I am a 34 y/o male and was at a clinic for an oral abscess. The RNP prescribed a 10 day regimen of amoxicillin 875mg 1 po bid. At the same time, she discovered that my BP was extremely elevated (200/110). I went to the ER, and by then it had dropped to 184/92. They performed an EKG and re-tested my BP; it had lowered to 164/93. They prescribed lisinopril 10mg 1 po q d. I have been taking the lisinopril for 5 days now, but my BP is still elevated and averaging approximately 190/100. I do not drink alcohol, I quit smoking 3 months ago and limit my sodium intake to 1200mg per day. Do I need to see my PCP for a possible dose / med adjustment, or is it normal for it to take time for the lisinopril to work?
