What is Sildenafil & What Is It Used for?

Sildenafil is the active ingredient used in many sexual dysfunction medications for both men and women. Originally developed for pulmonary arterial hypertension, a blood pressure condition, it was discovered that it was much more effective at treating impotence. Following this, it was patented in 1996 by Pfizer, a multinational pharmaceutical company, and approved for use in 1998 by the Food and Drug Administration. It was subsequently sold under the brand name Viagra.

These days it is possible to buy sildenafil tablets under a wide range of other brand names, such as Kamagra, since the Pfizer patent has now expired. These alternative products are known as generic medications and are generally sold online at significantly cheaper prices than the original brand name products, to allow you to treat your sexual dysfunction without breaking the bank.

Are you tired of not being able to endure sexual encounters without losing your erection? Do you find that the idea of engaging in sexual activity makes you anxious rather than excited? Are you tired of sexual dysfunctions getting in the way of your otherwise happy relationship? If you answered yes to any of these questions, then continue reading to learn more about how sildenafil can help with your sexual dysfunction today.

How Does Sildenafil Work on the Body?

Sildenafil works in the same way that other medications work that belong to the group of drugs called PDE5 inhibitors. Once consumed, the medication works to widen blood vessels in the body. It does this by blocking a chemical in the body called PDE5. PDE5 breaks down another chemical in the body called cGMP. This chemical, cGMP, increases blood flow by relaxing the smooth muscle in the corpus cavernosum in the penis. Consequently, the blood vessels in the penis are widened, which allows more blood to flow into it.

Once PDE5 is blocked, cGMP is no longer broken down, which allows blood flow to maximise. As a result, more blood enters the penis, which causes an erection. Please note that this medication will not cause unwanted erections. It will only make it easier to become aroused in circumstances where you are mentally or physically stimulated. Without mental or physical stimulation, sildenafil will not work.

Sildenafil Dosage & Strengths

Sildenafil is a versatile sexual dysfunction medication that is available in a variety of different dosages and strengths. You can buy it in a variety of different forms right here too. Some of the different products that we have available are:

  • Sildenafil 25 mg - This is the lowest dose available. It is recommended for the mildest forms of sexual dysfunction, or for people who should not be taking higher doses of the medication. These people include the elderly, who can be more sensitive to side effects, those who are taking other medications that may impact the effects of sildenafil, and those with impaired organ function.
  • Sildenafil 50 mg -This is the standard starting dose for many who suffer from sexual dysfunction, or used by those in the above groups, who may have taken the 25 mg dose but found it ineffective.
  • Sildenafil 100 mg - This is the most popular dose and is the same dosage that is used in Viagra. It is used by healthy men and should be more than enough to be able to deal with moderate sexual dysfunction.
  • Sildenafil 150 mg - This is for more severe expressions of sexual dysfunction, where the 100 mg dose has not been sufficient.
  • Sildenafil 200 mg - This is the strongest dose available. It is for those who suffer from extreme sexual dysfunction, where all other products have not been effective enough. It should only be used by those who do not suffer from health conditions that may be impacted by taking this medication.

In addition to the above dosages, which are all typically available in the hard tablet format, we also have it available in other forms too, such as:

  • Sildenafil soft tablets - Available in a softer form than the typical hard tablets, these are generally available in 100 mg doses.
  • Sildenafil jelly - Sold in a flavoured jelly form in a sachet, this product also is usually sold in a 100 mg form.

Finally, there are also dual action medications available, that contain sildenafil to treat sexual dysfunction, as well as an additional product included in the medication to treat premature ejaculation. These typically contain 100 mg of sildenafil, and the appropriate dose of the premature ejaculation medication.

How Sildenafil Product Be Consumed

Sildenafil medications should be consumed differently depending on the product you are using. For hard tablets, you should swallow the medication whole with a glass of water. If desired, you can eat a light snack prior to consumption, but not a heavy meal rich in fats. This is because this medication is unable to be processed in the body until the large meal is processed first, which can delay how long it takes for the medication to start working.

For soft tablets, it is recommended that you place a tablet under your tongue and suck it, in order for the medication to be absorbed sublingually. This method helps the medication to be absorbed quicker than with a normal hard tablet. For sildenafil jelly, it is recommended that you squeeze the contents onto a spoon, or directly into your mouth. This can then be swallowed. Please note that neither soft tablets nor jelly needs to be consumed with water.

Sildenafil Duration of Action

Sildenafil has a general amount of time it is said to last, which can differ depending on the person taking it, dependent on weight, age, and organ function. In general, it is said that the hard tablets start to work within 30 to 60 minutes, and last for around 4 to 6 hours. Sildenafil soft tablets take a shorter amount of time to start working, because of the sublingual method of administration.

After placing the soft tablet under your tongue, you should find the effects start working after 20 to 30 minutes. After that, the strongest effects last for around 4 to 5 hours, slightly shorter than the duration of action of hard tablets. Sildenafil jelly is much the same as soft tablets, with the effects kicking in within 20 to 30 minutes and the strongest effects lasting for 4 to 5 hours. All forms will still be active in the bloodstream for upwards of 24 hours, however.

Is Sildenafil Safe for Everyone?

Sildenafil is considered extremely safe - it is the active ingredient in Viagra, which was the first sexual dysfunction medication and is still the most popular. If it were not completely safe for human consumption, it would have been discontinued before now. Sildenafil is not only the active ingredient in Viagra, however. It is also used in numerous generic medications, which are developed and licensed following the Pfizer patent expiry on the active ingredient. These generic medications are then approved by the Food and Drug Administration under their generic drug program.

There are certain people and scenarios in which people should not take this medication. These are known as contraindications. Some of the contraindications for sildenafil are:

  • People who are taking nitrates. Whether it be as part of a heart medication you are taking or taking nitrates as a recreational drug such as "poppers", it is considered dangerous to take nitrates alongside PDE5 inhibitors. This is because the combination of the two can lower blood pressure levels to an unsafe point.
  • People who drink grapefruit juice. Eating grapefruit or drinking too much of the juice is considered potentially dangerous when taking sildenafil. This is because grapefruit can increase the concentration of the medication in the body, resulting in an increased likelihood of experiencing side effects.

Are there Any Sildenafil Side Effects?

There are no medications in the world that do not have some kind of side effect associated with them. As such, it is important to be aware of them before you take any medication. Fortunately, sildenafil side effects are considered very mild compared to other medications. Some of the more common side effects that can be experienced are:

  • Headaches - one of the most common side effects, this can easily be treated with over-the-counter medication, such as paracetamol.
  • Vision changes - some people report altered vision after taking this medication, which can result in a blue tinge being present. This will disappear naturally after a short time.

Again, the above list is not all the side effects that can occur, only just the most common. For a full list, please refer to the manufacturers guide, the leaflet in the medication package, or by consulting a medical professional.

Why do People Buy Sildenafil Online?

There are multiple reasons why people look to buy sildenafil online instead of in person. Firstly, it is impossible to be able to buy these generic medications in shops. The only places that these generic medications can be bought are online. This means that there are only a few branded medications that can be bought in person, namely Viagra. This is an issue for several reasons. Firstly, Viagra is only available in a hard tablet format, so for those who have difficulty swallowing hard tablets, they do not have an alternative to help them treat their sexual dysfunction.

Furthermore, branded options are only available in 25 mg, 50 mg, and 100 mg doses, so if you are looking for something stronger, if your sexual dysfunction has not responded to these doses, you are out of luck. Online pharmacies such as ours sell generic medications that are also available in 150 mg and 200 mg doses, meaning that you can treat your sexual dysfunction, regardless of the severity.
