Understanding Viagra and Its Main Ingredient, Sildenafil

Viagra is a well-known medication used to treat erectile dysfunction.It functions by improving blood flow to the penis and its effects can last up to 4 hours.The effect is typically strongest within 2 hours of consumption.

The main active ingredient in Viagra is sildenafil.

How Viagra Works in the Body

Viagra's functionality is credited to its active ingredient, sildenafil. This compound enhances the body's response to sexual stimulation by increasing blood flow to the penis, thus aiding men who suffer from erectile dysfunction. However, the effectiveness of this drug can fluctuate due to various factors.

The Shelf Life of Viagra: 2 Years

The official shelf life of Viagra is two years, as stated by various Sildenafil providers. According to PubChem, the shelf life of sildenafil citrate tablets, which are what make up Viagra, is 24 months post-manufacture. Beyond this period, the medication might lose some of its potency.

Factors Affecting Viagra's Potency Over Time

Viagra's efficacy can decrease due to changes in your body or health. Additionally, like most medications, Viagra can become less effective over time and expire if left unused for too long. Improper storage can also cause Viagra to lose its efficacy, rendering the drug ineffective.

Studies on Viagra's Effectiveness After 2 Years

Several studies have suggested that the anti-impotence drug sildenafil (Viagra) may stop working for many patients after two years. This implies that despite Viagra's initially high effectiveness, its efficacy may decrease over time for some users.

Reasons Why Viagra Might Lose Its Effectiveness

As Viagra ages, its active chemical components break down, which can result in a decrease in the drug's efficacy. External factors such as changes in a person's health or body can also influence how effective the drug is. For instance, an increase in tolerance to the drug might require a higher dose for the same effect.

What to Do If Viagra Loses Its Effectiveness

If Viagra seems to be losing its effectiveness, one recommended course of action is to consider switching to another medication in the same class, meaning another PDE5 inhibitor. Furthermore, it might be beneficial to discuss with your doctor the option of adjusting your dosage and frequency to improve the drug's efficacy.

Alternatives to Viagra Within the Same Medication Class

If Viagra becomes less effective over time, there are other PDE5 inhibitors available that might serve as potential alternatives. These medications work in a similar way to Viagra and could provide a viable solution if Viagra is no longer as effective.

Recommendations

Taking a daily dose of Viagra can help stop the intensity of the progression of erectile dysfunction. It also has other benefits, including improving your ability to urinate and improving your quality of life in general. As always, any changes to your dosage or medication should be discussed with your doctor to determine the best course of action for your unique situation.
