TRT and Blood Pressure: What Men Should Know

Men considering testosterone replacement therapy often ask about symptoms, hormone levels, and treatment options. Blood pressure deserves a place in that conversation, too. Testosterone products can increase blood pressure, so knowing your numbers before treatment and following them during care can help your clinician make informed decisions.

The connection between TRT and blood pressure can sound confusing, especially if you have heard that the FDA changed its cardiovascular warnings. Those changes addressed different pieces of evidence. Understanding the distinction can help you prepare for a useful conversation about your health.

Why blood pressure matters even when you feel well

High blood pressure usually causes no symptoms. Feeling energetic, sleeping well, or noticing improvements in other symptoms does not tell you whether your blood pressure is controlled. Untreated or uncontrolled hypertension can affect the heart, brain, kidneys, and eyes over time. The NHLBI explanation of high blood pressure symptoms  explains why measurements matter even when someone feels fine.

That makes blood pressure a separate part of follow-up. A testosterone blood test answers a hormone question; a blood pressure measurement answers a different question. Both deserve attention when your clinician evaluates treatment.

What the FDA changed about testosterone warnings

On February 28, 2025, the FDA announced changes to testosterone product labeling after reviewing the TRAVERSE cardiovascular trial and studies using ambulatory blood pressure monitoring. These monitors record blood pressure repeatedly during normal daily activities.

The agency recommended removing boxed-warning language about an increased risk of adverse cardiovascular outcomes. At the same time, it required blood pressure warning updates. Completed monitoring studies showed increased blood pressure across testosterone products as a class. Read the FDA testosterone labeling announcement  for the original explanation.

These findings support continued blood pressure monitoring. They do not predict that every individual will have the same change, and they do not establish that a particular formulation is free of blood pressure risk.

What TRAVERSE can tell us

The original TRAVERSE cardiovascular study  enrolled 5,246 men ages 45–80 with symptoms of testosterone deficiency, repeatedly low testosterone, and existing cardiovascular disease or high cardiovascular risk. It compared testosterone gel with placebo gel, with an average follow-up of about 33 months.

Testosterone met the study's criterion for cardiovascular safety for its main combined outcome: cardiovascular death, nonfatal heart attack, or nonfatal stroke. Some other adverse events occurred more often in the testosterone group. The results provide evidence for that study population and treatment setting; they cannot guarantee an individual's outcome or settle the safety of every formulation over a lifetime.

Before TRT: establish your blood pressure picture

Tell your clinician if you have hypertension, take blood pressure medication, or have a history of heart, kidney, or vascular disease. Bring recent readings if available, together with a list of prescription medicines, over-the-counter products, and supplements. This gives the discussion a clearer starting point than a single number from an old appointment.

Measurements can differ between the office and home. Some people have higher readings in a medical setting, often called white coat hypertension. Others have higher readings outside the office, called masked hypertension. The NHLBI guide to blood pressure diagnosis  describes how clinicians interpret these patterns. Your provider can decide whether additional measurements are needed before making a treatment decision.

Existing hypertension requires attention to how well it is controlled. For example, the current Depo-Testosterone prescribing information  calls for periodic blood pressure monitoring, especially in men with hypertension, and states that testosterone products are not recommended with uncontrolled hypertension. Ask your clinician how the warnings for your specific prescription apply to you.

Making home blood pressure readings useful

If your clinician recommends home monitoring, accurate technique helps make the results useful. The American Heart Association home monitoring guide  recommends a validated automatic upper-arm monitor with a cuff that fits correctly.

Avoid smoking, caffeine, and exercise for 30 minutes beforehand, and empty your bladder. Rest quietly for at least five minutes. Measure on bare skin while sitting with your feet flat and your arm supported at heart level. Avoid talking during the measurement. Take two readings one minute apart and record both.

Ask your clinician how often to measure and when to send results. Bring the monitor to an appointment so its readings and your technique can be checked. A log with dates and times helps the discussion stay focused on a pattern rather than memory.

During treatment: agree on a follow-up plan

Before leaving a visit, clarify when your next blood pressure check should happen, what readings should prompt a message, and who will manage an existing hypertension treatment plan. If different clinicians handle TRT and primary care, ask how relevant results will be shared.

Continue your prescribed hypertension care. Report new medical conditions or changes in medicines between visits. The NHLBI guidance for living with high blood pressure  emphasizes ongoing treatment, regular follow-up, and communication with your provider.

A rising reading deserves review, but one measurement does not explain its cause. Your clinician can compare it with your baseline, check measurement technique, and assess whether your treatment plan needs adjustment. Avoid changing testosterone or blood pressure medication yourself in response to a home reading.

Very high readings need prompt attention. A systolic reading above 180 or a diastolic reading above 120 warrants immediate medical contact. If accompanied by chest pain, difficulty breathing, weakness, vision changes, or trouble speaking, call 911 rather than waiting for a routine appointment.

Frequently asked questions about TRT and blood pressure

Can TRT raise blood pressure even if it was normal before treatment?

Yes. Testosterone products can increase blood pressure, which is why follow-up matters even when your starting readings are normal. The amount of change varies; a warning describes a possible risk rather than a prediction for every patient.

Can I discuss TRT if I already have hypertension?

Yes, but bring that history into the evaluation. Your clinician needs to consider control, your overall health, and the specific product's warnings. Uncontrolled blood pressure deserves medical attention before a treatment decision.

Does choosing gel instead of injections remove this risk?

No formulation should be assumed to eliminate blood pressure risk. The FDA's blood pressure findings were class-wide. Treatment choice requires a discussion of the specific prescription and your medical history.

Should I stop TRT after one higher home reading?

Contact your clinician for guidance rather than making an unsupervised medication change. Follow the plan you agreed on for repeat readings and reporting results. Severe readings or emergency symptoms require urgent care.
