Target name:
Daytime Wakefulness
Severity:
major
Interaction type:
adverse
Nature:
temporal
Temporal spacing:
Hours before target:
8
Hours after target:
null
Description:
Taking melatonin during the day or too close to your wake-up time can cause significant circadian rhythm disruption, leading to daytime drowsiness, impaired performance, and sleep-wake cycle confusion.
Actionable advice:
Never take melatonin during the day or within 8 hours of when you plan to wake up.
Target id:
/dietary/alcohol-acute
Target name:
Alcohol
Severity:
major
Interaction type:
adverse
Nature:
temporal
Temporal spacing:
Hours before target:
4
Hours after target:
8
Description:
Alcohol is a central nervous system depressant that has an additive effect with melatonin, potentially causing excessive drowsiness, dizziness, and impaired coordination. It also disrupts sleep architecture in the second half of the night.
Actionable advice:
Avoid consuming alcohol for at least 4 hours before taking melatonin.
Target id:
/class/cns-depressants
Target name:
Sedatives and CNS Depressants
Severity:
major
Interaction type:
adverse
Nature:
absolute
Description:
Combining melatonin with other sedating substances (e.g., benzodiazepines, Z-drugs like zolpidem, opioids, certain antihistamines) can lead to excessive sedation, impaired motor function, and potentially dangerous respiratory depression.
Actionable advice:
Do not combine with other sedating medications unless explicitly approved by your physician.
Target id:
/class/cyp1a2-inhibitors
Target name:
CYP1A2 Inhibitors (e.g., Fluvoxamine, Ciprofloxacin)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Description:
These drugs strongly inhibit the primary enzyme (CYP1A2) responsible for metabolizing melatonin. This can cause melatonin levels in the blood to increase dramatically, elevating the risk of side effects like next-day drowsiness.
Actionable advice:
Avoid this combination; consult your doctor for alternatives as dose adjustments are critical.
Target id:
/condition/pregnancy
Target name:
Pregnancy
Severity:
major
Interaction type:
adverse
Nature:
absolute
Description:
Melatonin is a hormone that crosses the placenta and plays a role in fetal development. The effects of exogenous supplementation on the fetus are not well-established, and it is therefore contraindicated.
Actionable advice:
Avoid completely during pregnancy.
Target id:
/condition/lactation
Target name:
Breastfeeding (Lactation)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Description:
Melatonin is known to pass into breast milk. The effects of supplemental melatonin on a nursing infant's developing circadian system are unknown and potentially harmful.
Actionable advice:
Avoid completely while breastfeeding.
Target id:
/intervention/blue-light-exposure
Target name:
Blue Light Exposure (Screens, Bright Lights)
Severity:
moderate
Interaction type:
diminishing
Nature:
temporal
Temporal spacing:
Hours before target:
0
Hours after target:
2
Description:
Exposure to blue-spectrum light, particularly from electronic screens and bright indoor lighting, sends a strong wakefulness signal to the brain that directly suppresses and counteracts the sleep-promoting effects of both endogenous and supplemental melatonin.
Actionable advice:
Cease use of all screens and dim household lights at least 1-2 hours before bed.
Target id:
/class/cyp1a2-inducers
Target name:
CYP1A2 Inducers (e.g., Smoking, Carbamazepine)
Severity:
moderate
Interaction type:
diminishing
Nature:
absolute
Description:
These substances, particularly compounds in tobacco smoke, accelerate the activity of the CYP1A2 enzyme, causing melatonin to be broken down and cleared from the body much faster, thereby reducing its effectiveness.
Actionable advice:
Be aware that smoking or taking these specific drugs may render melatonin supplements ineffective.
Target id:
/class/anticoagulants-antiplatelets
Target name:
Anticoagulants and Antiplatelets (e.g., Warfarin, Aspirin)
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
Melatonin may inhibit platelet aggregation. When combined with medications that thin the blood or prevent clotting, there is a theoretical increased risk of bruising and bleeding.
