Below is general information about the safety of the known ingredients contained in the product Acidophilus XTRA. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally and appropriately. Bifidobacterium lactis has been safely used alone or in combination with other probiotics in clinical trials lasting up to 12 weeks (92255,98502,105158,107572,107581,107586,110979,110985,110986,110992)(110993,110998,110999).
CHILDREN: LIKELY SAFE
when used orally and appropriately in children of most ages.
Bifidobacterium lactis has been safely used alone or in combination with other probiotics in infants and children for up to 15 months (3169,3458,92265,95381,95382,98736,105149,107582,107583,107585)(107587,107590,110984,110987,110988,110991,110994,110995). A combination probiotic containing B. lactis and Lactobacillus acidophilus (HOWARU Protect, Danisco) has been used safely for up to 6 months in children aged 3-5 years (16847). A specific combination of B. lactis, Bifidobacterium bifidum, and L. acidophilus (Complete Probiotic Platinum) has also been used safely for up to 18 months in children aged 4 months to 5 years (103436). In addition, in children ages 4-17 years, 1 billion CFUs of a 1:1:1 combination of B. lactis CECT 8145, Lacticasebacillus casei CECT 9104, and Bifidobacterium longum CECT 7347 has been used safely for 12 weeks (107531). There is insufficient reliable information available about the safety of B. lactis in preterm infants with a birth weight under 1000 grams. Cases of bacteremia have occurred rarely in preterm infants given other probiotics (102416,111610,111612,111613,111850,111852,111853). The US Food and Drug Administration (FDA) has issued a warning about cases of serious infections caused by probiotics reported in very preterm or very low birth weight infants under 1000 grams (111610). Similarly, the American Academy of Pediatrics does not support the routine administration of probiotics to these infants due to conflicting data on safety and efficacy (111608).
PREGNANCY AND LACTATION:
Insufficient reliable information available.
A meta-analysis of four clinical trials shows that taking probiotics during pregnancy increases the relative risk of pre-eclampsia by 85% when compared with placebo. Although the specific effects of Bifidobacterium lactis are unclear from this analysis, three of the included studies used B. lactis in combination with Lacticaseibacillus rhamnosus (105185). More information is needed to determine if certain patients are at increased risk.
LIKELY SAFE ...when used orally and appropriately. Lactobacillus acidophilus has been safely used as part of multi-ingredient probiotic products in studies lasting up to nine months (1731,6087,14370,14371,90231,90296,92255,103438,12775,107581)(110950,110970,110979,110998,111785,111793). ...when used intravaginally and appropriately. L. acidophilus has been used safely in studies lasting up to 12 weeks (12108,13176,13177,90265). There is insufficient reliable information available about the safety of non-viable, heat-killed L. acidophilus formulations when used orally.
CHILDREN: LIKELY SAFE
when used orally and appropriately in children of most ages.
Lactobacillus acidophilus has been safely used for up to 5 days (96887). Also, combination probiotics containing L. acidophilus have been used with apparent safety in various doses and durations. L. acidophilus has been combined with Bifidobacterium animalis (HOWARU Protect, Danisco) for up to 6 months in children 3-5 years old (16847), with Bifidobacterium bifidum for 6 weeks (90602,96890), with Bifidobacterium bifidum and Bifidobacterium animalis subsp. lactis (Complete Probiotic Platinum) for 18 months in children 4 months to 5 years of age (103436), and in a specific product (Visbiome, ExeGi Pharma) containing a total of 8 species for 3 months in children 2-12 years old (107497). There is insufficient reliable information available about the safety of L. acidophilus in preterm infants with a birth weight under 1000 grams. Cases of bacteremia have occurred rarely in preterm infants given other probiotics (102416,111610,111612,111613,111850,111852,111853). The US Food and Drug Administration (FDA) has issued a warning about cases of serious infections caused by probiotics reported in very preterm or very low birth weight infants under 1000 grams (111610). Similarly, the American Academy of Pediatrics does not support the routine administration of probiotics to these infants due to conflicting data on safety and efficacy (111608).
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately.
A combination of Lactobacillus acidophilus, Lacticaseibacillus casei, and Bifidobacterium bifidum has been used with apparent safety for 6 weeks, starting at 24-28 weeks' gestation (95416,98430).
LACTATION:
There is insufficient reliable information available about the safety of Lactobacillus acidophilus during lactation.
However, there are currently no reasons to expect safety concerns when used appropriately.
POSSIBLY SAFE ...when used orally. In the United States, most yogurt is made via bacterial fermentation with Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus (12778). Probiotic species similar to L. delbrueckii have not been associated with serious safety concerns when used appropriately in healthy adults. Most clinical trials have used L. delbrueckii in combination with other probiotics. It is unclear which specific dose and duration of use for L. delbrueckii as a probiotic may be most appropriate.
CHILDREN:
There is insufficient reliable information available about the safety of Lactobacillus delbrueckii as a probiotic in children of any age.
Cases of bacteremia have occurred rarely in preterm infants given other probiotics (102416,111610,111612,111613,111850,111852,111853). The US Food and Drug Administration (FDA) has issued a warning about cases of serious infections caused by probiotics reported in very preterm or very low birth weight infants under 1000 grams (111610).

