Moviprep and hashimotos

[Catlover3]

Hi. I have the delightful experience of a colonoscopy to look forward to. On the prep info it says that people with thyroid disease should check with their gp before taking the stuff. Has anyone used this prep?

[Staffsgirl]

Yes…no adverse effects. I checked with the colonoscopy team.

Thanks for your reply. I hate taking any medications as I have had problems in the past and am a proper worrier when it comes to taking anything new.

[Staffsgirl in reply to Catlover3]

Me too! Good luck with the procedure.

I've used Moviprep. It's full name is :

Macrogol 3350 with anhydrous sodium sulfate, potassium chloride, sodium bicarbonate and sodium chloride

bnf.nice.org.uk/drugs/macro...

According to that link the problem with having thyroid disease is an increased risk of arrhythmia.

Cautions

Cautions For macrogol 3350 with anhydrous sodium sulfate, ascorbic acid, potassium chloride, sodium ascorbate and sodium chloride

Debilitated patients; dehydration (correct before administration); impaired consciousness; impaired gag reflex or possibility of regurgitation or aspiration; moderate-to-severe cardiac impairment; patients at risk of arrhythmia (including those with thyroid disease or electrolyte imbalance); severe acute inflammatory bowel disease

...

More info on Moviprep can be found from drugs.com, a US site which I sometimes find more helpful than the BNF, and in this case it doesn't actually mention the thyroid specifically

You should ask one of your doctors if you are allowed to take electrolyte drinks along with the Moviprep. I'm thinking of something like Dioralyte which can be bought without prescription. If you do have a risk of arrhythmia then keeping electrolyte levels up could reduce the risk quite a lot I think, and it will definitely reduce the problem of dehydration.

I don't remember having a problem with Moviprep apart from finding it quite slow to act compared to other products I'd used in the past for bowel cleansing before surgery.

If you've never done bowel prep before you might not know this...

You usually get asked to drink quite large quantities of water as part of the bowel prep. As your bowel gets more and more empty what comes out gets more and more runny and also contains stomach acid which hasn't been neutralised. By the time you get to that stage your rear end is likely to be extremely sore. The stomach acid touching that sore area can be quite shockingly painful.

But this can be mostly avoided with the following two suggestions...

1) Buy yourself a good supply of toilets rolls impregnated with shea butter, aloe vera, coconut oil or something similar.

2) Every time you defecate, after you have finished rub some of this barrier cream on - available from supermarkets and chemists :

Good luck.

Thanks for your reply. I had a colonoscopy 9 years ago and it was a completely different preparation. You had to use a suppository which caused an explosive reaction along with a liquid diet for a few days before hand. It seems that each NHS area has there own rules, some say clear fizzy drinks are ok, some say there not! I will get some dioralyte and sip some in between bathroom visits! Not looking forward to this at all.

I've gone through quite a few bowel preps in my time, and the chemicals I have to prep with have changed over the years. The best one I found was starting with 10 (!!!) senna tablets all in one go, then some time later taking a lot of Picolax. It was a damn sight quicker than the Moviprep which has never worked well for me either for bowel cleansing or in lower doses for constipation.

I can't recall ever using suppositories, and by the sound of it I'm glad!

I think a low residue diet is sometimes recommended in the day or two before doing a bowel prep, but it is the most bland and boring diet I've ever had to swallow.

[Catlover3 in reply to humanbean]

My daughter had Picolax and managed fine with a low residue diet over 4 days. She just got very bored with eggs! I only have to do it for 2 days but I can't stand eggs nor Marmite, Bovril, Oxo. I'm supposed to be only on gluten free bread and I don't have dairy either. I'm not sure if I can have oat milk in my coffee! They don't mention plant based milks at all.

[humanbean in reply to Catlover3]

My knowledge of low residue diets is almost non-existent, so I have no idea whether oat milk is acceptable.
