Twinrix Dosage

Each Twinrix dose is 1 injection (1 mL) given into the shoulder muscle by a healthcare professional (HCP).

• Typical 3-dose series: Typically, you'll get 3 injections of Twinrix over a 6-month period. After your first shot, you can get your second shot 1 month later. Then, your third shot should be about 5 months after your second shot.

• Accelerated schedule (4-dose series): You'll receive the 3 injections of Twinrix over 1 month with a booster dose 1 year later. After your first dose, you can get your second dose 1 week later. You should get your third dose about 2 to 3 weeks after your second dose. Then, you'll need to get a booster dose of Twinrix about 1 year from the first shot you received.
