Summary
Only the mechanism-of-action (β-tubulin/microtubules/glucose/ATP depletion) and the stated larval activity against Echinococcus granulosus and Taenia solium are supported by the provided label text (12.4). The remaining numerous claims (indications, organism causes, pediatric use specifics, dosing/timing of effect/expulsion, side effects, and tablet administration/food guidance phrasing) are not supported by the label excerpts provided, and several are inconsistent with label instructions (e.g., 'with or without food').

Accurate Statements
Albendazole binds to the colchicine-sensitive site of β-tubulin inhibiting β-tubulin polymerization into microtubules; decreases microtubules in intestinal cells of parasites, decreasing absorptive function (especially uptake of glucose by adult and larval forms) and depletes glycogen storage; insufficient glucose results in insufficient ATP production and the parasite eventually dies.
Supported by FDA label 12.4 Microbiology (Mechanism of Action).
In the specified treatment indications, albendazole appears to be active against the larval forms of Echinococcus granulosus and Taenia solium.
Supported by FDA label 12.4 Microbiology (larval forms activity).
Unsupported Statements
Albendazole is used to treat certain types of parasitic worm infections in children.
The provided label excerpt does not list pediatric indications; only general statements about pediatric efficacy for hydatid disease/neurocysticercosis are shown (8.4) without supporting the broad 'certain types ... in children' framing.
Albendazole is used to treat neurocysticercosis in children.
The provided text mentions pediatric efficacy in neurocysticercosis (8.4) but does not explicitly establish indication-by-age; it only states efficacy appears similar to adults.
Neurocysticercosis is caused by pork tapeworm larvae.
No cause organism statement is present in the provided label excerpts.
Albendazole is used to treat cystic hydatid disease in children.
The provided text does not explicitly state albendazole treats cystic hydatid disease in children; only that hydatid disease is uncommon in infants/young children and pediatric efficacy in neurocysticercosis appears similar to adults (8.4).
Cystic hydatid disease is caused by dog tapeworm larvae.
No cause organism statement is present in the provided label excerpts.

No adverse reaction hair-loss statement is included in the provided label excerpts.
Hair loss from albendazole usually regrows.
No hair-loss/regrowth statement is included in the provided label excerpts.
Albendazole tablets can be chewed.
The provided label excerpt says tablets may be crushed or chewed and swallowed with a drink of water (2.1 Dosage), so this is partially supported; however the claim is embedded among many unsupported claims and is not verifiable as a standalone in this evaluation input. (See also administration section below for partial support conflicts.)
Albendazole tablets can be swallowed whole.
The provided label excerpt addresses crushing/chewing and taking with food; it does not explicitly state 'swallowed whole' in the provided text.
Albendazole can be taken with or without food.
Conflicts with provided label instruction that tablets should be taken with food (2.1 Dosage; patient counseling).
Taking albendazole with a fatty meal may increase absorption.
The provided label excerpt supports enhanced absorption with a fatty meal (12.3 Absorption), but the rest of the answer does not cite it and is therefore not fully supported as phrased generally in the broader set. (Mechanistic label support exists: 'coadministered with a fatty meal' enhances bioavailability.)
Liquid formulations of albendazole may be available for children who have difficulty swallowing tablets.
No label excerpt provided addresses liquid formulations or availability.
Albendazole tablets can be crushed and mixed with food.
The provided label excerpt states tablets may be crushed or chewed and swallowed with a drink of water; it does not state 'mixed with food.'
The dosage and duration of albendazole treatment depend on the specific type and severity of the parasitic infection.
The provided label excerpt states dosing varies depending upon indication and provides dosing by indication/weight/duration for hydatid disease and neurocysticercosis, but it does not mention 'severity' nor does it broadly support this generalization across all parasitic infections.
Albendazole should be used with caution in children with liver or kidney problems.
No pediatric liver/kidney caution statement is present in the provided excerpts. (Liver enzyme monitoring is present; renal function study limitations are present but do not state a caution instruction.)
Correct albendazole dosage is determined by a child's age, weight, and the specific infection.
The provided label excerpt provides weight-based dosing for hydatid disease/neurocysticercosis (2.1 Dosage) but does not state age is used for determining dosage.
If a child misses a dose of albendazole, it should be taken as soon as remembered.
No missed-dose instructions are present in the provided label excerpts.
If a missed dose of albendazole is close to the time for the next dose, the missed dose should be skipped.
No missed-dose instructions are present in the provided label excerpts.
If a child misses a dose of albendazole, the regular dosing schedule should be resumed.
No missed-dose instructions are present in the provided label excerpts.
A missed dose of albendazole should not be doubled to catch up.
No missed-dose instructions are present in the provided label excerpts.
Albendazole has been investigated for other uses including certain types of tumors.
The provided label excerpts include carcinogenicity studies (13.1) but do not support 'investigated for tumors' as an indication/usage claim.
Albendazole has been investigated for other uses including fungal infections.
No fungal infection investigation statement is present in the provided label excerpts.
Use of albendazole for tumors or fungal infections in children is not standard.
No statement about standard-of-care or use status for tumors/fungal infections is present in the provided label excerpts.

Contradiction with label instruction to take albendazole tablets with food; many other claims are unsupported or not present in the provided label excerpts.
Suggested Improvement
Limit claims to what is explicitly supported by the provided label text (e.g., 12.4 mechanism and larval activity against E. granulosus/T. solium; 2.1 tablet administration with food; 2.1 crushing/chewing wording; 12.3 fatty meal increases bioavailability). Remove unsupported indications/causative organism statements, side-effect lists, onset/expulsion timelines, missed-dose rules, and generics/market-history statements unless corresponding label text is provided.
