How They Work
Both block an enzyme (PDE5) that ends an erection, so blood stays in longer when you are aroused. Neither causes an erection on its own; you still need stimulation.
Sildenafil
Take 30 to 60 minutes before. Works four to six hours. Food, especially a fatty meal, slows it down. Side effects: flushing, headache, stuffy nose, a blue tint to vision in some men. Generic Viagra.
Tadalafil
Take 30 minutes to two hours before; works up to 36 hours. Food does not matter much. A low daily dose (2.5 to 5 mg) keeps you ready any time and also helps urinary symptoms from an enlarged prostate. Side effects: headache, back ache, flushing. Generic Cialis.
Who Picks Which
Planned, occasional: sildenafil. Spontaneous, or several times a week: daily tadalafil. Many men try both over two months and keep the one that fits.
