SummaryClaritin (loratadine) is a medication commonly used to treat allergies such as hay fever and hives. It belongs to the second-generation antihistamine family of medications and is taken orally. While common side effects include dry mouth, sleepiness, and headache, serious side effects such as allergic reactions, seizures, and liver problems are rare. Loratadine is generally considered safe during pregnancy, but its effects have not been well studied in this population. Children under two years of age should not take this medication. Loratadine was patented in 1980 and first became available in 1988. It is listed as an essential medication by the World Health Organization and is available as a generic. In the US, it can be purchased over the counter and was one of the most commonly prescribed medications in 2020, with over 9 million prescriptions. |
