Unexpected Side Effects of Common Medications You Should Discuss With Your Doctor

13. Heartburn Meds and Vitamin Deficiency: A Hidden Trade-Off

Acid reducers like H2 blockers and PPIs can bring much-needed relief from chronic heartburn—but they can also silently sap your body’s ability to absorb key nutrients like vitamin B12, magnesium, and iron. Over time, this can lead to symptoms like fatigue, muscle cramps, and even cognitive issues. The risk increases with long-term use. If you're taking these medications regularly, ask your doctor about routine nutrient checks or whether supplements might be needed. Sometimes, easing the burn can mean a slow burn on your health—so it pays to be proactive.

14. Asthma Inhalers and Oral Thrush: The Fungus Among Us

Inhaled corticosteroids are lifesavers for asthma and COPD, but they can also create the perfect conditions for oral thrush—a fungal infection that causes white patches, soreness, and a strange taste in the mouth. The culprit? Residual medication left in your throat and mouth after inhalation. The fix is simple but often overlooked: rinse your mouth thoroughly after each use. If you notice recurring mouth issues while on inhalers, it’s worth bringing up with your doctor to adjust dosage or delivery method.
