This is a follow up to last night’s post on medication costs.
Preschool C. has been ill again. When I went to the chemist to pick up C.’s prescription, the assistant asked me if I wanted the chemist to recommend a probiotic.
Now, I was fascinated. First time I’ve even been asked that.
Had there not been a queue of people behind me, I would have loved to ask the chemist the following questions:
- Is this based on the current various international guidelines for paediatrics that have found some/modest benefit for probiotics for children in certain cases?
- Is this the result of the large chain pharmacy’s upselling policy –and based more on popular marketing trends then actual science?
- What actual supplements (dose and species) are being suggested?
As there was a queue of people, I simply collected my child’s prescription. (I have a Blog for musing. I don’t need to be that person in a crowded shop!)
But if money is tight in your house and this is just too much to afford, should you worry?The short answer is no – your child’s (and your) gut microbiome will likely be fine! Especially when we are talking about more commonly prescribed antibiotics used in the community.
Let’s give you some more information.
The current overall evidence from meta-analysis (meaning when they combine the data from several good quality studies) suggests that there is moderate effect of probiotics for preventing diarrhoea from antibiotics. The studies found that the benefit from high dose (> 5 billion CFUs per day). It found that it could reduce the duration of antibiotic-associated diarrhea by almost one day. The benefit was found in particular with 2 species: Lactobacillus rhamnosus or Saccharomyces boulardii. How many days is it best to take them for? Well, studies ranged from days to weeks – so, experts aren’t sure yet. Experts agree while it probably has benefit, it does needs to be confirmed by a large well-designed multi-centered randomized trial. Those aren’t done yet. Gut health is a fascinating area of emerging research – and while marketing is jumping in, we certainly don’t have all the answers!
So, while many international guidelines do support use of probiotics, don’t lose sleep if this isn’t something you can afford at the moment.
What else to know?
If the supplements are a bit pricy (and some are), you can also consider foods that naturally have probiotics, even though most are unlikely to have the dose (measured as CFUs) or species recommended by current research: Yogurt, Kefir, Sauerkraut, Kimchi, tempeh, miso, buttermilk, and sourdough! You can choose to start it with the antibiotic, or on the last day of the antibiotic (experts aren’t sure which is best, yet!)
Most of the important things that help a happy gut don’t come in a bottle, anyway! Physical activity, getting outdoors, getting enough sleep, and a healthy diet rich in veggies may help support a healthy gut more than a supplement. Many veggies are “pre-biotics” or foods that support good gut health and microbiome (think of them as fertiliser for the gut) and include veggies like asparagus, peas, whole grains, bananas, onions, soya, and garlic.
What else to know? Probiotic and prebiotic supplements are not yet regulated by the HPRA (they aren’t medications). Also, antibiotic-associated diarrhoea is common (and can still happen even if you use probiotics!). Whether or not diarrhoea does happen, your child’s gut microbiome will usually recover on its own – over 2-4 weeks – on a healthy diet. Antibiotic-associated diarrhoea is one of the important reasons docs recommend avoiding antibiotics unless they are really needed.
