Viagra helps to maintain the erection after ejaculation and reduces the refractory time before a second erection can be obtained. These medications may be combined with various creams aimed at reducing sensitivity.
Drinking large amounts of alcohol can make it hard to get or keep an erection. This is called erectile dysfunction (ED). Alcohol interferes with the messengers in the brain that tell the penis to fill with blood. It can also happen because alcohol can reduce the production of testosterone.
Sildenafil (brand name Viagra) is a medication for erectile dysfunction (ED). It works by enabling blood flow to the penis by inhibiting an enzyme that causes an erection to deflate. Viagra can make your erection seem firmer and therefore bigger. But it won't increase the size of your penis permanently.
Most commonly you might experience some flushing, stomach ache or indigestion, or a headache. If you do have any mild side-effect reaction to Viagra, you can also consult your prescriber to see if a lower dose might work better for you.
For erectile dysfunction, some basic questions to ask your doctor include:
- What's the most likely cause of my erection problems?
- What are other possible causes?
- What kinds of tests do I need?
- Is my erectile dysfunction most likely temporary or chronic?
- What's the best treatment?
Taking Viagra without an ED diagnosis can mask the fact that you're actually really suffering and can jeopardise your long-term sexual performance. If you do have ED, fake pills can worsen the psychological effects, making you think you're in worse shape than you really are.
This study demonstrates that administration of sildenafil at doses of 150–200 mg results in sufficient rigidity to achieve vaginal intromission and complete satisfactory sexual intercourse in 24.1% of ED sufferers who had previously failed a trial of sildenafil 100 mg.
The usual recommended dosage is 50mg (range 25mg to 100mg), taken when needed, an hour before sexual activity. However, it may be taken anywhere from 30 minutes to four hours before sexual activity. Do not exceed the maximum recommended dose.
Before taking sildenafil,do not take sildenafil if you are taking or have recently taken riociguat (Adempas) or nitrates (medications for chest pain) such as isosorbide dinitrate (Isordil), isosorbide mononitrate (Monoket), and nitroglycerin (Minitran, Nitro-Dur, Nitromist, Nitrostat, others).
Sildenafil and Viagra work the same; they're equally effective, require the same amount of time to take effect, and they work for the same duration. The main difference between Sildenafil and Viagra is the branding and the price. Viagra tablets inevitably cost more than the generic Sildenafil medication.
Viagra normally starts working 30 to 60 minutes after you take it in oral tablet form. It may take up to 2 hours to work. Viagra doesn't work on its own.
In the United States, you'll need a prescription for both name-brand Viagra and generic sildenafil. Costs for both vary. Viagra costs an average of about $70 per pill, while sildenafil can cost about $40 per pill, depending on dosage.
50 mg is the most commonly prescribed dose (but that doesn't necessarily mean it's right for you). Sildenafil can also be prescribed off-label (as the generic form of a drug called Revatio) in 20 mg, 40 mg, 60 mg, 80 mg, and 100 mg doses.
Can you take Viagra every day? The short answer is yes; you can take Viagra or its generic form, sildenafil, every day.
