WHY is this medicine prescribed?
CollagenaseClostridium histolyticuminjection is used to treat Dupuytren's contracture (a painless thickening and tightening of tissue [cord] beneath the skin in the palm of the hand, which may make it difficult to straighten one or more fingers) when a cord of tissue can be felt upon examination. CollagenaseClostridium histolyticuminjection is also used to treat Peyronie's disease (a thickening of tissue [plaque] inside the penis that causes the penis to curve). CollagenaseClostridium histolyticuminjection is in a class of medications called enzymes. In people with Dupuytren's contracture, it works by helping to break down the cord of thickened tissue and allows the finger(s) to be straightened. In people with Peyronie's disease, it works by helping to break down the plaque of thickened tissue and allows the penis to be straightened.
HOW should this medicine be used?
CollagenaseClostridium histolyticuminjection comes as a powder to be mixed with a liquid and injected by a doctor. If you are receiving collagenaseClostridium histolyticumto treat Dupuytren's contracture, your doctor will inject the medicine into a cord just under the skin in the affected hand. If you are receiving collagenaseClostridium histolyticumto treat Peyronie's disease, your doctor will inject the medicine into the plaque that is causing your penis to curve. Your doctor will choose the best place to inject the medication in order to treat your condition.
If you are receiving treatment for Dupuytren's contracture, do not bend or straighten the fingers of the injected hand or put pressure on the injected area after your injection. Keep the injected hand elevated until bedtime. You must return to your doctor's office on the day after your injection. Your doctor will check your hand, and possibly move and extend the finger to help break up the cord. Ask your doctor when you can expect to see improvement, and call your doctor if your condition does not improve during the expected time. Your doctor may need to give you additional injections if your condition does not improve. Do not perform strenuous activity with the injected hand until your doctor tells you that you can do so. Your doctor will probably tell you to wear a splint every night (at bedtime) for up to 4 months after the injection. Your doctor may also tell you to do finger exercises each day. Follow the directions of your doctor carefully and ask the doctor to explain any part you do not understand.
If you are receiving treatment for Peyronie's disease, your doctor will inject collagenaseClostridium histolyticuminto your penis, followed by a second injection 1 to 3 days after the first injection You must return to your doctor's office 1 to 3 days after your second injection. Your doctor will gently move and stretch your penis (penile modeling procedure) to help straighten your penis. Your doctor will also tell you to gently stretch and straighten your penis at home for 6 weeks afterward. Follow the directions of your doctor carefully and ask the doctor to explain any part you do not understand. Avoid sexual activity for at least 2 weeks after your last injection and after pain and swelling have gone away. Your doctor may need to give you additional treatment cycles.
