You must not take more than 1 tablet a day or exceed the dose prescribed for you. If you feel that your dose is not appropriate, that the effects of the medication are too much, or not enough, your doctor can alter your dose.
If you do take more than the recommended dose your risk of side effects, including serious ones, like low blood pressure or an erection that wouldn’t go away even after 4 hours, dramatically increases. If you do experience any side effects, particularly serious side effects, you should seek medical attention immediately.
