I have been having pain in my left arm and shoulder and left side of head along with rapid heartbeat and bp is around 189/135 ? Its started around 2am lastnight then went away but has happened two more times just recently tonight. I am on bp meds lisinapril 40mil. and take furosemide 40mg. once a day ? Is it safe to take a half pill of lisinipril to get bp lower ?
Hello, You can take additional lisinopril. If blood pressure is persistently high, you have to consult a physician and add additional Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further.
