I had to be put on a high dose of amoxicillin to clear up some bacterial infections and have been pondering the timing of implementing probiotics.

To my mind, there's not really any point in taking probiotics during the course of antiobiotic treatment as the beneficial bacteria will only get killed off and it may lessen the effectiveness of the antibiotic if it's having to kill of a lot of additional bacterial load (good or bad). It seems to me that I should start my probiotic regimen once I'm done with the antibiotics.

Does anybody else have any additional thoughts on this? Thanks!

Hi Crazybug,

Interesting question. My experience is to start loading double doses of probiotics prior to taking antibiotics, and continue throughout the antibiotic treatment. I have to admit that I've never thought the issue you brought up before.

I can't take amoxicillin at all anymore without generating c diff.

Good luck to you.

Antibiotics do kill both good and bad bacteria, but they do not kill ALL good and bad bacteria. So it probably is a good idea to take probiotics while taking antibiotics just to be safe that the bad guys do not get the upper hand.

Having said that I recommend also taking the probiotic good guy yeast Saccharomyces boulardii while taking antibiotics. It is a yeast and therefore immune to antibiotics. Very useful at keeping bad guys in check especially Clostridium difficile or C. Diff.
Male/59 DX ulcerative colitis Feb08, possible Crohn's colitis DX Mar10.
No Meds, allergic to Mesalamine. Remission since Mar10. Psyllium seed mixed with VSL3 especially helpful. Food journal instead of SCD.

Boswellia, turmeric, fish oil, S. Boulardii, resveratrol, multivitamin, extra D3, K2, C, high gamma E, magnesium, phos choline, glutamine, probiotics. Lots of fruit & vegetables(but no plums or kale), no soda, no HFCS, no trans fat, no shellfish, tea instead of coffee, watch gluten, few processed foods, no carrageenan.

It's vital to take probiotics especially while on antibiotics....yes basically antibiotics can kill everything, good and bad bacteria which is why it's essential to take a good probiotic daily and's best to try and take your probiotics at least 2 hours after you've finished taking your antibiotics for the day...key is to take a good quality probiotic and stay on them indefinitely...without probiotics women are more prone to getting yeast infections while on antibiotics.
bee propolis caps 500mg one cap twice/day
omegas 369 caps one cap twice/day
probiotics 10 billion cfu once/day
vitamins C-calcium ascorbate (easy on the gut) and vitamin A each once/day
Prodiem fibre supplement one cap before bed
I've also altered my diet (no junky stuff at all, processed, fast-foods, refined sugars, ect) and exercise regularly.
I went from 30+ bloody BM's/day with lots of lower back pain to an average of 5/day no bleeding no back pain and completely formed stools, still have severe urgency issues.

Thanks so much for your kind responses. I guess it couldn't hurt to go ahead and take the probiotics as I certainly don't want C.diff on top of everything else right now!

I would be interested in finding out how/where to purchase the Saccharomyces boulardii yeast. Is it available in a commercial product?

BTW - I had the worst colonoscopy experience yesterday that I've ever had. The anasthetics (even at the highest dost they could give me) didn't knock me out in the very least. I have vivid memories of the entire painful process. The nurse suggested that next time I go under complete anasthesia. Sorry just had to complain a bit to some folks who might understand. Unfortunately, my husband is not coping well with my illness and I just needed to get this off my chest. Thank you to all for being here and for being so knowledgeable and kind.

The timing is, take the probiotic 2 hours before you take the antibiotic, or 4 hours after.

Jarrow's sells S Boulardii at Whole Foods and health food stores. It can also be purchased online under the brand name Florastor.
