Erectile Dysfunction Medication and Heart Conditions: What You Need to Know

If you're looking to get a Sildenafil prescription online in the EU and have a heart condition, you need clear, reliable information.

How it works — get your Sildenafil prescription in 4 steps

1. Fill the online medical questionnaire: It takes just 2–3 minutes to provide your health details.
2. A licensed EU doctor reviews your case in private: Our doctors assess your information, including any heart conditions and current medications, to ensure Sildenafil is safe and appropriate for you.
3. If appropriate, you receive a REMPE electronic prescription within 24 hours: The prescription is delivered to your private account and by email.
4. Pick up your medication at any EU pharmacy: Your prescription is valid across the entire EU.

Who qualifies for Sildenafil

Our EU-licensed doctors carefully evaluate each patient. They look for specific criteria to ensure Sildenafil is safe and effective for you, especially if you have a heart condition. Key considerations include:

• Your overall cardiovascular health: This includes assessing stable angina, recent heart attack or stroke history, and severe heart failure.
• Current medications: It's crucial to disclose all medications, especially nitrates (e.g., nitroglycerin, isosorbide dinitrate) and alpha-blockers. Sildenafil is strictly contraindicated with nitrates due to the risk of dangerous blood pressure drops.
• Blood pressure: Doctors assess if your blood pressure is well-controlled.
• Other health conditions: Diabetes, kidney, or liver issues can influence treatment decisions.

The doctor will determine if Sildenafil is appropriate for your specific health profile.

What Sildenafil actually does (and doesn't do)

Sildenafil, commonly known by brand names like Viagra, is a phosphodiesterase-5 (PDE5) inhibitor. It works by increasing blood flow to the penis when you are sexually stimulated. This helps you achieve and maintain an erection firm enough for satisfactory sexual intercourse. It does NOT automatically cause an erection; sexual stimulation is still required.

Sildenafil typically starts working within 30–60 minutes and its effects can last for up to 4 hours. It's important to have realistic expectations. Sildenafil is a tool to help with erectile dysfunction; it is not a cure for underlying conditions and will not increase sexual desire if it's not already present.

Side effects and when to stop

Like all medications, Sildenafil can cause side effects. Most are mild and temporary. Common side effects include headache, flushing, upset stomach, abnormal vision (blurred vision, a blue tinge to vision), nasal congestion, back pain, and dizziness.

You should stop taking Sildenafil and seek immediate medical attention if you experience:

• A sudden decrease or loss of vision.
• A sudden decrease or loss of hearing.
• An erection lasting longer than 4 hours (priapism).
• Chest pain, dizziness, or nausea during sexual activity.
• Symptoms of an allergic reaction (rash, hives, swelling of the lips, face, or tongue, difficulty breathing).

Always discuss any concerns with your doctor. Your EU-licensed doctor will advise you on potential risks based on your individual health profile.
