What is the difference between Montek LC and Montek FX, and should I be worried that I have been taking Montek FX instead of my prescribed Montek LC for the past month?
Both Montek LC and Montek FX contain montelukast to help manage your allergies. The only difference is the antihistamine paired with it: Montek LC has levocetirizine, while Montek FX has fexofenadine. Both antihistamines work very similarly to relieve allergy symptoms, though fexofenadine is often less drowsy. Since they serve a highly similar purpose, taking Montek FX for a month is unlikely to cause any harm. However, to ensure your treatment is exactly as intended, please consult your doctor to discuss safely switching back to your prescribed Montek LC.
