Cialis (tadalafil) vs. Viagra (sildenafil)
Viagra is a drug used for the treatment of erectile dysfunction. It helps men achieve and maintain an erection when stimulated.
Only in the U.S. more than 7 million men used Viagra to improve their sexual performance. Viagra is effective for 82% of the patients who use it, improving their erection. This means that 4 out of 5 couples that have tried Viagra have regained their sexual activity.
Viagra comes in different doses: 25 mg, 50 mg, 100 mg. Do not take more pills than the doctor prescribes you and don’t exceed one pill per day. If you are older than 65 years, either you suffer from severe kidney or liver problems, your doctor can recommend you to start with a minimal dose.
Viagra contraindications and side effects
Not anyone can use Viagra. If you are taking medicine containing nitrates – it makes no difference if you take it regularly or only when needed – you must not use Viagra. If you do so, your pulse may suddenly drop to a level that might threaten your life. You can get dizzy, faint, or even worse, suffer a heart attack. This pill is only for patients with erectile dysfunction problems. It mustn’t be use by women and children.
Any medicine produces side effects in some users. Usually the side-effects are not dangerous and don’t last for more than a few hours. Some of them appear when a high dose is used. The common side effects revealed during studies in Viagra’s users were: headache, stomach ache, dizziness, flushing, urinary tract infection, diarrhea, rash, temporary visual disorders (blurred vision, sensitivity to light, color perception changes).
Abnormal vision and stomach aches were usually encountered in patients using 100 mg doses.
