Retrovir (zidovudine) Disease Interactions
There are 4 disease interactions with Retrovir (zidovudine):
Azt (Includes Retrovir) ↔ Bone Marrow Suppression
Severe Potential Hazard, High plausibility
Applies to: Bone Marrow Depression/Low Blood Counts
Zidovudine (AZT) may cause bone marrow toxicity, most commonly manifested as granulocytopenia and anemia, particularly in patients with advanced, symptomatic HIV disease. Thrombocytopenia not related to HIV may also occasionally occur. Zidovudine should be given with extreme caution to patients with preexisting bone marrow depression (indicated by a granulocyte count below 1000 cells/mm3 or hemoglobin less than 9.5 g/dL) or blood dyscrasias. Routine blood counts are recommended, and generally should occur more frequently in patients with advanced HIV disease. Dosage reductions may be necessary.
Azt/Telbivudine (Includes Retrovir) ↔ Myopathy
Severe Potential Hazard, High plausibility
Applies to: Myopathy, Myoneural Disorder
Prolonged use of certain nucleoside reverse transcriptase inhibitors (NRTIs) such as zidovudine and telbivudine may commonly cause myopathy, including rare cases of rhabdomyolysis. The myopathy may be dose-related and is characterized by persistent, unexplained muscle aches and/or weakness in conjunction with increases in creatine phosphokinase (CPK) values. Therapy with these NRTIs should be administered cautiously in patients with preexisting myopathy or a myoneural disorder, since it may delay the recognition or confound the diagnosis of a drug-induced musculoskeletal effect. Patients should be advised to report promptly any unusual muscle pain, tenderness or weakness, particularly if accompanied by malaise or fever. NRTI therapy should be interrupted if drug-related myopathy is suspected, and discontinued if myopathy is diagnosed.
Nrtis (Includes Retrovir) ↔ Hepatotoxicity
Severe Potential Hazard, Moderate plausibility
Applies to: Alcoholism, Liver Disease
Hepatotoxicity including lactic acidosis, severe hepatomegaly with steatosis, fulminant hepatitis, and hepatic failure has rarely been associated with the use of nucleoside reverse transcriptase inhibitors (NRTIs) alone or in combination with other antiretroviral agents. Therapy with NRTIs should be administered cautiously in patients with preexisting liver disease, a history of alcohol abuse, or hepatitis. Therapy should be suspended if clinical or laboratory findings suggestive of lactic acidosis or pronouced hepatotoxicity occur.
Nrtis (Includes Retrovir) ↔ Renal Dysfunction
Severe Potential Hazard, High plausibility
Applies to: Renal Dysfunction
Patients with clinically significant renal impairment may be at greater risk for toxicities and adverse effects from nucleoside reverse transcriptase inhibitors (NRTIs) due to decreased drug clearance. Dosage adjustments are recommended. In addition, these patients should be monitored closely during NRTI therapy, and dosages adjusted further if necessary.

Drug Interaction Classification
The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
