Hello... I am a 29 year old woman. 5' tall 116 lbs and lead a very healthy lifestyle. My blood pressure is typically really good - 110's/70's. I have been on amoxicillin since last Monday for tonsillitis. I've been monitoring my BP this week b/c I randomly took it on Wednesday and it was higher than usual (128/82). My doctor said that was probably just because I was still sick. Since then, it has gone up pretty siginificantly. I've taken it the past 3 days and it's ranged from the 140's - 150's / 80's - high 90's. This morning it was 150/82. I'm not sick anymore, and I just find it odd that is has sky-rocketed like this so suddenly and doesn't seem to be going down. I feel crazy for being so worried about it... but I just want to make sure this is nothing to freak out about! Thanks!

Thanks for the query.
Your systolic blood pressure is raised( from 110 to 150) more than affection of diastolic blood pressure.
The commonest causes of such increase are anxiety/stress , pain or fever.
So in your case the fact that you are worried about your bp is causing more harm.
I would advise you please avoid worrying over this situation and soon you are likely to have your bp come back to normal.
Hope I have answered your query.

Thank you... I had a feeling that may be the case. However, my diastolic has gone as high as 98 over the course of the last few days. Is that something to worry about? Also, are these reading so high that I should be talking to my doctor about it? I just don't understand what caused the huge increase in the first place... I wasn't worried about it when I first took it and discovered it was higher than usual.

Thanks for the follow up.

Any illness causing inflammation, pain, fever and several medications can cause blood pressure changes.

So it is possible that the illness and the anxiety could have increased your blood pressure in the first place. However, if these readings persist, I would suggest that you consult your treating physician who can evaluate you and start appropriate therapy.

As of now, you need to stop worrying and wait and watch for a couple of weeks. In all probability, your blood pressure should go back to normal.

I hope I have answered your query. Please accept my answer if you have no further queries.

Wishing you good health.
