Sildenafil citrate, a substance that were destined to become one of the most recognizable drugs in the history of pharmacology under the brand name of Viagra, was approved for the treatment of erectile dysfunction (ED) back in 1998. The substance displayed excellent efficacy and safety of use over more than two decades of its patient-years, with its only significant drawback being the prohibitive price. A few years ago, the patent protection for Viagra held by its developer company Pfizer expired in Europe (2012) and partly in the U.S. (2017), which resulted in economically available generic Viagra pills flooding the market. This survey focuses on essential bits of information and popular questions about generic Viagra.


Sildenafil is a generic name for the active substance used in Viagra pills. The molecule was developed in the early 90s as a result of a research for a drug against pulmonary arterial hypertension (PAH). A stark secondary event of restorative effect on erectile function was soon observed in the course of the trials, and by 1998 Viagra as we know it today received its FDA approval as the first oral medication for erectile difficulty.

A drug produced by a non-developer company is called generic, a term deriving from the generic name of generic substance which is always identical to that used in the original drug. Generic manufacturing of sildenafil became legal as of 2012, with dozens of companies competing for acquisition of patent for production. The most economically available pills of generic Viagra are currently produced by Indian pharmaceutical companies with such resonant names in the industry as Ajanta Pharma, Cipla Ltd., Ranbaxy Laboratories, and others.

Generic Viagra is a full analog of the brand drug produced by any company that is not the original developer. A number of solid economical rationales behind the price formation for generically manufactured drugs brings the cost for the generic version of the pill up to 90% lower as compared to the brand-name drug.

Generic Viagra safety and efficacy are identical to those of the brand drug, provided that the pill is supplied by a reliable manufacturer. It is a telltale fact that Pfizer, the original developed of Viagra, is also engaged in generic production of sildenafil as a way of retaining the potential revenues from generic Viagra sales.


Generic Viagra is the first representative of its pharmacological class, which is inhibitors of phosphodiesterase type 5 (PDE5i). Sildenafil is a powerful vasodilator – a substance promoting relaxation of blood vessel walls and consequential smooth muscle fiber relaxation. As PDE5 enzyme is predominantly found in the erectile bodies of the penis (the two corpora cavernosa and the corpus spongiosum), the action of sildenafil conditions increase of blood flow and blood retention in the erectile bodies, resulting in hard, lasting and controllable erections. Generic Viagra has no effect on user’s sexual temperament; the drug potentiates erectile response, but provides no sexual stimulation or enhancement. Sexual stimulation is required for the drug to produce its health effect.


Taken prior to planned sexual activity, generic Viagra effects will set on in approximately 60 minutes and will last during the period of time equal 4 to 6 hours, subject to change from patient to patient. The duration of sildenafil effects largely depends on a number of factors, namely:

  • individual response towards sildenafil
  • severity of ED
  • etiology of ED
  • duration of ED
  • timing of the intake with regard to meal and / or alcohol intake
  • number of previous intakes
  • dose of the drug


Sildenafil is reported to be well tolerated by the majority of patients, the adverse events associated with the drug being transient and mild in their nature. Generic Viagra side effects are dose-dependent. The side effects of generic Viagra have tendency to subside with continued use. The risk of side effects is minimized by concomitant intake of a light meal with low fat content. Should they become bothersome or would not go away for a prolonged stretch of time, seek medical advice.

Common generic Viagra side effects:

  • Cephalgia
  • Nausea
  • Facial flushing, redness
  • Digestive disruption
  • Stomach ache
  • Myalgia
  • Lightheadedness
  • Slight alteration of color perception

Rare generic Viagra side effects:

  • Hearing loss
  • Tinnitus
  • Prolonged / painful erection
  • Temporary vision loss

Generic Viagra side effects requiring medical emergency:

  • Cardiac symptoms (palpitations, irregular heartbeat, angina)
  • Allergy signs (skin rash, wheezing, coughing, impaired breathing)
  • Priapism (erection that lasts more than 4 hours or is painful)


Generic Viagra dose titration is 25 mg, 50 mg and 100 mg. The average most commonly prescribed dose is generic Viagra 50 mg, which can be lowered to 25 mg or increased to 100 mg proceeding from induced health results and side effect history in individuals. Always follow dosing and posologic instructions from your prescriber. Do not take more than one recommended dose during 24 hours.

