Buying Sildenafil Tablets - What You Need To Know
What is Sildenafil?
Sildenafil is an oral medication that is routinely prescribed to treat erectile dysfunction. It is better known as being sold under the brand name, Viagra. However, as a generic rather than branded medication, it is usually much more affordable than its branded alternatives.
Erectile dysfunction occurs when it becomes difficult to get or maintain an erection that is rigid enough for sexual penetration. This can happen for many reasons, but health and lifestyle factors such as obesity, high blood pressure, smoking, excessive alcohol consumption and stress often contribute to episodes of erectile dysfunction.
Erectile dysfunction can also be caused by some medications like antidepressants, antihistamines, chemotherapy drugs and beta-blockers.
Sildenafil is also known as: Aronix, Liberize, Niaptra, Revatio, Grandipam, Viagra and others.
How Does Sildenafil Work?
To understand how sildenafil works, it helps to understand what happens when you get an erection. When you become sexually aroused, your brain sends signals to the muscles in your penis to relax. It does this by producing a chemical called cGMP. When this happens, the blood vessels in your penis fill with blood, causing it to get bigger and firmer and move away from the body. When you are no longer sexually aroused, or after ejaculation, the blood flows back out of the penis, causing it to soften again. For men with erectile dysfunction, it’s often the breakdown of cGMP by an enzyme called phosphodiesterase type 5 (PDE5) that leads to their inability to get or keep an erection.
Sildenafil works by blocking the action of this enzyme, enabling the blood vessels of the penis to relax and fill with blood, so that you may achieve an erection that’s firm enough for sexual satisfaction.
Sildenafil is also sometimes prescribed to treat a type of high blood pressure called pulmonary hypertension.
Important information: Sildenafil alone can’t cause an erection; you still need to be sexually aroused for it to work.
Sildenafil Doses
Sildenafil is available in different strengths. These range from 25mg to 100mg.
For erectile dysfunction, the usual recommended dose is 50mg. However, it can be increased to 100mg or decreased to 25mg depending on how effective it is for you. For example, if you take a 50mg dose, but you still aren’t able to achieve an erection firm enough for sex, you may need to take 75mg or 100mg.
Do not take sildenafil more than once per day.
Who Can Take Sildenafil?
Most men over the age of 18 can take sildenafil. However, it’s not suitable for everyone. You shouldn’t take sildenafil without consulting your doctor first if you:
- have a serious problem with your heart or liver
- have ever had an allergic reaction to sildenafil
- have ever had an allergic reaction to any other medication
- are taking nitrates for chest pain (angina)
- have recently had a stroke or heart attack
- have a stomach ulcer
- have low blood pressure
- have a condition that affects your blood cells, such as sickle cell anaemia, leukaemia or multiple myeloma
- have a problem with bleeding, such as haemophilia
- have a deformity of your penis, or a curved penis (Peyronie’s disease)
If you aren’t sure if it is safe for you to you take sildenafil, speak to a member of our discreet and knowledgeable team.
Alternatives to Sildenafil
In recent years, a number of medications have been developed to treat erectile dysfunction. You may need to try a few to find the treatment that works best for you.
The most popular alternatives to Sildenafil are:
- Cialis (sold generically as Tadalafil)
- Vardenafil (originally branded as Levitra)
- Spedra (also known as avanafil)
Sildenafil Vs Cialis
Cialis, or Tadalafil, is one of the best-known ED treatments on the market. The main benefit of Sildenafil over Cialis is that it works fast. When you take Sildenafil, you could achieve an erection in as little as 30 minutes, while Cialis takes up to two hours to become effective.
However, unlike Sildenafil, Cialis can be taken on an empty stomach and lasts up to 36 hours, compared to just four hours for Sildenafil.
Sildenafil Vs Vardenafil
Originally sold as Levitra, Vardenafil works in a similar way to Sildenafil. The main differences between these two medications are that Vardenafil lasts a little longer (up to five hours) and is less affected by food than Sildenafil. The main exception is grapefruit, which has been shown to significantly reduce the effects of both medications.
Sildenafil Vs Spedra
Spedra (known generically as avanafil and sold as Stendra in the US) can start to work faster than Sildenafil, in as little as 15 minutes. Unlike Sildenafil, Spedra is effective when taken with or without food and its effects last slightly longer, with most men benefitting from the medication for an average of six hours.
How to Take Sildenafil
Sildenafil is an oral medication that can be swallowed with or without water. While it usually takes between 30 and 60 minutes to start working, you can take it for up to four hours before you want to have sex, meaning that it doesn’t need to interrupt your activities before penetration takes place.
Top Tips for Taking Sildenafil
- Swallow tablets whole with water
It’s best to take sildenafil on an empty stomach
Taking sildenafil with food may mean that it takes longer to work
I’ve Taken Too Much Sildenafil, What Should I Do?
