Twinrix Precautions
Serious side effects have been reported with Twinrix including the following:
- Allergic reactions. Tell your healthcare provider about any signs or symptoms of allergic reactions, which include the following:
- chest pain
- swelling of the face, eyes, lips, tongue, arms, or legs
- difficulty breathing or swallowing
- rash
- Latex. The tip caps of the prefilled syringes may contain natural rubber latex which may cause allergic reactions in latex-sensitive individuals.
- Fainting. Fainting can occur in association with administration of Twinrix.
- Limitations of vaccine effectiveness. Vaccination with Twinrix may not protect all individuals.
- Altered immunocompetence. If Twinrix is administered to immunocompromised persons, including persons receiving immunosuppressive therapy, the expected immune response may not be obtained.
- Moderate or severe illness. To avoid confusion when diagnosing between illness and possible vaccine adverse effects, vaccination with Twinrix should be postponed in persons with moderate or severe illness associated with fever unless they are at immediate risk of hepatitis A or hepatitis B infection.
- Multiple sclerosis. Results from 2 clinical studies indicate that there is no association between hepatitis B vaccination and the development of multiple sclerosis, and that vaccination with hepatitis B vaccine does not appear to increase the short-term risk of relapse in multiple sclerosis.
Do not get Twinrix if you had a severe allergic reaction (e.g., anaphylaxis) after a previous dose of any hepatitis A-containing or hepatitis B-containing vaccine, or to any component of Twinrix, including yeast and neomycin.

Twinrix and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications 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.
Twinrix falls into category C. No studies have been conducted in animals, and no well-controlled studies have been done in pregnant women. Twinrix should only be given to a pregnant woman if clearly needed.
Twinrix and Lactation
Tell your doctor is you are breastfeeding or plan to breastfeed.
It is not known if Twinrix 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, caution should be exercised if Twinrix is given to a nursing woman.
