Does Miralax Raise Blood Pressure (Page 2) (Top voted first)

I've never had a blood pressure issue and since taking MiraLAX for a week for constipation my lood pressure was 166/104! Could it be the MiraLAX?

REPORT

I cannot take Miralax nor can 2 of my friends because it raises our blood pressure too much. One friend had to go to the ER after taking it. My husband takes it every day with no problems, but he had a heart attack after taking Linzess. Everyone is different. Just be careful, just because it isn’t listed as a side affect doesn’t mean it won’t happen.

Yes my husband too, 180’s / 100, every time he used it. When he stopped it went back to normal. Never again.

I will never take Miralax again. I am eating prunes every day and seems to help and do not have blood pressure problems.

I just got out of the hospital. I was given some very expensive tests due to high BP. The doctors found nothing but they gave me a BP medication that I plan on taking tonight. I took my Miralax and I can feel my BP is high. It was recommended for me because I have a SCI and I had to have a colostomy. This is very upsetting. Now I owe a huge medical bill. It seems like a lot of people have this reaction. Why does'nt Miralax have a warning?

Re: Linda Hon (# 17)

After taking miralax for about ten days, I had my blood pressure rise so much I could feel something going on inside that alarmed me. I checked my pressure and it was 180. I’m always 120. I took an 81 mg aspirin and it slowly came down. Have stayed off the miralax and am totally back to normal. I did go to my doctor who ordered blood tests, etc. all came back normal. I would never have suspected the miralax but my husband began searching the rare side effects and found hbp among women 65+ I had ruled everything else out…the Miralax was the lone culprit. My dr wasn’t aware of this.

Yep, my blood pressure has spiked on miralax too. I'm having to take BP meds to bring it down. It got to 165/110 last night. Also be aware of certain stomach teas with licorice.

The last time I checked, it is not listed as a side effect but it definitely raised my BP and many of my friends. Doctors don’t believe it when it isn’t listed.

I did the same pre colonoscopy prep. Couldn’t figure out why I was getting a pounding headache and flushing. My BP is usually 118/60, but it went up to 165/90! Glad I found this forum, now I know it was the Miralax! Hoping it goes back down after the procedure tomorrow

Re: John (# 42)

I just went through the same thing. l did the prep on Tuesday & Wednesday. I went to get the procedure and they sent me home. My BP went from 140/75 to 210/110. So I prepped for nothing. My BP is still high at 175/99 and I’m waiting for my cardiologist to call me back.

I am with you, Sam! The exact same thing happened to me. I ended up hospitalised and waited to CAT scan and an MRI. I have a $3000 deductible on my insurance that Just started over so now I have to pay out all because of the MiraLAX

I had a urinary catheter inserted after prostate operation and was told to take Miralax and yes the Miralax worked to give me soft stools, but it also spiked my blood pressure to 170/100. Had to stop it.

Nadine, I stopped the Miralax and I feel MUCH better. I was prescribe a small dose of Lisinopril 5MG daily for my BP and I will stay on that since my BP has been a bit high for the last few years and my family history includes some significant heart problems. I too will be using prune juice to help with constipation. I have an end colostomy because my anal cavity was paralyzed due to my SCI.I am tired of trying medications that hurt more than they help. Natural substances seem the better choice for me. I am 61.

Are you taking anything else that could raise your blood pressure if it accumulates in your system too much? Sometimes when you’re constipated you get issues with stuff staying in your system too long.

This just happened to me. I have an aneurysm so must closely watch my BP and it has been around 110/70 for weeks. I took one packet of Miralax and 2 hours later it was 150/90! It was high for the next 48 hours (topped at 170/90 one morning, very scary!) and is finally coming down today. I will never take a PEG-3350 medication again. BP this high could rupture my aneurysm. I wish more doctors knew about the possibility of dangerously high BP from this substance.

Re: NorthernLiz (# 44)

A follow-up to this: My BP finally came down after 8 days, and with it the constipation came back. After getting badly bloated and plugged up again I took 1 Senokot in the evening.

2 hours later my BP went up 25 points and continued to be high all the next day (while the laxative worked). It topped out at 160/89. Finally the day after that (today) it came down again (so far).

I am newly on metoprolol, a beta blocker, and never had constipation issues until I was on it. Since I've now experienced a significant rise on 2 different laxatives of 2 different types (osmotic and stimulant) I am thinking now that it is some interaction with the beta blocker and the bowel signaling causing this and not the laxative itself.

5 years ago I used a PEG-based colonoscopy prep that I had no issues with. I wasn't on BP meds at the time nor a beta blocker.

I would be very interested in hearing if anyone else having this issue was also on a beta blocker and if so, which one.
