TRIUMEQ PD Rx

Tabs and tabs for oral susp are not interchangeable on a mg per mg basis. Screen for presence of HLA-B*5701 allele prior to starting therapy or reinitiation; if (+), abacavir is contraindicated. Discontinue immediately if hypersensitivity is suspected, regardless of HLA-B*5701 status and even when other diagnoses are possible. If hypersensitivity cannot be ruled out, do not restart. If stopped for reasons other than hypersensitivity, restart only if medical care can be readily accessed. Test for the presence of HBV infection in all patients prior to or when initiating therapy. Lamivudine not established for chronic HBV infection; if treatment is initiated in patients co-infected with HIV and HBV, additional treatment should be considered for chronic HBV (if not, use alternative regimen). Monitor closely for severe acute exacerbations of HBV in patients co-infected with HBV and HIV for several months after stopping treatment (discontinuing therapy may exacerbate HBV infection); if appropriate, initiate anti-hepatitis B therapy may be warranted. Increased risk for worsening/development of elevated transaminases in patients with underlying hepatitis B or C; monitor for hepatotoxicity. Suspend if lactic acidosis or pronounced hepatotoxicity (eg, hepatomegaly, steatosis) occurs. Underlying risk of coronary heart disease (eg, hypertension, hyperlipidemia, diabetes, smoking). Renal impairment (CrCl <30mL/min): not recommended; if lamivudine dose reduction is required, use individual components; (CrCl 30–49mL/min): monitor for hematologic toxicities; if new or worsening neutropenia or anemia develop, adjust lamivudine dose. Mild hepatic impairment: not recommended; if abacavir dose reduction is required, use individual components. Women. Obesity. Elderly. Embryo-fetal toxicity: increased risk of neural tube defects (assess risks/benefits; consider alternative treatment at time of conception through 1^st trimester or if pregnancy is confirmed). Pregnancy: exclude status prior to initiation. Advise females of reproductive potential to use effective contraception. Nursing mothers: not recommended.
