Name a Beta Blocker that is the closest one to Levatol 20mg. Have taken Levatol for 12 yrs and it seems to be off the market, am worried about side effects since have such good luck with levatol ( no side effects and would like the closest one to it. have considered olive leaf extract ( I can regulate it ) ## I'd suggest asking your doctor about trying Labetalol, it is known to cause far fewer side effects than most others available. Its typical side effects, as listed by the FDA, may possibly include nausea, dizziness, headache and hypotension. Does anyone else have any suggestions?