Theoretically, taking Lactobacillus acidophilus with antibiotic drugs might decrease the effectiveness of L. acidophilus.
Details
L. acidophilus preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms (1740). Tell patients to separate administration of antibiotics and L. acidophilus preparations by at least two hours.

Below is general information about the adverse effects of the known ingredients contained in the product Acidophilus XTRA. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, Bifidobacterium lactis seems to be well tolerated by most patients.
Most Common Adverse Effects:
Orally: Diarrhea.
Serious Adverse Effects (Rare):
Orally: There is concern that probiotics may cause infections in some people.
Dermatologic ...In clinical research, two cases of rash, one with itching, were reported by patients taking a combination of Bifidobacterium lactis BB-12, Lacticaseibacillus paracasei F19, and Lactobacillus acidophilus La5. However, it is not clear if these adverse effects were due to B. lactis, other probiotics, or the combination, or if the events were idiosyncratic (90236).
Gastrointestinal ...Bloating and flatulence have been reported with probiotic use; however, these adverse effects have not been reported from ingestion of Bifidobacterium lactis in particular. When taken orally, B. lactis can cause diarrhea and other gastrointestinal complaints in children (3169,95381,105149). Gastrointestinal complaints including worsening diarrhea, abdominal pain, constipation, stomach burn, and flatulence have been reported rarely (110986,110999).
Immunologic
...There have been cases of Bifidobacterium bacteremia in critically ill patients (102416,107599).
These cases are rare and none seem to be due to Bifidobacterium lactis alone.
A specific preparation (NBL probiotic ATP, Nobel) containing B. lactis, Lacticaseibacillus casei, Lacticaseibacillus rhamnosus, Lactiplantibacillus plantarum, fructo-oligosaccharides, galacto-oligosaccharides, colostrum, and lactoferrin was found to be a significant risk factor for vancomycin-resistant Enterococcus colonization in premature infants. Although there was no direct link to determine causation, it was hypothesized that the probiotic mixture helped to mediate the acquisition and transfer of antibiotic resistance genes (96890).
General
...Orally and intravaginally, Lactobacillus acidophilus is generally well tolerated.
Most Common Adverse Effects:
Orally: Mild gastrointestinal adverse effects.
Intravaginally: Vaginal discharge.
Serious Adverse Effects (Rare):
Orally: There is concern that L. acidophilus may cause infections in some people.
Dermatologic ...Orally, in one clinical trial, a combination of Lactobacillus acidophilus La-5, Lacticaseibacillus paracasei subsp. paracasei F19, and Bifidobacterium animalis subsp. lacltis BB-12 was associated with two cases of rash, one with itching. However, it is not clear if these adverse effects were due to L. acidophilus, other ingredients, the combination, or if the events were idiosyncratic (90236).
Gastrointestinal ...Orally, taking Lactobacillus acidophilus in combination with other probiotics may cause gastrointestinal side effects including epigastric discomfort (90239), abdominal pain (90239,90291,111785), dyspepsia (90239), flatulence (107497,107520), bloating (107497,111785), diarrhea (111785), vomiting (107537), and burping (90239); however, these events are uncommon.
Genitourinary ...Intravaginally, cream containing Lactobacillus acidophilus has been shown to cause increased vaginal discharge in about 5% of patients, compared to about 1% of patients receiving placebo cream (90237). Vaginal burning was reported by one person using intravaginal L. acidophilus and Limosilactobacillus fermentum in a clinical trial (111781).
Immunologic ...Since Lactobacillus acidophilus preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. L. acidophilus has been isolated in some cases of bacteremia, sepsis, splenic abscess, liver abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis. Most of these cases are thought to be due to the translocation of bacteria from other locations in the body in which they occur naturally, such as the oral cavity and gastrointestinal tract (107543,111782,111792). L. acidophilus endophthalmitis has been reported rarely (111787,111795). In one case, it was related to intravitreal injections for age-related macular degeneration in a 90-year-old female with an intraocular lens (111787). In another, it occurred following cataract surgery (111795).

...Since Lactobacillus delbrueckii preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients.
Some lactobacilli species have been isolated in cases of bacteremia, sepsis, splenic abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis. These cases are thought to be due to the translocation of bacteria from other locations in the body in which they occur naturally, such as the oral cavity, or the gastrointestinal or urogenital tract, and not to dietary or supplemental intake (107543,110917,110918,110920,110921).
There are various cases of L. delbrueckii urinary tract infections (UTI) (112553,112557,112558). In one case, a L. delbrueckii UTI occurred in an 82-year-old male with benign prostate hyperplasia and related urinary retention (112553). Any use of probiotic products containing L. delbrueckii was not mentioned in this report. In one case, a 49-year-old male with a L. delbrueckii UTI reported daily yogurt intake, possibly fermented with L. delbrueckii. He had urinary retention in the absence of benign prostate hypertrophy and initially presented with acute bacterial prostatitis (112557). Most cases of UTIs have occurred in older females. An 85-year-old female with recurrent UTIs denied probiotic use; however, exposure via ingested foods was possible (112558).
