Levitra

Levitra - what is Levitra?
Levitra is the trade name for a drug called Vardenafil. Levitra is one of a class of drugs known as PDE-5 (Phosphodiesterase type 5) inhibitors. Levitra and the other PDE-5 inhibitors can help men with male impotence (erectile dysfunction) by enhancing the erectile response when a man is sexually stimulated. Aside from Levitra, the other drugs in this class are Cialis (Tadalafil) and Viagra (Sildenafil)
Levitra – is Levitra an aphrodisiac?
Levitra is not an aphrodisiac as it does not cause a man to be mentally sexually aroused. Levitra will only be effective if a man is mentally sexually aroused.
Levitra – how does Levitra work?
To understand how Levitra works you need to understand the mechanics of how a man gets an erection. When a man is sexually stimulated, the nervous system in the erectile tissue of your penis releases nitric oxide (NO). The nitric oxide stimulates an enzyme that produces a 'messenger' called cyclic guanosine monophosphate (cGMP). The cGMP causes the smooth muscle cells to relax. One result of this is that the arteries in the penis dilate and the blood can flow into the penis more easily. Another result is that the erectile tissue itself fills with blood. Both of these processes result in an erection. Levitra works by maintaining the level of cGMP in the smooth muscle cells. If you are not mentally sexually aroused, your brain will not stimulate the release of any nitric oxide and you will not produce increased levels of cGMP.
Levitra - is Levitra effective?
Clinical studies have shown that when compared to placebo, Levitra and the other drugs in the same class, result in significant improvement in erectile function. Although established to be a safe and effective drug, Levitra is not appropriate for everyone and may not work in all cases.
Levitra – how does it affect blood pressure?
Levitra can slightly lower blood pressure. This is not a problem for most men, but Levitra's effect on blood pressure is exaggerated if the Levitra is taken with a nitrate drug. Nitrates are one of the treatments doctors prescribe for angina. If you take Levitra when you are also taking nitrates, the combined effect of the Levitra and the nitrates can lower your blood pressure to such an extent that it could prove fatal. Never take Levitra when taking nitrates. Levitra – if I have a heart condition can I take it? If you have a heart condition it is important that you discuss this with the doctor before taking Levitra. Your doctor may actually recommend abstaining from sexual activity for a while. If your doctor has prescribed nitrates, then for the reasons described above you must not take Levitra.
Levitra – can women take it?
Levitra is not licensed for use by women.
Levitra – how quickly does it work?
Take a Levitra tablet about 25 to 60 minutes before sexual activity. With sexual stimulation you may achieve an erection anywhere from 25 minutes up to four to five hours after taking Levitra. This does not mean that your erection will last that long - simply that you will have the ability to attain an improved erection for that period of time. Eating a meal before taking Levitra should not delay Levitra from working.
Levitra – why are there different doses?
Levitra is available in three dosages: 5mg, 10mg and 20mg. Some men may respond to a lower dose of Levitra. Some men may already be taking medicines, other than nitrates, that interact with Levitra and in these cases need to adjust the Levitra dosage.
Levitra – what dose is right for me?
The doctor needs to decide which dosage of Levitra is most appropriate. The doctor will take into account potential drug interactions, your age, the severity of your impotence and any previous experience you have had with Levitra.
Levitra - what if it does not work the first time I use it?
Levitra might not work the first time you take it for various reasons. Most doctors advise taking Levitra at least eight times before trying a different medicine.
Levitra - what are the side-effects?
Levitra's side-effects are generally mild and brief. Levitra's most common side-effects are headache, facial flushing and nasal congestion.
Levitra - does it interact with other medicines?
Levitra interacts with many drugs. The following list is not complete but it is important to inform the doctor of all prescription and non-prescription medication taken, especially nitrate medications (e.g. glyceryl trinitrate (GTN), nitroglycerin, isosorbide mononitrate or dinitrate), nitroprusside, cimetidine, erythromycin, azole antifungals (e.g., itraconazole, ketoconazole), mibefradil, rifamycins (e.g., rifampicin), Alpha blockers (prescribed for prostate disease or high blood pressure), Ritonavir, and Amyl, Butyl or Isopropyl nitrates (“poppers”).
Levitra - who shouldn't use it?
Men who have any of the following conditions should also avoid taking it: severe heart or liver problems, recent stroke or heart attack, low blood pressure, certain rare inherited eye diseases.
Levitra - does it treat the underlying causes of impotence?
No. Levitra will not resolve the underlying cause of male impotence although if the cause is primarily psychological, it may help to break the cycle of anxiety and failure associated with being unable to achieve a satisfactory erection. Hence, any man complaining of impotence must be investigated for possible underlying causes of the condition.
What kind of tests might highlight the underlying causes of male impotence?
Any man experiencing impotence should have his blood pressure measured to check for undiagnosed cardiovascular disease. Additionally, a blood test for diabetes should be performed along with cholesterol and triglyceride blood tests. It is becoming increasingly accepted and practised among doctors that sex hormone levels (testosterone) should also be checked by way of a blood test, particularly in older men and men with any chronic diseases.
What other oral impotence treatments are available?
The other medicines, Viagra and Cialis work in similar ways. Cialis has a much longer half-life than Levitra and Viagra and therefore its effect lasts much longer. This does not mean one has prolonged erections but the length of time available for further erections is increased without the need to take further doses. It also means however that the side effects if present will last longer. Levitra, like Cialis, can be taken with food whereas Viagra should be taken on an empty stomach. Some studies have shown Levitra to be more suitable for men suffering from diabetes.
Are there alternatives to oral medicines?
Alternative treatments include Caverject (“Alprostadil”) which is a medicine injected directly into the penis and MUSE (another form of “Alprostadil”) which is a pellet inserted into the urethra. These may be of use for men who have to take nitrates and are therefore unable to take the PDE5 inhibitors. The use of vacuum pumps and other mechanical devices for producing and maintaining erections are alternatives to taking prescribed medicines. These alternative treatments are not available online
