Interaction report

Saffron and Acetaminophen, Butalbital, Caffeine, Codeine

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Saffron interacts with whole categories of medication. Acetaminophen, Butalbital, Caffeine, Codeine falls into 2 of those categories, so it can interact with Saffron in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Acetaminophen, Butalbital, Caffeine, Codeine

Acetaminophen, Butalbital, Caffeine, Codeine falls under CNS DEPRESSANTS — the group Saffron interacts with.

Theoretically, concomitant use of saffron and CNS depressants might have additive sedative effects.
Clinical research shows that taking saffron extract 60 mg orally daily for 26 weeks can cause drowsiness and sedation. Animal research suggests that adding saffron to hexobarbital further increases sleeping and slows motor activity.
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

This combination pill already has two ingredients that can make you sleepy: butalbital (a barbiturate) and codeine (an opioid). Saffron, especially in concentrated supplement doses, has been linked in some studies to drowsiness and a calming, sedative effect. So the concern here is simple addition. Stacking saffron on top of a medicine that already slows the brain could leave you more groggy, dizzy, or foggy than usual, and in theory could deepen slowed breathing.

Keep in mind this is a theoretical caution based on how these things work, not strong human proof, and the saffron you sprinkle in food is unlikely to matter. Concentrated supplements are the real question. Before pairing them, check with your pharmacist or doctor.

Moderate

CAFFEINE

2 of 2

Acetaminophen, Butalbital, Caffeine, Codeine also falls under CAFFEINE.

Theoretically, saffron might inhibit the metabolism of caffeine.
A small clinical study suggests that taking saffron powder 300 mg in 150 mL water daily for 5 days and then taking caffeine 200 mg seems to reduce caffeine metabolite levels in the saliva and urine in males, but not females. Theoretically, this may be due to the inhibition of cytochrome P450 1A2 by saffron.
Severity Moderate Likelihood Possible Evidence B

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

This combination pill includes caffeine, and that is the piece saffron may touch. A small study found that saffron seemed to slow down how the body clears caffeine, likely by blocking an enzyme called CYP1A2. If caffeine hangs around longer, you might notice more jitteriness, a racing heart, trouble sleeping, or feeling on edge, especially since you may already be getting caffeine from coffee or tea.

I want to keep this in perspective. The evidence is early and somewhat theoretical, the effect was modest, and it showed up in men but not women. Saffron sprinkled in food is very unlikely to matter; concentrated supplement doses are the bigger question. Saffron does not change the codeine, butalbital, or acetaminophen parts here. If you take a saffron supplement, just give your pharmacist a heads-up.

About Saffron

What is Saffron?

Saffron
  • Depression and low mood
  • Anxiety
  • PMS symptoms
  • Memory and cognition
  • Eye health (age-related macular degeneration)

Saffron is a costly spice that has shown promise in early studies for mild-to-moderate depression and some mood and PMS symptoms, but most research uses small trials, so results are not definitive. It is generally well tolerated in food and small supplement amounts, but high doses can be harmful and it should be avoided in pregnancy. Talk to your pharmacist or doctor before using saffron supplements.
