Indications & Clinical Uses

Diphenhydramine acts as a sedating antihistamine and is used for conditions that involve difficulty sleeping.

  • Insomnia: helps initiate and maintain sleep during short‑term treatment.
  • Occasional sleeplessness: provides temporary relief of difficulty falling asleep.
  • Sleep disturbance due to minor anxiety: reduces nighttime wakefulness and promotes rest.

How It Works

  • Diphenhydramine competitively blocks peripheral H1 histamine receptors, preventing histamine‑mediated neuronal activation. This antagonism produces central sedative effects and anticholinergic activity, leading to drowsiness that facilitates sleep onset and maintenance.

Side Effects

Diphenhydramine may cause a range of adverse reactions, most of which are related to its antihistaminic and anticholinergic properties.

Common Side Effects

  • Drowsiness or excessive sleepiness
  • Dry mouth
  • Blurred vision

Serious or Rare Side Effects

  • Cardiac arrhythmia
  • Severe allergic reaction (anaphylaxis)
  • Hallucinations or delirium
  • Seizures

  • Avoid alcohol: may enhance sedative effects.

Frequently Asked Questions

Morrisons Sleep Aid contains diphenhydramine, a sedating antihistamine that is used for short‑term treatment of insomnia and occasional sleeplessness in adults. It helps people fall asleep faster and stay asleep through the night.

Diphenhydramine blocks H1 histamine receptors in the brain, reducing the wake‑promoting action of histamine. The resulting antihistaminic and anticholinergic effects produce drowsiness, making it easier to initiate and maintain sleep.

The appropriate dose of diphenhydramine is determined by a prescriber based on the individual’s age, health status, and specific sleep difficulty. Patients should follow the healthcare professional’s instructions and not exceed the recommended amount.

Safety data for diphenhydramine in pregnancy and lactation are limited. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss potential risks and benefits with their healthcare provider before using this product.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Morrisons Sleep Aid uses diphenhydramine, a first‑generation antihistamine, whereas many prescription sleep aids belong to the benzodiazepine or non‑benzodiazepine (Z‑drug) classes. Diphenhydramine is available OTC, has anticholinergic side effects, and is generally intended for short‑term use, while prescription agents may have different efficacy profiles and safety considerations.

Store the tablets at room temperature, preferably below 25 °C. Keep them in the original packaging, protect from moisture and direct sunlight, and keep out of reach of children.

Morrisons Sleep Aid is taken orally, usually with a glass of water. It is typically taken shortly before bedtime, following the dosage instructions provided by a healthcare professional.

Serious risks include severe anticholinergic toxicity, cardiac arrhythmias, hallucinations, seizures, and rare allergic reactions such as anaphylaxis. Patients should seek immediate medical attention if they experience any of these severe symptoms.

Individuals who are allergic to diphenhydramine or any component of the formulation, those taking MAO inhibitors, patients with severe asthma, uncontrolled glaucoma, or significant urinary retention should avoid using this product unless directed by a physician.
