4. Smoking or using tobacco
Smoking causes vasoconstriction, which is the narrowing of blood vessels, and increases heart rate. These effects oppose the action of amlodipine, which works by relaxing blood vessels to lower blood pressure. Continued smoking can diminish your medication’s effectiveness and increase cardiovascular risk.
Quitting smoking not only improves blood pressure control but also reduces overall heart strain and improves lung function. Even exposure to secondhand smoke can interfere with your treatment.
- Set a quit date and share it with supportive friends or family.
- Consider nicotine replacement therapies or apps recommended by healthcare professionals.
- Replace smoking habits with healthier alternatives like drinking water or using a stress ball.
5. Taking NSAIDs too often
Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen can reduce the effectiveness of amlodipine by causing fluid retention and increasing blood pressure. NSAIDs also add stress to your kidneys, which can further complicate blood pressure management.
Using NSAIDs frequently for pain or inflammation can make your blood pressure less stable and increase swelling. It’s important to discuss safer pain relief options with your doctor.
- Ask your healthcare provider about alternatives like acetaminophen.
- Use non-drug methods such as heat therapy, stretching, or rest for minor discomfort.
- Keep a list of approved pain relievers and avoid self-medicating with NSAIDs regularly.
6. Using St. John’s Wort or herbal supplements
St. John’s Wort and some other herbal supplements induce liver enzymes that metabolize amlodipine faster, potentially lowering its blood levels and making it less effective. Because these supplements are often perceived as natural and harmless, patients may not realize they interfere with their medication.
Disclosing all supplement use to your pharmacist or doctor is essential to avoid interactions that could undermine your blood pressure control.
- Inform your healthcare providers about any herbal products you take.
- Consider non-pharmacological mood support such as exercise or counseling.
- Never start new herbal supplements without medical guidance.
