Buy Real Viagra Online Without Prescription

ED is very common amongst men. About 150 million men were estimated to have experienced it in the year 1995, and based on projections, the number is expected to rise to about 320 million men.

Fortunately, ED can be treated with Viagra. Viagra improves sexual function by enhancing the effects of nitric oxide thus, bringing about an increase in blood flow to the penis. This drug is legal, and can be found in physical pharmacies around, as well as online. However, while a prescription is needed to make purchases from a physical pharmacy, real Viagra can be gotten online without one.

How Strong Is Viagra for ED Treatment?

Viagra is so effective that over 25 million men all over the world have gotten a prescription for it. Eighty-five percent (85%), eighty percent (80%), and, seventy-five percent (75%) of men who were placed on the 100 mg, 50 mg, and 25 mg dose of the drug respectively achieved an erection and maintain it for sexual intercourse, compared to the men (50%) who were on Placebo. The 50mg and 100 mg doses of Viagra enabled about 4 out of 5 men to achieve an erection and maintain it for sexual intercourse. This is a clear definition of how strong is for ED treatment.

Clinical experiment with the use of Viagra has been carried out on patients with diabetes mellitus, vascular diseases, psychogenic causes, spinal cord injuries, and after radical prostate surgery. About 70%-80% of men reported improvement in the quality of their erections. More than 50% of patients successfully had vaginal penetration with the aid of Viagra.

ED has been found to be linked with factors such as anxiety, stress, depression, fear of sexual underperformance and low self-esteem. If these factors responsible for the dysfunction can not be corrected, medications such as Viagra can then be used to help men achieve or restore their sexual function.

Viagra is administered orally 1 hour prior to sexual intercourse, if possible on an empty stomach. A fatty meal can reduce the absorption of Viagra.

How Does Viagra Work?

Erections are complicated. Getting an erection involves blood vessels, the smooth muscles of the penis and blood flow. For easy understanding, Viagra works by carrying out two basic tasks. They involve:

• relaxing the smooth muscles of the penis to enable the proper flow of blood to the penis for an erection;
• interfering with a chemical process having to do with cGMP and PDE5 to control erection and flaccidity.

Normally, upon sexual stimulation, Nitrogen Oxide (NO) is released to get the penile muscles relaxed to ensure normal blood flow for an erection. Thereafter, an enzyme called cGMP is produced. This enzyme controls the dilation and contraction of the blood vessels responsible for carrying blood in and out of the penis. After cGMP must have enacted the dilation of the blood to give rise to an erection, another enzyme called PDE5 starts breaking down cGMP down gradually to bring about flaccidity.

In men with erectile dysfunction, the rate at which PDE5 breakdowns cGMP is very fast, meaning that erections will not last or is not achieved at all. Viagra, being a PDE5 inhibitor (i.e it interferes with the action of PDE5), slows down the rate at which it destroys cGMP, hence leading to a longer-lasting erection hard enough for penetration. Viagra does this safely without posing any serious health risks (if taken correctly).

It is worthy of note that Viagra does not work absent of stimulation. So effects will not be noticed upon administration until sexual stimulation takes place.

How long Does the Pill Effect Last?

The duration which Viagra lasts upon administration is based on an individual factor, but its effect can last up to five (5) hours. This does not imply having an erection for 5 hours; it means erections will be easily achieved within this timeframe.

However, the average effect of Viagra tends to begin to diminish between two (2) and three (3) hours from the time the medication is taken. The rate at which it decreases depends on your body's metabolism, dosage, and other external factors.

Depending on body metabolism, getting an erection more than once with Viagra present is very doable.

Several factors can influence how long Viagra stays active in the body for different individuals. Some of these factors include:

• dosage;
• age;
• diet;
• medications like antibiotics;
• overall health;
• psychological state.

The last factor should be highlighted separately: anxiety, depression, or stress can all influence the response of your sexual stimulation. If you are not relaxed or comfortable during sex, or if you have performance anxiety due to past sexual experiences, the length and effectiveness of Viagra may be reduced.

To get the best results from Viagra, you should always give correct information about your current and past health conditions to your healthcare provider. It is also very important to inform the doctor of all other medications you may be using at the time you intend to begin a course of treatment with Viagra.

Contraindication and Usage Instructions

Contraindication in medicine refers to a condition that warrants halting the use of a particular medication on a patient due to negative aftereffects it may result in. Contraindication could be due to an underlying health condition a patient may be suffering.

There are certain health conditions that have contraindication with Viagra. As a result, men experiencing these conditions should create time for a meeting with their healthcare provider before using the drug.

