Is it okay for men to take Viagra?

Viagra from Pfizer is the oldest and most prescribed drug for treating erection problems. How does Viagra work? It is a blue pill that works within 30-45 minutes. After ingestion, the man has an easier time getting an erection. This medicine works for up to 8 hours. If you have eaten fatty foods in connection with taking Viagra, the effect may be delayed or reduced. Why do so many choose Viagra? Viagra ( sildenafil ) is the most well-known drug and has been on the market for a long time, but not necessarily the most suitable treatment for everyone. For men who eat fatty foods, other drugs may be more suitable, as this reduces or delays the effect of sildenafil. Who should not use Viagra? You should not buy Viagra if you have heart or vascular problems or are being treated with nitrates. There may also be other situations where you should avoid buying Viagra. Discuss with a physician for good advice that is consistent with your own health situation. Where to buy Viagra online? There are many different online pharmacies and clinics that sell Viagra online. But it is important to be careful, as many websites are not serious. In order to sell Viagra online, the pharmacy must have a doctor who asks some control questions and approves the prescription.

Levitra ( vardenafil ) from Bayer is a popular potency pill that continues to gain ground. The biggest benefits are that Levitra lasts for up to 36 hours and you get the full effect, even if you ate fatty foods just before taking a pill. Levitra can also be taken by those who have high blood pressure or diabetes. The result comes quickly, usually within 20 minutes. How does Levitra work? It is a round, orange pill that works within 15-45 minutes. After ingestion, the man has an easier time getting an erection. Vardenafil normally works for between 8-12 hours. Note that the effect is felt when you are sexually aroused, which is required for you to get an erection with Levitra. Many men also experience that they become more sexually tolerant when taking Levitra. Why do so many choose Levitra? Levitra is starting to gain acceptance among doctors as an alternative to Viagra and Cialis . Many men find it easy to take a pill that lasts a little longer and works well for many different types of diseases. Finally, vardenafil is a drug that seems to cause fewer side effects than several other potency pills, ie. no headache or chest pain when using this treatment. Who should not use Levitra? You should not buy Levitra if you have heart or vascular problems, are over 75 years of age or are being treated with nitrates. Do not drink grapefruit juice while using Levitra. There may also be other situations where you should avoid using or buying Levitra. Note: You must always talk to a doctor to make sure this potency pill is right for you. Where can you buy Levitra online? There are many different Internet pharmacies and clinics that sell Levitra online.

Cialis ( tadalafil ) is one of the fastest growing drug for treating potency problems. The biggest benefits are that Cialis lasts for up to 36 hours and you get a good effect, even if you ate fatty foods just before taking a pill. How does Cialis work? It is a yellow pill that works within 20-45 minutes. After ingestion, the man has an easier time getting an erection. Tadalafil normally works for between 24-36 hours. Note that working does not mean that you have a constant erection for such a long time, but rather that you get a hard erection easier. Many men also find that they become more resilient when taking Cialis. Why do so many choose Cialis? 'Weekend pill' as it is also called has been on the market for quite a few years now and has started to gain acceptance among doctors as an alternative to Viagra. For men who often eat fairly fatty foods, Cialis can be a good alternative, as it works just as well even after consuming foods high in fat. Many men find it easy to take a pill that lasts a full 36 hours, which means that they can take lower monthly doses of medication. Who should not use Viagra? You should not buy Cialis if you have cardiovascular problems or are being treated with nitrates. There may also be other situations where you should avoid buying Cialis. Note: You must always discuss with a doctor to ensure that this potency pill is suitable for you. Intake of inappropriate drugs can, in the worst case, lead to death. Where can you buy Cialis online? There are many different online pharmacies and clinics that sell Viagra online.

Viagra ( sildenafil) relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body. Viagra is used to treat erectile dysfunction (impotence) in men. Another brand of sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. An FDA investigation found that more than one-third of "dietary supplements" sold for ED actually contained prescription drugs, including sildenafil, the medicine in Viagra. Some ED drugs sold online contained entirely different medicines, such as the antibiotic metronidazole and the fertility drug clomiphene.

What’s the best Viagra for men? In truth, there’s only one Viagra. That’s Pfizer’s drug powered by the active ingredient Sildenafil. It comes in 25mg, 50mg, and 100mg doses.

Priligy is the only prescription drug available to treat premature ejaculation. With Priligy, men who 'come too fast' can get help to 'endure' longer. The pill is taken 1-3 hours before sexual activity and counteracts premature ejaculation. Clinical trials have shown that Priligy, on average, prolonged ejaculation by a factor of three. Instead of, as before, coming within a minute, the Middle Ages became the subjects who took Priligy over three and a half minutes. Priligy can cause a number of side effects and should not be taken with a variety of other medicines. This medicine is available for prescription at various pharmacies throughout Sweden and at several online pharmacies.

Some men might find that the best treatment for erectile dysfunction (ED) is generic Sildenafil, the generic unbranded form of Viagra. This tends to be more affordable, but it has the same safety profile and efficacy as the branded drug — and is available in the same dosages.

Other ED treatments include Cialis, which is powered by the active ingredient Tadalafil. This works in a similar way to Viagra, but its effects last for longer. In the search for the best ED medication out there, many men will find this a preferable option.

