Melatonin and Hydrocodone, Ibuprofen

These two interact in 5 distinct ways. Each one is explained separately below.

Why Are There 5 Interactions?

Melatonin interacts with whole categories of medication. Hydrocodone, Ibuprofen falls into 5 of those categories, so it can interact with Melatonin in 5 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 5

Why this applies to Hydrocodone, Ibuprofen

Hydrocodone, Ibuprofen falls under CNS DEPRESSANTS — the group Melatonin interacts with.

Theoretically, taking melatonin might increase the sedative effects of CNS depressants.
Melatonin has sedative effects. Theoretically, concomitant use of melatonin with alcohol, benzodiazepines, or other sedative drugs might cause additive sedation.
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

Here's the deal with Vicoprofen, which pairs hydrocodone (an opioid pain reliever) with ibuprofen. The hydrocodone half already makes a lot of people drowsy and a bit foggy. Melatonin also nudges your body toward sleep. So when you take both together, the worry is that those calming, sleepy effects can stack on top of each other.

In real life, that might look like feeling extra groggy, lightheaded, or slow to react the next morning. I want to be honest though: this is a theoretical concern based on how each one works, not something proven to cause serious problems. Still, please check with your pharmacist or doctor before combining them, and don't drive until you know how the pair affects you.

SEIZURE THRESHOLD LOWERING DRUGS

2 of 5

Hydrocodone, Ibuprofen also falls under SEIZURE THRESHOLD LOWERING DRUGS.

Theoretically, taking melatonin with drugs that lower the seizure threshold might increase the risk of seizure activity.
Some clinical evidence suggests that melatonin may increase the frequency of seizures in certain patients, particularly children with neurological disabilities.
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

Here's the gist with Vicoprofen (that's hydrocodone combined with ibuprofen) and melatonin. The concern on file isn't about how the drug is broken down. Instead, it's that the hydrocodone piece, like many opioids, can slightly lower the brain's seizure threshold (the point at which a seizure becomes more likely). Melatonin has been linked, in a small number of cases, to more frequent seizures, mostly in children with existing neurological conditions. So in theory, pairing them could nudge that risk a little higher.

I want to be honest: this is a theoretical concern based on how these things work, not something most people will ever notice. If you have a seizure history, just check with your pharmacist or doctor first. Otherwise, this combination is usually fine for short-term use.

ANTICOAGULANT/ANTIPLATELET DRUGS

3 of 5

Hydrocodone, Ibuprofen also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, melatonin may have anticoagulant effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There are isolated case reports of minor bleeding and decreased prothrombin activity in people taking melatonin with warfarin (Coumadin). The mechanism, if any, of this interaction is unknown. Taking melatonin orally seems to decrease coagulation activity within one hour of dosing in healthy men.
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

Here's what matters for Vicoprofen, which combines hydrocodone (an opioid pain reliever) with ibuprofen (an NSAID). The ibuprofen part is the piece to watch. NSAIDs like ibuprofen already nudge up bleeding risk by irritating the stomach lining and making platelets a little less sticky. Melatonin may have a mild blood-thinning effect of its own, so stacking the two could, in theory, add to that bleeding tendency.

To be fair, this is mostly theoretical, with only a few scattered case reports (mostly involving warfarin, not ibuprofen). Most people won't notice anything. Still, keep an eye out for things like easy bruising, dark or tarry stools, or stomach upset. If you take Vicoprofen regularly or have any bleeding concerns, just run it by your pharmacist or doctor first.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

4 of 5

Hydrocodone, Ibuprofen also falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES.

Theoretically, melatonin might increase levels of drugs metabolized by CYP2D6.
Laboratory research suggests that certain lots of melatonin inhibit CYP2D6. Theoretically, combined administration of melatonin with certain drugs metabolized by the CYP2D6 enzyme may reduce the metabolism of these drugs, resulting in increased serum levels. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.
Severity Minor 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

Here's the thing to know about Vicoprofen, which combines hydrocodone with ibuprofen. The hydrocodone part is actually a prodrug, meaning your body uses an enzyme called CYP2D6 to convert it into hydromorphone, the form that does most of the pain-relieving work. Lab studies hint that some batches of melatonin might slow down that same enzyme.

If that happened, it could theoretically blunt the conversion, leaving you with less pain relief rather than more. But please don't lose sleep over this one. The evidence is only from test-tube and animal research, the severity is rated minor, and real-world reports are lacking. If you take both regularly and notice your pain isn't well controlled, just mention it to your pharmacist or doctor.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

5 of 5

Hydrocodone, Ibuprofen also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, melatonin might increase levels of drugs metabolized by CYP3A4.
Laboratory research shows that certain lots of melatonin inhibit CYP3A4. Theoretically, combined administration of melatonin with certain drugs metabolized by CYP3A4 may reduce the metabolism of these drugs, resulting in increased serum levels. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.
Severity Minor 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

Here's the situation with Vicoprofen, which pairs hydrocodone with ibuprofen. The hydrocodone part gets processed in part by a liver enzyme called CYP3A4. In a test-tube setting, some batches of melatonin have slowed that enzyme down a bit. In theory, that could let a little more hydrocodone build up than usual, which might nudge up its effects like extra drowsiness, dizziness, or feeling foggy.

I want to be honest with you though: this is only lab-based, weak evidence, and it's rated a minor interaction. For most people taking occasional melatonin for sleep, it's unlikely to cause real trouble. Since both can make you sleepy, just be cautious and check with your pharmacist or doctor before combining them regularly.

About Melatonin

What is Melatonin?

Melatonin
  • Trouble falling asleep (insomnia)
  • Jet lag
  • Delayed sleep phase syndrome
  • Non-24-hour sleep-wake disorder
  • Shift-work sleep problems
  • Sleep problems in some children with conditions like autism or ADHD

Melatonin is a hormone your body makes naturally to help control your sleep-wake cycle, and the supplement form is widely used to help with sleep timing problems and jet lag. The evidence is strongest for certain circadian (body-clock) disorders and is more mixed for everyday insomnia. It is generally well tolerated for short-term use, but talk with your pharmacist or doctor before starting, especially for children or during pregnancy.
