Risks and Side Effects

What you should know

These are not all the risks and side effects of TRIUMEQ, and this information does not replace talking with your healthcare provider about your medical conditions or treatment. For more information, talk to your healthcare provider and refer to the Medication Guide for TRIUMEQ.

What is the most important information I should know about TRIUMEQ?

TRIUMEQ can cause serious side effects, including:

  • Serious allergic reactions (hypersensitivity reaction) that can cause death have happened with TRIUMEQ and other abacavir-containing products. Your risk of this allergic reaction to abacavir is much higher if you have a gene variation called HLA-B*5701. Your healthcare provider can determine with a blood test if you have this gene variation.

If you get a symptom from 2 or more of the following groups while taking TRIUMEQ, call your healthcare provider right away to find out if you should stop taking TRIUMEQ.

Group Symptom(s)
Group 1 Fever
Group 2 Rash
Group 3 Nausea, vomiting, diarrhea, abdominal (stomach area) pain
Group 4 Generally ill feeling, extreme tiredness, or achiness
Group 5 Shortness of breath, cough, sore throat

A list of these symptoms is on the Warning Card your pharmacist gives you. Carry this Warning Card with you at all times.

If you stop TRIUMEQ because of an allergic reaction, never take TRIUMEQ (abacavir, dolutegravir and lamivudine) or any other medicine that contains abacavir or dolutegravir (EPZICOM, TIVICAY, TRIZIVIR, or ZIAGEN) again.

  • If you have an allergic reaction, dispose of any unused TRIUMEQ. Ask your pharmacist how to properly dispose of medicines.
  • If you take TRIUMEQ or any other abacavir-containing medicine again after you have had an allergic reaction, within hours you may get life-threatening symptoms that may include very low blood pressure or death.
  • If you stop TRIUMEQ for any other reason, even for a few days, and you are not allergic to TRIUMEQ, talk with your healthcare provider before taking it again. Taking TRIUMEQ again can cause a serious allergic or life-threatening reaction, even if you never had an allergic reaction to it before.

If your healthcare provider tells you that you can take TRIUMEQ again, start taking it when you are around medical help or people who can call a healthcare provider if you need one.

  • Worsening of Hepatitis B virus (HBV) infection. If you have HBV infection and take TRIUMEQ, your HBV may get worse (flare-up) if you stop taking TRIUMEQ. A “flare-up” is when your HBV infection suddenly returns in a worse way than before.
    • Do not run out of TRIUMEQ. Refill your prescription or talk to your healthcare provider before your TRIUMEQ is all gone.
    • Do not stop TRIUMEQ without first talking to your healthcare provider.
    • If you stop taking TRIUMEQ, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your liver function and monitor your HBV infection. It may be necessary to give you a medicine to treat hepatitis B. Tell your healthcare provider about any new or unusual symptoms you may have after you stop taking TRIUMEQ.
  • Resistant HBV. If you have human immunodeficiency virus-1 (HIV-1) and HBV, the HBV can change (mutate) during your treatment with TRIUMEQ and become harder to treat (resistant).
  • For more information about side effects, see “What are the possible side effects of TRIUMEQ?”

Who should not take TRIUMEQ?
