Generic Viagra, also known as Sildenafil, is a widely prescribed medication for treating Erectile Dysfunction (ED).
ED is the inability of men or Assigned Males at Birth (AMAB) to get or maintain a firm erection.
Generic Viagra is a cost-effective alternative to the brand-name medicines Viagra.
Although it offers effective results, it has the potential to interact with other drugs, diseases, and food.
In this article, we will delve into comprehensive details on these interactions. Thus, providing valuable insights for men in the United States.
Interactions of Generic Viagra (Sildenafil)
Generic Viagra contains the active ingredient Sildenafil, which is a Phosphodiesterase Type 5 (PDE5) inhibitor.
It works by inhibiting PDE5 enzymes in the penis, which increases the cGMP levels.
cGMP is a molecule that helps dilate blood vessels, which improves blood flow to the penis.
This improved penile blood flow helps men or AMAB to get a firm and long-lasting erection.
But certain drugs, diseases, and food can interact with Generic Viagra (Sildenafil).
This can result in reduced effectiveness, increased side effects, or complications.
Drug interactions with Generic Viagra
Generic Viagra can interact with various medications, potentially leading to adverse effects.
To ensure safety, you must inform your doctor about all your medications.
These especially include Nitrates, alpha-blockers, antibiotics, etc.
1. Nitrates

Nitrates are commonly prescribed for treating chest pain (Angina) or heart problems.
Both medicines are vasodilators. If taken together, they may widen blood vessels excessively.
This can cause a severe drop in blood pressure. Thus, leading to dizziness, fainting, or even a heart attack.
2. Alpha-blockers
Alpha-blockers are prescribed for treating high blood pressure or prostate enlargement.
These can interact with Generic Viagra, resulting in low blood pressure.
3. Antibiotics and Antifungal drugs
Certain Antibiotics (Erythromycin, Clarithromycin) and Antifungal drugs (Ketoconazole) can interact with Generic Viagra.
They prevent your body from breaking down Generic Viagra. Thus, increasing the concentration of medicine in the bloodstream.
This can result in an increased risk of side effects.
4. Guanylate Cyclase (GC) stimulators
Guanylate Cyclase (GC) stimulators treat Pulmonary Arterial Hypertension (PAH).
These medications work by stimulating the enzyme guanylate cyclase. Thus, leading to increased levels of cyclic Guanosine Monophosphate (cGMP).
As mentioned, Generic Viagra also works by increasing the cGMP levels in the blood vessels.
If these medicines are taken together, they can potentiate the effects on the cGMP pathway.
Thus, lowering your blood pressure to dangerous levels.
5. Protease inhibitors
Protease inhibitors are used to slow down the progression of HIV.
They should not be taken in combination with Generic Viagra.
These inhibitors work by inhibiting certain enzymes in the liver, which are responsible for breaking down Generic Viagra.
If you take both medicines simultaneously, your body won’t be able to break down Generic Viagra.
As a result, it leads to higher levels of medication in the blood.
This increased concentration of Sildenafil can intensify its therapeutic effect. Thus, increasing the risk of side effects like prolonged erections.
6. Other Erectile Dysfunction pills
Other PDE5 inhibitors include Tadalafil, Vardenafil, and Avanafil.
Each of them has their own unique characteristics and are used to treat ED.
Since they all belong to the same class of medicine, they have similar mechanisms of action and effects on the body.
If taken together, they can result in complications.
Disease interactions with Generic Viagra
Individuals with pre-existing medical conditions should exercise caution when using Generic Viagra.
They can interact and can worsen specific health conditions.
The following are examples of disease interactions.
1. Cardiovascular Diseases
People with pre-existing heart conditions, like coronary artery disease or heart failure, should use Generic Viagra cautiously.
The medication can increase the strain on the heart due to its effects on blood pressure.
2. Liver or Kidney Problems
Liver or kidney impairment can affect how the body processes and eliminates medications.
This can increase medicine’s concentration in the body, which raises the risk of side effects.
Therefore, individuals with severe liver or kidney dysfunction may require dosage adjustments when using Generic Viagra.
3. Eye Disorders
Generic Viagra can cause visual changes by inhibiting PDE6. It may lead to temporary or permanent loss of vision.
So, people with pre-existing eye conditions, like Retinitis Pigmentosa, should avoid using Generic Viagra.
4. Blood disorders
Sildenafil (the active ingredient in Generic Viagra) affects blood flow, which can impact the coagulation process.
It may exacerbate bleeding disorders and lead to uncontrolled bleeding.
So, people with blood disorders like Sickle Cell Anemia or Leukemia should avoid using Generic Viagra.
Food interactions with Generic Viagra
While Generic Viagra can be taken with or without food.
However, certain dietary factors can interfere with the mechanism of action of Generic Viagra.
These include high-fat meals, grapefruit juice, and excessive alcohol consumption.
1. High-Fat Meals
Consuming a high-fat meal before taking Generic Viagra can delay its absorption into the bloodstream.
This results in a delayed onset of action by approximately one hour.
It also reduces its peak concentration in the bloodstream by 29%.
2. Grapefruit and Grapefruit Juice

This interaction may increase the concentration of the medication in the bloodstream.
Thus, leading to an increased risk of side effects.
Moreover, grapefruit or its juice tend to delay the absorption of Generic Viagra (Sildenafil).
3. Alcohol Consumption
Excessive alcohol intake can impair sexual function and decrease Generic Viagra’s effectiveness.
It can also increase the risk of adverse effects like dizziness, lightheadedness, and low blood pressure.
Conclusion
