What is Sildenafil
Used in the treatment of erectile dysfunction (ED), Sildenafil belongs to a group of medicines called PDE5 inhibitors. These drugs prevent an enzyme called phosphodiesterase type-5 from working too fast. In turn, this makes it easier to get and maintain an erection during sexual stimulation. Note that any patients suffering from cardiovascular disease should consult a physician before using this treatment or related medicines.
Why choose Sildenafil?
ED can be a distressing problem, and it may have a negative impact on your self-esteem and your relationships. Sildenafil offers reliable and effective treatment. It contains the same active ingredient as Viagra (sildenafil citrate), but it is a cheaper alternative. The drug is effective within one hour, and its positive effects can last for up to six hours.

How effective is Sildenafil
The dose used in each patient's situation can ensure greater or less effectiveness depending on what someone desires to achieve from their treatment. For example, some may prefer to be able to use one tablet daily, whereas others may prefer or require a lower dose, such as those having more side effects from the treatment or an older patient or those with poor underlying health issues. Whatever your require, there are different doses of the product which can be used to benefit your personal situation.
It has been clearly shown to be effective for patients with severe ED, and as such, it also appears from studies that Sildenafil also improves the quality of the patient's relationship with their sexual partner overall.
How does Sildenafil work?
The medicine works by relaxing the muscles in the veins that carry blood to the penis by preventing the action of a certain natural chemical called phosphodiesterase type-5. By doing this, it promotes increased blood flow, making it possible to get an erection during sexual activity. Contrary to popular belief, the treatment does not cause spontaneous erections or have any effect on your sexual desire; instead, you must be sexually aroused to get an erection using Sildenafil.
It is important to be aware that PDE5 inhibitors do not treat the underlying causes of ED, which can include physical problems such as diabetes and high blood pressure and psychological issues like anxiety and depression. Because of this, it is important to seek medical advice to find out why you are experiencing ED.
What dose should I choose?
The treatment comes in tablet form, and you should never take more than one within a 24-hour period.
There are three available dosages, 25mg, 50mg and 100mg, and whilst the higher dose can increase the effectiveness of the treatment, the lower dose can incur fewer side effects.
For further information on dosages, you can speak to your doctor or consult one of our knowledgeable healthcare professionals at Click Pharmacy.
How should I take Sildenafil?
The drug usually works best when taken an hour before sexual activity though it can be taken anywhere between 4 hours and 30 minutes before intercourse. It is most effective when consumed on an empty stomach and without alcohol, and certainly, if you do eat prior to taking it, then bear in mind that a high-fat meal will negatively affect its ability to work. Once taken, it can carry on working for between four and six hours.
What does Sildenafil contain?
The active ingredient is Sildenafil citrate in doses of 25mg, 50mg and 100mg per tablet.
The inactive ingredients are:
- microcrystalline cellulose
- anhydrous dibasic calcium phosphate
- croscarmellose sodium
- magnesium stearate
- titanium dioxide
- lactose monohydrate
Can you drink alcohol with Sildenafil?
Alcohol decreases the amount of blood which will remain in your penis, making it more difficult for you to achieve an erection. It can also be dangerous to take Sildenafil and alcohol as both products lower your blood pressure meaning that you could end up feeling dizzy and faint. As such, if you are taking Sildenafil for ED, then it is best to avoid alcohol as it will not help to improve your sexual performance.
Can I take other ED medications with Sildenafil
It is important to tell your GP or Click Pharmacy doctor if you are taking any other prescription or non-prescription medications, including vitamins, supplements and herbal products such as St John’s Wart. This is because certain drugs can interact with Sildenafil making it either ineffective or dangerous to your health.
Can I take Sildenafil, Levitra, or Cialis at the same time?
No. Never combine erectile dysfunction treatments. The combination can cause severe side effects and can even lead to an overdose. If one treatment does not work, then take a gap of a few days before starting a new one.
Can I take Sildenafil with other prescription medicines?
You can take Sildenafil with almost all other prescription medicines. There are a few exceptions, like medications to treat angina. For instance, nitrates. This medicine is primarily used to treat heart disease. When it interacts with Sildenafil, it can cause a dangerous fall in blood pressure.
What is the difference between Sildenafil and Viagra?
In medical terms, Sildenafil and Viagra are the same things. Viagra is the brand name of Sildenafil. Sildenafil is the active ingredient in 'Viagra'. They are interchangeable and can be found in packs of 4 and 8 tablets. You can find both in strengths of 25mg, 50mg, and 100mg.
What should I do if Sildenafil does not work or stops working?
Sildenafil is a very effective medication. The same dose of Sildenafil remains effective for a long period of time. This is because the human body does not become used to the effects of Sildenafil, nor does it become immune to it. So, if you are facing a poor response from the medication, it may be due to the manner you are taking the pills. It is best to take the tablets on an empty stomach. First, try taking the dose again on a different occasion and observe the effects. If the tablet fails to help time after time, it is crucial to consult your GP as it may be an indicator of an underlying disease or the worsening of erectile dysfunction.
Can Sildenafil tablets be divided?
It depends. Unless your GP advises you to split the tablet, do not do it. There are some brands of Sildenafil tablets that can be cut or broken into two easily without any complications. This is because they are scored tablets. However, other brands of Sildenafil are un-scored. Such tablets can not be split into two as they shatter.
Can I get Sildenafil on the NHS?
Yes, you can get Sildenafil on the NHS. GPs or NHS healthcare providers can prescribe Sildenafil, although it is usually in a limited amount. There is a strict eligibility criterion that you need to pass first, too. Note that NHS prescription fees will apply.
Can I buy Sildenafil without a prescription?
Yes. You can purchase Sildenafil without a prescription in the UK. However, the strength is limited to 50 mg. Keep in mind that Sildenafil without a prescription is significantly more expensive.
How do I store Sildenafil tablets?
They should be stored in a closed container at room temperature in a safe place, away from direct exposure to sunlight or extreme temperatures.
Can I take Sildenafil Tablets if I take nitrates?
Medicines known as nitrate (often prescribed for chest infections and pains) can be dangerous if combined with Sildenafil Tablets. The combination often results in blood pressure levels to drastically drop.
If you take nitrates, you should avoid taking Sildenafil Tablets.
Can females take Sildenafil?
Sildenafil is not suitable for female use.
Can I take Sildenafil if I have a low blood pressure?
Sildenafil is not safe to take if you experience low blood pressure, have recently had a stroke or heart attack and have a serious heart or liver problem.
Can I drink alcohol while taking Sildenafil?
Drinking alcohol should be avoided as both alcohol and sildenafil lower blood pressure which could lead to extreme dizziness and feeling faint.
Why is Sildenafil cheaper than Viagra?
In 2013 Viagra lost its UK patent, meaning new and similar drugs were formulated. Sildenafil was one of the new drugs, so it is considerably cheaper despite it containing the same ingredients.
As with all medicines, there are potential side effects to consider. The most common include headaches, heartburn, flushed skin, nasal congestion, indigestion, nausea, vomiting and diarrhoea. Also, note that the treatment should never be taken with nitrates because it can cause a serious and potentially fatal drop in blood pressure.
Taking too much and overdosing can be highly dangerous and will not increase the desired effects of the treatment. But it can result in side effects such as chest pains, an irregular heart rate, nausea and priapism which is an erection which cannot subside. If left untreated, priapism can lead to permanent damage and future issues with achieving an erection. If this occurs, seek medical support right away.
For further information on these issues or if your treatment does not work satisfactorily, contact your GP or consult our specialists.
