Kyzatrex Warnings/Precautions
Warnings/Precautions
Not substitutable with other oral testosterone undecanoate products. Not for use in women. Increases in BP can increase risk of major adverse cardiovascular events (MACE), including non-fatal MI, non-fatal stroke, CV death; use only for hypogonadal conditions associated with structural or genetic etiologies. Prior to treatment, consider baseline CV risk and ensure BP adequately controlled. Monitor BP after initiation or dose increase, and periodically thereafter; treat new-onset hypertension or exacerbations of preexisting hypertension. Reevaluate for continued treatment if CV risk factors or disease develops. Monitor hematocrit prior to initiation and approx. every 3 months; if elevation occurs, withhold until acceptable level. Increased risk of worsening BPH; monitor. Evaluate for prostate cancer prior to and during treatment. Monitor for venous thromboembolism; discontinue if suspected. Preexisting cardiac, renal or hepatic disease (discontinue if edema occurs). Discontinue and evaluate if signs/symptoms of hepatic dysfunction (eg, jaundice) occur. Possible sleep apnea in patients with obesity or chronic lung disease. Testosterone and/or other anabolic androgenic steroid abuse. Monitor serum testosterone, PSA, liver function, lipid profile, serum calcium (in cancer patients at risk for hypercalcemia/hypercalciuria) periodically. Elderly.
