Sildenafil is part of a group of drugs known as PDE5 inhibitors. It works by relaxing the arteries at the base of the penis, which increases blood flow to the penis and results in an erection firm enough for fulfilling sex. The active ingredient – sildenafil – is also sold under the brand name of Viagra UK, and the two tablets work in exactly the same way.
For sildenafil to work, arousal is still required – the stimulation releases hormones, which cause changes in the way blood flows through the penis.
BUY SILDENAFIL 25mg 50mg 100mg
You can buy sildenafil in strengths of 25mg, 50mg, and 100mg, but you must only take one every 24 hours. For maximum effectiveness, these tablets are best taken on an empty stomach with water. We recommend taking one tablet an hour before sex for results within 30 to 60 minutes.
These tablets are safe for most healthy men, but they may be unsuitable for people with conditions such as high or low blood pressure, certain heart problems, and liver or kidney disease. Before you buy sildenafil online, you will need to complete an online consultation form to check that this medication is suitable for you.
We recommend reading the patient information leaflet before you start treatment.
What is Sildenafil?
While most people are familiar with the branded erectile dysfunction product Viagra that was brought to market by Pfizer, fewer people are aware of the generic medication sildenafil. The term sildenafil actually relates to the active ingredient in the drug, which serves to aid blood flow to the penis during arousal. So, if you have been searching for Viagra tablets for men, it’s important to note that sildenafil is a medically identical product that is much cheaper – and has been available from many different pharmaceutical companies.
A safe, cost-effective alternative to buying Viagra online
Here at PostMyMeds we offer prescriptions for sildenafil 25mg, sildenafil 50mg and sildenafil 100mg. The required strength of medication will typically be determined by the responses provided in your online questionnaire and the requirements determined by our highly qualified and fully-registered prescribers. However, most common starting dose for patients is sildenafil 50mg tablets. While there are different types of Viagra and different brand names for sildenafil medication, there is no difference in medication strength when the dosage is the same.
If you’ve been wondering where to buy Viagra online then you have come to the right place. Not only is our online service quick and exceptionally discreet, our prescription sildenafil is a cheaper option than the branded alternative.
What causes erectile dysfunction?
There can be many different causes of erectile dysfunction, ranging from physical conditions to mental issues. There is no single factor that leads to erectile dysfunction (ED) in everyone. What we can say, however, is that the result is a lack of circulation to the penis, either due to impaired blood flow or the body’s failure to respond to perceived arousal. It is also worth noting that instances of ED increase with age.
Factors that are known to impair circulation include obesity, smoking and lack of exercise. Other issues like diabetes are also closely associated with ED.
It is also important to note that the effects of erectile dysfunction are not just physical, particularly if sufferers find themselves dealing with the issue over a sustained period of time. When left without treatment, a condition like erectile dysfunction can quickly lead to psychological and emotional issues including performance anxiety and even depression. It goes without saying that these problems will ultimately have a negative effect on relationships.
Left untreated, the issue of performance anxiety can often become worse and the fear of being unable to “perform” can result in a vicious cycle of worsening erectile dysfunction. One of the benefits of sildenafil is that it supports a stronger, sustained erection that, in many cases, results in greater sexual confidence and a corresponding improvement to self-esteem.
These improvements may, in turn, alleviate anxiety or even depression if ED has been the root cause of this issue. However, it is important to note that any psychological concerns or relationship concerns should be shared with your partner or a reputable professional such as your GP.
How common is erectile dysfunction?
Erectile dysfunction is surprisingly common and affects thousands of men each year. In fact, around half of men in the UK are thought to experience erectile dysfunction at some point over the course of their lives. An estimated 1 in 10 experience ED for a prolonged or significant period.
Older adults are more likely to suffer from erectile dysfunction with 70 per cent of men over 70 experiencing impotence. Estimates suggest that 50 per cent of men over 40 also live with the condition. Nevertheless, almost 25% of ED treatment enquiries are made by men under the age of 40.
Drugs that are not compatible with Sildenafil
In completing your online questionnaire to access a sildenafil prescription you will be asked a number of questions relating to your medical history, state of health and any other medications you are taking. This is important because sildenafil is not suitable for use alongside some other drugs. This includes other PDE-5 inhibitors.
It is also advised that should you take any other ED medications such as Levitra, Spedra or Priligy that you leave 24-48 hours between treatments.
Blood pressure medications are known to interact with sildenafil, which is why you should seek medical advice before taking ED medication at the same time as alpha-blockers such as Tamsulosin and Doxazosin or beta-blockers such as Metoprolol. Other medications that interact with sildenafil include ACE inhibitors such as Lisinopril, ARBs such as Losartan and CCBs such as Amlodipine.
Sildenafil should not be used in conjunction with nitrates that lower blood pressure. Nitrates as blood pressure medications are often used in order to prevent angina. However, nitrates also feature in recreational drugs such as poppers, which contain amyl nitrate.
Viagra is not known to interact with statin drugs – used to treat raised cholesterol – such as Lipitor or Zocor. However, high cholesterol is closely associated with ED.
Can Sildenafil be taken alongside herbal ED remedies?
Ashwagandha is an herb that is increasingly being used to treat erectile dysfunction in men. It has not been proven that ashwagandha is effective as a form of medication or herbal remedy but it is believed that it has beneficial properties in easing symptoms including stress and anxiety.
There is currently no known interaction between sildenafil and ashwagandha. However, if you have any adverse reaction to taking both at the same time, it is important to stop immediately and consult your doctor.
