About LASTACAFT

What is this medication?

Lastacaft is an ophthalmic solution containing the active ingredient alcaftadine, which is specifically used to prevent eye itching associated with allergic conjunctivitis. This condition often occurs when the eyes react to environmental triggers such as pollen, mold, animal hair, or dust. As an H1 histamine receptor antagonist, this medication is formulated to provide long-lasting relief for both adults and children aged two years and older.

The medication functions by inhibiting the effects of histamine, a chemical released by the body during an allergic reaction that leads to irritation and itching. It is typically applied as a single drop to each affected eye once every day, offering protection from symptoms for up to twenty-four hours. Patients should avoid touching the dropper tip to any surface to prevent contamination and should wait at least ten minutes after application before reinserting contact lenses.

Adverse reactions
6 ADVERSE REACTIONS The most common ocular adverse reactions, occurring in less than 4% of eyes treated with LASTACAFT ® , were eye irritation, burning and/or stinging on instillation, eye redness, and eye pruritus. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Allergan at 1-800-678-1605 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The most frequent ocular adverse reactions, occurring in less than 4% of eyes treated with LASTACAFT ® , were eye irritation, burning and/or stinging upon instillation, eye redness and eye pruritus. The most frequent non-ocular adverse reactions, occurring in less than 3% of subjects with eyes treated with LASTACAFT ® , were nasopharyngitis and headache. Some of these events were similar to the underlying disease being studied. 6. 2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of LASTACAFT ® . Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reactions include eye discharge, eye swelling, erythema of eyelid, eyelid edema, lacrimation increased, vision blurred, hypersensitivity reactions including swelling of the face or allergic dermatitis, and somnolence.
Use in pregnancy
8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies with LASTACAFT® in pregnant women to inform a drug associated risk. There are limited data with the use of alcaftadine eye drops in pregnant women. In embryofetal studies in rats and rabbits, oral administration of alcaftadine during the period of organogenesis did not produce maternal or embryofetal toxicity at clinically relevant doses. Advise pregnant women of a potential risk to the fetus and mother. LASTACAFT® should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus and mother. The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk in the U.S. general population of major birth defects is 2 to 4%, and of miscarriage is 15 to 20%, of clinically recognized pregnancies. Data Animal Data In rats, oral administration of 5, 20 or 40 mg/kg/day alcaftadine during the period of organogenesis (gestational days 6 – 16) caused maternal lethality at doses of 40 mg/kg. The no observed adverse effect level (NOAEL) for maternal toxicity was 20 mg/kg/day (an exposure 230-times higher than that at the maximum recommended human ophthalmic dose [MRHOD], based on AUC). There were no adverse embryofetal effects up to a dose of 20 mg/kg. In rabbits, oral administration of 10, 40 or 80 mg/kg/day alcaftadine during the period of organogenesis (gestational days 6 – 18) caused no maternal toxicity or adverse embryofetal effects up to a dose of 80 mg/kg/day (an exposure 8819-times higher than that at the MRHOD, based on AUC). Daily oral doses of 20 and 30 mg/kg/day alcaftadine administered to rats from Day 6 of pregnancy until Day 20 postpartum produced lower pup weights in offspring. No adverse effects in dams or offspring were observed at doses up to 5 mg/kg/day (a dose 286 times higher than the MRHOD, on a mg/m2 basis).
