AUTHORS ' CONCLUSIONS There is no clear evidence that probiotics are more effective than placebo at preventing infantile colic ; however , daily crying time appeared to reduce with probiotic use compared to placebo .
There were no clear differences in adverse effects .
BACKGROUND Infantile colic is typically defined as full-force crying for at least three hours per day , on at least three days per week , for at least three weeks .
Infantile colic affects a large number of infants and their families worldwide .
Its symptoms are broad and general , and while not indicative of disease , may represent a serious underlying condition in a small percentage of infants who may need a medical assessment .
Probiotics are live microorganisms that alter the microflora of the host and provide beneficial health effects .
The most common probiotics used are of Lactobacillus , Bifidobacterium and Streptococcus .
There is growing evidence to suggest that intestinal flora in colicky infants differ from those in healthy infants , and it is suggested that probiotics can redress this balance and provide a healthier intestinal microbiota l and scape .
The low cost and easy availability of probiotics makes them a potential prophylactic solution to reduce the incidence and prevalence of infantile colic .
OBJECTIVES To evaluate the efficacy and safety of prophylactic probiotics in preventing or reducing severity of infantile colic .
Lactobacillus reuteri (American Type Culture Collection Strain 55730) Versus Simethicone in the Treatment of Infantile Colic: A Prospective Randomized Study
OBJECTIVE . The goal was to test the hypothesis that oral administration of Lactobacillus reuteri in a prospect i ve r and omized study would improve symptoms of infantile colic .  METHODS . Ninety breastfed colicky infants were assigned r and omly to receive either the probiotic L reuteri ( 108 live bacteria per day ) or simethicone ( 60 mg/day ) each day for 28 days . The mothers avoided cow 's milk in their diet . Parents monitored daily crying times and adverse effects by using a question naire . RESULTS . Eighty-three infants completed the trial : 41 in the probiotic group and 42 in the simethicone group . The infants were similar regarding gestational age , birth weight , gender , and crying time at baseline . Daily median crying times in the probiotic and simethicone groups were 159 minutes/day and 177 minutes/day , respectively , on the seventh day and 51 minutes/day and 145 minutes/day on the 28th day . On day 28 , 39 patients ( 95 % ) were responders in the probiotic group and 3 patients ( 7 % ) were responders in the simethicone group . No adverse effects were reported . CONCLUSIONS . In our cohort , L reuteri improved colicky symptoms in breastfed infants within 1 week of treatment , compared with simethicone , which suggests that probiotics may have a role in the treatment of infantile colic