Taking more than the recommended dose of sildenafil could cause a range of unpleasant effects including:
- headaches
- dizziness
- indigestion
- blocked nose
- vision changes
Call Your Doctor Immediately if…
Serious side effects related to sildenafil are extremely rare. However, you could call 999 or speak to an emergency health professional immediately if you:
- suddenly experience vision loss or severe change to your vision
- have a seizure
- have a painful erection
- have an erection that lasts for longer than two hours
- you experience any chest pain
- you experience any symptoms of an allergic reaction, such as your lips, mouth or tongue becoming swollen, breathing difficulty or feeling very unwell
Sildenafil Ingredients
Each Sildenafil tablet contains sildenafil as the active ingredient at a strength of either 25mg, 50mg or 100mg.
Each tablet also contains: microcrystalline cellulose, calcium hydrogen phosphate anhydrous, croscarmellose sodium, magnesium stearate, poly(vinyl alcohol), titanium dioxide (E171), macrogol 3350 & talc.
Please note that different manufacturers may use different inactive ingredients. Please contact us for specific details or if you require a specific brand.
Sildenafil Warnings
Sildenafil tablets may not be suitable if any of the following apply:
- You suffer from heart disease or heart rhythm problems
- You have had a heart attack or stroke within the last six months
- You have high or low blood pressure
- You suffer from liver or kidney disease
- You are a haemophiliac
- You suffer from sickle cell anaemia or leukaemia
- There is a physical deformity of the penis
- You suffer from retinitis pigmentosa
- You have a stomach ulcer.
If any of the above apply, it is important to let your doctor know so they can judge whether Sildenafil tablets will be safe for you to use.
Sildenafil tablets can lower the blood pressure. For most men, this isn’t a concern. However, this effect on blood pressure can be exaggerated if Sildenafil is taken with a nitrate drug, such as Isosorbide or Glyceryl Trinitrate (GTN). If taking nitrate drugs, then Sildenafil tablets should not be used. Sildenafil tablets should be used with caution if combined with alpha-blockers due to the potential hypotensive effects.
Sildenafil: Side Effects and Risks
All medications can cause side effects, and sildenafil is no exception. However, this doesn’t mean you will definitely experience them. In fact, men who take sildenafil for erection problems are unlikely to experience any side effects at all since they only take this erectile dysfunction medication for a short time. Nevertheless, some of the most common sildenafil side effects to be aware of include:
- headaches
- nausea
- hot flushes
- indigestion
- dizziness
- stuffy nose
Important information: Grapefruit and grapefruit juice can interact with sildenafil by affecting the way that they are metabolised by your body. This can increase your risk of side effects and reduce the effectiveness of your erectile dysfunction medication.
Please see the Patient Information Leaflet for a full list of side effects and warnings.

Sildenafil Tablets (25mg, 50mg & 100mg) FAQs
Erectile dysfunction can be caused by many different things, including:
- stress
- tiredness
- drinking too much alcohol
- depression or anxiety
There are also a range of health problems that can make you more likely to have erection problems too, such as diabetes, high blood pressure and high cholesterol. In fact, studies have found that erectile dysfunction is often an early indicator of an increased risk of cardiovascular diseases.
For most men, Sildenafil will start to work around 30 minutes after it is taken, although it can produce an effect after anywhere from 20 – 60 minutes.
The time it takes to kick in can vary from person to person, and it can be influenced by other outside factors. If Sildenafil is taken with a heavy or high-fat meal or with high amounts of alcohol, it can take longer to have an effect and may even be less effective.
Unless you experience any adverse reactions, there’s normally no reason why you can’t continue to take sildenafil for erectile dysfunction as long as you need to. We offer comprehensive ongoing care and customer support, so if you have any concerns about your treatment, you can get in touch with our expert team.
Sildenafil is thought to be effective at producing an erection in around 75% of men suffering from erectile dysfunction. It is the most well-known and popular erectile dysfunction tablet that has rightly gained a reputation as an effective, trusted treatment.
Many men find that the starting dose of 50mg is a suitable dose. However, it can be increased to 100mg Sildenafil tablets if required.
It can take a number of attempts at using Sildenafil before it is effective. It is recommended to try taking Sildenafil on 8 separate occasions before increasing strength or trying a different ED tablet. Those who find Viagra/Sildenafil ineffective may wish to try an alternative ED treatment such as Cialis, Levitra or Spedra.
Although most tablets for erectile dysfunction have a similar mechanism of action, some men may respond differently to individual treatments. If one tablet is ineffective, you may find you are more sensitive to a different treatment.
Sildenafil should be taken on its own, as it may interact with other ED treatments. Speak to your doctor or pharmacist before seeking alternative ED treatments. Viagra is prescription-only for a reason — medical professionals need to know what other medication you are taking to ensure it’s safe.
Some herbal or Viagra ‘alternatives’ like Kamagra can be dangerous or harmful, and we do not recommend you use any unlicensed substances whilst taking Sildenafil.
There are no studies currently available showing a link between Sildenafil and any change in male fertility. Although there may be many individual stories available on the Internet claiming a decrease (or increase!) in male fertility after taking Sildenafil, these are not supported by any scientific evidence.
