Before Using Bayhep B

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines.

For non-prescription products, read the label or package ingredients carefully.

Geriatric

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of hepatitis B immune globulin in the elderly with use in other age groups.

Interactions with Medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur.

Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Interactions with Food/Tobacco/Alcohol

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

• Bleeding problems— Because hepatitis B immune globulin (human) is given as a shot into a muscle, it may cause more bleeding
