1. What is Twinrix Adult and what is it used for
Twinrix Adult is a vaccine used in adults and adolescents from 16 years of age to prevent two diseases: hepatitis A and hepatitis B. The vaccine works by making the body produce its own protection (antibodies) against these diseases.
- Hepatitis A: Hepatitis A is an infectious disease that can affect the liver. This disease is caused by the hepatitis A virus. Hepatitis A can be transmitted from person to person through food and drink, or by swimming in waters contaminated with sewage. The symptoms of hepatitis A start 3 to 6 weeks after contact with the virus. These consist of nausea (discomfort), fever, and pain. After several days, the whites of the eyes and skin may turn yellow (jaundice). The severity and type of symptoms can vary. Young children may not develop jaundice. Most people recover completely, but the disease is usually severe enough for patients to be ill for about a month.
- Hepatitis B: Hepatitis B is caused by the hepatitis B virus. It causes liver inflammation. The virus is found in bodily fluids such as blood, semen, vaginal secretions, or saliva (sputum) of infected people.
Vaccination is the best way to protect against these diseases. None of the vaccine components are infectious.
2. What you need to know before you receive Twinrix Adult
Twinrix Adult must not be administered if:
- you are allergic to:
- the active substances or any of the other components of this vaccine (listed in section 6)
- neomycin.
Signs of an allergic reaction may include skin rash with itching, difficulty breathing, and swelling of the face or tongue.
- you have previously had an allergic reaction to any vaccine against hepatitis A and hepatitis B
- you have a severe infection with fever (over 38°C). A minor infection, such as a cold, should not be a problem for vaccination, but tell your doctor first.
Warnings and precautions
Talk to your doctor or pharmacist before receiving Twinrix Adult if:
- you have had any health problems after receiving a vaccine in the past
- you have a weakened immune system due to a disease or medication
- you have any bleeding problems or bruise easily.
Before or after any injection, fainting (especially in adolescents) may occur, so you should inform your doctor or nurse if you have fainted after receiving an injection in the past.
In obese people, a low response to the vaccine has been observed, possibly without achieving protection against hepatitis A. A low response to the vaccine, possibly without achieving protection against hepatitis B, has also been observed in elderly subjects, in men more than in women, in smokers, in obese people, and in people with chronic diseases, or those receiving some type of medication. Your doctor may recommend that you have a blood test after completing the vaccination cycle to check if you have achieved a satisfactory response. If not, your doctor will indicate the possibility of needing additional doses.
Other medicines and Twinrix Adult
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before receiving this vaccine.
It is not known whether Twinrix Adult passes into breast milk, but it is not expected to cause problems for breastfed babies.
Twinrix Adult contains neomycin and sodium
Tell your doctor if you have had an allergic reaction to neomycin (an antibiotic).
This vaccine contains less than 1 mmol of sodium (23 mg) per dose; it is essentially "sodium-free".
3. How to administer Twinrix Adult
You will receive a total of three injections over a period of 6 months. Each injection will be given on a separate visit. The first dose will be given on the chosen date. The other two doses will be given one month and six months after the first dose.
- First dose: on the chosen date
- Second dose: 1 month later
- Third dose: 6 months after the first dose
A total of 3 doses of Twinrix Adult can also be administered over 1 month. This vaccination schedule can only be given to adults who need rapid protection (e.g., travelers). The first dose will be given on the chosen date. The other two doses will be given 7 and 21 days after the first dose. A fourth dose is recommended 12 months later.
- First dose: on the chosen date
- Second dose: 7 days later
- Third dose: 21 days after the first dose
- Fourth dose: 12 months after the first dose
Your doctor will inform you if additional doses and future booster doses are needed.
As indicated in section 2, a low response to the vaccine, possibly without achieving protection against hepatitis B, is more frequent in elderly subjects, in men more than in women, in smokers, in obese people, and in people with chronic diseases, or those receiving some type of medication. Your doctor may recommend that you have a blood test after completing the vaccination cycle to check if you have achieved a satisfactory response. If not, your doctor will indicate the possibility of needing additional doses.
If you miss one of the scheduled injections, talk to your doctor to schedule another visit.
Make sure you complete the full vaccination cycle of three injections. Otherwise, you may not be fully protected against the diseases.
Your doctor will administer the Twinrix Adult injection into the upper arm muscle.
The vaccine must not be injected subcutaneously (deeply) or intramuscularly into the buttock, as protection may be lower.
The vaccine should never be injected into a vein.
If you have any further questions on the use of this vaccine, ask your doctor or pharmacist.
