Precautions

Severe, potentially life-threatening, and fatal skin reactions (including Stevens-Johnson syndrome and toxic epidermal necrolysis) have been reported. Hypersensitivity reactions (characterized by rash, constitutional findings, and sometimes, organ dysfunction, including hepatic failure) have also been reported. Raltegravir and other suspect agents should be discontinued at once if signs or symptoms of severe skin reactions or hypersensitivity reactions develop (including, but not limited to, severe rash or rash accompanied by fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, facial edema, hepatitis, eosinophilia, angioedema). Clinical status including liver aminotransferases should be monitored and appropriate therapy initiated. A life-threatening reaction may result if discontinuation of raltegravir or other suspect agents is delayed following onset of severe rash.

Close monitoring of liver enzymes has been recommended.

The 25 and 100 mg chewable tablets contain about 0.05 and 0.1 mg phenylalanine, respectively, which can be harmful to patients with phenylketonuria.

Immune reconstitution syndrome has occurred during combination antiretroviral therapy. Patients responding to therapy may develop an inflammatory response to indolent or residual opportunistic infections and require evaluation and treatment.

Myopathy and rhabdomyolysis have been reported during clinical trials but the relationship of raltegravir to these events is unknown. Patients at greater risk of myopathy or rhabdomyolysis should take raltegravir with caution.

Raltegravir should be administered in combination with other antiretroviral agents. Use with other active agents will increase the likelihood of treatment response.

Safety and effectiveness have not been established in pediatric patients less than 2 years of age.

Dialysis

Hemodialysis: Raltegravir should be administered after a dialysis session since it is unknown how much may be removed by hemodialysis.
