Conjugated Linoleic Acid (cla) and Ethacrynic Acid

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Ethacrynic Acid

Ethacrynic Acid falls under ANTIHYPERTENSIVE DRUGS — the group Conjugated Linoleic Acid (cla) interacts with.

Theoretically, taking CLA with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that a particular form of CLA reduces systolic blood pressure. Also, some clinical research shows that CLA enhances the blood pressure-lowering effects of ramipril, an antihypertensive drug.
Severity Moderate Likelihood Possible Evidence A

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: ethacrynic acid (Edecrin) is a strong water pill that lowers blood pressure partly by flushing extra fluid and salt out through your urine. CLA, in animal studies and a little bit of human research, seems to nudge blood pressure down on its own and may add to the effects of blood pressure medicines. So in theory, pairing the two could push your pressure a bit lower than expected.

If that happened, you might feel dizzy, lightheaded, or faint, especially when standing up quickly. Keep in mind this is mostly theoretical and based on limited data, so I don't want to alarm you. If you take CLA along with Edecrin, just mention it to your pharmacist or doctor and watch how you feel.

About Conjugated Linoleic Acid (cla)

What is Conjugated Linoleic Acid (cla)?

Conjugated Linoleic Acid (cla)
  • Weight loss
  • Improving body composition
  • Sports and muscle support
  • Reducing inflammation
  • General wellness

CLA is a fatty acid found naturally in meat and dairy, and supplements are usually made from safflower oil. While it is popular for fat loss and body composition, research results are mixed and any real-world effect appears small at best. It is likely safe for short-term use in most healthy adults, but talk to your pharmacist or doctor before starting it.
