Patient Medication Information: uses, side effects, how to take - Quadracel (Sanofi Vaccines Canada, 15 Lf / 5 Lf / 20 mcg / 20 mcg / 3 mc...)
What QUADRACEL® is used for:
QUADRACEL® is a vaccine that is used to help prevent against diphtheria, tetanus (lock jaw), pertussis (whooping cough) and polio. This vaccine may be given to children aged 2 months or older. It may also be given as a booster to children up to age 7.
The majority of children who are vaccinated with QUADRACEL® will produce enough antibodies to help protect them against these 4 diseases. However, as with all vaccines, 100% protection cannot be guaranteed.
How QUADRACEL® works:
QUADRACEL® causes the body to produce its own natural protection against diphtheria, tetanus, pertussis (whooping cough) and poliomyelitis. After your child receives the vaccine, the body begins to make substances called antibodies. Antibodies help the body to fight disease. If a vaccinated person comes into contact with one of the germs that cause these diseases, the body is usually ready to destroy it.
The ingredients in QUADRACEL® are:
Medicinal ingredients: Each 0.5 mL dose of QUADRACEL® contains: diphtheria toxoid, tetanus toxoid, acellular pertussis vaccine (pertussis toxoid, filamentous haemagglutinin, pertactin, fimbriae types 2 and 3) and inactivatedpoliovirus.
Non-medicinal ingredients: Aluminum phosphate (adjuvant), 2-phenoxyethanol, polysorbate 80, water for injection. Residual formaldehyde, glutaraldehyde, bovine serum albumin, neomycin, and polymyxin B sulphate and streptomycin sulphate may be present in trace amounts.
QUADRACEL® comes in the following dosage forms:
QUADRACEL® is a liquid vaccine that is injected into a muscle. A single dose is 0.5 mL.

Do not use QUADRACEL® if:
- Do not give QUADRACEL® to a child who has an allergy to any ingredient in the vaccine or has had an allergic reaction after receiving a vaccine that contained similar ingredients.
- Do not give QUADRACEL® to a person who has had a serious nervous system disorder within 7 days after a previous pertussis vaccine. In case of progressive nervous system disorder or uncontrolled epilepsy, vaccination may be considered only after a treatment has been established and the condition is stabilized.
To help avoid side effects and ensure proper use, talk to your healthcare professional
if your child has any of the following conditions BEFORE the child receives QUADRACEL® .
Talk about any health conditions or problems the child may have, including:
- A high fever or serious illness. Wait until the child is better to give the vaccination.
- An allergy to any component of the vaccine or the container.
- A serious nervous system adverse event following a previous pertussis vaccination.
- Diseases of the immune system or taking a medical treatment that affects the immune system. The vaccine may provide your child with a lower level of protection than it does for people with healthy immune systems. If possible, try to postpone the vaccination until after your child has completed the treatment.
- A bleeding disorder or taking blood-thinning medications. Tell the person giving the injection about your child’s condition. The injection must be done carefully to prevent excessive bleeding.
- A higher risk of seizure than the general population. A fever-reducing medication may be given to your child.
- Fainting can occur following, or even before, any needle injection. Therefore, tell your doctor or nurse if your child fainted with a previous injection.
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
DO NOT mix QUADRACEL® with other vaccines or medicinal products in the same syringe.
QUADRACEL® may be given at the same time but at separate sites with Hepatitis B vaccine, 7-valent pneumococcal conjugate vaccine, MMR and Varicella vaccines.
How to take QUADRACEL®:
Usual dose:
A single dose of 0.5 mL is recommended for routine immunization of infants at 2, 4, 6 and 18 months of age and in children up to their 7th birthday.
The vaccination should be given in the muscle, preferably in the thigh for children up to 1 year-old. In children >1 year of age, the shoulder is the preferred site since use of the thigh results in limping due to muscle pain.

For the preparation of PENTACEL® only:
QUADRACEL® is used as the liquid component to reconstitute lyophilized Act-HIB® [Haeomophilus b Conjugate Vaccine with Tetanus Protein-Conjugate]. Do not inject QUADRACEL® alone when protection against Haemophilus influenzae type b is also required.
Overdose:
If you think you, or a person you are caring for, have taken too much QUADRACEL®, contact a healthcare professional, hospital emergency department, or regional poison control centre or Health Canada’s toll-free number , 1-844-POISON-X (1-844-764-7669) immediately, even if there are no signs or symptoms.
Missed Dose:
If immunization is delayed for any reason, the recommended schedule is:
- 3 single doses of 0.5 mL with 2 months between doses
- a 4th dose given 6 to 12 months after the 3rd dose
Possible side effects from using QUADRACEL®:
These are not all the possible side effects your child may experience when receiving QUADRACEL®. If your child experiences any side effects not listed here, tell your healthcare professional.

Other common reactions include fever, increased crying, fussiness, being less active and have decreased eating. These side effects are usually mild and last no more than 3 to 4 days. Severe reactions, such as high fever, swelling and redness of the entire arm or leg, or a serious allergic reaction are very rare.
Tell your doctor, nurse or pharmacist as soon as possible if your child is not feeling well after receiving QUADRACEL®.
