As with all medications, the cost of Boostrix can vary. Factors that may affect the price you’ll pay include:

  • your insurance coverage
  • the pharmacy you use
  • the cost of the visit to your healthcare professional to receive a dose of Boostrix
  • whether Boostrix has a savings program (see the “Financial and insurance assistance” section below)

To find out what the cost of Boostrix will be for you, talk with your doctor, pharmacist, or insurance provider.

Insurance considerations

Below is information you may want to consider if you have insurance and receive Boostrix.

Prior authorization. If you have insurance, your insurance company may require prior authorization before it covers Boostrix. This means the company and your doctor or pharmacist will discuss the importance of Boostrix for your health. The insurance company will then determine whether the cost of Boostrix is covered. If it requires prior authorization but you receive the vaccine without prior approval, you could pay the full cost. You can ask your insurance company whether Boostrix requires prior authorization.

Type of insurance coverage. Boostrix is given by your doctor, pharmacist, or another healthcare professional. If you have insurance, what you’ll pay for Boostrix may depend on your specific insurance plan and where you receive the vaccine. If you receive it at your doctor’s office, your doctor may bill the price through the medical coverage portion of your insurance plan. If you receive Boostrix at your pharmacy, they may bill the prescription drug portion of your insurance plan.

If you have questions about this process, contact your doctor, pharmacist, or insurance provider.

Here are answers to some frequently asked questions about drug cost and Boostrix.

* Tdap is short for tetanus, diphtheria, and pertussis, the diseases that Boostrix helps prevent.

Boostrix contains the active ingredients tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis. Boostrix is available only as a brand-name biologic drug and doesn’t come in a biosimilar version. A biosimilar medication is a drug that’s similar to a brand-name biologic drug (the parent drug). Also, biosimilars tend to cost less than brand-name medications.


Biologic drugs can be expensive because of the research needed to test their safety and effectiveness. The manufacturer of a biologic drug can sell it for up to 12 years. When the biologic drug’s patent expires, multiple manufacturers can create biosimilar versions. This marketplace competition may lead to lower costs for biosimilars. Also, because biosimilars are very similar to biologic drugs, they don’t require the same costly testing.

If you need financial support to pay for Boostrix, or if you need help understanding your insurance coverage, help is available. For example:

  • A program called GSK for You is available for Boostrix. For more information and to find out if you’re eligible for support, call 866-728-4368 or visit the program website.
  • Some websites provide details about drug assistance programs, ways to make the most of your insurance coverage, and links to savings cards and other services. NeedyMeds is one such website.
