Service only available to UK residents with repeats available no more frequently than 1 or 2 weeks at DIMEC Prescriber’s discretion. Levitra is the brand name of the drug vardenafil, a PDE5 (phosphodiesterase-5) inhibitor that is only available on prescription. Levitra can be dangerous if you take it at the same time as certain other medicines including some that are used to treat chest pain, high blood pressure or recreational drugs including alkyl nitrites (poppers). The usual starting dose for Levitra is one 10mg tablet taken at least 60 minutes prior to sex. You should NOT take more than 20mg of Levitra a day as this will not give a greater effect but does increase the risk of side effects.
If things didn’t as well as you’d hoped, but you did not experience any side effects, ask us if it is safe for you to try increasing your dose, say from 10mg to 20mg.
Getting used to having erections again and finding the right dose that works for you means that you should give yourself eight attempts before deciding that Levitra are not working for you.
The side effects of Levitra are usually mild to moderate and self-limiting but it is important to take the recommended dose.
This is why we insist that you read the patient information leaflet for any medicine prescribed to you.

We used data up to April 2001 from 272 practices contributing to the UK general practice research database. We identified 10 371 first time recorded cases of erectile dysfunction for an estimated 2.3 million man years of observation. Recorded diagnoses of erectile dysfunction more than doubled after sildenafil was introduced in the United Kingdom.
Studies into the causes of erectile dysfuntion should consider the period in which the study population was identified. We thank Susan Jick and Brian Bradbury for their helpful comments on an earlier version of the manuscript and the general practitioners who contribute information to the general practice research database.
Contributors: JAK conceived and designed the study, gathered the data for analysis, analysed the data, and drafted the manuscript.

Do not ever laugh or shrug off what medical bottles or boxes give you as side effects or warnings. Condition called priapismThe etymology of the word comes from Priapus, the Greek male fertility god.
Most Common Causes of PriapismThe most common causes of priapism are drugs that are used to treat impotence. Treatment of PriapismWhen erections last over 4 hours it is a very serious condition and medical care is required immediately.
Complications of PriapismBlood clotting is one of the most common complications of priapism. The medicine is available in three strengths - 5mg, 10mg and 20mg and in packs of 4 or 8 tablets. In addition, men with severe heart or liver problems or those that have had a recent stroke, heart attack (MI), or who have low blood pressure should not take it. If the desired effect is experienced but side effects are a problem then a 5mg tablet will be recommended. It may take a few tries before things start to work again, but many patients are not told this and expect the medicines to work like magic.
Sildenafil is contraindicated in men being treated with organic nitrates and should be used with caution in men with cardiovascular disease.2 Because sildenafil has been promoted extensively, and because no large, population based studies on the incidence of erectile dysfunction had been reported from the United Kingdom, we were interested in the incidence of the disorder and the characteristics of men with a diagnosis and whether these changed after the introduction of sildenafil. 3 4 Cases were men aged 40–79 years with at least two years of recorded medical history who had a first time diagnosis of erectile dysfunction that was recorded between January 1990 and December 2000. The annual incidence of erectile dysfunction increased gradually during the mid-1990s then rose twofold to threefold during the years 1998 to 2000 (figure). Levitra works by relaxing the blood vessels to the penis allowing better circulation, taking only 50 to 80 minutes to get to work. If 10mg is not effective and side effects are not problematic then a 20mg dose should be tried after further consultation. There are also other forms of treatment other than a tablet available such as creams or urethral suppositories.

We compared cases before (January 1990 to August 1998) and after (September 1998 to December 2000) the introduction of sildenafil. The prevalence of ischaemic heart disease among men with erectile dysfunction decreased after the introduction of sildenafil. This is better than promising your partner the earth and finding the extra pressure causes your erection to fail. We matched cases with comparison patients who had no recorded diagnosis of erectile dysfunction.
The prevalence ratios for diabetes, hypertension, hyperlipidaemia, and smoking changed less or did not change significantly.
However, doctors should not be any less concerned about the possibility of undiagnosed ischaemic heart disease in men presenting with erectile dysfunction.
Comparison patients were matched to the cases in a ratio of 5:1 by sex, year of birth, general practice, and date of diagnosis. The clinical characteristics of men with a diagnosis of erectile dysfunction evidently changed at least in part because of a contraindication or precaution in the use of the new drug. We calculated a prevalence ratio for various conditions by dividing the prevalence of the condition at the time of first diagnosis of erectile dysfunction by the prevalence among the comparison patients.
