I am a 58 yo female. 5ft tall 170 lbs non smoker. I take supplements but no regular meds. I did receive a and oral dose of azithromycin (1 gram) 3 days ago to treat chlamydia. I do not use drugs of alcohol. My bp is very high today. Even after walking almost 4 miles this afternoon . Since then readings are ranging from 177/94 trending up ....now at 207/122. No symptoms other than fatigue. Is the anything I can do or take over the counter to bring my BP down quickly?