Men with the following conditions should check with their doctor before using Viagra:

• men undergoing any condition that requires treatment with nitric oxide, nitrates, and organic nitrates;
• men with serious liver impairment;
• men who have kidney disease;
• men who experience hypotension;
• men with a history of a heart attack or stroke;
• men who have degenerative retinal disorders that may have been inherited.

Very importantly, men who have an underlying health condition and are taking some medications, are advised to take Viagra less often. This drug can be taken with or without food. However, taking it with a meal that is high in fat is highly discouraged. This is because fatty meals reduce the speed at which food in the stomach moves into the small intestine for absorption, and this ultimately means a prolonged time of action for the medication.

Viagra Side Effect

All drugs pose certain negative aftereffects with short or long-term use, and Viagra is not an exception. However, based on the fact that their benefits far outweigh their downsides, these drugs are approved for general use by regulatory bodies.

The side effects associated with Viagra (which contains the ingredients sildenafil citrate, magnesium stearate, titanium dioxide, etc.) are often mild conditions such as nausea, stomach upset, headaches, runny nose, muscle aches, and flushing. Other serious but less common negative aftereffects that may result from the use of this drug include rashes, accelerated heart rate, muscle aches and change in blood pressure.

There are also some very severe negative aftereffects that using this drug may result to, however, they are very rare. Some of these very rarely reported negative aftereffects of the drug include:

• an erection that refuses to relax for a long time (priapism). If you have an erection that exceeds 4 hours, you are advised to get medical help immediately. If not quickly treated, priapism can cause permanent damage to the penis;
• NAION, an acronym for non-arteritic anterior ischemic optic neuropathy is one of the very rare negative aftereffects associated with the use of this medication. It can be a sign of a severe eye problem, and it is characterized by loss of vision in one eye, or both. Users of this medication are advised to stop taking the drug immediately, and report to a doctor or healthcare provider in the event that eyesight is lost suddenly;
• decrease or loss in hearing. This is also one of the few extreme negative aftereffects associated with the use of this drug. Its symptoms include dizziness or ringing in the ears (tinnitus). Should any of these symptoms or any others that look like them be observed, treatment with this med should be halted, and immediate reports should be made to a doctor.

Generally, as the term implies, the less frequent negative aftereffects of Viagra are less common (very rare). On the other hand, more frequent negative aftereffects associated with it are often mild and go away after a short while (as the body gets used to it). Fortunately, not every user gets to experience these side effects. With strict adherence to the instructions of correct usage, they are less likely to take place.

More than one dose of this drug should never be taken within 24 hours as doing this could result in an overdose and could lead to serious complications.

Main Interactions with Another Substance

Drug interaction is a situation in which the actual and expected action of a drug, as well as its side effects, change due to its concomitant use with some other drugs, supplements, food or beverages.

Viagra interacts with certain substances, and some of them are as listed below:

• food: though this drug can be taken alongside a meal, there are certain ones that should be avoided while on the drug. Fatty foods such as french fries and cheeseburgers are a good example. They can slow down the activation time of the drug (i.e, they can cause the drug to take a longer time to start working);
• alpha-blocker: When Viagra is co-prescribed with drugs that are regarded as alpha-blocker, patients should be stable on alpha-blocker treatment before starting Viagra treatment. Some alpha-blockers include Cardura, Minipress, and terazosin;
• some antifungals: this drug interacts with certain antifungals such as Nizoral, and Onmel.

Users of this drug who may need to take some other medications due to one underlying condition or the other while on Viagra are advised to talk to their healthcare provider for proper guidance. This way, unnecessary discomforts or complications can be avoided.

Viagra User Reviews

There are lots of drugs for erectile dysfunction available in pharmacies and certain users have done their comparison and have written comprehensive reviews on them. A good number of first-time users of this drug have also given reviews. It was based on these reviews that this section was put together.

Lots of men (actually, the majority) have put in a good word for this drug. The most comments centering on its efficacy, very mild to no side effects, and ease of use.

However, the reviews are not all rosy. There are users who have complained bitterly about the experience they had with this drug. The reports all centered on one thing, and that is the varying side effects that were experienced while on the drug. Side effects such as stubborn and persistent headaches, nausea and stomach upset. While these side effects are truly associated with the use of this drug, they normally only last for a short while (if you ever get to experience them).

One thing stood out, however, when these complaints from customers were looked into. It was incorrect usage and non-adherence to prescription. Most of the users who were experiencing persistent side effects either took more than one dose in a single day or took it alongside drugs Viagra interacts with. Viagra must be used correctly to achieve max results.

Nevertheless, a good number of Viagra users have expressed satisfaction with the drug. They have achieved a good erection, easy penetration as well as sustained erection till orgasm.

In Summary, users of Viagra, especially those that take the drug correctly are very likely to enjoy a great sex life with little expense.
