Loratadine is an antihistamine commonly used to relieve allergy symptoms such as sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat. The elimination half-life of loratadine, which is the time it takes for half of the drug to be cleared from the body, is typically around 8 to 24 hours in adults.
Based on the half-life, it can take about 1 to 3 days for loratadine to be mostly eliminated from your system. However, individual factors such as age, liver function, kidney function, and other medications being taken can influence the clearance rate.
It's essential to consult with a healthcare professional if you have concerns about how long loratadine may stay in your system or if you have any questions related to its use.
