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 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.
