What is the most important information I should know about hemin?


What is hemin?

Hemin is made of red blood cells processed from human blood. Hemin works by lowering the production of a certain enzyme in the body.

Hemin is used to treat the symptoms of occasional attacks of porphyria related to the menstrual cycle in women. Hemin helps control symptoms such as pain, increased heart rate or blood pressure, and changes in mental status.

Hemin should not be used to treat porphyria that affects the skin, also called porphyria cutanea tarda.

Hemin is not a cure for porphyria. It will only control the symptoms of a porphyria episode.

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

What should I discuss with my health care provider before using hemin?

Hemin is usually given after other medicines to treat porphyria have been given for a certain amount of time.


Using too much hemin could harm your kidneys.


For best results, start using hemin at the first sign of a porphyria attack.

You may need to use hemin once or twice per day for up to 2 weeks, depending on how your body responds to the medicine.

After mixing the powder with the diluent, shake the mixture for 2 to 3 minutes.

Give the injection right away after mixing. Do not save it for later use. Throw away any unused mixture after one use. The hemin and diluent mixture does not contain a preservative.
