Viagra vs cialis
Weighing the benefits and risks. Cialis versus, viagra requires some basic knowledge of each. A brief comparison of Viagra (Sildenafil) versus Cialis (Tadalafil) can be viagra vs cialis made by examining how they can be used (as needed for either or daily for Cialis the time it takes for them to work, the length of time they continue to work, the restrictions. Yet, one issue is rarely the sole factor men consider when taking a medication for erectile dysfunction. It is the interplay between a mans social circumstances (and that of their partner his need for a rapid onset of medication activity versus a prolonged duration of action, the individual reaction to the drug in terms of side viagra vs cialis effects, a persons prior medical history. Sildenafil (Viagra) can be effective in as little as 1 hour, while Cialis might not take effect for 2 hours, though for some patients these medicines can work more rapidly. In fact, Cialis (tadalafil) might work in as few as 30 minutes and some patients find that Viagra (sildenafil) can start to have an effect in 15 minutes. Nevertheless, each should be approached as reliably taking effect in 1 hour for Viagra and in 2 hours for Cialis. Cialis which DO MEN prefer? Cialis which DO women prefer? Viagra leaves the body in about 6 to 8 hours, while Cialis can work for 24 to 36 hours. That means that while they are both very effectiveapproximately 75 of patients will achieve a satisfactory erection with eitherViagra (sildenafil) will work reliably for 6-8 hours but Cialis (tadalafil) will work for up to 36 hours. Nevertheless, the effect of a medication may not be needed beyond 6 or 8 hours, and any side effects (in addition to any positive effect) they cause will fade rapidly as the medication leaves the bloodstream. That means that someone who experiences nasal congestion or flushing when they use either Cialis (tadalafil) or Viagra (sildenafil) may find it useful to take the shorter acting medication, Viagra (sildenafil). It might be worth a bit of nasal congestion during the time when sex will occur but there would be no reason to endure a stuffy nose once sexual intimacy had concluded. Sometimes, a peculiar side effect might prevent a person from taking Sildenafil but not Tadalafil. Cialis (Tadalafil) is more likely to cause back pain than Sildenafil (Viagra) but seems to cause less nasal congestion. A man with a slipped disc may not like the idea of getting back pain even if it is just a side effect of medicine (and eliminate Cialis as a choice) while another patient with allergies may want to avoid taking something that will cause. The length of time a medicine works is important to some. Lets consider two men. One might be able to predict when sexual activity will occur. A drug that works rapidly and leaves his system quickly thereafter would be perfect, as with Sildenafil (Viagra). Another man might know sex will occur during the course of a weekend but cannot know exactly when that will occur. For him, a drug with a prolonged period of activity is far more important than how long it takes for a medicine to start working. He would prefer tadalafil (Cialis). Also, Cialis can be taken in a low daily dose and for a solid subset of patients, this is preferred. The key is to get educated and share all your information with each of your healthcare providers. Only by doing so can a safe, effective, and personalized treatment plan be crafted with your goals and your safety preserved. More Roman ED Drug Comparisons, viagra Alternatives.

How to enhance viagra effects
For other uses, see. Sildenafil, sold as the brand name. Viagra among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. 3, its effectiveness for treating sexual how to enhance viagra effects dysfunction in women has not been demonstrated. 3, common side effects include headaches and heartburn, as well as flushed skin. Caution is advised in those who have cardiovascular disease. Rare but serious side effects include prolonged erections, which can how to enhance viagra effects lead to damage to the penis, and sudden-onset hearing loss. Sildenafil should not be taken by people who take nitrates such as nitroglycerin (glycerin trinitrate as this may how to enhance viagra effects result in a severe and potentially fatal drop in blood pressure. 3, sildenafil acts by inhibiting cGMP-specific phosphodiesterase type 5 (phosphodiesterase 5, PDE5 an enzyme that promotes degradation of cGMP, which regulates blood flow in the penis. Pfizer scientists, andrew Bell, David Brown, and Nicholas Terrett originally discovered sildenafil as a treatment for various cardiovascular disorders. 4 5, since becoming available in 1998, sildenafil has been a common treatment for erectile dysfunction; its primary competitors are tadalafil (trade name Cialis) and vardenafil (Levitra). Contents Medical uses 50mg tablets of sildenafil Sexual dysfunction The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now one of the standard treatments for erectile dysfunction, including for men with diabetes mellitus. 6 Antidepressant-associated sexual dysfunction Tentative evidence suggests that sildenafil may help men who experience antidepressant -induced erectile dysfunction. 7 Pulmonary hypertension While sildenafil improves some markers of disease in people with pulmonary arterial hypertension, it does not appear to affect the risk of death or serious side effects as of 2014. 8 Raynaud's phenomenon Sildenafil and other PDE5 inhibitors are used off-label to alleviate how to enhance viagra effects vasospasm and treat severe ischemia and ulcers in fingers and toes for people with secondary Raynaud's phenomenon ; 9 10 these drugs have moderate efficacy for reducing the frequency and duration. 9 As of 2016, their role more generally in Raynaud's was not clear. 10 Adverse effects In clinical trials, the most common adverse effects of sildenafil use included headache, flushing, indigestion, nasal congestion, and impaired vision, including photophobia and blurred vision. 2 Some sildenafil users have complained of seeing everything tinted blue ( cyanopsia ). 11 Some complained of blurriness and loss of peripheral vision. In July 2005, the FDA found that sildenafil could lead to vision impairment in rare cases 12 and a number of studies have linked sildenafil use with non-arteritic anterior ischemic optic neuropathy. 13 Rare but serious adverse effects found through postmarketing surveillance include prolonged erections, severe low blood pressure, myocardial infarction (heart attack ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss. 2 In October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including sildenafil, required a more prominent warning of the potential risk of sudden hearing loss. 14 Interactions Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection. Protease inhibitors inhibit the metabolism of sildenafil, effectively multiplying the plasma levels of sildenafil, increasing the incidence and severity of side effects. Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours. 2 Other drugs that interfere with the metabolism of sildenafil include erythromycin and cimetidine, both of which can also lead to prolonged plasma half-life levels. The use of sildenafil and an 1 blocker (typically prescribed for hypertension or for urologic conditions, such as benign prostatic hypertrophy ) at the same time may lead to low blood pressure, but this effect does not occur if they are taken at least. 15 Contraindications Contraindications include: 2 :11 Concomitant use of nitric oxide donors, organic nitrites and nitrates, 16 such as: Concomitant use of soluble guanylyl cyclase stimulators, such as riociguat Known hypersensitivity to sildenafil Sildenafil should not be used if sexual activity is inadvisable due. Citation needed Nonmedical use Recreational use Sildenafil's popularity with young adults has increased over the years. 17 Sildenafil's trade name, Viagra, is widely recognized in popular culture, and the drug's association with treating erectile dysfunction has led to its recreational use. 18 The reasons behind such use include the belief that the drug increases libido, improves sexual performance, 18 or permanently increases penis size. 19 Studies on the effects of viagra when used recreationally are limited, but suggest it has little effect when used by those not suffering from erectile dysfunction. In one study, a 25-mg dose was shown to cause no significant change in erectile quality, but did reduce the postejaculatory refractory time. 20 This study also noted a significant placebo effect in the control group. 20 Unprescribed recreational use of sildenafil and other PDE5 inhibitors is noted as particularly high among users of illegal drugs.
