Sometimes it ceases for a few days, and then it starts up again. I consulted my Dr. about this and he changed my medication with disasterous results. I am finally back on Ziac, but the trembling still continues. No one can seem to find a reason for this. This could be referred pain from your stomach, but, I can't figure any reason for this drug to cause any GI problems which would feel like a tremor.
Occasional patients do have nausea on beta blockers.
Beta blockers are not affected. By the way, Ziac is a combination of beta blocker and a diuretic-not a pure beta blocker. The rapid heart rate is clearly Ziac withdrawal since this is a drug that tends to slow the heart rate due to the beta blocker in the medication. Nervousness, shakiness, sleeplessness are less common. These may represent a panic attack or anxiety.
