SILDENAFIL Citrate Side Effects, Dosage



Sildenafil citrate is a medication most frequently available as oral tablets or pills, that is prescribed by doctors to treat erectile dysfunction (most commonly know as ED). It shares the same market segment as Cialis (whose generic version is known as tadalafil), Levitra (vardenafil), and Stendra (avanafil). Unlike ExtenZe, or newly released VigRX, it is not an Over The Counter drug which means that it requires a prescription. (Summer 2020 ExtenZe coupon here)

As An ED Treatment, Does SILDENAFIL Really Work?

As a generic name it might not be as well known as its famous counterpart. It is basically the same drug as Viagra aka “The Blue Pill”, in sum it is a 100% generic Viagra. As such it has been proven to be quite effective in most cases of erectile dysfunction plaguing men over 40. However much like Viagra, there can be serious side effects to watch for (see below).

How Long Does SILDENAFIL Last?

Before giving any indication as to how long Sildenafil’s effects last, it is important to underscore that no effect will be neither visible nor felt if the patient is not aroused. Effects are also directly correlated to dosage. Overall, Sildenafil will last 12 hours with a “peak” felt within 70 minutes after taking it. However its effects depend on the patient. For some patients it will take longer to be felt, for others it will take barely 10 minutes.


The most common side effects include (but are not limited to):

  • Headaches
  • Nausea
  • Diarrhea
  • Hearing loss
  • Dizziness
  • Stomach pain
  • Eye sensitivity (blurred vision)

SILDENAFIL Dosage For ED Treatment. How Much Sildenafil Is Too Much?

Dosage depends on the focus of the treatment and the patient themselves. If it is used to treat erectile dysfunction then patients are prescribed between 5 mg and 20 mg, three times a day. Again it is important to keep in mind that the dosage will depend on the patient, and only a doctor can prescribe the right amount based on their knowledge of their patients, the extent of their erectile dysfunction, and their medical history.

SILDENAFIL Contraindications

Over time, various allergies to the drug have been identified, and some patients might simply not be able to take this medication as they have shown allergic predisposition to it.

Patients taking medications that include nitrates should not take it either . When it is combined with nitrates, it has for effect to dilate blood vessels, leading to a drop in blood pressure. In sum patients taking medications for low blood pressure should definitely not take Sildenafil. In addition patients taking any medication such as Riociguat (or similar) should also not take it either.

SILDENAFIL (Viagra) vs. TADALAFIL (Cialis) vs. VARDENAFIL (Levitra) vs. AVANAFIL (Stendra)

Those are all erectile dysfunction treatments introduced since the 1990s. They all work in a similar fashion but they have slight differences. Avanafil and Vardenafil are usually the fastest to produce results, generally under 15 minutes after absorption. All of them last around 5 hours with the exception of tadalafil whose effects can be felt for over 12 hours. All of them have their own potential side effects depending on dosage and the patient’s medical history.
