When can I expect a relief in my symptoms after starting Signolol for high blood pressure?
Signolol usually starts working within a few hours of taking it. However, it may take up to a week to see the full benefits of the symptoms of high blood pressure or heart conditions. You may not notice any difference, but that does not mean it is not working. For migraine, it may take a few weeks before you notice any difference, so keep taking the medicine.
