Viagara - information and a buyer's guide
There are millions of men in the UK, Europe and the US who suffer from the symptoms of erectile dysfunction (abbreviated to ED and also known as impotence). Until the past few years, treatments for ED included injections, vacuum pumps or even surgery. These procedures were embarassing, possibly painful and not always that effective.
Since the introduction of Viagara® by Pfizer, Inc., men's lives have been completely transformed. It even works for many men with physical reasons for ED such as after surgical removal of the prostate gland.
What does viagara do?
Viagara (generic name Sildenafil) is a treatment for erectile dysfuntion in men. It is used to help men to achieve and maintain an erection when they are sexually aroused.
Note that is does not offer protection against STD's including HIV, and you are still advised to wear a condom if you are unsure of your partner's sexual history.
What are the side effects?
Side effects of this medication can include: headaches, hot flushes, indigestion, blocked nose, urinary tract infection, abnormal vision (a slight or transient colour tinge, sensitivity to light or blurred vision), diarrhoea, dizziness and a rash.
Who should not take this drug?
You should not take this drug if you have any heart problems. It is a good idea to discuss whether or not viagara is right for you with your doctor before making a purchase online. In particular, you should not take viagara if you are on any drugs containing nitrate. This is because taking drugs that contain nitrate in combination with viagara can make your blood pressure drop to unsafe levels, leading to dizziness, light headedness, or in the worst case scenario, a heart attack.
What is the recommended dose?
It can be taken in one of three doses - 25mg, 50mg and 100mg. You should start at the lowest dose to see if it has the desired effects. Indeed, a dosage of 50mg is sufficient in most men, and if 100mg tablets are bought, these can be split in two to provide two doses. You should not take the highest dose of 100mg unless advised to do so by your doctor, and men over 65 should not take a dose higher than 25 mg as they can be more sensitive to its effects and side effects.
It should be taken about an hour before intercourse is to take place, and the effects last for about four hours. It should not be taken more than once per day.
If you have an erection that lasts for more than four hours you should seek medical help immediately.