Take a pill of generic Viagra with a sufficient amount of water without crushing or chewing. Allow for effect onset to occur within ca 1 hour.


In double-blind, placebo-controlled, dose-controlled studies the efficacy of sildenafil 50 mg reached 69%. The data reported by developer company maintains efficacy of sildenafil at 82% with the administered dose of 100 mg.

Generic Viagra improves the penetration ability and maintenance ability, as well as shortens the sexual recovery periods. The drug indirectly improves psychological outlook and introspective perception of men affected with ED of both organic and psychological etiology thanks to removing the cause for performance anxiety (anticipated erectile failure and stress related to it).


Concomitant use of generic Viagra and alcohol potentiates the risk of severe and sudden drop in blood pressure. The pharmacokinetic effects of alcohol on sildenafil can be described as inhibitive; the onset of generic Viagra effects and their intensity will be compromised. The general guidelines are to avoid the combination or make it minimal.


Cocaine and other recreationally used drugs are known to reduce erectile ability, therefore it is not uncommon for cocaine users to take generic Viagra as a means of sexual enhancer. The interaction between sildenafil and cocaine is potentially fraught with risks of developing hallucinations, seizures, tremor and disorientation. The clinical data on the subject of concomitant use is limited to this research that focuses on a heart attack induced by simultaneous use of sildenafil, cocaine and alcohol and engaging in sexual activity. The contribution of each separate factor is hitherto unestablished.


Healthcare professionals give the following recommendations that increase the health outcomes of generic Viagra:

  • Follow dose instructions from your prescriber
  • Take generic Viagra in a fasted state or after a light meal.
  • Avoid taking alcohol, grapefruit and grapefruit juice
  • Avoid fatty or heavy meals prior to the use of generic Viagra
  • Continue taking generic Viagra; best results are achieved with a continuous use
  • Make sure you receive adequate sexual stimulation
  • Avoid coprescribed drugs decreasing sildenafil concentration in plasma (e.g., bosentan)


The onset of generic Viagra health effects is to be expected within an hour after the drug has been supplied. This estimate can be decreased or increased based on individual response, meal intake and sildenafil dose.


Sildenafil contained in generic Viagra is a vasodilatory and hypotensive agent, which means that in women it will mostly promote smooth muscle relaxation, decreased blood pressure and improved blood circulation.


The per-pill cost of generic Viagra 50 mg /100 mg varies from one pharmacy to another and depends on a variety of factors, such as the prime cost set by manufacturer, pharmacy mark-ups, complementary services (such as free online consulting by a healthcare specialist) incurred in the price, etc. The average cost of generic Viagra online fluctuates between $0.39 and $1.19, and can be further affects by current discounts, sales, promotions and bulk purchase shave-offs.


Generic Viagra is such a lifesaver! The price is chill, the quality is good. I achieve hard erections almost at every attempt. I get flushed as a side effect, but couldn’t be bothered less. I cannot see much difference from a way more expensive original.

“I have diabetes type 2 and I haven’t been able to achieve any penile hardness in soon 6 years now. I buy generic Viagra (to be exact, Kamagra) on repeat. Not because I am such a fan, I believe that the original is still better, but it’s too overpriced. Much to the credit of Indian Viagra producers, I get minimal side effects and I am quite satisfied with the results. “

“Generic Viagra is a decently effective and a moderately priced solution for my long-lasting ED problems. I use on average 4 pills weekly and have but one reason to complain, and it is disrupted bowel movement that I associate with the use of Viagra. “
Jackson, 47

“I get to feel the effects of generic Viagra already 20 minutes after taking the pill! Anything can get me going, a fleeting sexy image, a fantasy, the very thought of sex can get me hard. I have lots of side effects though, runny nose and next morning headaches, facial redness, you name it. Still generic Viagra is my pill of choice!”
