What Are The Side Effects Of Accidental Overdose Of Lisinopril?

default
Posted on Thu, 7 Jul 2016
Question: Hi Dr. I just spaced out and accidentally took a second dose of Lisinopril/HCTZ 25/20 about 5 hrs after my 1st dose (it's supposed to be 1x daily). Will I faint or croak? :) I actually have a regular Dr appt scheduled by chance in about an hour. Don't want to get yelled at. :) And I am a vet tech...I NEVER make mistakes like that!

I would recommend as follows:

Detailed Answer:
Hello!

Welcome and thank you for asking on HCM!

Regarding your concern, I would explain that this dose is supposed to lead to further decrease in your blood pressure.

What are your actual blood pressure values?

I recommend having some rest and avoid physical activity in the next hours, in order to avoid possible dizziness and fainting related to low blood pressure.

I would also recommend taking plenty of fluids to stay well hydrated.

Your symptoms will begin to disappear after 12 hours, and you will feel normal again.

You can go to your appointment with your doctor or not. It depends on the way you feel now and your blood pressure values.

Hope you will find this answer helpful!

Kind regards,

Dr. Iliri
