The major competitors of Viagra are the same oral prescriptions belonging top the same class of drugs – phosphodiesterase-5 inhibitors or PDE-5 inhibitors. Levitra, Cialis, and Uprima are the most popular competitors of Viagra. Levitra and Cialis basically work in the same way as Viagra. Where to buy Viagra?

Another upside to Uprima is that it can be taken with medications that contain nitrates such as nitroglycerin (for heart problems). The pills causes side effect like headaches, nausea, fainting, and low blood pressure. Taking it with alcohol may worsen the side effects.
The PDE-5 competitors of Viagra have only minor differences in its chemical composition. This explains the differences in time it takes to work and wear off. Levitra takes 30 minutes to 1 hour to take effect while Cialis takes only 15 minuets. While the effects of Levitra, just like Viagra, takes 4 hours before it wears off, Cialis lasts for 24 to 36 hours. Viagra and its alternatives cause similar side effects and restrictions. Competitors of Viagra, just like the "little blue pill", should not be taken with medications that contain nitrates, some antibiotics, anti-viral and anti-fungal medications. Viagra and Levitra should not be taken on an empty stomach as it may cause abdominal discomforts but Cialis works well with or without food and alcohol.
