BayHep B Neonatal intramuscular Warnings

This medication may rarely cause serious blood clots (such as pulmonary embolism, stroke, heart attack, deep vein thrombosis). You may be at increased risk for blood clots if you are an older adult, are severely dehydrated, have a catheter in a vein close to your heart for administering medications, or have a history of blood clots, heart/blood vessel disease, heart failure, stroke, or if you are immobile (such as very long plane flights or bedridden). If you use estrogen-containing products, these may also increase your risk. Before using this medication, discuss the risks and benefits and if you have any of these conditions, report them to your doctor or pharmacist.

Being adequately hydrated before and after receiving this medication may help reduce your risk of blood clots. If you are receiving this medication into a vein, the risk may also be decreased by infusing this medication more slowly or by using a less concentrated form of this medication if available.

Get medical help right away if any of these side effects occur: shortness of breath/rapid breathing, chest/jaw/left arm pain, unusual sweating, sudden dizziness/fainting, pain/swelling/warmth in the arm/leg, sudden/severe headache, slurred speech, weakness on one side of the body, sudden vision changes, or confusion.

BayHep B Neonatal intramuscular Uses

This medication is used to prevent a certain serious virus infection (hepatitis B) in people who have been exposed to this virus under certain conditions (such as direct contact with blood or body fluids containing this virus). Certain brands of this medication may also be given after a liver transplant to prevent return of hepatitis B infection in people with previous infection. Ask your doctor or pharmacist if you have questions about your particular brand. This medication is made from healthy human blood that has high levels of certain defensive substances (antibodies) that help fight hepatitis B.

How to use BayHep B Neonatal intramuscular

If this medication is given for prevention of hepatitis B after direct exposure to the virus, it is given by injection into a muscle by a healthcare professional. It is best to receive this medication as soon as possible after exposure. If you wait too long after being exposed, the medication may not be effective. Your doctor may also recommend vaccination after receiving this medication. Talk with your doctor about the best treatment for you.

If this medication is given after a liver transplant to prevent return of hepatitis B infection, it is given by injection into a vein by a healthcare professional. For this use, it should be given on a regular schedule. To help you remember, mark your calendar with an appointment reminder.

The dosage and schedule of injections is based on your medical condition, weight, and response to treatment.

BayHep B Neonatal intramuscular Precautions

See also Warning section.

Before receiving hepatitis B immune globulin, tell your doctor or pharmacist if you are allergic to it; or to other immune globulin products; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: bleeding/blood clotting problems, a certain immune system problem (immunoglobulin A deficiency).

This drug may make you dizzy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.

This medication is made from human blood. Even though the blood is carefully tested, and this medication goes through a special manufacturing process, there is an extremely small chance that you may get infections (such as hepatitis A) from the medication. Consult your doctor or pharmacist for more information.

Some immune globulin products are made with maltose. This substance can cause false high blood sugar levels when your blood sugar is normal or even low. If you have diabetes, check with your doctor or pharmacist whether the product you are using contains maltose and whether your blood sugar testing supplies will work with this product. Rarely, serious problems have occurred when too much insulin was given because of false high sugar readings or when low blood sugar went untreated.

Tell your doctor of any recent or planned immunizations/vaccinations. This medication may prevent a good response to certain live viral vaccines (such as measles, mumps, rubella, varicella). If you have recently received any of these vaccines, your doctor may have you tested for a response or have you vaccinated again later. If you plan on getting any of these vaccines, your doctor will instruct you about the best time to receive them so you get a good response.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.

It is not known whether this drug passes into breast milk. Consult your doctor before breast-feeding.
