypsin), in a combined amount of 200,000 units USP four times daily for ten days.
- Healthcare providers inject a solution of chymotrypsin into the eyes as part of cataract surgery.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
