Shelf life and expiration date of Viagra and sildenafil

Viagra and its generic counterpart sildenafil, as well as other erectile dysfunction (ED) drugs like Cialis or Stendra, typically remain chemically potent for about two years from the manufacturing date. Like all medications, Viagra has an expiration date, after which it may lose its efficacy and render itself ineffective if not stored properly.

Breakdown of the active ingredient sildenafil citrate

Over time, the active ingredient in Viagra, sildenafil citrate, begins to break down. This breakdown leads to a reduction in its inhibiting effect on PDE5, which is crucial for its effectiveness in treating erectile dysfunction.

Reduced effectiveness in treating erectile dysfunction

You may not notice as effective of a response when you take Viagra or sildenafil after its expiration date. The chemicals have broken down, potentially causing the medication to be less effective in combating ED.

Potential side effects of taking expired Viagra or sildenafil

Expired Viagra or sildenafil can interact with bodily tissues and functions in unexpected ways.

Some potential side effects of taking expired Viagra or sildenafil include vision problems, feeling itchy, nausea, stomach pain, diarrhea, seizures, and heart attacks.

FDA recommendations on using drugs past their expiration dates

According to the FDA, it is not recommended to use drugs past their expiration dates due to the stability uncertainty. Expired medications may be less effective due to a change in chemical composition over time.

The impact of environmental factors on the potency of expired medications

Medicines exposed to high heat or humidity may have degraded, leading to a weaker active ingredient. This degradation further reduces the potency and effectiveness of expired Viagra or sildenafil.

Risks and dangers of taking expired Viagra or sildenafil

Taking expired Viagra or sildenafil is risky and never a smart idea. The reduced effectiveness and potential side effects can be detrimental to your health. If you depend on it to fight your ED, make sure it is well within its expiry date.

Proper disposal of expired Viagra or sildenafil

If you have taken expired Viagra and noticed any of the mentioned side effects, stop using it immediately and dispose of it properly. Do not flush expired Viagra down the toilet, as it can be dangerous for the environment.

Consultation with a doctor and refilling prescriptions for Viagra or sildenafil

In case you need a new prescription, consult your doctor about refilling it. They can provide guidance on the proper usage and storage of Viagra or sildenafil, ensuring that you have an effective and safe medication to help you manage your erectile dysfunction.
