Zanosar Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Zanosar (streptozocin) is an antineoplastic medication used to treat cancer of the pancreas. Common side effects of Zanosar include nausea, vomiting, loss of appetite, diarrhea, drowsiness, confusion, depression, swelling, redness, burning, or tenderness at the injection site. Other serious side effects include allergic reaction, kidney damage, or liver problems.
The daily dosage recommendation for Zanosar is 500 mg/m2 of body surface area for five consecutive days every six weeks. The recommended weekly dosage is 1000 mg/m2 of body surface area per week for the first two weeks, at which point dosage may be increased but not exceed 1500 mg/m2 of body surface area in a single dose. Talk to your doctor if you have renal disease or take medications that affect the kidney as these may increase your risk of renal toxicity. Zanosar may interact with "live" vaccines. Caution should be taken if you take Zanosar while pregnant and should only be used if the potential benefit outweighs the potential risk to the fetus. Do not take Zanosar if you are breastfeeding.

Zanosar FDA Prescribing Information: Side Effects
Most patients treated with ZANOSAR have experienced severe nausea and vomiting, occasionally requiring discontinuation of drug therapy. Some patients experienced diarrhea. A number of patients have experienced hepatic toxicity, as characterized by elevated liver enzyme (SGOT and LDH) levels and hypoalbuminemia.
Hematological toxicity has been rare, most often involving mild decreases in hematocrit values. However, fatal hematological toxicity with substantial reductions in leukocyte and platelet count has been observed.
Two cases of nephrogenic diabetes insipidus following therapy with ZANOSAR have been reported. One had spontaneous recovery and the second responded to indomethacin.
Spontaneous reports have been received of local inflammation (i.e., edema, erythema, burning, tenderness) following extravasation of the product. In most cases, these events resolved the same day or within a few days.
