Two years and many clinical trials later, in March of 1998, the new medication — now called Viagra — received approval from the Food and Drug Administration and hit the market as a prescription medication for the treatment of erectile dysfunction.

Adverse effects

Also, patients must understand that it is normal to have to increase one’s dose as the problem of ED progresses and that nearly all patients who had initial success with ED pills will eventually lose that degree of success and may need other help. Both drugs take approximately 30 to 60 minutes to begin working and allow patients to achieve the erection they expect. Peak concentration in the blood is reached after two hours for tadalafil and about one hour for sildenafil. As such, we always suggest taking medication about an hour or two before sexual activity. The time it takes for the drug to function will vary between patients, so use prior experience as a guide.

How much Teva sildenafil is too much?

Of note, sildenafil, a generic Viagra, can be somewhat inhibited after eating a large meal containing fatty foods, and this is not a concern with tadalafil (generic Cialis). We often suggest sildenafil for married couples or long-term partners with a more predictable sex life. Cialis may be more appropriate for patients who are dating, as the big meals often associated with early dating can cause sildenafil to be less effective. Regarding which medication allows an erection to last longer, the clear winner is tadalafil. Sildenafil remains effective for four to six hours, while tadalafil will enable patients to achieve erections up to 36 hours after ingestion, an effect usually seen in younger patients or lesser degrees of ED.

Serious Side Effects

In both cases, the drug does not increase desire, instead allowing for a better erection when the desire is present. As with any medication, side effects are associated with both sildenafil and tadalafil. Generally, however, both drugs are well tolerated and have few severe side effects. Patients taking sildenafil may experience headaches, nausea, flushing, stuffy nose, and on occasion, indigestion, or dizziness. Patients may also develop a blue hue to their vision. As the first oral medication for ED, Viagra became incredibly popular.