Actionable advice:
Use with caution and consult your doctor before combining with blood-thinning medications.
Target id:
/class/antidiabetic-medications
Target name:
Diabetes Medications
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
Melatonin can influence glucose metabolism and insulin sensitivity, particularly when taken at night. This may alter blood sugar levels and interfere with the intended action of medications for diabetes.
Actionable advice:
Monitor blood glucose levels closely if you have diabetes, especially when starting or stopping melatonin.
Target id:
/condition/autoimmune-disease
Target name:
Autoimmune Conditions (e.g., Rheumatoid Arthritis, Lupus)
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
Melatonin has immune-modulating effects, including the potential to stimulate certain immune cells (like T-helper cells). This could theoretically exacerbate conditions where the immune system is already overactive.
Actionable advice:
Consult your specialist before using melatonin if you have a diagnosed autoimmune condition.
Target id:
/condition/seizure-disorder
Target name:
Seizure Disorder / Epilepsy
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
There are conflicting reports, but some evidence suggests melatonin may alter brain electrical activity and potentially lower the seizure threshold in individuals with epilepsy.
Actionable advice:
Do not use melatonin if you have a seizure disorder without consulting your neurologist.
Target id:
/intervention/caffeine
Target name:
Caffeine
Severity:
moderate
Interaction type:
diminishing
Nature:
temporal
Temporal spacing:
Hours before target:
8
Hours after target:
null
Description:
Caffeine is a potent adenosine receptor antagonist, a mechanism that promotes wakefulness and directly opposes the sleep-promoting actions of melatonin. Its long half-life means afternoon consumption can still interfere with nighttime sleep.
Actionable advice:
Avoid all sources of caffeine for at least 8 hours before taking melatonin.
Target id:
/class/immunosuppressants
Target name:
Immunosuppressant Medications
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
The immune-stimulating properties of melatonin may counteract the intended effects of medications designed to suppress the immune system, such as those used after organ transplantation (e.g., cyclosporine, tacrolimus).
Actionable advice:
Avoid melatonin if you are taking immunosuppressive therapy.
Target id:
/class/beta-blockers
Target name:
Beta-Blocker Medications
Severity:
minor
Interaction type:
diminishing
Nature:
absolute
Description:
Certain beta-blockers (e.g., propranolol, atenolol) are known to suppress the body's natural nighttime synthesis and release of melatonin from the pineal gland, which can contribute to sleep disturbances.
Actionable advice:
Be aware this medication may be the cause of sleep issues; discuss melatonin supplementation with your doctor.
Target id:
/class/calcium-channel-blockers
Target name:
Calcium Channel Blockers
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Description:
Both melatonin and certain calcium channel blockers (e.g., nifedipine) can lower blood pressure. Their combined use may have a small additive hypotensive effect.
Actionable advice:
Use with caution and monitor blood pressure if you are taking these medications.
Target id:
/class/nsaids
Target name:
Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
Severity:
minor
Interaction type:
diminishing
Nature:
absolute
Description:
NSAIDs inhibit prostaglandin synthesis. Since prostaglandins are involved in the body's natural production of melatonin, chronic or evening use of NSAIDs may slightly reduce endogenous melatonin levels.
Actionable advice:
Be aware that regular evening use of NSAIDs might slightly blunt natural melatonin production.
Target id:
/class/estrogens
Target name:
Estrogens and Progestins (Hormonal Therapy & Contraceptives)
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Description:
Oral contraceptives and hormonal therapies containing estrogen may alter the metabolism of melatonin, potentially leading to higher-than-expected levels.
Actionable advice:
Be aware that hormonal medications may increase melatonin levels; a lower dose may be needed.
Target id:
/class/cns-depressants
Target name:
Sedating Herbal Supplements (e.g., Valerian, Kava, Chamomile)
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Description:
Combining melatonin with other supplements known to cause drowsiness can result in an additive sedative effect, potentially leading to excessive sleepiness or grogginess.
Actionable advice:
Use caution when combining with other sleep-promoting supplements and start with a low dose.
