Learn what medications you shouldn't take with blood pressure medication and the potential side effects and risks of taking blood pressure medication with other medications and supplements. Follow safe medication practices for the best possible outcomes.


If you have high blood pressure, taking medication can be a crucial part of your treatment plan. However, taking other medications or supplements in combination with your blood pressure medication can be dangerous and lead to serious side effects or interactions. To ensure you get the best results from your blood pressure treatment plan, it’s essential to understand what drugs you shouldn’t take with blood pressure medicine. In this article, we’ll provide a comprehensive guide to common medication interactions to help you stay safe and informed.

Avoiding Dangerous Drug Interactions: What Not to Take with Blood Pressure Medicine

One of the most important reasons for avoiding medication interactions is to prevent any negative health effects. A drug interaction can occur when a medication affects the way your body processes another drug, resulting in changes to the effectiveness or side effects of either medication or both. With high blood pressure medication, there are specific drugs to avoid due to the way they interact in your body.

Blood pressure medicine interacts with other drugs because it can lower your blood pressure too much when combined with specific medications, causing hypotension, fainting, dizziness, or even a heart attack or stroke. Additionally, some drugs can increase the side effects of blood pressure medication, such as dizziness, headaches, or nausea.

The Importance of Knowing Your Medication: Common Medications to Avoid with Blood Pressure Medicine

Knowing which medications to avoid is critical to maintaining safe blood pressure levels. Before taking any medication, it’s essential to speak with your doctor or pharmacist to determine whether it’s safe to take with your blood pressure medication. Some common medications to avoid when taking blood pressure medication include:

  • NSAIDs (non-steroidal anti-inflammatory drugs) such as aspirin, ibuprofen, and naproxen
  • Steroids, including prednisone and cortisone
  • Antidepressants, such as amitriptyline, fluoxetine, and venlafaxine
  • Cold and flu medications that contain decongestants, such as pseudoephedrine
  • Herbal supplements, such as St. John’s wort and ginkgo biloba

Each of these drugs interacts with blood pressure medication differently, so it’s important to understand how they may impact your health. For example, NSAIDs can reduce the effectiveness of your blood pressure medication and cause your blood pressure to rise, while certain antidepressants can lower your blood pressure to dangerous levels.

Are You Sabotaging Your Blood Pressure Treatment? Here’s What You Shouldn’t Take with Your Medication

Taking the wrong medication can sabotage blood pressure treatment and put your health at risk. Here are some additional medications to avoid when taking blood pressure medication:

  • Birth control pills or hormone replacement therapy
  • Diabetes medication, such as insulin or metformin
  • Cholesterol-lowering drugs, such as statins
  • Migraine medications, such as triptans
  • Non-drowsy allergy medications like cetirizine or loratadine

These drugs can cause changes in your blood pressure that may interfere with your medication’s effectiveness or result in dangerous interactions.

Medication Mix-Ups: The Dos and Don’ts of Taking Blood Pressure Medicine Plus Other Drugs

It’s essential to follow the dos and don’ts of taking blood pressure medication in combination with other drugs to maintain safe blood pressure levels:

  • Do follow the recommended dosage and usage instructions for all medications.
  • Do let your doctor know about any medications or supplements you’re taking.
  • Do take blood pressure medication at the same time every day.
  • Don’t take any new over-the-counter or prescription medications without consulting your doctor or pharmacist.
  • Don’t mix alcohol with blood pressure medication or other drugs.

Remember, proper management of your medication increases the chances of preventing negative drug interactions and helps you achieve better health outcomes.

Why Combining Blood Pressure Medication with Certain Over-the-Counter Drugs Can Be Dangerous

Besides medications, certain over-the-counter (OTC) drugs can also interact dangerously when combined with blood pressure medication, leading to significant health risks. Here are some common OTC medications to avoid when taking blood pressure medication:

  • Nasal spray decongestants like oxymetazoline
  • Weight loss supplements containing caffeine or ephedrine
  • Cold and cough medications that contain phenylephrine and dextromethorphan
  • Antacids containing aluminum or magnesium
  • Anti-inflammatory creams like diclofenac or ibuprofen

It’s important to talk to your doctor or pharmacist before taking any OTC drugs in combination with blood pressure medication to minimize potential side effects or interactions.

Enforcing Safe Medication Practices: What Drugs to Avoid When Taking Blood Pressure Medication

Safe medication practices are crucial to avoid dangerous drug interactions related to blood pressure medication:

  • Understand your medication instructions and follow them carefully.
  • Speak with your doctor or pharmacist before taking any new medications or supplements, including OTC drugs.
  • Keep an up-to-date list of all medications, doses, and directions and share it with your healthcare providers before receiving treatment.
  • Be mindful of changes in how you feel or side effects that may indicate a medication interaction.
  • Take medication in its original container, and never mix different medications in one container.


Staying informed about medication interactions is vital to maintain safe blood pressure levels and achieve better health outcomes. By knowing which drugs not to take with blood pressure medication and following safe medication practices, you can lower the risk of side effects, improve your blood pressure treatment, and prevent any negative health effects felt from the interactions of multiple medications.

Remember to speak with your healthcare provider before starting a new medication regimen or increasing dosages to avoid adverse interactions.
