None: The maximum recommended dosing frequency is once per day. Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. Higher than that and you could drop your blood pressure and cause serious problems.

100 mg: 100 mg is the maximum recommended dose. If it is no longer effective other issues might be present that need evaluated and alternative treatments could be needed. You should consult a urologist.
