There are several factors that may affect your dosage of muromonab-CD3, including your age, weight (in children), and how you respond to the drug. This medicine comes as an injection that is administered intravenously by a healthcare provider. You may receive other medications in combination with muromonab-CD3 to help avoid potentially serious side effects.
An Introduction to Your Dosage of Muromonab-CD3The dose of muromonab-CD3 (Orthoclone OKT®3) your healthcare provider recommends will vary, depending on a number of factors, including:
- Your age
- Weight (in children)
- Levels of the medication in your blood
- How you respond to the medication.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Muromonab-CD3 Dosing GuidelinesThe usual dose of muromonab-CD3 for the treatment of transplant rejection in adults is 5 mg a day for 10 to 14 days. The usual initial dosage for children who weigh 30 kg or less (66 pounds or less) is 2.5 mg per day. Children who weigh more than 30 kg are normally given the adult amount.
Doses may be increased, usually by 2.5 mg a day, based on response and muromonab-CD3 blood levels. It is generally recommended that blood levels be at least 800 nanograms per milliliter (ng per mL), especially in children.
Your healthcare provider may give you a corticosteroid medicine, such as methylprednisolone (Depo-Medrol®, Medrol®), one to four hours before your first muromonab-CD3 dose. You may also be given acetaminophen (Tylenol®) and an antihistamine, such as diphenhydramine (Benadryl® and others), with each dose. These medications are used to reduce your risk of developing a potentially serious reaction to muromonab-CD3.
In addition, your healthcare provider may monitor your weight and obtain certain tests, such as an x-ray and blood tests, before you begin treatment. These tests are done to make sure you do not have certain medical problems that could increase your risk for complications.
