Grapefruit juice may increase aripiprazole exposure; avoid concurrent intake. No other significant food interactions. Alcohol can enhance CNS depression; limit or avoid.
Take with a high-fat meal (≥40 g fat) to significantly increase oral bioavailability. Avoid grapefruit juice as it may affect drug metabolism. No specific dietary restrictions otherwise.
Pregnancy category C. First trimester: risk of major malformations not significantly increased based on limited data; however, neurodevelopmental effects uncertain. Second and third trimesters: neonates exposed in late pregnancy are at risk for extrapyramidal symptoms (EPS) and withdrawal syndrome including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, feeding disorder.
FDA Category C. First trimester: risk of skeletal abnormalities and embryotoxicity based on animal studies. Second and third trimesters: limited human data, but potential for fetal harm; avoid use unless benefit outweighs risk.
Aripiprazole is excreted in human breast milk; milk-to-plasma (M/P) ratio is approximately 0.5 to 1.0. Relative infant dose is estimated to be 1-3% of maternal weight-adjusted dose. Limited data; use with caution. Monitor infant for sedation, poor feeding, and abnormal movements.
Excreted in breast milk; M/P ratio not established. Use with caution, especially in neonates due to risk of bone marrow suppression.
No established pharmacokinetic data; however, pregnancy-induced physiological changes (increased plasma volume, renal clearance) may lower aripiprazole levels. Monitor therapeutic efficacy and consider dose adjustment if symptom exacerbation. No specific dose modification guidelines available; titrate based on clinical response and tolerability.
No specific dose adjustment recommended in pregnancy; pharmacokinetic changes not well studied. Use lowest effective dose and shortest duration possible.
Abilify (aripiprazole) is a partial dopamine agonist, which reduces the risk of extrapyramidal symptoms and hyperprolactinemia compared to full antagonists. Monitor for akathisia, especially during dose titration. QT prolongation risk is lower than with other antipsychotics; use caution in patients with cardiac disease. Avoid use in dementia-related psychosis due to increased mortality. Therapeutic effects may take 2-4 weeks; full response often requires 6-8 weeks.
Albendazole is a broad-spectrum anthelmintic that inhibits microtubule polymerization by binding to beta-tubulin. It is highly effective against Echinococcus granulosus cysts but requires prolonged therapy (e.g., 28-day cycles). Monitor liver function tests (LFTs) at baseline and every 2 weeks due to risk of hepatotoxicity. For neurocysticercosis, co-administer corticosteroids to reduce inflammatory reaction from cyst degeneration. Albendazole is pregnancy category C; avoid in first trimester and in women planning pregnancy within 1 month of therapy. Absorption is enhanced by a fatty meal; administer with a high-fat meal to increase bioavailability up to 5-fold.

No interactions on record
"Albendazole inhibits the CYP3A4-mediated metabolism of clemastine, leading to increased plasma concentrations of clemastine. This can potentiate the anticholinergic and sedative effects of clemastine, including dry mouth, urinary retention, constipation, and drowsiness. Patients may experience heightened central nervous system depression, especially with concurrent use of other CNS depressants."
"Ranolazine, a piperazine derivative antianginal agent, is a moderate CYP3A4 inhibitor. Albendazole is primarily metabolized by CYP3A4 to its active metabolite, albendazole sulfoxide. Coadministration increases albendazole systemic exposure by approximately 50%, potentially enhancing both therapeutic efficacy and dose-dependent toxicities, including hepatotoxicity and bone marrow suppression."
"Albendazole inhibits CYP3A4, the enzyme primarily responsible for the metabolism of lovastatin. This inhibition reduces lovastatin clearance, leading to elevated plasma concentrations and increased risk of statin-related adverse effects such as myopathy, rhabdomyolysis, and hepatotoxicity. Patients receiving this combination should be monitored closely for signs of muscle pain or weakness and liver enzyme abnormalities."
