Naproxen diphenhydramine is a combination product that blends naproxen (an NSAID pain reliever) with diphenhydramine (an antihistamine with sedative effects) for nighttime pain relief and help with sleep. It’s sold under names like Aleve PM in the United States.
Key points to know:
- What it’s for: Short-term relief of minor aches and pains at night plus help with sleep. Not for long-term use or for chronic pain.
- Typical adult dose: One caplet at bedtime as needed. Do not exceed 2 caplets in 24 hours. Do not use in children under 12 unless directed by a doctor.
- How to take: Take with a full glass of water. Taking naproxen with food can help reduce stomach upset. Diphenhydramine can cause drowsiness, so plan to sleep afterward and avoid driving or operating heavy machinery.
- Who should be cautious:
- People with allergies to naproxen, aspirin, other NSAIDs, or diphenhydramine.
- Those with active or history of ulcers/bleeding, kidney or liver problems, high blood pressure, heart disease, or kidney disease.
- Older adults (greater risk of confusion, urinary retention, dizziness, or falls from the diphenhydramine component).
- People with glaucoma, enlarged prostate (BPH), or breathing problems (like asthma) should use with caution due to anticholinergic effects of diphenhydramine.
- Pregnant or breastfeeding people: naproxen is generally avoided in late pregnancy; diphenhydramine passes into breast milk. Talk to a clinician before use.
- Those taking alcohol or other sedatives, or other NSAIDs/anticoagulants, should avoid or use only under medical advice due to interactions and additive effects.
- Common side effects:
- Drowsiness, dizziness, and impaired alertness from the diphenhydramine component.
- Dry mouth, blurred vision, urinary retention, or constipation (anticholinergic effects).
- Stomach upset, heartburn, or nausea (naproxen component).
- Serious signs to seek care for: Severe stomach pain or vomiting blood, black/toul-stool, chest pain, severe allergic reaction (hives, swelling, trouble breathing), confusion, fainting, seizures.
- Important interactions:
- Alcohol and other CNS depressants can increase drowsiness.
- NSAIDs (including naproxen) can increase risk of stomach bleeding when used with anticoagulants, steroids, or certain antidepressants.
- Diphenhydramine can interact with other sedatives or anticholinergic drugs and with MAO inhibitors.
- Not a substitute for medical advice: If you have persistent pain, fever lasting more than a few days, sleep issues lasting more than a few nights, or you’re unsure if this product is right for you, check with a healthcare professional.