There are many supplements available online that claim to help to treat erectile dysfunction. They include L-Arginine, Yohimbe, Dihydroepiandosterone (DHEA), Panax Ginseng, Horny Goat Weed and many more.
The difference between Sildenafil and these other supplements is that Sildenafil is a licensed medicine that has been clinically proven in clinical trials to be both safe and effective. As a medicine, it also undergoes a strict manufacturing process to ensure that every pack meets the required standards for human use.
On the other hand, supplements like the ones named above do not require any clinical proof of effectiveness or safety. They do not have any manufacturing legislation to ensure they are properly produced.
In short, not only is there no definitive proof that any of the supplements available are effective, but more importantly, there is not always any evidence that they are safe for human consumption. This is especially true as most require high doses to be taken. Additionally, many supplements do not contain the advertised ingredients, as noted in many prominent news stories where people have harmed themselves by taking unproven supplements that have been bought online.
We strongly advise our customers to avoid using supplements for the treatment of erectile dysfunction and stick to proven licensed medicines.
Men with heart problems should use Sildenafil with caution. This is because Sildenafil can also widen the blood vessels that feed the heart, increasing the blood flow and putting the heart under increasing strain.
Any men suffering from heart issues should always see their healthcare provider to discuss taking Sildenafil or any other ED treatment. Suitability will depend on individual circumstances and the severity of symptoms; therefore, your own doctor should initiate any treatment. This ensures that a safe and appropriate solution is found.
You can buy up to 32 tablets of Viagra or Sildenafil citrate tablets online from The Independent Pharmacy. This ensures that men can buy sufficient quantities of Viagra or Sildenafil in one order whilst ensuring that we can maintain the safe and responsible operation of our pharmacy.
It is safe to buy Sildenafil online as long as you are buying from a reputable source like a registered online pharmacy. The fact that Sildenafil is cheaper than Viagra is not a reflection of the treatment’s quality or effectiveness. There are a number of things to look out for when buying Sildenafil online to ensure you are buying from a reputable source. You can read about them here.
There are a number of advantages to buying erectile dysfunction treatment online, such as:
- Discretion – Many men do not like to discuss their condition as they may find it difficult or embarrassing. Buying online from The Independent Pharmacy bypasses the need for a face-to-face consultation without sacrificing service or safety.
- Price – Buying Viagra or Sildenafil online may prove to be more cost-effective than paying for a private prescription from a clinic or GP and then paying on the high street.
- Quantity – Most GPs normally only prescribe around two boxes of Sildenafil at a time due to financial pressures on the NHS. The Independent Pharmacy allows men to buy up to eight boxes of Viagra or Sildenafil at a time to ensure an adequate supply.
- Convenience – It is becoming increasingly difficult to get an appointment with your GP and find time away from work or family pressures to get the treatment you require. Ordering online allows you to buy at a time that suits you without the need to leave your living room.
- Expert information – Often, in busy GP surgeries and pharmacies, you can end up not getting all the information you require with your treatment.

Plus, if you can’t find what you’re looking for, our healthcare experts are available free of charge by telephone and email.
Erectile dysfunction is a common condition that occurs if you are unable to get or keep an erection. It’s very common, but it can be frustrating and embarrassing. Some people have isolated experiences of erectile dysfunction, but for some men, it happens every time they try to have sex. However you are affected, you aren’t alone. More than half of men over the age of 40 report having had erectile dysfunction.
The most obvious symptom of erectile dysfunction is not being able to get an erection at all, or not being able to get or keep an erection that is firm enough for sexual intercourse. Some men with erectile dysfunction also require a lot of stimulation to be able to get or keep their erection.
Experts believe that making some positive changes towards a healthier lifestyle could reduce your risk of developing erectile dysfunction. This includes taking steps like:
- achieving and maintaining a healthy weight
- stopping smoking
- eating a healthy, balanced diet
- exercising every day
- reducing stress in your life
- not drinking more than 14 units of alcohol every week
We know that talking to a healthcare professional about erectile dysfunction may seem frightening or embarrassing, but our discreet, reassuring and knowledgeable team are here to help. If you are experiencing regular episodes of erectile dysfunction, and/or you feel that your impotence is affecting your quality of life, make an appointment to speak to us.
There’s no permanent cure for erectile dysfunction, but sildenafil is one of the most popular treatments for this common condition, and while it’s sold under many brand names, the generic version is identical and therefore just as effective.
If you are having issue with erectile dysfunction, speak to our team who will be happy to discuss your personal circumstances and see if sildenafil is right for you.
There are many different treatments for erectile dysfunction meaning that there are plenty of alternatives to sildenafil if it’s not suitable or effective for you. These include:
- other oral medications, like vardenafil and tadalafil
- vacuum pumps
- penile implants
If you aren’t sure which treatment is right for you, book a free, online consultation with a licensed pharmacist.