Treating Erectile Dysfunction

Early ejaculation - Premature ejaculation, involuntary ejaculation or premature ejaculation as it is also called is an erection problem that is more common than many people think. Until just over two years ago, there was no treatment for men who squirt faster than they want. But fortunately, today you can relatively easily solve problems with early ejaculation. The solution is called Priligy , a prescription drug with relatively few side effects that can be bought at pharmacies and online pharmacies. When you buy online, you must first complete a short hearing about your health problems, after which a doctor confirms that Priligy is suitable for you.

While erectile dysfunction (ED) can affect all men, there are now many different medical and non-medical options out there to treat it — from exercise to surgical intervention.

However, one of the easiest, most effective, and best-known treatments for erection problems is Viagra. It’s the ED drug made by the pharmaceutical company, Pfizer, that’s powered by the active ingredient known as Sildenafil.

Here, we’ll introduce you to Viagra, and the alternative unbranded version, Sildenafil. But what’s the best Viagra for men? That’s not for us to decide. Every man’s body is different, and you’ll only know if a low, medium, or high dosage works best once you’ve tried it. 

What is Viagra?

Viagra is probably the best-known treatment for erectile dysfunction available. Recognisable as a ‘little blue pill’, it’s trusted by millions of men around the world to help them achieve and maintain an erection.

It works thanks to its active ingredient, Sildenafil citrate. This is a drug known as a PDE5 inhibitor. Its job is to target an enzyme, phosphodiesterase 5 (PDE5), that’s responsible for smooth muscle contraction in the penis. Sildenafil inhibits the function of this enzyme and allows more blood to flow to where it’s needed — boosting your chances of getting and keeping an erection.

Thanks to Sildenafil, Viagra is highly effective in treating erectile dysfunction. With a 100mg dose, studies have found that treatment improves erections in over 80% of men.

What’s the Best Viagra for Men?

If we’re totally honest, there is no best Viagra for men, for a simple reason. All Viagra is the same — powered by the same active ingredient, Sildenafil. The different types of Viagra only differ by strength. And so, while you’ll find more or less potent versions of Viagra, it all works in the same way.

There are three different doses of Viagra. The one that’s best for you will depend on your situation.

  • 50mg (Viagra Connect). The standard dose, the 50mg Viagra is sold over the counter as Viagra Connect. 74% of men who use the 50mg dose can achieve an erection, according to studies.
  • 100mg. The higher dose of Viagra is the 100mg pill. It tends to be recommended to those who have tried Viagra Connect but have not seen results.
  • 25mg. The lower dose, meanwhile, is for those who have not tolerated the higher doses well. With a lower dose, you’re less likely to experience side effects.

When it comes to medicine, ‘best’ is only a matter of what works for you. And Viagra is no exception.

Erections aren’t always easy for millions of men in the UK. It’s no big deal. Choose from highly effective, clinically proven solutions.

Side Effects?

All medicines have side effects. However, these can differ from one man to the next. When considering which Viagra is best, you’ll need to assess these too.

So, if you regularly experience any of the following when taking Viagra, a lower dose might be preferable:

  • Headache
  • Chest pain or angina (caused by not enough oxygen reaching your heart muscle)
  • Changes to or loss of vision
  • Indigestion
  • Stuffy nose or congestion
  • Priapism — one of the more serious side effects of Viagra. Priapism is a painful erection that won’t go away. In this case, seek medical advice immediately.

Note. Both the UK NHS and the US FDA recommend that you do not take Viagra if you have heart disease or are taking drugs for high blood pressure (such as Riociguat). If you are taking nitrates or alpha-blockers, you’ll need to tell the pharmacist before they can sell you Viagra, in any form.

Other Options for the Treatment of Erectile Dysfunction

You should know that Viagra is not your only option when it comes to treating ED. The best ED treatment out there for you might be something completely different. Here are some alternatives.

Unbranded Sildenafil

Sildenafil is the active ingredient that powers Viagra. However, the drug itself is available without the famous brand name. It’s just as effective, safe, and easy to use. You just pay less for the generic version.

Available in 25mg, 50mg, and 100mg doses just like Viagra, generic Sildenafil delivers the same results at a fraction of the cost. If not the best Viagra, it’s up there with the best ED treatments out there.

Tadalafil – or Cialis

An alternative treatment for ED is Cialis, a medicine containing the active agent, Tadalafil. What’s the difference between Cialis and Viagra? You can get the full picture here. Put simply, Cialis lasts for longer. If Viagra is out of your system after 4 hours, Cialis works for 36 hours. And that gives everything a bit more flexibility.

Both Tadalafil and Sildenafil are PDE5 inhibitors, and research has shown that there is little difference between their rates of effectiveness. Yet, studies suggest that side effects with Tadalafil are slightly less common.

Vardenafil (Levitra) or Avanafil (Stendra)

Other PDE5 inhibitors include Vardenafil, which is often sold as Levitra, and Avanafil (Stendra). While they work in similar ways to Tadalafil and Sildenafil, studies have shown them to be slightly less effective.

You might find that these are good to try if you‘ve had limited success with the more effective alternatives. Remember: every man is different.


The generic unbranded form of Viagra

It’s the active ingredient in Viagra and clinically proven to be highly effective by increasing blood flow into the penis.

Key Takeaways

What’s the best Viagra for men? That will depend entirely on you. While most men start with the 50mg option — known as Viagra Connect — others will find that the 25mg or 100mg alternatives are more effective, or may help reduce annoying side effects.

While Viagra is the best-known ED treatment, though, it doesn’t mean it’s the best. Instead, you might find that generic Sildenafil, or Cialis, better suits your needs.
