Bitter Almond and Ibuprofen, Oxycodone

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

Moderate

CNS DEPRESSANTS

Why this applies to Ibuprofen, Oxycodone

Ibuprofen, Oxycodone falls under CNS DEPRESSANTS — the group Bitter Almond interacts with.

Theoretically, bitter almond oil may have additive effects with other CNS depressants.
Bitter almond and its oil contain amygdalin, which is hydrolyzed to toxic hydrocyanic acid. This can cause CNS depression and respiratory failure.
Severity Moderate Likelihood Possible Evidence D

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

Combunox is a combo of ibuprofen plus oxycodone, and it's the oxycodone part that matters here. Oxycodone is an opioid, so it already slows your breathing and makes you drowsy. Bitter almond contains amygdalin, which your body can turn into cyanide, a poison that can also depress the nervous system and breathing. The worry is that stacking these two could deepen that slowing effect, leaving you very sleepy, foggy, or short of breath.

Honestly, this concern is theoretical, based on how the chemicals work rather than real reports in people taking both. The bigger issue is that bitter almond simply isn't safe to swallow at all. If you've been using it, please mention it to your pharmacist or doctor before mixing anything with your pain medicine.

“Combunox puts oxycodone, an opioid, together with the NSAID ibuprofen, and I want you to read this page carefully rather than skim it. Of the 356 supplements and herbs on file, 202 can raise your bleeding risk on top of what ibuprofen already does, and 78 can deepen the drowsiness and slowed breathing that come with oxycodone.”

About Bitter Almond

What is Bitter Almond?

Bitter Almond
  • Cough suppressant
  • Muscle spasms (antispasmodic)
  • Itching and skin conditions
  • Flavoring agent
  • Sedative or 'narcotic' effects

Bitter almond is a variety of almond that contains amygdalin, a compound the body converts into cyanide, making it potentially poisonous. Because of this serious toxicity risk, bitter almond should not be eaten or used internally, and there is no reliable proof it treats any health condition. If you want almond's nutrition, choose ordinary sweet almonds instead.
