Cialis has been giving stiff competition to the older Viagra since its introduction 5 year earlier. Like any other medicine, Cialis too suffers from side effects. However, not all users suffer from the same side effects and to the same degree like other users do. Side effects do not require treatment and usually treat themselves in a little time or by consulting a doctor.
Cialis is perfectly suited for a few people that handle the drug perfectly well since the side effects are minor. Its side effects are in many cases lesser than those observed in people taking Viagra. The clinical trials of Cialis have been one of the most extensive ones tested in the past decade, with more than 6,000 men involved in the trials. About 2 percent of the people develop some sort of side effects after taking Cialis.
One of the most common side effects with Cialis is headache, which may last up to 36 hours after the consumption of the drug and can become severe. Men develop flu like symptoms like face flushing, which may last for a few hours. Blurred or hazed vision is another side effect seen in a few men because of the arteries to the eyes becoming constricted. Nausea, indigestion and vomiting are also seen in rare cases with combination with other drugs. Back pain is another side effect noticed in a few men. In a few cases, the back pains become severe at the first use, which leads them to discontinue the use of Cialis.
