Before taking Viagra (sildenafil), carefully review potential health risks. This medication isn’t suitable for everyone. Understanding contraindications is key to safe use.
Heart conditions are a major concern. Viagra can lower blood pressure, potentially causing dangerous drops in individuals with heart disease, angina, or uncontrolled high blood pressure. Consult your doctor if you have any heart-related issues. Recent heart attack or stroke also categorically rule out Viagra use. Always discuss your medical history with your physician.
Certain medications interact negatively with Viagra. Nitrates, often prescribed for chest pain, are a significant example. Combining these dramatically increases the risk of dangerously low blood pressure. Similarly, some antifungal and antibiotic medications can affect Viagra’s metabolism. Complete transparency with your doctor about all medications is paramount.
Eye problems such as retinitis pigmentosa can be exacerbated by Viagra, possibly leading to vision impairment. Similarly, known liver or kidney disease presents significant risks, potentially causing adverse reactions. Openly discussing all pre-existing conditions is crucial before starting treatment.
Deformities of the penis (such as Peyronie’s disease) can be worsened by Viagra use, leading to painful erections. Also, men with a history of priapism (prolonged and painful erections) should absolutely avoid this medication. Again, a complete and frank discussion with your healthcare provider is indispensable.

Contraindications for Viagra (Sildenafil)
Viagra, or sildenafil, is not suitable for everyone. Before taking it, discuss potential risks with your doctor. Serious health problems can be exacerbated by Viagra.
Heart Conditions
Avoid Viagra if you have a history of heart attack, stroke, or unstable angina. It can strain your heart. Likewise, avoid it if you have uncontrolled high blood pressure or low blood pressure. Your doctor can assess your suitability.
Other Medical Conditions
Certain eye conditions like retinitis pigmentosa necessitate caution. Viagra might worsen these. Also, avoid it if you have a bleeding disorder or stomach ulcers. It can increase the risk of bleeding.
Medications Interactions
Some medications interact negatively with Viagra. Examples include nitrates (often prescribed for chest pain), alpha-blockers (used for high blood pressure and prostate issues), and certain antifungal medications. Always inform your doctor of all medications, supplements, and herbal remedies you are taking. Incorrect interactions can be dangerous.
Contraindications Summary
| Condition | Reason for Contraindication |
|---|---|
| Heart attack, stroke, unstable angina | Increased risk of cardiovascular events |
| Uncontrolled high or low blood pressure | Potential for dangerous blood pressure fluctuations |
| Retinitis pigmentosa | Risk of vision problems |
| Bleeding disorders | Increased risk of bleeding |
| Stomach ulcers | Increased risk of bleeding |
| Concurrent nitrate use | Severe hypotension |
| Concurrent alpha-blocker use | Significant blood pressure drop |
Kidney and Liver Issues
Kidney or liver problems can affect how your body processes Viagra. Reduced kidney or liver function necessitates careful monitoring and dosage adjustments by your doctor, or may even be a contraindication depending on the severity.
Heart Conditions and Viagra
Viagra, or sildenafil, interacts significantly with several heart conditions. If you have heart disease, you should never take Viagra without first consulting your doctor.
Specific Heart Conditions to Consider
Certain heart conditions pose a higher risk when combined with Viagra. These include unstable angina (chest pain), uncontrolled high blood pressure, and a history of heart attack or stroke within the past six months. Also, men with heart valve problems or those taking nitrates (medications for chest pain) should absolutely avoid Viagra. These interactions can lead to dangerously low blood pressure, resulting in dizziness, fainting, or even more serious complications.
What to Do
Before using Viagra, discuss your complete medical history, including any cardiovascular issues, with your physician. They will assess your risk and determine if Viagra is safe for you. Honest communication with your doctor is paramount to your safety.
Alternative Treatments
If Viagra is deemed unsafe, your doctor can discuss alternative treatment options for erectile dysfunction, such as other medications or lifestyle changes. These alternatives might be suitable for individuals with heart conditions who want to improve their erectile function.
Viagra and Blood Pressure Medications
Combining Viagra (sildenafil) with certain blood pressure medications can be risky. Specifically, nitrates, often prescribed for angina (chest pain), interact dangerously with Viagra, causing a drastic drop in blood pressure. This combination may lead to dizziness, fainting, or even a heart attack.
Alpha-blockers, another class of blood pressure medications, can also interact negatively with Viagra. While not as severe as the nitrate interaction, this combination can result in significantly lower blood pressure, potentially causing lightheadedness or fainting. Consult your doctor before using Viagra if you’re taking alpha-blockers.
Always inform your doctor about all medications you’re taking, including over-the-counter drugs and supplements, before starting Viagra. This includes blood pressure medications. Your doctor will assess your individual health status and determine if Viagra is safe for you, considering any potential drug interactions.
If you experience any unusual side effects, such as severe dizziness or chest pain after taking Viagra, seek immediate medical attention. Your doctor may adjust your medication or recommend alternative treatments for erectile dysfunction.

Eye and Vision Problems & Viagra
Viagra, or sildenafil, can affect your vision. Before taking it, discuss any existing eye conditions with your doctor.
Some users report temporary visual changes. These include:
- Blurred vision
- Changes in color perception
- Increased sensitivity to light
These side effects are usually mild and temporary. However, rarely, more serious problems can occur.
Non-arteritic anterior ischemic optic neuropathy (NAION) is a rare but serious side effect. It causes sudden vision loss. If you experience sudden vision loss, seek immediate medical attention.
Pre-existing eye conditions increase your risk of these complications. These include:
- Retinitis pigmentosa
- Severe high blood pressure
- Diabetes
- Existing optic nerve problems
Recommendations:
- Honestly disclose all your medical conditions, particularly eye problems, to your doctor before starting Viagra.
- Report any visual changes, even minor ones, to your doctor immediately.
- Follow your doctor’s instructions carefully regarding dosage and frequency.
- Consider alternatives if your doctor advises against Viagra due to your eye health.

Other Contraindications and Precautions
Avoid Viagra if you have a history of heart problems, including recent heart attack or stroke. Consult your doctor before use if you have high or low blood pressure, irregular heartbeat, or angina.
Specific Medications and Interactions
Viagra interacts negatively with certain medications, including nitrates (used to treat chest pain) and alpha-blockers (used to treat high blood pressure and enlarged prostate). Concurrent use can cause a dangerous drop in blood pressure. Always inform your physician of all medications, supplements, and herbal remedies you are taking. This includes recreational drugs, as some may increase the risk of adverse effects.
Retinitis pigmentosa, a rare eye disease, also represents a contraindication. Individuals with a known history of vision problems should discuss Viagra use with their ophthalmologist before initiating treatment. Similarly, patients with sickle cell anemia, multiple myeloma, or leukemia should exercise caution and consult their healthcare provider. Severe liver or kidney disease may also necessitate a different treatment approach.
Finally, remember that Viagra is intended for adult men only. Use in children or women is contraindicated. Always follow your doctor’s instructions carefully and report any unusual side effects immediately. Safe use requires careful monitoring and communication with your medical professional.
