How Does Viagra Work & Is It Effective?

Many people take medication every single day for a whole host of reasons; to lower blood pressure, pain relief, or in the case of vitamins and other related supplements, to improve and maintain their health, or to modify their quality of life such as mental performance. Indeed, it is estimated that around 7 out of 10 of us now take medication at least once a week, but what are we really putting into our body? How does it work?

These are the kind of questions very few people ask before taking medication and generally, that is fine and very understandable (ask someone in grocers how paracetamol works at the checkout and it can be presumed they will not be able to tell you). This is generally not a cause for concern for many us but when self-medicating it is crucial to consult your GP or pharmacist before taking any medication. This is for a range of reasons, primarily, patient safety; many people are on more than one type of medication and taking another medicine in combination can be dangerous due to potential interactions between the two medications. It is the principles of how the medication works which governs their safety and effectiveness.

Unfortunately, due to poor public awareness of this condition and a degree of social stigma, it is a problem very few men feel comfortable talking about let alone going to seek help for. Indeed, people falsely believe that sufferers of ED can somehow be less masculine in nature. However, this is not the case! In fact, this is generally a relatively common problem as the NHS state that ED affects almost half of men between 40 and 70 years of age. Furthermore, approximately 30 million American men suffer from a degree of impotence. So men should know they are in no way alone in this battle!

What can you do? The good news is that erectile dysfunction is a treatable condition and a number of treatment options are available such as lifestyle changes doctorand medications like Viagra which is suitable for men over the age of eighteen. It comes as a blue diamond shaped tablet with writing indents on both sides of the tablet; one side contains the strength of the tablet and on the other side it has ‘Pfizer’, which is the company which produce Viagra. It comes in three strengths; 25mg, 50mg and 100mg. It is available on prescription following a consultation with an appropriate prescriber such as a doctor or pharmacist to assess the suitability of the treatment. It is also important to ensure that the cause of ED is not concealing any other health conditions such as heart disease. It can also be beneficial as the professional will also be able to signpost patients to other services such as counselling for cases where mental issues may be the cause of the problem.

Product Description

How does Viagra and Sildenafil work?

Viagra (Sildenafil) helps men to get and maintain an erection when sexually stimulated and/or excited. The medicine relaxes the blood vessels in the penis which results in more blood flowing to the penis when you are sexually excited.

How do I take it?

You should take Viagra (Sildenafil) approximately 1 hour before planning to have intercourse. Within a window of between 30 minutes and 4 hours after you take the medicine, it will be easier to keep and maintain an erection when you are sexually excited. If you take this medicine after a meal with a high fat content it may take a little longer to start working. This medicine will only work when you are sexually excited. You won’t get an erection just by taking Viagra (Sildenafil).

Dosage

The standard recommended dose for Viagra (Sildenafil) is 50mg and this will be suitable for most people.  If this dose is not effective, you can try 100mg and if 50mg gives you side effects you can also reduce the dose to 25mg tablets.

You must not take more than 100mg daily of Sildenafil/ Viagra. Clinical trials have been conducted in patients taking up to 200mg sildenafil and it was found that ‘doses of 200mg did not result in increased efficacy but did increase the incidence of adverse reactions (headache, flushing, dizziness, dyspepsia, nasal congestion, and altered vision).’

In addition, in patients taking more than 100mg daily, there have been reports of rhabdomyolysis (a breakdown in skeletal muscle tissue the byproducts of which can lead to kidney failure), visual perception changes, vertebral artery dissection (a tear in the artery supplying blood to the brain), heart attacks and aggressive behaviour.

If the 100mg strength doesn’t work for you, there may be alternatives you can try and we recommend that you call us for a free consultation with our pharmacist or doctor to discuss any underlying conditions you may have. We recommend that all men taking medicine for erectile dysfunction have regular tests for blood pressure, cholesterol, diabetes and hormone imbalances. For instance, it may be that by fixing a hormone imbalance such as testosterone, your Viagra medication will be even more effective.

In addition, drug manufacturers do not advise patients to split tablets in half to get the correct dosage as they cannot guarantee that the active ingredient will be distributed evenly throughout the tablet.  For instance, if you cut a 100mg tablet in two, you may find that you get 80mg in one half of the tablet and 20mg in the other half leading to either an overdose (increased risk of side effects) or a suboptimal dose (the medication may not work).

It is important that you choose the correct dose for you. If you wish to talk to our pharmacist or doctor about this, please contact us in the pharmacy on 01625 460621 or email [email protected]

Side Effects

Viagra (Sildenafil) is normally well tolerated, however, side effects can include:

  • Headache
  • Dizziness
  • Nausea

Side effects normally subside after a few hours, however, if you experience a prolonged or painful erection (longer than 4 hours), then you must contact your doctor immediately.

Drug interactions

There are a number of medicines which interact with Sildenafil/ Viagra. For an exhaustive list please see the patient information leaflet (see section below) or call us in the pharmacy to discuss your specific situation. The main drug interactions are listed here:

In relation to how this medication works; and is Viagra effective, it is known as a phosphodiesterase inhibitor and it works by maintaining levels of messenger cyclic guanosine monophosphate which relaxes smooth muscle allowing a penis to become erect when sexually stimulated. This process occurs by arteries in the penis dilating, thereby, increasing blood flow. Blood perfusion into the erectile tissues aids this mechanism.

Viagra is best taken on an empty stomach and takes approximately one hour to become effective and the effects can last for up to six hours. The effects of the medication are slower in action following the consumption of a large meal. It is important to always take the medication as directed by the prescriber. It should also be noted that the amount of time Viagra takes to work varies from person to person. The recommended starting dose is 50mg once daily and should be swallowed whole with a large glass of water. If patients feel that the dose is not suitable in that it is too strong or too weak they should consult their pharmacist or doctor. It should also be noted that Viagra and other similar medication will only help to get an erection if you are sexually stimulated.

Sildenafil-100-4It should be noted that Sildenafil and other related products are not listed for NHS prescribing in the BNF, exemptions may apply such as cancer patients or when the prescriber feels that the condition is causing the patient significant distress or a marketed effect on interpersonal relationships. Your healthcare provider will be able to advise you on this matter.

Now an important question, which many men will wonder, how effective is this medication?

Firstly the obvious should be stated; the effectiveness of Viagra is greatest when the appropriate dose is taken along with the appropriate dosage recommendations such as an empty stomach. This is the information the pharmacist can provide patients with. Similar information is included in the Patient Information Leaflet included in the medicines box.

viagra 100mgFurthermore, for many men, this is a ‘wonder’ pill which can greatly improve quality of life among other benefits and so it is no wonder that Viagra manufacturers Pfizer have gross profits of millions of dollars. Indeed, since the approval of Viagra in 1998, Sildenafil has been effective in over 100 clinical trials involving over 8000 men with erectile dysfunction. Sildenafil is the first line therapy in the treatment of erectile dysfunction compared to other drugs of the same pharmacological class, such as Tadalafil/Cialis and Avanafil/Spedra making it the first choice for prescribers.

So if you are thinking of trying Viagra or other related medication, it is easier now than ever before. Indeed, this medication can be delivered discreetly to your home following an online consultation with a UK based doctor at Assured Pharmacy. Quality is guaranteed and safety is much greater than self-medicating at home such as buying online products via illegitimate websites in which many of the medicines may be counterfeited and may not be suitable for everyone.

In conclusion, Viagra is a great solution to male impotence and has proven to be very effective in a majority of users. It is also becoming more convenient and discreet to get safe and reliable treatment through services such as those provided by Assured Pharmacy, so don’t delay in seeking help and advice for this very treatable and common condition.
