Can you tell me if it's okay to take Allegra M long-term? Every time I stop after a couple of days, I get a runny nose, itchy and watery eyes. It's been really helpful for the past two years, but I'm worried if using it for a long time is safe. What do you think?

Understanding Allegra M and Its Components

• Montelukast is a leukotriene receptor antagonist, and Fexofenadine is an antihistamine. Together, they manage allergy symptoms by reducing inflammation and blocking histamine effects.

Long-Term Use Considerations

• Continuous use for two years can be beneficial for symptom control but requires medical supervision to monitor for potential side effects and ensure ongoing efficacy.

Potential Side Effects of Long-Term Use

• Common side effects include headache, dizziness, and fatigue. Rarely, mood changes or liver issues may occur. Regular check-ups are advised.

Managing Symptoms When Stopping Medication

• Symptoms may return due to underlying allergies. This could indicate a need for ongoing treatment or alternative therapies.

Recommendations and Next Steps

• Consult an allergist for personalized advice. They can explore alternative treatments and adjust your management plan as needed.

Relevant Medical Specialties and Tests

• Consider seeing an allergy and immunology specialist. Tests like skin prick tests or blood tests can reassess your allergy status.
