Are there any side effects with Caverta (Sildenafil Citrate)?
Side effects such as headaches, facial flushing and an upset stomach can occur, though these are most likely with higher doses of Caverta (Sildenafil Citrate). These side effects are usually mild and do not last longer than a few hours. You could also potentially experience temporary bluish or blurred vision or sensitivity to light. Should an erection last longer than four hours, you should seek medical assistance.
