Omeprazole may raise the risk of pneumonia, especially in the elderly and those with prior lung issues. Patients should maintain good hygiene, stay current with vaccinations, and monitor respiratory symptoms closely.

Patients on omeprazole, especially if immunocompromised, might be more prone to pneumonia. They should avoid crowded places, practice regular handwashing, and consult healthcare providers for influenza and pneumococcal vaccines.

Long-term use of omeprazole can increase susceptibility to pneumonia. High-risk individuals should manage their overall health vigilantly, avoid smoking, and consider discussing alternative treatments with their doctor.
