5-htp and Ibuprofen, Hydrocodone

Moderate

CNS DEPRESSANTS

Why this applies to Ibuprofen, Hydrocodone

Ibuprofen, Hydrocodone falls under CNS DEPRESSANTS — the group 5-htp interacts with.

Theoretically, concomitant use of 5-HTP with medications that cause sedation might have additive effects.
In clinical trials, 5-HTP has been associated with drowsiness and somnolence.
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

The combo pill you're asking about (Ibucodone) pairs ibuprofen with hydrocodone, an opioid pain reliever that can make you sleepy and slow your breathing. 5-HTP isn't broken down by the same enzymes, so this isn't a metabolism problem. The concern is simpler: both 5-HTP and hydrocodone can cause drowsiness, so taking them together might stack that sedating effect.

In real life that could mean feeling extra groggy, foggy, dizzy, or having trouble staying alert. This is a theoretical concern based on how the two behave, not something proven in studies, so don't panic. Still, before you mix them, check with your pharmacist or doctor, especially if you'll be driving or you already feel sleepy on this medication.

About 5-htp

What is 5-htp?

5-htp
  • Low mood or depression
  • Anxiety and stress
  • Sleep problems
  • Migraine headaches
  • Fibromyalgia
  • Appetite or weight management

5-HTP is a compound your body uses to make serotonin, and people take it as a supplement hoping to improve mood, sleep, and headaches. Some early research is promising, but the overall evidence is limited and not conclusive. Because it can affect serotonin and may interact with medicines, talk to your pharmacist or doctor before using it.
