It sounds like you are experiencing typical allergy symptoms such as a runny nose, itchy eyes, and sneezing, which can be quite uncomfortable. A medication called Montair FX, which combines Montelukast and Fexofenadine, is often used to relieve these symptoms by reducing inflammation and blocking allergic reactions.

• Montair FX Tablet helps control sneezing, runny nose, watery eyes, and itching by targeting the chemicals causing allergy symptoms.
• It is taken orally, with or without food, as prescribed by a doctor.
• Some side effects may include drowsiness, headache, or nausea, but these usually improve over time.
• Avoid taking it with indigestion remedies containing magnesium or aluminium at the same time, as this can reduce its effectiveness.
• If you experience mood changes or severe side effects, seek medical advice promptly.

Since this medication requires a prescription and proper dosing guidance, I recommend consulting an allergist or your general physician to confirm the diagnosis and get the right treatment plan tailored for you. If symptoms worsen or you develop breathing difficulties, seek urgent medical care.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
