Prevnar Dosage

Generic name: pneumococcal 7-valent vaccine
Dosage form: injection, suspension

The information at Drugs.com is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.

For intramuscular injection only. Do not inject intravenously.

The dose is 0.5 mL to be given intramuscularly.

Since this product is a suspension containing an adjuvant, shake vigorously immediately prior to use to obtain a uniform suspension in the vaccine container. The vaccine should not be used if it cannot be resuspended.

After shaking, the vaccine is a homogeneous, white suspension.

The vaccine is not to be mixed with other vaccines/products in the same syringe.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration (see DESCRIPTION). This product should not be used if particulate matter or discoloration is found.

The vaccine should be injected intramuscularly. The preferred sites are the anterolateral aspect of the thigh in infants or the deltoid muscle of the upper arm in toddlers and young children. The vaccine should not be injected in the gluteal area or areas where there may be a major nerve trunk and/or blood vessel. Before injection, the skin at the injection site should be cleansed and prepared with a suitable germicide. After insertion of the needle, aspirate and wait to see if any blood appears in the syringe, which will help avoid inadvertent injection into a blood vessel. If blood appears, withdraw the needle and prepare for a new injection at another site.
