Hi and thanks for the query,
That was the expected side effect of the drug. Its a good sign the symptoms were well controlled by Beta blockers. With an uneventful evolution, there is really no need to worry. iT would be interesting to know if this is the first time you are experiencing these symptoms or not? If it is, then, it would be important to stay calm and observe the symptoms for a few days. Persistence should then warrant a consultation with your primary care
physician. A complete neurological examination and serum electrolytes especially for Calcium, Magnesium
and Potassium shall be key orientation markers in making an appropriate diagnosis and management scheme. For now, be calm.
thanks and best regards
