Tranexamic acid prevents enzymes in the body from breaking down blood clots.

Cyklokapron is used to prevent bleeding in people with hemophilia who need to have a tooth pulled. This medication is usually given just before the dental procedure, and daily for up to 8 days afterward.

Tranexamic acid may also be used for purposes not listed in this medication guide.

You should not use Cyklokapron if you are color blind, if you have problems with the blood vessels in your eyes, or if you have ever had a stroke, blood clot, or bleeding in your brain.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Cyklokapron is given as an infusion into a vein just before your tooth is pulled. You may need to keep using this medicine for up to 8 days afterward.

A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
