What If I Take A Double Dose Of 100mg Losartan?

I took 100mg Losartan Potassium at 3pm but I think I may have taken one at 3 am also. I work shift work and I don't remember taking the 3 am dose. Will I have a problem taking a dose 12 hours apart?

Hi Craig,

From what I've researched, standard adult dosing for Losartan is considered to be anywhere from 25mg-100mg taken daily in one or two divided doses. However, the prescribing packet doesn't go on to mention any specific time intervals. Having said that, it seems to me like you're supposed to wait a full 24 hours after your last 100mg dose before taking anymore... So if you aren't sure about the time frame in which you took your last dose then I can't say there's a right or wrong answer... You may just have to be your own best judge through self monitoring of blood pressure levels. But for your own safety and peace of mind I'd still encourage you to discuss this with your prescribing doctor, who may have some other suggestions to add. You can always take more but you can't take less once it's ingested.

Hope this helps!
