Pharmacist tips for Heplisav-B

pharmacist
  • You can usually get Heplisav-B if you have a mild illness, such as a cold. But if you feel very sick, you might need to wait until you feel better. Ask a healthcare professional if you're not sure whether you should get the vaccine.
  • Be sure you get both doses of Heplisav-B. You'll get your second dose 1 month after the first. Keep a record of your first dose and mark when your next one is due. If you miss your second dose, call your healthcare professional to reschedule it as soon as possible. Getting both doses helps provide full protection against hepatitis B.
  • It's common for your arm to feel sore after getting Heplisav-B. The soreness usually goes away within a few days. Gently moving your arm and using a cool compress can help you feel more comfortable.
  • If you have travel plans: Check if hepatitis B vaccination is recommended for where you're traveling. If it is, talk to your prescriber or pharmacist about getting vaccinated before your trip. Heplisav-B is one option for hepatitis B vaccination.
  • If you plan to donate blood: Wait at least 3 weeks after getting Heplisav-B before donating blood. The vaccine can make some hepatitis B test results look positive for a short time, even if you don't have hepatitis B. Waiting can help prevent incorrect test results and problems with donating blood.
  • Read the vaccine information statement for more information on Heplisav-B.

Risks and warnings for Heplisav-B

Heplisav-B can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Allergic reaction

Allergic reactions like anaphylaxis are possible with Heplisav-B. Your vaccinator might ask you to stay at the pharmacy or clinic for a short time after you get your shot. This is so they can help you if an allergic reaction happens. Get medical help right away if you have trouble breathing, swelling of your face or throat, hives, dizziness, or feel faint after getting Heplisav-B.

Weaker immune response in people with a weak immune system

  • Risk factors: Medical conditions that weaken the immune system | Taking medications that lower your immune system

If you have a weakened immune system, your immune system might not respond as strongly to Heplisav-B. This means you might have less protection against hepatitis B after vaccination.

Tell your vaccinator about your health conditions and medications before getting Heplisav-B. Conditions, like HIV or cancer, can weaken your immune system. Some medications, like high-dose steroids or transplant medications, can also weaken it. Your care team can discuss additional ways to help protect you from hepatitis B.
