How does nifedipine interact with over-the-counter cold and flu medications and what precautions should patients take to avoid adverse reactions?
1. Nifedipine may increase heart rate when taken with some decongestants in OTC cold medications. Monitor blood pressure and heart rate carefully.
2. Combining nifedipine with OTC cold meds containing pseudoephedrine can raise blood pressure. Patients should opt for pseudoephedrine-free versions.
3. Patients on nifedipine should avoid OTC cold and flu drugs with decongestants, as these can enhance cardiovascular effects, increasing hypertension risk.
4. Using nifedipine with decongestants like phenylephrine can elevate blood pressure. Choose cold medications that are free of decongestants to avoid this issue.
