Hoggar Night (Doxylamine Hydrogen Succinate)

Hoggar Night is indicated for short‑term relief of occasional insomnia and for symptomatic treatment of allergic rhinitis. It may also be used to alleviate other minor allergy‑related discomforts.

• Temporary sleep difficulties (insomnia) in adults
• Relief of nasal congestion, sneezing, and watery eyes due to allergic rhinitis
• Management of mild hay‑fever symptoms
• Adjunctive use for occasional restless nights when other non‑pharmacologic measures are insufficient

• Doxylamine hydrogen succinate acts as a competitive antagonist at peripheral and central histamine H1 receptors. By blocking these receptors, it reduces the action of endogenous histamine, leading to decreased wakefulness and sedation. The anticholinergic activity also contributes to its antihistaminic effects, helping to alleviate allergic symptoms such as nasal congestion and itching.

Adverse reactions to Hoggar Night are generally dose‑related and may vary in frequency.

Common

• Drowsiness or excessive sleepiness
• Dry mouth, throat, or nasal passages
• Dizziness or light‑headedness
• Blurred vision
• Constipation or difficulty urinating

Serious

• Severe allergic reaction (rash, itching, swelling, difficulty breathing)
• Cardiac arrhythmias in susceptible individuals
• Marked confusion or hallucinations, especially in the elderly
• Persistent tachycardia or palpitations

Before using Hoggar Night, consider the following safety points:

• Avoid use if you have known hypersensitivity to doxylamine or other first‑generation antihistamines.
• Use caution when operating machinery or driving, as sedation can impair alertness.
• Discuss with a healthcare professional if you have glaucoma, enlarged prostate, or urinary retention.
• Pregnant or breastfeeding individuals should seek medical advice before use.
• Elderly patients may be more susceptible to anticholinergic side effects and should start with the lowest effective dose.
• Do not combine with alcohol or other central nervous system depressants without guidance.

Hoggar Night can interact with several medications, altering their effects.

Avoid

• Alcohol and other sedatives (e.g., benzodiazepines, opioids) due to additive CNS depression.
• Monoamine oxidase inhibitors (MAOIs) and other antihistamines, which may increase sedation and anticholinergic burden.
• Certain antidepressants (e.g., tricyclics) that have anticholinergic properties.

Use with caution

• Anticholinergic drugs (e.g., atropine, scopolamine) may exacerbate dry mouth and urinary retention.
• CNS stimulants (e.g., caffeine, decongestants) may counteract the sedative effect.
• Medications metabolized by CYP2D6, as doxylamine may affect their plasma levels.
• Over‑the‑counter cough and cold preparations containing antihistamines.
