Description
Promethazine 10 mg
Promethazine 10 mg is a prescription-strength antihistamine used to treat allergy symptoms, nausea, vomiting, motion sickness, and short-term sleep issues. As a lower dose option, it is especially useful for patients who need mild symptom control or are sensitive to sedatives. It works by blocking histamine and affecting signals in the brain that control nausea and alertness.
What is Promethazine 10 mg?
Promethazine 10 mg is a lower-dose formulation of this widely used antihistamine and antiemetic medication. It is prescribed for allergy relief, nausea control, motion sickness prevention, and sometimes as a mild sleep aid. Its sedative effects are milder at this dose, making it suitable for those who need gentle symptom relief.
Drug Classification
Promethazine belongs to the phenothiazine group and is considered a first-generation H1-receptor antagonist. In addition to antihistaminic properties, it acts on the brain’s emetic center, giving it powerful anti-nausea effects.
How Promethazine Works
Promethazine works by blocking the effects of histamine, a natural substance the body releases during allergic reactions. It also affects certain brain signals that trigger nausea and vomiting. At lower doses, like 10 mg, it can provide therapeutic benefits with reduced sedation, making it ideal for daytime use or for sensitive patients.
