It's crucial for patients to consider these factors as they navigate their treatment regimens.

Common drug conflicts (refer to Health Canada advisories)

Theophylline may not play nicely with certain common medications, and these interactions are highlighted in advisories from Health Canada. For instance, antibiotics like erythromycin and fluoroquinolones can elevate theophylline levels in the bloodstream. This raises concerns for toxicity, with potential side effects worsening when combined with medications prescribed for heart conditions. Awareness of these interactions can help patients manage their health more effectively.
