It is safe to do this with any medication that is not time released.

Is there some reason, however, that you need to take a lower dosage?

Lisinopril is an ACE inhibitor that is used to treat high blood pressure and other cardiac conditions. If you have one of these conditions, it is very important that you take the proper dosage to keep them under control, so you shouldn't make any medication dosage adjustments, without checking with your doctor.

In addition, if you have been taking 40mgs and suddenly lower the dosage to 20mgs, you need to be aware that there will be rebound effects, which can include elevated blood pressure and elevated heart rate.


Is there anything else I can help with?

Verwon Says:

Wanzy, it can be done, if your doctor approves, however, you should be aware that the Hydrochlorothiazide in it is a diuretic, so taking half at night will probably result in your having to get up frequently and urinate.

That is why most doctors have their patients take it in the morning, to prevent their waking up to go to the bathroom, all night.



Are there any other questions?

was taking 10mg of lisinopril. Hadn't been in to see him and needed a refill. He ordered 40mg in stead of the 10 I had been taking. Called to find out why and the nurse just said he upped it. I personally would rather go to 20 at first. Thats why I want to cut it in half. Will it work like a 20mg if I cut it?

Lisinopril is supposed to be titrated slowly. That is the recommendation of the manufacturers and generally accepted practice. In my humblest of opinions, a doctor raising your dosage from 10mg to 40mg has made a mistake. Should have been 10mg to 20mg to 30mg to 40mg, with 2 weeks in between each titration.

My doctor prescribed HCTZ 25mg q am. This drug gives me horrible cramps in my legs and feet at night. Why is this?

Betsy Says:

The hydrochlorothiazide (HCTZ) portion of the medicine can cause excess potassium to be excreted with urination. Usually, ACE inhibitors (Lisinopril) when combined with the HCTZ, offset the excess loss of potassium that can be caused by this type diuretic. Though in your case, perhaps they are not completely canceling out eachother's effect on potassium. Try eating a banana or a potato before bed. Or taking a potassium supplement in the evening (20 mEq) but remember- with potassium- more is not better as it can cause other problems in excess.

My doctor told me to cut my 40 mg lisinopril in 1/2 which I did and it is 5 days later and my heart is beating too fast and my blood pressure is up to 133/86. What should I do now? I can't call my doctor until Monday and today is Saturday. Thanks.

I have been on Zestril - 40 mg - for three years. I had to stop it as we thought it was the med that gave me a rash. I have been off it for two months. I can now go back on it as we found the culprit. Can I go from not being on it to 40 mg? My doctor told me it was OK, but I am worried that it will affect me drastically as it did my neighbor who also stopped taking his bp meds and went on them again.

I have been on 20 mg Benicar. Was on 40mg. I want to know if I can safely split the 40 mg. Has anyone done this. My doctor said I could but in reading the label it says not to chew or crush the tablet. It does have a coating on it per bottle label. Splitting breaks that coating so the dose may not be accurate.
I was told by my doctors nurse a year our so back I could cut my Metoprolol ER in half when my dose was halved. In doing that I had problems and an ER visit likely due to having a different dose when tablet was split! My blood pressure went up and pulse rate also.
Appreciate and comments from someone taking Benicar or regards coated tablets. The 40mg is not scored in the middle either.
Thanks in advance for comments.

I was prescribed 1 20mg pill daily. I take it once daily. Can I split the pill in half and take 10 mg every 12 hours?

DJS Says:

I am guessing the 20 mg is about Benicar. Be sure the bottle label of tablets doesn't have ER after it. That means extended release. If it also says, like my Benicar, do not crush or chew I would definitely ask the pharmacist about it. It might have a costing that releases the dose over a 24 hour period of time.

I normally take 20mg of Lisinopril 1x/day and today I took it at 8:30pm and my B.P. 10minutes afterwards was 180/100. Can I take another 20mg tablet within a 2 hour period to drop the B.P. and be safe.

I would recheck my blood pressure a couple more times maybe 15 to 20 minutes in between. Also sit comfortably about 5 minutes before checking it. One reading might not be enough. Hope this helps. If your doc hasn't given you instructions to repeat the dose I might hesitate to do it.

Can I split a 40 milligram Lisinopril for one day? I normally take 40 milgms daily. However, I am awat and will not be home until later tomorrow. I did not bring an extra pill for the next day. Would it be okay to split in so I can drink half today and the other half tomorrow?

I would also like to see a reply to this question from an appropriate medical specialist ! I have started after it was suggested after a heavy nose bleed that required cauterisation, but this was by an ENT doctor who commented he had seen a number of patients who like me had the bleed after a hot shower ! I am taking a 20mg dose !

I take Lisinopril 5mg every morning. Ive been on it since February 2016. I'm out of my home state right now and my bp is staying between 149/78 w/ 99bpm to 158/67 w/ 102bpm. Today, Ive had a number of heart palps. In the last few weeks, it has dropped several times around 99/54 w/ bp of 99. It has never dropped that low. I'm 32 and I've never seen it below 120/75.

I'm overweight, but not morbidly obese, I don't have diabetes and I do exercise 3 days a week and walk 16-18 miles a week. I do have hemiplegic migraine and angina and have since 18 or 19/yo. Lots of stress, anxiety (0.5mg clonazepam, 20mg citalopram daily) and lack of sleep lately.

Should I be concerned about the fluctuations and can I take another 5mg if it doesn't drop in the next few hours?

Monies if it's a diuretic to get rid of fluid in the body some can make you go very often. Also I've read that some medications have a side effect that can cause you to have bladder frequency. I'd mention to my physician who prescribed it or call the office with your question. Hope this helps.
