Diphenhydramine is an antihistamine that is commonly used to manage sleep disturbances.

- Short‑term insomnia: facilitates sleep onset in adults with occasional difficulty falling asleep. - Sleep onset difficulty: reduces the time required to fall asleep. - Transient sleep disturbance due to environmental factors: provides temporary sedation for brief periods of disrupted sleep.

Diphenhydramine may cause a range of adverse reactions, most of which are dose‑related and reversible.

Common Side Effects: - Drowsiness: persistent sleepiness during waking hours. - Dry mouth: reduced salivary flow causing discomfort. - Blurred vision: temporary visual disturbances. - Constipation: slowed gastrointestinal motility. - Dizziness: light‑headed sensation, especially when standing. - Urinary retention: difficulty initiating urination.

Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis): rash, swelling, difficulty breathing. - Cardiac arrhythmia: irregular heart rhythm, potentially life‑threatening. - Confusion or hallucinations: altered mental status, more common in the elderly. - Seizures: rare but possible in susceptible individuals. - Tachycardia: rapid heart rate that may require medical attention.

When using Oberon Sleep Aid, consider the following safety measures.

- Avoid driving or operating machinery: sedation may impair alertness. - Do not combine with alcohol or other CNS depressants: increased risk of excessive drowsiness. - Use with caution in elderly patients: higher incidence of anticholinergic side effects. - Avoid in patients with narrow‑angle glaucoma: anticholinergic activity can precipitate an attack. - Pregnancy and breastfeeding: consult a healthcare professional; safety has not been established. - Store at room temperature: keep in the original pack, protect from moisture and heat.

Diphenhydramine can interact with several medicines; monitoring is advised.

Major Interactions (Avoid): - Alcohol: additive central nervous system depression. - Other antihistamines or sedatives: risk of profound sedation. - Tricyclic antidepressants: increased anticholinergic burden.

Moderate Interactions (Monitor Closely): - Benzodiazepines or opioids: enhanced sedative effect, monitor respiratory status. - Anticholinergic drugs (e.g., atropine): cumulative anticholinergic effects. - Selective serotonin reuptake inhibitors (SSRIs): may increase overall sedation.
