How does Viagra work?

Viagra uses an active ingredient called sildenafil to widen and relax the arteries in your penis, allowing more blood to flow through. As more blood flows in and less flows out, the penis grows to an erect state.

Although Viagra can last for up to 4-5 hours your erection will remain for only a fraction of that time; after climax your penis will return to a flaccid state until the next time you become erect within the 4-5 hour timeframe.

Dosage information

The lowest Viagra dosage (25mg) is recommended for men aged 65 and above and those with serious liver or kidney problems. If you have never used Viagra before your doctor may also start you off with the lowest dosage.

You can choose to order a 50mg or 100mg Viagra tablet if you are aged below 65, or if your body tolerates the lowest dosage and you want to improve results next time around. A 121doctor may only prescribe the 100mg Viagra tablet to patients who they feel can benefit from treatment without endangering their health.

How to take Viagra

Swallow a Viagra tablet at least 30 minutes before to intend to have sex. You should not take more than one tablet every 24 hours and always stick to the Viagra dosage prescribed to you by the doctor.

Please note that meals high in fat can block the Viagra compound from functioning properly; to achieve the best possible results you should always avoid eating large fatty meals before using treatment.

If you have recently recovered from a heart attack or stroke please do not use Viagra. The following conditions may also prevent you from obtaining treatment:

• Severe heart disorder
• Low blood pressure
• Decreased liver function
• Galactose intolerance
• Lapp lactase deficiency
• Glucose-galactose alabsorption

Are there side effects?

Like all prescription medications, Viagra affects people in different ways. The most widely reported problem when using this medication is headache, which can occur for every 1 in 10 users. The following Viagra side effects are known to affect between 1-10% of users:

• Dizziness
• Indigestion
• Facial flushing
• Nasal congestion
• Visual disturbances, such as blurred vision, blue tinge to vision
• Uncommon Viagra side effects

A Viagra tablet should not be taken with any form of nitrate medication, as this can cause blood pressure to drop below normal. Viagra side effects are also caused if nitrate medication is used during treatment. A hazardous drop in blood pressure leading to dizziness or fainting can also occur in users who are taking alpha-blocker medicines.
