diphenhydramine and Drug Overdose

diphenhydramine has been researched along with Drug Overdose in 74 studies

Diphenhydramine: A histamine H1 antagonist used as an antiemetic, antitussive, for dermatoses and pruritus, for hypersensitivity reactions, as a hypnotic, an antiparkinson, and as an ingredient in common cold preparations. It has some undesired antimuscarinic and sedative effects.
diphenhydramine : An ether that is the benzhydryl ether of 2-(dimethylamino)ethanol. It is a H1-receptor antagonist used as a antipruritic and antitussive drug.
antitussive : An agent that suppresses cough. Antitussives have a central or a peripheral action on the cough reflex, or a combination of both. Compare with expectorants, which are considered to increase the volume of secretions in the respiratory tract, so facilitating their removal by ciliary action and coughing, and mucolytics, which decrease the viscosity of mucus, facilitating its removal by ciliary action and expectoration.

Drug Overdose: Accidental or deliberate use of a medication or street drug in excess of normal dosage.

Dosage of Fentanyl

Moderate sedation (using the American Society of Anesthesiologists definition of maintaining purposeful response to verbal or tactile stimulation, adequate ventilation requiring no airway protection, and maintenance of cardiovascular function) was then achieved using incremental doses of the combination of intravenous midazolam (1 mg) and fentanyl (25 μg) given every 2 to 3 minutes.
