Sildenafil is a proven, effective medication to treat erectile dysfunction (ED) that you can buy at OnlineClinic. It is also the active ingredient in the tablets, as well as in the branded version of the ED medication Viagra. It has been proven to work within half an hour of taking the pill, and can last up to five hours.

To make the most out of your ED medication, you can adopt a number of tactics, such as low-fat meals and cutting back on alcohol. We will explain how to take Sildenafil, and how to get the most out of it below.

Sildenafil is medically known as a phosphodiesterase type 5 (PDE-5) inhibitor and is the generic unbranded medication for ED. Using the active ingredient of the same name, Sildenafil prevents the chemical 'phosphodiesterase type 5' from functioning to allow more blood to enter the penis through relaxing the blood vessels in the area.

As Sildenafil interacts with chemical messengers, known as cyclic GMP, this means you will need to be aroused within the first five hours of taking the tablet to experience an erection. Taking ED medication like Sildenafil doesn't mean you will be erect for five hours continually.

As Sildenafil is taken on a needs-be basis, you don't need to remember a certain time of the day or week. Instructions are easy to remember and are as follows:

• Take one tablet, swallowed whole with a sip of water
• Do not take more than one tablet within 24 hours
• Effectiveness can start in as early as half an hour
• On average, Sildenafil will work between 30-60 minutes
• Sildenafil will remain effective for up to five hours

ED medication is simple to take, with quick reactions, however, there are some scenarios that slow down effectiveness:

• Taken on an empty stomach, or keeping meals small and light in fat means the pill is absorbed into the system quicker
• Alcohol can reduce effectiveness
• Grapefruit can interact with ED medication, provoking side effects

There are three dosages of Sildenafil available (25mg, 50mg and 100mg) and you can buy all three here at OnlineClinic. 50mg is the middle ground and recommended dosage, proving to supply maximum success with minimal side effects. If you find the 50mg is ineffective, you can buy the higher dosage of 100mg. On the other end of the spectrum, if you have experienced side effects with the 50mg dose, you may be prescribed 25mg.

As Sildenafil is only taken when needed, there is a very small chance that you will experience side effects, however if you do, these are often temporary and highly manageable; aches and muscle pain, diarrhoea, flushing, headaches, stomach ache (indigestion), cold symptoms or trouble sleeping. The full list of possible side effects can be found in the medication patient leaflet at the right of this page. If you are experiencing particularly severe side effects, it is advised to stop taking the medication and contact your doctor.

There are also some precautions to take when using Sildenafil for a minority of users. It goes without saying that women should not use any erectile dysfunction medication. Some other precautions include the following:

• Decreased kidney function
• Decreased liver function
• In elderly people
• Cardiovascular disease

If you have experienced any of the following, you may not be prescribed Sildenafil, or you need to use in caution:

• Heart failure
• Stroke
• Low blood pressure

There are other precautions that should be considered when taking ED medication. When completing a consultation, any medical history with you or direct family should be disclosed so our doctors can recommend alternative treatment, or the correct dosage.
