Testim Heart Attack Information

Testim Heart Attack Information

Testim (testosterone gel) is known to increase the risk of blood clots in the legs. If a blood clot obstructs a coronary artery in the heart, it can potentially cause a heart attack.

In January 2014, the U.S. Food and Drug Administration (FDA) launched an investigation into two studies linking testosterone and heart attacks. The study that prompted the investigation was published in November 2013 — researchers found a 30% increased rate of heart attack, stroke, and death in older men on testosterone therapy.

The FDA is also investigating a study published in PLOS One linking testosterone to a doubled risk of heart attack for men over 65, and a tripled risk for men with heart disease.

FDA Requires Warnings About Testim Heart Attack Risk

In a Safety Communication published in March 2015, the FDA required the manufacturer of Testim to update the label to warn about a possible increased risk of heart attack. The FDA also asked for new clinical trials to assess the long-term heart attack risk of testosterone therapy. Finally, the FDA clarified that testosterone therapy is not approved or recommended for “Low T” associated with aging. Click here to read more.

Patients using Testim should seek medical attention immediately if they develop symptoms of a heart attack, such as:

  • Chest pain
  • Shortness of breath or trouble breathing
  • Weakness in one part or one side of the body
  • Slurred speech

Heart Attack Overview

Heart attacks occur when the arteries that supply the heart muscle with oxygen-rich blood (coronary arteries) are blocked, usually by a blood clot or fatty plaque. This “starves” the heart muscle of oxygen, which causes tissue damage within a few minutes.


  • Chest pain, tightness, squeezing, crushing, or full feeling
  • Upper body discomfort
  • Dizziness
  • Light-headedness
  • Fatigue (tiredness)
  • Shortness of breath
  • Excessive sweating

What Should I Do?

Call 9-1-1 right away if you or someone you know is having a heart attack. If the person is unconscious or unresponsive, perform 1 minute of CPR and call 9-1-1. The average person waits 3 hours to seek treatment for a heart attack, and many die before they get to a hospital. The sooner treatment begins, the better your long-term prognosis. When paramedics arrive, they can begin life-saving treatments on the way to the hospital, including:

  • Supplemental oxygen
  • Aspirin (blood-thinning medication that can prevent more blood clots)
  • Heart medications (nitroglycerin)
  • Pain-relieving medications
  • Defibrillator (can re-start heart if it stops beating)
