SIDE EFFECTS: Pain, swelling, and redness at the injection site may occur. Drowsiness, irritability/crying, loss of appetite, or fever may also occur. If any of these effects persist or worsen, tell the health care professional promptly. Infrequently, temporary symptoms such as fainting/dizziness/lightheadedness, vision changes, numbness/tingling, or seizure-like movements have happened after vaccine injections. Tell your health care professional right away if your child has any of these symptoms soon after receiving an injection. Sitting or lying down may relieve symptoms. Remember that your health care professional has prescribed this vaccine because he or she has judged that the benefit to your child is greater than the risk of side effects. Many children receiving this vaccine do not have serious side effects. Get medical help right away if your child has any very serious side effects, including: seizures, unresponsiveness.

PRECAUTIONS: Before receiving this vaccination, tell your health care professional if your child is allergic to it; or to any other vaccines; or if your child has any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your health care professional for more details. Before receiving this vaccine, tell the health care professional your child's medical history, especially of: vaccination history, blood disorders (such as bleeding problems, low platelets), history of a certain nerve problem (Guillain-Barre syndrome), weakened immune system (such as due to cancer, HIV, leukemia, lymphoma, radiation treatment), premature birth.

DRUG INTERACTIONS: Drug interactions may change how your child's medications work or increase your child's risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products your child uses (including prescription/nonprescription drugs and herbal products) and share it with the health care professional. Do not start, stop, or change the dosage of any medicines without your child's doctor's approval. Some products that may interact with this vaccine include: "blood thinners" (such as warfarin, heparins), corticosteroids (such as hydrocortisone, prednisone), cancer chemotherapy, drugs that weaken the immune system (such as cyclosporine, tacrolimus). Other vaccines may be given at the same time as this vaccine, but should be given with separate syringes and at different injection sites. This vaccine may interfere with certain laboratory tests (including urine tests), possibly causing false test results. Make sure laboratory personnel and all the health care professionals know your child has recently been vaccinated.
