Yes, tadalafil can be used in certain situations. However, combination with nitrates is contraindicated, and people with certain cardiovascular diseases need medical evaluation before using the medication.
Hypertension can damage blood vessels and contribute to erectile dysfunction, which is why the two conditions commonly coexist.
Men with hypertension can, in many cases, use tadalafil, but the indication depends on blood pressure control, cardiovascular status, and the medications used. It is necessary to evaluate the patient’s cardiovascular status and medications before starting treatment. This evaluation is essential when asking can people with high blood pressure take tadalafil.
If nitrates are being used, tadalafil is contraindicated due to the risk of a drop in blood pressure.
Can people with high blood pressure take tadalafil?
In many cases, yes. The tadalafil can be used by men who take blood pressure medication. However, this combination depends on the specific medication and the patient’s health conditions, and it is necessary to assess possible drug interactions before prescribing.
Tadalafil and losartan
Losartan is an antihypertensive medication in the class of angiotensin II receptor blockers.
The combination of tadalafil and losartan can be considered when blood pressure is controlled, but it should be evaluated by the responsible cardiologist. If approved, the patient should be attentive and inform the doctor if there are symptoms that may indicate a drop in blood pressure, such as cold sweat, dizziness, or blurred vision upon standing.
Tadalafil and enalapril
Enalapril is an antihypertensive medication in the class of angiotensin-converting enzyme inhibitors.
The combination of tadalafil and enalapril is possible when blood pressure is under control and the patient is not using contraindicated medications. However, if symptoms such as severe dizziness, weakness, or fainting sensation occur, the patient should inform the physician responsible for treatment.
Tadalafil and amlodipine
A study on the interaction between tadalafil and amlodipine evaluated the simultaneous administration of the medications and did not identify clinically relevant changes.
This means that amlodipine did not significantly change the effects of tadalafil, nor did tadalafil meaningfully modify the effects of the antihypertensive.
But the study was conducted with healthy volunteers, without hypertension and erectile dysfunction. Therefore, the results do not allow one to state that the combination of the medications will behave the same way in men with high blood pressure and erectile problems.
Tadalafil and beta-blockers
The compatibility between tadalafil and beta-blockers depends on the specific medication used, the dose, blood pressure control, other health conditions, and other medications used. As both can lower blood pressure, the combination may increase this effect in some men.
The EAU highlights that the combination of PDE5 inhibitors with antihypertensives usually produces only small additional reductions in blood pressure, but concurrent use should be evaluated by a doctor, taking into account individual characteristics and the medications used by each patient.
Who should not take Tadalafil? (can people with high blood pressure take tadalafil?)
Tadalafil is not indicated for all men. Certain health conditions and combinations can increase the risk of adverse effects, such as a drop in blood pressure. Understand: can people with high blood pressure take tadalafil
Those who use nitrates
The package insert updated in January 2026 establishes contraindication to the concomitant use of tadalafil with any form of organic nitrate. Therefore, the use of nitrate-based medications is an absolute contraindication to tadalafil. Nitrates increase the production of cGMP, a substance produced in the cells of blood vessels in response to nitric oxide.
cGMP promotes relaxation of the vascular smooth muscle and favors vasodilation, increasing blood flow to the penis. Tadalafil, in turn, inhibits the PDE5 enzyme, which allows cGMP to remain active for longer.
Therefore, the combination of tadalafil and nitrates, such as nitroglycerin, isosorbide and other organic nitrates, can excessively increase cGMP activity and cause a significant drop in blood pressure, with a risk of dizziness, fainting and cardiovascular complications.
Those who use riociguat
Riociguat is a medication used in the treatment of adults with chronic or recurrent thromboembolic pulmonary hypertension when surgery is not possible or when the disease persists after surgical treatment.
Riociguat increases signaling of the cGMP pathway, while tadalafil inhibits PDE5 and reduces the degradation of this substance. Therefore, they should not be used together, because both can increase vascular relaxation and consequently lower blood pressure.
People with certain cardiovascular conditions
The package insert advises that oral medications for erectile dysfunction, such as tadalafil, should not be used by men whose cardiovascular health makes sexual activity inadvisable.
Therefore, cardiovascular risk should be considered before starting treatment, especially in men with cardiovascular disease or exertion-related symptoms.
Tadalafil and nitrates: why is the combination dangerous? (can people with high blood pressure take tadalafil?)
The combination of tadalafil and nitrates is contraindicated because it can excessively increase the vasodilatory effect and cause a sharp drop in blood pressure. Tadalafil and nitrates act on pathways related to vascular relaxation; when used together, this effect can be intensified and increase the risk of dizziness, fainting and cardiovascular complications.
A clinical study published in the Journal of the American College of Cardiology evaluated 150 men. Participants received tadalafil 20 mg or placebo and, subsequently, sublingual nitroglycerin.
The combination resulted in a greater reduction in blood pressure during the first 24 hours after drug administration. In some volunteers, standing systolic blood pressure, i.e., the measurement taken with the person standing, fell to below 85 mmHg.

Can people with high blood pressure take tadalafil every day?
Tadalafil has different dosing regimens and the choice depends on the indication, clinical conditions, and medical assessment.
Therefore, the daily use of tadalafil should occur only when there is an indication and individualized medical assessment. This evaluation allows verifying whether the regimen is appropriate, considering cardiovascular status, clinical conditions, and the other medications used.
Depending on the situation, a hypertensive person may take tadalafil daily. However, the dose should be defined according to the patient’s characteristics.
Is tadalafil safe for the heart?
The safety of tadalafil depends on the patient’s overall cardiovascular status. Controlled hypertension is not equivalent to unstable cardiovascular disease, a situation in which sexual activity may not be recommended until an appropriate medical evaluation takes place.
Even if blood pressure is controlled, tadalafil may not be indicated if the man has an unstable cardiovascular disease that could restrict sexual activity, such as uncontrolled arrhythmias and decompensated heart failure.
It is also necessary to review the medications used by the patient. Tadalafil can interact with some drugs and nitrates, for example, are absolute contraindications to the use of tadalafil.
Can high blood pressure be associated with erectile dysfunction?
Many men wonder whether high blood pressure causes impotence. Hypertension is related to erectile dysfunction because it can affect the health of blood vessels and compromise the blood flow necessary for an erection.
The AHA/ACC 2025 guideline highlights the relationship between hypertension, vascular dysfunctions, atherosclerosis, and erectile dysfunction.
Atherosclerosis can narrow and stiffen the arteries, impairing circulation. Hypertension, vascular dysfunction, and atherosclerosis also share risk factors, which helps explain the association between high blood pressure and erectile dysfunction.
