Before taking Mononine, tell your doctor about all of your medical conditions. Especially tell your doctor if you:

  • are pregnant or breastfeeding

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements.

Mononine and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X - are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Mononine falls into category C. No studies have been done in animals, and there are no well-done studies in pregnant women. Mononine should be given to a pregnant woman only if clearly needed.

Mononine and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known whether Mononine crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Mononine.

Mononine Usage

Take Mononine exactly as prescribed.

Mononine is given directly into the bloodstream. Mononine should be administered as ordered by your healthcare provider. You should be trained on how to do infusions by your healthcare provider or hemophilia treatment center. Many people with hemophilia B learn to infuse their Mononine by themselves or with the help of a family member.

You may have to have blood tests done after getting Mononine to be sure that your blood level of factor IX is high enough to clot your blood. Call your healthcare provider right away if your bleeding does not stop after taking Mononine.

If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take 2 doses of Mononine at the same time.

Mononine Dosage

Take Mononine exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

Your healthcare provider will tell you how much Mononine to use based on your weight, the severity of the factor IX deficiency, the location and extent of bleeding, your clinical condition, age, and recovery of factor IX.

Mononine Overdose

If you take too much Mononine call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

If Mononine is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.
