Tenofovir is an antiviral drug used in the management of hiv infection and chronic hepatitis b. It belongs to the class of nucleotide reverse transcriptase inhibitors that block viral replication. By inhibiting the viral enzyme reverse transcriptase it reduces the production of new virus particles in infected cells. This action helps restore immune function in hiv patients and slows liver damage caused by hepatitis b. The drug is metabolized to its active form Tenofovir diphosphate which competes with natural nucleotides and terminates viral dna synthesis. The sustained suppression of viral activity leads to decreased viral loads and improved long-term clinical outcomes in treated individuals.

Tenofovir is an oral antiviral medication used to treat chronic hepatitis b infection. It works by inhibiting the viral enzyme reverse transcriptase which the virus needs to replicate its genetic material. By blocking reverse transcriptase Tenofovir reduces the amount of hepatitis b virus in the bloodstream. The drug is classified as a nucleotide reverse transcriptase inhibitor and it is activated inside cells to its active form. Activated Tenofovir interferes with the viral polymerase leading to premature termination of dna synthesis. This mechanism helps the immune system control the infection and lowers the risk of liver damage over time. Tenofovir does not cure hepatitis b but it suppresses viral replication to very low levels. Long-term treatment with Tenofovir can improve liver function and extend life expectancy

Nausea is a frequently reported side effect of Tenofovir. Diarrhea occurs in some patients taking the medication. Headache is another common complaint. Fatigue may be experienced by individuals on treatment. Abdominal pain or discomfort can arise as a reaction. Some people notice a reduction in body weight while using the drug.

Tenofovir can cause nausea in some patients. Headache is another frequently reported symptom. Diarrhea may occur and is usually mild to moderate. Some users experience fatigue or a general feeling of tiredness. Abdominal discomfort such as stomach pain or upset can appear. Weight loss has been noted in a minority of cases. Mild skin rash or itching can develop in rare instances.
