Duovir-N Tablets - Active Ingredient And Product Information

Duovir-N Tablets are a combination of three drugs namely zidovudine, lamivudine and Nevirapine that are commonly used in the management of the Human Immunodeficiency Virus (HIV) infection. Zidovudine and lamivudine belong to the nucleoside analogue class of antiretroviral drugs which act by terminating the growth of the DNA chain and inhibiting the reverse transcriptase (RT) of HIV. Nevirapine is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It acts by directly inhibiting Reverse Transcriptase.
The active ingredients contained in Duovir-N Tablets is zidovudine, lamivudine and Nevirapine.

Duovir-N - Warnings and Precautions

Hepatotoxicity and Hepatic Impairment
Severe, life threatening and, in some cases, fatal hepatotoxicity, including fulminant and cholestatic hepatitis, hepatic necrosis and hepatic failure, have been reported in patients treated with nevirapine.
Skin Reactions
Severe and life-threatening skin reactions, including fatal cases, have been reported with nevirapine treatment, occurring most frequently during the first 6 weeks of therapy. These have included cases of Stevens-Johnson syndrome, toxic epidermal necrolysis and hypersensitivity reactions characterized by rash, constitutional findings and organ dysfunction, including hepatic failure.
Nevirapine must not be used as a single agent to treat HIV or added on as a sole agent to a failing regimen. As with all other NNRTIs, resistant virus emerges rapidly when nevirapine is administered as monotherapy.
Immune Reconstitution Syndrome
Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including lamivudine, zidovudine and nevirapine. During the initial phase of combination antiretroviral treatment, patients whose immune system responds may develop an inflammatory response to indolent or residual opportunistic infections.
