I’m Back On Cipro/2 Day After 4 Other Antibiotics. Prob

I’m back on Cipro/2 day after 4 other antibiotics. Prob is I’ve chronic leg pain & have been on tizanidine for yrs...I’m 83..But None while taking Cipro.
Here’s my prob: my bp is so low. 83/57; 73/55. I’ve taken losarten for yrs for hi bp. It’s dropped in past. But never like this. I’ve not taken losarten today, tho hi bp runs in my family.
Questions: Any prob w/Cipro? Its for cystitis which I’ve had for 5 weeks. Have been septic before & hospitalized for week.
