PROMETHAZINE

Overview

Promethazine is a versatile medicine used to help with a variety of conditions like allergies, nausea, vomiting, and motion sickness. It’s also sometimes used as a sedative (to make you sleepy) before surgery or during anxiety.
Classification
Antihistamines
Uses
Promethazine is commonly used to:
Relieve allergy symptoms like sneezing, itching, watery eyes, and runny nose

Prevent and treat nausea or vomiting (e.g., from travel sickness or surgery)

Make you drowsy before operations or when calming is needed

Help with motion sickness

Sometimes used to treat mild anxiety or help with sleep

How It Works:
Promethazine works by blocking histamine, a natural chemical the body makes during an allergic reaction. It also affects other parts of the brain to reduce nausea and make you feel relaxed or sleepy, depending on the dose.

Dosage:
As prescribed by your doctor.

Side effects
Drowsiness or feeling sleepy

Dizziness or lightheadedness

Dry mouth or blurred vision

Constipation or trouble urinating

Rarely, it can cause confusion or restlessness, especially in older adults or young children

Precautions
Avoid driving or operating machines until you know how it affects you—it can cause sleepiness or slow thinking

Let your doctor know if you have conditions like asthma, lung disease, liver problems, epilepsy, or glaucoma

Avoid alcohol, as it may intensify drowsiness or dizziness

Use cautiously in young children and older adults, who may be more sensitive to its effects

If you’re pregnant or breastfeeding, talk to your healthcare provider before using it

Don’t take it with other medications that make you sleepy unless your doctor approves
