Atenolol stop working?

[Numberone1]

Is it possible that Atenolol can stop working? In the middle of the night over the last couple of days, I’m woken at night by a faster pulse, loud heart beat sound in my ears and headache. It feels like the Atenolol has run out of steam by that time after takingbit in the morning?

I doubt it , ask your GP ,maybe you need larger dose or different medication .

As said you need to speak to your GP. Things can change with time meaning a change of medication or dose. I do not know your drug regime but at one stage I developed palpitations in waking. It was caused by medication but none of the usual suspects. Give him a call today!

Atenolol has a half-life of 6-7 hours, whereas bisoprolol has a half-life of 9-12 hours, so the latter might be a better choice.

Atenolol is a rather out-dated beta-blocker now and the newer ones are preferred anyway.

You could also try taking it at night.

Talk it over with your GP

Thank you. I ended up in A and E yesterday and I will be seeing my go soon. Looks like my thyroid might be causing the problem.

I have the same experience, waking up and nightmares, fast pulse! After taking atenolol 50mg sleep like a baby without any problems since and no more horrible nightmares. What a relief since
