If you are experiencing mild loose motions after taking AllerBio capsules, it may be a temporary side effect, as probiotics can sometimes cause changes in digestion when starting them. Take the capsule with food and drink plenty of water. If the loose motion is mild, you can continue taking it for a few more days to see if your body adjusts. However, if the symptoms persist, worsen, or become uncomfortable, it’s best to stop the capsules and consult your doctor to confirm if AllerBio is the cause and to consider an alternative.
