Kyzatrex is an FDA-approved oral testosterone replacement therapy (TRT) prescribed for adult men diagnosed with hypogonadism due to specific medical conditions. As of February 2025, the FDA has removed the previous boxed warning related to cardiovascular risks for all testosterone products, including Kyzatrex.

Potential Risks and Warnings:

  • Increased Blood Pressure:
    Kyzatrex may raise blood pressure, potentially increasing the risk of serious cardiovascular events such as heart attack or stroke. Ensure blood pressure is adequately controlled before starting therapy, and regularly monitor it throughout treatment.

  • Polycythemia (Elevated Red Blood Cell Count):
    Treatment with Kyzatrex may elevate red blood cell counts, increasing the risk of blood clots. Regularly monitor hematocrit levels before and during therapy.

  • Prostate Health Risks:
    Testosterone therapy can worsen symptoms of benign prostatic hyperplasia (BPH) and may increase the risk of prostate cancer. Regular prostate examinations and PSA monitoring are recommended before and during therapy.

  • Risk of Venous Thromboembolism (VTE):
    Blood clots in veins, such as deep vein thrombosis (DVT) or pulmonary embolism (PE), have been reported with testosterone products, including Kyzatrex. Seek immediate medical attention if symptoms occur.

  • Potential for Abuse:
    Testosterone, including Kyzatrex, is classified as a Schedule III controlled substance due to its potential for misuse and abuse. Misuse may result in serious cardiovascular and psychological side effects.

Contraindications:
Do not use Kyzatrex if you:

  • Have known or suspected prostate or breast cancer.

  • Are allergic to testosterone or any components in Kyzatrex.

  • Are pregnant, as testosterone may harm an unborn child.

  • Have low testosterone unrelated to a recognized medical condition, such as low testosterone due to aging alone.

Common Side Effects:
The most common side effect reported with Kyzatrex is high blood pressure (hypertension).

Consultation and Monitoring:
Before starting Kyzatrex, disclose your complete medical history to your healthcare provider. Adherence to prescribed dosages and regular follow-up appointments for monitoring blood pressure, blood counts, and prostate health are essential.
