Key takeaways
Olopatadine (Pataday) and loratadine (Claritin) are both over-the-counter antihistamines used to treat allergy symptoms, but they have some key differences. Olopatadine is an eye drop used to relieve eye itching and redness caused by allergies, while loratadine is taken orally to treat a broader range of allergy symptoms, such as runny and itchy nose. Olopatadine is applied directly to the eyes once or twice daily, depending on the strength, whereas loratadine is taken by mouth once daily. Olopatadine can cause side effects like blurry vision and dry eye, while loratadine may cause headaches and tiredness. Additionally, Olopatadine is suitable for children over 2 years old, while loratadine can be used by children as young as 2 years old, but only in specific formulations. Lastly, Olopatadine requires you to remove contact lenses before use, whereas loratadine should be used with caution in people with phenylketonuria (PKU).
