How do sildenafil tablets work?
Sildenafil tablets work by relaxing and widening blood vessels, allowing more blood to enter the penis, upon sexual stimulation. This enables men to achieve and maintain an erection.
Important note: Sildenafil will not increase your sex drive. If you are experiencing low libido, you should visit your doctor or pharmacist.
How long do sildenafil tablets take to work?
Sildenafil tablets take around 30-60 minutes to kick in.
The amount of sildenafil in your bloodstream peaks around 60 minutes after consumption, but it can take 30 minutes before it starts working.
Pharmacist’s tip: Sildenafil tablets are most effective when taken on an empty stomach, as it acts quicker this way. You can take a tablet after eating a meal, but this can affect the absorption and sildenafil may take longer to take effect. Fatty meals make it more difficult for sildenafil to enter the bloodstream and can reduce the absorption of the drug.
How long do sildenafil tablets last?
Sildenafil lasts for around 4 hours on average. This time frame may vary depending on certain factors. These include whether you take sildenafil on an empty stomach or after a meal, your metabolism, your weight, and the dose you take. Other factors such as your age, other medication you take, your general health and your state of mind can also affect how long the effects of sildenafil last.

Sildenafil interactions

- Nitrates – Used to treat angina. Examples include isosorbide mononitrate, isosorbide dinitrate, glyceryl trinitrate
- Guanylate cyclase stimulators – Used to treat conditions such as heart failure and high blood pressure in the lungs. Examples include riociguat

Sildenafil interacts with over 250 different drugs. You should always let your doctor or pharmacist know of any medication you are taking, or planning to take, including recreational drugs. This is to check for dangerous interactions. It may still be possible to take sildenafil, but adjustments to the dosage may be suggested.
Sildenafil dosage instructions
Take one sildenafil tablet around 1 hour before sexual activity. Food can affect the absorption of sildenafil, so for best results, you should take sildenafil tablets on an empty stomach or eat a light meal beforehand.
Sildenafil is available in three different dosages: 25mg, 50mg and 100mg. You should try taking the prescribed dose on a few different occasions, before deciding whether or not it is effective for you.
Sildenafil 25mg tablets
Sildenafil 25mg is the lowest dose available. Your doctor or pharmacist may recommend that you take sildenafil 25mg tablets if you are using medication that can cause an interaction, or if you have a certain medical condition.
Your doctor or pharmacist may also suggest that you try sildenafil 25mg tablets if you are experiencing side effects with the 50mg tablets.
Sildenafil 50mg tablets
Sildenafil 50mg is the standard dose and the recommended starting dose if you are taking sildenafil for the first time. Most men will find that sildenafil 50mg tablets are effective and work well without intolerable side effects.
If the 50mg tablets are not working well for you, your doctor or pharmacist may increase the dose to 100mg.
If you are experiencing side effects which are bothering you, you should reduce the dose to 25mg.
Sildenafil 100mg tablets
Sildenafil 100mg is the maximum dose that you can take.
Your doctor or pharmacist may suggest that you try sildenafil 100mg tablets if the 50mg dose is not working well for you and you are not experiencing any side effects. There is a higher chance of experiencing side effects as you increase the strength.
Important note: The maximum dose of sildenafil is 100mg daily. You should never take more than 100mg of sildenafil within 24 hours. Taking too much sildenafil can cause dangerous side effects such as low blood pressure and priapism. You should seek medical attention if this happens. Always consult your doctor or pharmacist to discuss the most appropriate sildenafil dosage.

