Interactions of Furosemide – What medications should be avoided?

Allowed and Disallowed Interactions of Furosemide

Furosemide is a medication that is used to treat conditions such as edema, high blood pressure, and congestive heart failure. However, it is important to note that furosemide can interact with certain medications, resulting in potentially harmful effects. Here are some of the medications that can interact with furosemide:

1. ACE Inhibitors:

ACE inhibitors, also known as angiotensin-converting enzyme inhibitors, are a group of medications commonly used to treat high blood pressure and heart failure. When taken together with furosemide, ACE inhibitors may increase the risk of low blood pressure and kidney problems. Examples of ACE inhibitors include:

  • Lisinopril: Lisinopril is a commonly prescribed ACE inhibitor used to lower blood pressure and protect the kidneys.
  • Enalapril: Enalapril is another ACE inhibitor that is often prescribed to treat heart failure and high blood pressure.

If you are taking furosemide and are prescribed an ACE inhibitor, it is important to closely monitor your blood pressure and kidney function.

2. Angiotensin Receptor Blockers:

Angiotensin receptor blockers (ARBs) are a type of medication used to treat high blood pressure and heart failure. Similar to ACE inhibitors, taking ARBs with furosemide can increase the risk of low blood pressure and kidney problems. Some common examples of ARBs include:

  • Losartan: Losartan is an ARB commonly prescribed to treat high blood pressure and protect the kidneys.
  • Valsartan: Valsartan is another ARB used to treat high blood pressure and heart failure.

It is important to inform your healthcare provider if you are taking furosemide and are also prescribed an ARB. Regular monitoring of blood pressure and kidney function is recommended in this case.

3. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs):

NSAIDs are a common class of medications used to relieve pain, reduce inflammation, and lower fever. When taken concurrently with furosemide, NSAIDs can decrease the effectiveness of furosemide and potentially worsen kidney function. Some popular NSAIDs include:

  • Ibuprofen: Ibuprofen is a widely used NSAID available over the counter to relieve pain and reduce inflammation.
  • Naproxen: Naproxen is another NSAID that can be purchased over the counter or by prescription for pain relief.

If you are using furosemide and are in need of pain relief or anti-inflammatory medication, it is recommended to consult with your healthcare provider regarding alternative options that do not interact negatively with furosemide.

In conclusion, while furosemide is an effective medication for conditions such as edema and high blood pressure, it is important to be aware of the potential interactions with other medications. It is essential to communicate with your healthcare provider and pharmacist about any other medications you are taking before starting furosemide to ensure safe and effective treatment.
