Pharmacist-reviewed drug information from the RxWiki encyclopedia.

Overview

Pneumovax 23 is a vaccine that is given as a shot. It helps protect you from infection by certain germs or bacteria which are called pneumococcus and can cause pneumonia and meningitis.

Most often Penumovax 23 is just given as one shot and is injected into the muscle or under the skin by a healthcare provider. 

Common side effects are pain, warmth, soreness, redness, swelling, and hardening at the injection site. 

What is it used for?

Pneumovax 23 is a vaccine that is given as a shot to help protect you from pneumococcal disease caused by the 23 serotypes.

Pneumovax 23 is for people 50 years of age and older. It is also for people who are 2 years of age and older if they have certain medical conditions that put them at increased risk for infection.

How to take it

Most often Penumovax 23 is just given as one shot that is injected either into the muscle or just under the skin. 

Penumovax 23 is approved for use in persons 50 years of age or older and persons aged ≥2 years who are at increased risk for pneumococcal disease.

If you or your child is in a high-risk group for pneumococcal infection, then your health care provider will decide if it would be helpful to give a second shot of Pneumovax 23 at a later time.

Warnings

Tell your health care provider or get emergency help right away if you get any of the following problems after vaccination because these may be signs of an allergic reaction or other serious conditions:

  • difficulty breathing
  • wheezing
  • rash
  • hives

Pneumovax 23 may not protect everyone who gets it. It will not protect against diseases that are caused by bacteria types that are not in the vaccine.

Talk to your health care provider if you plan to get Zostavax at the same time as Pneumovax 23 because it may be better to get these vaccines at least 4 weeks apart.

You should not get this vaccine if you (or your child):

  • are allergic to any of its ingredients
  • had an allergic reaction to Pneumovax 23 in the past
  • are less than 2 years old

Side effects

The most common side effects include:

  • pain, warmth, soreness, redness, swelling, and hardening at the injection site
  • headache
  • weakness, feeling tired
  • muscle pain

Side effects at the site where you get the shot may be more common and may feel worse after a second shot than after the first shot.

Tell your health care provider if you or your child has a side effect that bothers you or that does not go away.

For a more complete list of side effects, ask your health care provider.

You may also report any side effect to your or your child's health care provider, or directly to the Vaccine Adverse Event Reporting System (VAERS). You may call the VAERS number 1-800-822-7967 at no charge, or report online to www.vaers.hhs.gov.

Drug interactions

Tell your doctor about all the medicines you take including prescription and nonprescription medicines, vitamins and herbal supplements. Especially tell your doctor if you are planning on getting Zostavax at the same time as Pneumovax 23. 

This is not a complete list of Pneumovax 23 drug interactions. Ask your doctor or pharmacist for more information. 

Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications and vaccines based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Pneumovax 23 falls into category C. There are no well-controlled studies that have been done in pregnant women. Pneumovax 23 should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby. 

Breastfeeding

Tell your doctor is you are breastfeeding or plan to breastfeed. 

It is not known if Pneumovax 23 crosses into human milk. Because some vaccines can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this vaccine, a choice should be made whether to stop nursing or stop the use of this vaccine. Your doctor and you will decide if the benefits outweigh the risk of using Pneumovax 23.