Sildenafil is safe to take for a lengthy period of time. There do not appear to be any long-term side effects from taking it. However, if you have certain medical conditions, you should consult with your doctor to check that it is safe for you to take.
Please see NHS: Sildenafil (Viagra) online resource.
Important note: You should not take sildenafil if you do not have ED. It will not make you last longer or give you a bigger erection. Taking sildenafil without ED can reduce your erectile confidence.
Sildenafil may make you feel dizzy or lightheaded. You should assess your response to sildenafil before proceeding to drive or operate machinery.
All drug manufacturers are free to produce sildenafil and many of them do. They are known as generic (non-branded) medicines. There is no difference in how effective each brand is. Chemist Click obtains stock from reputable UK wholesalers, and they all contain the same active ingredient, sildenafil citrate. There may be slight differences in the other ingredients, such as the binding agents (what holds the drug into place) and the colouring. Common generic brands we stock include Teva and Accord. However, we can also obtain Pfizer, Mylan, Bristol, Dr Reddy, Sandoz, Actavis and Torrent brands. If you wish to obtain a certain generic brand, please make a note of this on your consultation form.
Our consultation process has been designed to assess the individual seeking treatment. It should be treated similarly to a doctor's consultation and cannot be completed on behalf of someone else. This is for safety reasons and in the best interests of our patients.
You should not take more than one sildenafil tablet within a 24-hour period. If you feel that sildenafil is not effective, you should discuss increasing the dose or trying a new treatment with your doctor or pharmacist.
Tip: Exceeding the prescribed dose can cause unwanted side effects.
It is possible to split sildenafil tablets in half. Some tablets are scored with a line down the middle, making it easier to break in half. For those that aren't you should use a tablet cutter. This helps to ensure tablets are split evenly and minimises wastage by reducing any residue that can fall off a tablet when split incorrectly.
Sildenafil should not be used together with other treatments for ED. This can result in an overdose which can be harmful to your health. You should leave a 24-hour gap between taking sildenafil and trying another ED treatment.
Drinking alcohol whilst taking sildenafil can be safe, but only if you are drinking in moderation. Excess alcohol consumption can intensify side effects, and even contribute to erectile dysfunction. Alcohol slows down certain functions of the body, and constricts blood vessels, limiting blood flow to the penis. Sildenafil works to increase blood flow to the penis, and as a result, can counteract the effects of the drug.
There are also long-term effects of drinking and using sildenafil. It can cause inflammation of the prostate gland, which is linked to erectile dysfunction. Excess alcohol consumption can also reduce testosterone levels, which contributes to ED.
Sildenafil and Viagra both contain the same active ingredient, sildenafil citrate. They are medically equivalent and work in the same way. In essence, sildenafil is as good as Viagra. They also are identical in their efficacy, safety and side effects. Both are available in the same dosages (25mg, 50mg, 100mg).
The reason why Viagra is more expensive is because Pfizer developed Viagra in 1996, investing heavily in product development and marketing. Once their exclusive license to be the sole manufacturer expired, it gave an opportunity for other pharmaceutical companies to start manufacturing Sildenafil as a non-branded medication.
Competition in the market is what keeps the price cheap. Most people who have taken Viagra will eventually turn to sildenafil, as it is a cheaper option that provides the same results.
Tip: Generic sildenafil contains the same active ingredient, but is available at a much lower price.
Cialis is another form of medication used to treat ED. It has an advantage over sildenafil as it works in as little as 30 minutes, and has a longer duration of up to 36 hours. However, this can be a disadvantage if you experience side effects, as they are also likely to last longer.
Whilst sildenafil has been around for longer than Cialis, both drugs have been around for over 18 years, and have proven to be safe and effective treatments for ED. Despite the differences between sildenafil and Cialis, both remain to be effective treatments for ED.
You can buy sildenafil over the counter in the form of Viagra Connect or Eropid, but they are only available in a 50mg strength. You will need to have a consultation with a pharmacist to ensure that treatment is safe for you.
You can get sildenafil on the NHS if you have certain medical conditions, such as diabetes. The limit is usually 4 tablets per month. If you require more than this, you are required to obtain treatment privately.
If sildenafil 50mg has worked, but you have experienced side effects, sildenafil 25mg can provide the same effect, with a lower chance of side effects.
If sildenafil 25mg does not work and you are taking sildenafil for the first time, try taking it again. Current guidelines state that you should take the tablets on 8 separate occasions, before thinking about increasing the dose. You should discuss this with your pharmacist or doctor beforehand. If you are taking sildenafil 25mg to reduce side effects after having taken the 50mg tablets, follow the same advice. If you are still not experiencing the desired effect with the 25mg tablets, you may wish to speak to your doctor or pharmacist about an alternative treatment.
If your doctor or pharmacist has instructed you to take 50mg, you can take two 25mg tablets to make up 50mg. You should not take two 25mg tablets at different times on the same day.
Sildenafil 100mg is the maximum dose that can be used safely. It is usually used where there is limited response to the 50mg strength. This should only be done on advice of a doctor or pharmacist.
You should not take two sildenafil 100mg tablets together, or on the same day. This can cause unpleasant side effects, including dizziness, headache and feeling sick. If you have taken more than 100mg of sildenafil in one day, seek medical attention. It is important to note that higher strength tablets will not work any quicker than the lower strengths, nor will it last for longer. Higher strength tablets are more likely to produce a response where there has been no response to the lower strengths.
You are able to split sildenafil 100mg tablets in half to give you sildenafil 50mg. However, you run the risk of wastage if the tablet is not split accurately. If you wish to do this, you should use a pill cutter.
Sildenafil does not affect sperm function or sperm quality. It does not interfere with your chances of getting pregnant.
The most common side effect of sildenafil is headache and light headedness. These side effects pass after a few hours.
For best results, sildenafil tablets should be taken 1 hour before food, preferably on an empty stomach. You should try to avoid alcohol in order to get the best results.
Sildenafil is not available as a jelly or chewable tablet in the UK. It is available as a liquid; however, this is a special preparation that is made in a laboratory, and very costly.
The best time to take sildenafil is 1 hour before sexual activity.
If you order before our daily cut off time, you can receive your order the next day.
If sildenafil tablets are not working, you should continue to take the tablets and use them on 8 separate occasions. There may be several reasons why sildenafil is not working. You should try taking a tablet on an empty stomach, avoiding alcohol, and leaving enough time to allow the tablet to work. You may also want to try using sildenafil in different scenarios.
If after 8 separate attempts you find that sildenafil is not providing the desired effect, you should speak to your doctor or pharmacist. There are alternative treatments such as:
- Cialis Tablets
- Eropid Tablets
- Levitra Tablets
- Spedra Tablets
- Tadalafil Tablets (Take a look at our article on Sildenafil vs Tadalafil for more information)
- Vardenafil Tablets
