These two interact in 7 distinct ways. Each one is explained separately below.
Why Are There 7 Interactions?
Melatonin interacts with whole categories of medication. Aspirin, Caffeine, Hydrocodone falls into 7 of those categories, so it can interact with Melatonin in 7 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).
CNS DEPRESSANTS
1 of 7Why this applies to Aspirin, Caffeine, Hydrocodone
Aspirin, Caffeine, Hydrocodone falls under CNS DEPRESSANTS — the group Melatonin interacts with.
Melatonin has sedative effects. Theoretically, concomitant use of melatonin with alcohol, benzodiazepines, or other sedative drugs might cause additive sedation.
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.
The piece of this combo pill that matters most here is the hydrocodone, an opioid painkiller that already makes many people feel drowsy, foggy, or relaxed. Melatonin nudges your body toward sleep too, so layering the two together could add up. The concern is mainly extra sleepiness, slowed thinking, or feeling more groggy than usual, especially when you first start.
To be fair, this caution is theoretical, based on how both products work rather than strong studies, so it is not a guaranteed problem. The caffeine in this pill may even blunt some drowsiness. Still, hydrocodone deserves respect. Be careful with driving until you know how you feel, and check with your pharmacist or doctor before combining them.

SEIZURE THRESHOLD LOWERING DRUGS
2 of 7Aspirin, Caffeine, Hydrocodone also falls under SEIZURE THRESHOLD LOWERING DRUGS.
Some clinical evidence suggests that melatonin may increase the frequency of seizures in certain patients, particularly children with neurological disabilities.
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.
Here's what's going on with your Damason-P combo (aspirin, caffeine, and the opioid hydrocodone) alongside melatonin. The piece that matters here is that certain medicines can slightly lower the seizure threshold, meaning they can make the brain a bit more prone to a seizure. Opioids like hydrocodone can do this, especially at higher doses, and the caffeine in this product is a mild stimulant too. The concern is that melatonin might add to that and make a seizure a little more likely.
I want to be honest: this is a theoretical caution based mostly on how these drugs behave, with some real-world reports in children who have neurological conditions. For most adults using this short-term, it's unlikely to cause a problem. Still, if you have a seizure history, check with your pharmacist or doctor before combining them.
CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES
3 of 7Aspirin, Caffeine, Hydrocodone also falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES.
Melatonin is metabolized in the liver primarily by the CYP2C19 and CYP1A2 enzymes. Theoretically, combined administration of melatonin with drugs metabolized by the CYP1A2 enzyme might reduce the metabolism of these drugs, resulting in increased serum levels. Conversely, some drugs metabolized by CYP1A2 may inhibit the metabolism of melatonin, resulting in increased serum levels of melatonin. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.
Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..
In this combination product, the piece that actually connects to melatonin is the caffeine. Caffeine is cleared by a liver enzyme called CYP1A2, and the same enzyme helps break down melatonin. On paper, the two may slow each other down a bit, so caffeine could hang around a little longer (think jitteriness, a racing heart, or trouble settling to sleep, which is the opposite of what you want from melatonin), and melatonin levels could nudge upward too.
The good news: this is a theoretical concern based on how the enzyme works, not strong real-world proof, and the caffeine dose in these tablets is modest. The hydrocodone and aspirin parts are not really involved here. Still, since melatonin is taken for sleep, run it by your pharmacist or doctor before pairing them.

ANTICOAGULANT/ANTIPLATELET DRUGS
4 of 7Aspirin, Caffeine, Hydrocodone also falls under ANTICOAGULANT/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.
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.
This combination product (Damason-P) contains aspirin, which thins the blood a bit by making your platelets less sticky. Melatonin has its own mild blood-thinning signal in some early research, so pairing the two could, in theory, nudge your bleeding risk a little higher. With aspirin, that might show up as easier bruising, nosebleeds, or stomach upset, and rarely something more serious like blood in the stool.
Honestly, this concern rests on a few case reports and small studies, so it is more theoretical than proven. For most people taking occasional doses it is unlikely to cause trouble. Still, if you take aspirin daily, are on a higher dose, or have any history of bleeding or ulcers, check with your pharmacist or doctor before adding melatonin.

CAFFEINE
5 of 7Aspirin, Caffeine, Hydrocodone also falls under CAFFEINE.
Some evidence suggests that caffeine consumption can decrease endogenous melatonin levels, while other evidence suggests that caffeine increases endogenous melatonin levels. When administered in combination with melatonin supplements, caffeine seems to increase melatonin effects and levels. The reason for this discrepancy is not completely clear. Part of the discrepancy may result from the fact that caffeine can inhibit melatonin synthesis as well as inhibit melatonin metabolism. By functioning as an adenosine receptor antagonist, caffeine may indirectly inhibit the synthesis of melatonin. Conversely, because melatonin and caffeine are both metabolized by cytochrome P450 1A2 (CYP1A2) enzyme, concomitant use of melatonin and caffeine may reduce the metabolism of melatonin, resulting in higher serum levels.
Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..
Here's the wrinkle with this combo: the medication you're asking about (Damason-P) is a mix that includes caffeine. The interaction on file is really between that caffeine and your melatonin. Both are cleared by the same liver enzyme (CYP1A2), so when they're taken together, the caffeine can slow how fast your body breaks down melatonin. The practical result is that your melatonin levels may run a bit higher, so you could feel extra drowsy or groggy.
This evidence is on the softer side and the effect is usually mild, but melatonin already nudges you toward sleep, and hydrocodone is sedating too. Stacking sleepiness on top of a narcotic is worth a quick chat with your pharmacist before combining them.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES
6 of 7Aspirin, Caffeine, Hydrocodone also falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES.
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.
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.
This combo product (brand name Damason-P) mixes aspirin, caffeine, and hydrocodone for pain relief. The piece that matters here is the hydrocodone. It's a bit unusual: hydrocodone is partly turned into a stronger painkiller (hydromorphone) by a liver enzyme called CYP2D6. Some lab studies hint that certain batches of melatonin might slow that same enzyme down.
If that happened, you could in theory see a touch more drowsiness, dizziness, nausea, or constipation, especially since melatonin already makes you sleepy. But honestly, this is rated minor and rests only on test-tube data, so it may not show up in real life at all. Still, if you feel extra groggy taking them together, mention it to your pharmacist or doctor.
- Foster BC, Cvijovic K, Boon HS, et al. Melatonin Interaction Resulting in Severe Sedation. J Pharm Pharm Sci 2015;18(2):124-31. PubMed
CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES
7 of 7Aspirin, Caffeine, Hydrocodone also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.
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.
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.
Here's the gist with this combo product, which pairs aspirin and caffeine with hydrocodone (an opioid pain reliever). The concern on file is purely theoretical: in lab dishes, some batches of melatonin appeared to slow down the CYP3A4 enzyme, one of the pathways that helps process hydrocodone. If that happened in real life, hydrocodone could build up a bit and feel stronger, which might mean more drowsiness, dizziness, slowed breathing, or constipation.
But take a breath. This is rated minor and comes only from test-tube and animal data, not from people. For most healthy adults, occasional melatonin for sleep isn't likely to cause a problem here. Since hydrocodone is a controlled opioid, it's still smart to mention your melatonin use to your pharmacist or doctor, especially if you notice extra grogginess.
