I have high blood pressure and I am supposed to take 50 mg of Atenolol per day. I forgot I had already taken it today, and I accidentally took two (100 mg.) I checked my blood pressure and it is 110 over 68. I am starting to feel dizzy and I feel like my heart is racing. I googled Atenolol overdose and some websites said loss of life, but I wasn't sure how severe of an overdose they were talking about. Is this serious? Should I go to the emergency room?

How far apart were the two doses you took?

About 30 minutes

How long ago?

The first one 45 min. to an hour ago, so the second one 15 or 30 minutes ago

Time to go to the ER. You need to have this monitored as it can be life threatening.

I called the Emergency Room and they told me to call Poison Control. When I called Poison Control, they said that 100mg shouldn't be a problem. Should I go to the emergency room anyway? Thank you so much for helping me by the way.

Hope this helps. My script calls for 50 milligrams also and I took 200.im used to taking 4 ibuprophen 200 milligrams each, in the morning and evening. Today I knew it was time to take my blood pressure medicine atenolol, 50 milligram. So I did, but for some stupid reason, geuss I just had too much on my mind, I took 4. wound up going to er where they monitored me for 3 hours. Said I was fine and sent me home. I feel fine other than being a little sleepy. Had a couple of drinks which the doc said should be fine. So I'm sure you , only taking one extra dose, should be just fine. Just keep an eye on yourself, and if you feel a little weird, then go to the er. Weird as in chest pain or dizziness like your about to pass out.
