Detailed Answer:
Hello!

Welcome and thank you for asking on HCM!

I understand your concern and would explain that this is not a toxic dose for atenolol. The maximal daily dose of this drug is up to 200mg daily.

So relax!

The main possible adverse effects related to this dose (if your body does not tolerate it well) could be low blood pressure and low heart rate, tiredness.

I recommend you to closely monitor your blood pressure and heart rate.

I would also recommend you to avoid physical activity during the day for the next 12 hours. After this period, the effects of this dose of atenolol will gradually disappear.

If your blood pressure or heart rate is too low, you should go to the ER.

Anyway, as I explained above this is not a really high dose of atenolol.

Hope you will find this answer helpful!

Greetings!

Dr. Iliri
