Viagra is used for treating Erectile Dysfunction (ED) in men or Assigned Males at Birth (AMAB).

ED is a very prevalent sexual dysfunction in which men or AMAB cannot get or maintain an erection.

Many individuals may take Viagra to treat erection problems without paying attention to the adverse effects it may cause.

Viagra, containing Sildenafil, can interact with certain medicines, diseases, and food. This can lead to harmful consequences.

People with low blood pressure or heart diseases should not take Viagra to avoid disease interactions.

This article discusses people who should not take Viagra and Viagra contraindications.

Who should avoid taking Viagra

Viagra (Sildenafil) is not suitable for everyone.

Individuals who are allergic to the components of Viagra, taking Nitrates or Alpha-blockers, should avoid taking this medicine.

It is also crucial for people with severe cardiovascular conditions, liver or kidney issues, certain eye conditions, or a history of Priapism to be extra cautious before starting Viagra.

Open conversation with the doctor about your existing medical conditions and all the medications you’re currently using is necessary.

This allows doctors to determine whether Viagra is a safe and appropriate ED treatment option for you.

In addition to Nitrates and Alpha-blockers, several other medications can interact with Viagra and impact its effectiveness. To discover which specific drugs to avoid combining with Viagra, check out this article7 Drugs Not To Take With Viagra.

    The active salt in Viagra is Sildenafil Citrate. It might not be suitable for some people and cause allergic reactions.

    An allergic reaction may involve symptoms such as rash, itching, and hives. You may have Nausea, difficulty breathing, or dizziness in a severe allergic reaction.

    People who are allergic to Sildenafil should not take Viagra. You can use other ED medicines such as Tadalafil, Vardenafil, or Avanafil in such cases.

    Choosing the right ED medication can be confusing due to the many options available. To help you decide, we have an informative article – “Viagra vs Cialis vs Levitra: Which is Better“.

    Taking Nitrates as medicines

    Nitrates are useful in the treatment and management of Angina, which is a chest pain caused by reduced blood flow to the heart. 

    It is not usually life-threatening but is a warning sign of a heart attack or stroke.

    Both Nitrates and Viagra work by dilating blood vessels, which can lower blood pressure.

    If taken together, they can reduce blood pressure to dangerous levels, which can be life-threatening.

    Thus, people who should not take Viagra may also include people already taking Nitrates.

    For a clear understanding of what happens when you combine Nitrates with Viagra, check out this article – “Can You Take Viagra and Nitroglycerin Together“.

    Liver disease

    The liver is responsible for processing everything you consume, including food and drugs you may take. 

    Liver damage can result from multiple causes. Liver damage may develop into liver failure, also called Hepatic failure.

    According to Drugs.com, PDE-5 inhibitors such as Sildenafil (Viagra) can be used in patients with mild to moderate hepatic failure.

    PDE-5 inhibitors should not be used in patients with severe hepatic failure. This is because the body might be unable to metabolize the medication.

    As a result, the medicine will accumulate and stay in the body for longer. Thus, increasing the risk of side effects.

    You can deal with mild Viagra side effects without medical intervention. Find helpful tips for management tips in this article – “How to Get Rid of Viagra Side Effects– Solution.

    Heart disease

    Heart disease

    People with severe heart disease should not use Viagra. It may result in extremely low blood pressure. 

    Treatment of heart diseases such as Coronary Artery disease involves using Nitrates.

    As mentioned, Sildenafil (Viagra) and Nitrates have similar working.

    Both medicines widen the arteries to increase blood flow. It may cause extremely low blood pressure.

    People recovering from a stroke, heart attack, or other heart problem should avoid using Viagra at all costs.

    Low blood pressure (Hypotension)

    People with low blood pressure or Hypotension should not use Viagra to treat their erection problems.

    Sildenafil causes the blood vessels to relax, which can drop your blood pressure to extremely low levels.

    It may result in dizziness or lightheadedness.

    For a clear understanding of how Viagra affects blood pressure, refer to this article – “Does Viagra Raise Blood Pressure and Other Queries“.

    Eye diseases

    People with underlying vision problems or eye diseases should not take Viagra.

    A study suggests stopping the use of Sildenafil (Viagra) in cases where Central Serous Chorioretinopathy appears.

    Patients with a family history of Retinal Dystrophy should exercise caution before taking Viagra.

    Viagra works by inhibiting the PDE-5 enzymes to increase blood flow. As per an article, this process can also affect a related retinal enzyme to cause a rapid or gradual loss of vision. 

    Viagra can also interact with a rare inherited eye disease called Retinitis Pigmentosa.

    Sickle Cell Anemia, Leukaemia, or Multiple Myeloma

    The presence of skin conditions such as Leukaemia or Multiple Myeloma can affect Viagra’s efficacy. This may result in adverse effects.

    Leukaemia is the cancer of blood cells, while Multiple Myeloma is the cancer of bone marrow.

    Sickle Cell Anemia is a group of inherited red blood cell disorders. These disorders affect the shape of blood cells.

    Sickle Cell Disease patients should use Viagra carefully. As it can cause painful erections or Priapism in such patients.

    Peptic ulcer

    Peptic ulcers are open sores that may develop on the lining of the stomach, lower esophagus, and small intestine. The causes of peptic ulcers may be bacterial.

    Taking Viagra may increase the risk of bleeding. If you have a peptic ulcer, consult your doctor to help you decide the best course of treatment.

    Bleeding problem

    Viagra may enhance the risk of bleeding if you have problems like Haemophilia. 

    Hemophilia is a bleeding disorder in which the blood doesn’t clot normally. This can result in spontaneous bleeding or bleeding after an injury or surgery.

    It is usually an inherited disorder.

    Peyronie’s Disease or penis deformity

    Most men do not face erection problems due to a curved penis, which is usually not a cause for concern.

    In Peyronie’s Disease, fibrous scar tissue develops inside the penis. It may cause curved or painful erections.

    It is usually safe to take Viagra in such conditions. But you should consult your doctor before taking any medications. 

    In rare cases, taking Viagra may result in Priapism.

    Warning
    Priapism is a rare side effect of Viagra. If it happens, stop taking this medicine and contact your healthcare provider immediately.

    Final thoughts

    It is usually safe for most people to take Viagra for their erection problems. However, an underlying health condition or medicines can interfere with Viagra’s working and result in adverse effects.

    It is necessary to understand who should not take Viagra before consuming the tablet.

    Underlying health conditions may include liver, heart, or eye disease. Taking Viagra if you have low blood pressure can also affect your body negatively.

    Using medicines such as Nitrates can also affect the effectiveness of the medication.

    This will help them get a better understanding of the state of your health. And they will be able to prescribe the most suitable treatment.
