What Is Sildenafil?

Sildenafil is the active ingredient found in Erectile Dysfunction medication Viagra®.

Sildenafil works by helping men who are sexually stimulated to have harder and longer-lasting erections. Viagra got FDA approved in 1998, and its original patent expired in 2020, putting an end to its exclusivity on Sildenafil. Since then, many branded and non-branded generic versions of Sildenafil have hit the market. However, brands like BlueChew created their very own Sildenafil compound, giving men a chewable and more affordable option for better sex.
Sildenafil is a prescription drug that has to be taken orally. It can be ingested with or without food. The medication kicks in within 30 to 60 minutes, and its action can last between 4 to 6 hours.
Under the brand name Revatio, Sildenafil is FDA-approved to treat pulmonary arterial hypertension (PAH). The medicine works to decrease blood pressure in the lungs and improve the capacity to exercise.

Who Can Use Sildenafil?

Any man over 18 with a valid prescription can use Sildenafil.

Sildenafil might not be for you if you’ve had an allergic reaction to any other ED medication, such as Tadalafil or Vardenafil, or if you’ve had a stroke or heart attack recently.

How to Use sildenafil

You can take Sildenafil up to four hours before sex because the medication itself stays active in your metabolism for 4 to 6 hours and will only be triggered when you are excited.

With only one tablet a day, your confidence will significantly improve, and you can have a safer and more pleasurable sex experience.

How Sildenafil Works

Sildenafil is an oral drug that will temporarily lower the blood pressure in your metabolism to facilitate increased blood flow to the penis. But to fully grasp how the med works, you must know how erections work.

Being turned on creates a chain reaction from the brain to the penis until intercourse is complete. It goes from sexual stimulation to the brain releasing nitrate oxide. Then nitrate oxide produces cyclic guanosine monophosphate (cGMP), an enzyme that will be released into the penis, allowing the blood vessels there to widen and increase the blood flow. And then, another enzyme, the phosphodiesterase-5 (PDE5), enters the arena to bring the penis back to its original state. It’s PDE5 that will disgorge the penis and make all the trapped blood return to other parts of the body.

What Is the Proper sildenafil Dosage for ED?

Your recommended dose will depend on your medical history and lifestyle. The lowest dose possible is 25 mg per tablet, and the highest one is 100 mg. With its different plans, BlueChew offers Sildenafil in 30 mg or 45 mg tablets.

Always follow your doctor or pharmacist’s instructions carefully to avoid any serious side effects.

What Are the Benefits of Using sildenafil for Erectile Dysfunction?

1. Sildenafil Improves Blood Flow

For 30 million men in the US and 150 million worldwide, getting and keeping an erection at times can be a challenge. Your body is a complex organism, and there are many reasons, emotional and physiological, that can explain ED. The most basic one is limited blood flow to the penis.

Sildenafil works by relaxing the muscles inside the blood vessels and allowing them to fill and entrap blood in the corpus cavernosum. These are the sponge-like tissue chambers in the penis that facilitate your erections, making it possible for the penis to be hard and engorged with blood during intercourse.

2. Sildenafil Works as an Erection Booster

Let’s be honest, ED pills earned the nickname “boner pills” a long time ago, but that’s not exactly accurate. Some men worry that taking Sildenafil will cause a spontaneous erection, but that is not actually true. The active ingredient only makes it easier for blood to flow to your penis and remain there while erect. The keyword here is easier. So if you are not aroused, you will not get an unwanted erection. Arousal and increased blood flow work together to help you have a more complete sexual experience.

3. Sildenafil Improves Your Confidence in Bed

Many men experience some form of erectile dysfunction for a variety of reasons. Stress and anxiety can definitely affect a man’s hard-ons, and trouble getting satisfying erections can become an important source of stress and anxiety. To escape the vicious cycle, Sildenafil can be taken before sex to relax you and your blood vessels, facilitating a higher blood flow to the penis.

But that’s not the only advantage. Performance anxiety is another factor that can negatively affect a man’s erections. With Sildenafil, you get a confidence boost from firmer erections, which relieves the pressure and makes sex more enjoyable.

If you’re feeling self-conscious about your performance, talk with our medical team AND your partner. Opening up is a good way to alleviate your stress and reassure your partner, who could interpret your ED symptoms as a lack of attraction. Just having that conversation can improve your sex life immensely.

Both Sildenafil and Tadalafil are PED5 inhibitors that increase blood flow to the penis. They both can take effect in as little as in 30 minutes help men achieve stronger and firmer erections. They also have similar potential side effects.

Sildenafil is the active ingredient found in Viagra, the first drug ever approved to treat ED symptoms. Unlike Tadalafil, Sildenafil is prescribed for occasional use, and its action only lasts between 4 to 6 hours.

Where Can I Buy Sildenafil?

With a valid prescription, you can get Sildenafil at any drugstore. But there’s an easier and more convenient option. BlueChew developed a telemedicine platform specifically designed to help men who experience ED symptoms. The brand also came up with chewable versions of Sildenafil, Vardenafil, and Tadalafil that will grant you the same benefits as any other ED medication.

Instead of booking an appointment with a urologist and dragging yourself to a specialized clinic, simply fill out a medical form and get it reviewed by a licensed medical provider. Not only can you get your prescription fully online, but your chewable tablets can be delivered to your doorstep.

Based on your prescription, you can choose the best plan for your sex life. Of course, nothing is set in stone. If the plan you start with doesn’t work for you, you can still change it online on your BlueChew portal.
