What is Viagra?

• Sildenafil belongs to a group of medicines called phosphodiesterase type 5 inhibitors.
• It is only taken before sexual activity.
• It works by increasing blood flow to the penis, helping men achieve an erection.
• Sildenafil takes 30 to 60 minutes to take effect. Many men can still achieve an erection up to five hours after taking it.
• Always read the patient information leaflet before use.

What Causes Erectile Dysfunction?

Erectile dysfunction has several causes and is more common in men over 40. Occasional difficulties with erections are normal and may be due to stress, tiredness, anxiety, or excessive alcohol consumption.

Medical conditions can also contribute to erectile dysfunction, causing persistent issues. These may include blood vessel problems, high blood pressure, high cholesterol, diabetes, spinal injuries, or nerve damage. Treating the underlying condition is important; however, Sildenafil can help provide effective treatment for erectile dysfunction itself.

How does Sildenafil work?

For an erection to occur, sexual arousal is required. During stimulation, nerve signals cause the muscles in the penis to relax, allowing blood to flow in. This expands the penis and causes an erection.

When erectile dysfunction is caused by restricted blood flow, Sildenafil helps by widening the blood vessels. This allows more blood to reach the penis, making it easier to achieve and maintain an erection when aroused. Sildenafil will only work when you are sexually stimulated.

How is Sildenafil Taken?

Sildenafil is available as tablets and liquid. Tablets are to be swallowed whole with water. The standard dose is 50mg, taken about an hour before sex. For best results, take it on an empty stomach as food may delay its effects.

If 50mg is ineffective or does not last as long as expected, speak to a prescriber to see if a higher dose is suitable.

What is the recommended dosage?

Sildenafil comes in different strengths, from 25mg to 100mg. Many men find that 50mg is effective, but the dose can be increased to 100mg if needed.

Some men may experience side effects with 50mg and prefer to lower their dose to 25mg. A prescriber can help determine the right dose for you.

Only one dose of Sildenafil should be taken in a 24-hour period.

What side effects can it have?

Like all medicines, Sildenafil can cause side effects. These are usually mild, but speak to a healthcare professional if any of the following persist:

• Hot flushes or facial redness
• Headaches
• Dizziness
• Nausea or indigestion
• Blurry vision
• Blocked nose

These effects occur because Sildenafil widens blood vessels in other parts of the body.

Some side effects are more serious. Seek medical help immediately if you experience:

• Chest pain
• A painful or prolonged erection that lasts over four hours
• Sudden vision loss
• Serious skin reaction
• Seizures

What warnings does Viagra (Sildenafil) come with?

Sildenafil is not suitable for everyone. At PharmXtra, a prescriber will assess your consultation to determine if it is right for you. You may not be able to take Sildenafil if you:

• Use nitrates for chest pain
• Use recreational drugs known as poppers
• Have heart or blood vessel disease, including low blood pressure, angina, or a previous heart attack
• Have had a stroke
• Have liver or kidney disease
• Have a stomach ulcer or another condition that causes bleeding

• Have loss of vision
• Have any disease or deformity of the penis

• Have previously had a reaction to Sildenafil or another medication

Avoid grapefruit juice while taking Sildenafil as it can increase the amount of the medicine in your blood, raising the risk of side effects.

Drinking more than 14 units of alcohol per week can also make it harder to achieve an erection. To get the best results from Sildenafil, avoid alcohol before sexual activity.
