Adacel

Print Friendly, PDF & Email

Generic Name: Pertussis Vaccine – Acellular Combined with Diphtheria and Tetanus Toxoids (Adsorbed)
Product Name: Adacel

Indication: What Adacel is used for

Adacel is a vaccine used to help prevent whooping cough (pertussis), tetanus, and diphtheria.

This vaccine is for use as a booster in persons from the age of 10 years who have previously received childhood immunisation.

Adacel is not intended for childhood immunisation.

The use of Adacel should be determined on the basis of official recommendations and by your doctor.

Whooping cough, tetanus and diphtheria cause significant sickness and sometimes death in unvaccinated infants, children, and adults.

Action: How Adacel works

Adacel works by causing the body to produce its own protection against whooping cough, tetanus, and diphtheria. It does this by making substances called antibodies in the blood, which fight the bacteria and toxins that cause these diseases. If a vaccinated person comes into contact with these bacteria and toxins, the body is usually ready to destroy them.

It usually takes several weeks after vaccination to develop protection against these diseases.

A course of whooping cough, tetanus and diphtheria vaccine is usually given during early childhood at 2, 4 and 6 months of age, followed by a booster at 4 years of age. In case of whooping cough, tetanus and diphtheria, a second booster is required at the age of 15-17 years.

Most people will produce enough antibodies against these diseases. However, as with all vaccines, 100% protection cannot be guaranteed.

The vaccine will not give you any of these diseases.

The chance of a severe reaction from Adacel is very small, but the risks of not being vaccinated against these diseases may be very serious.

Adacel contains the active ingredients 2.5 mcg pertussis toxoid, 5 mcg pertussis filamentous haemagglutinin, 5 mcg pertussis fimbriae types 2 and 3, 3 mcg pertussis pertactin, 2 or more IU diphtheria toxoid, and 20 or more IU tetanus toxoid. It also contains other ingredients aluminium phosphate, Phenoxyethanol, formaldehyde, glutaraldehyde, and water for injections.

The manufacture of this product includes exposure to bovine materials. No evidence exists that any case of vCJD (considered to be the human form of bovine spongiform encephalopathy) has resulted from the administration of any vaccine product.

Dose advice: How to use Adacel

Before you are given it

Tell your doctor if you have reacted to previous vaccination with any of the following:

  • Life-threatening allergic reaction;
  • Fainting or collapse;
  • Shock-like state or being unresponsive for a long period of time;
  • Fits or convulsions;

Tell your doctor if you have not previously received the complete course of tetanus and diphtheria vaccination.

Tell your doctor if you have an infection or high temperature. Your doctor may decide to delay vaccination until the illness has passed. A mild illness, such as a cold, is not usually a reason to delay vaccination.

Tell your doctor if you have, or have had, any medical conditions, especially the following:

  • Lowered immunity due to diseases such as some blood disorders, malaria, kidney disease requiring dialysis, HIV/AIDS or cancer;
  • Lowered immunity due to treatment with medicines such as corticosteroids, cyclosporin or other medicines used to treat cancer (including radiation therapy);
  • Leukaemia or any other cancers of the blood, bone marrow or lymph system;
  • Brain disease;
  • Epilepsy;
  • Fits or convulsions;
  • Severe allergic reactions;
  • A low blood platelet count.

Tell your doctor if you have allergies to:

  • Any vaccines;
  • Any other medicines;
  • Any other substances, such as foods, preservatives or dyes.

Tell your doctor if you are pregnant or intend to become pregnant. Your doctor will discuss the possible risk and benefits of having Adacel during pregnancy.

Tell your doctor if you are breastfeeding. Your doctor will discuss the possible risks and benefits of having Adacel during breastfeeding.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.

Having other vaccines

Your doctor will advise you if Adacel is to be given with another vaccine.

How Adacel is given

Adacel is given as an injection, usually into your upper arm muscle by a doctor or nurse.

For some people with bleeding problems, Adacel may need to be given under the skin.

Adacel should not be injected directly into the veins.

How much is given

The dose of Adacel is a single dose of 0.5 mL.

When it is given

Adacel is generally given whenever a booster dose of whooping cough, tetanus and diphtheria vaccine is required.

After using Adacel

Storage

Adacel is usually stored in the doctor’s surgery or clinic, or at the pharmacy. However, if you need to store Adacel:

  • Keep it where children cannot reach it;
  • Keep Adacel in the original pack until it is time for it to be given;
  • Keep it in the refrigerator, between 2°C and 8°C. Do not freeze Adacel. Freezing destroys the vaccine.

Do not use Adacel after the expiry date printed on the pack. Do not use Adacel if the packaging is torn or shows signs of tampering.

Schedule of Adacel

Adacel is an S4 – prescription only medicine.

Side effects of Adacel

All medicines, including vaccines, can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
