Chlorpromazine: Uses, Dosage & What to Expect
If you’ve been prescribed chlorpromazine, you probably wonder why this old‑school drug is still around. It’s a classic antipsychotic that helps calm severe mental health symptoms and even works for stubborn nausea. Below we break down the basics so you can use it with confidence.
When and How to Take Chlorpromazine
Doctors usually start you on a low dose, often 25‑50 mg at bedtime, then adjust based on response. Swallow the tablet whole with water; crushing it can change how your body absorbs the medicine. If you’re taking it for nausea, a doctor may suggest a higher dose before meals.
Timing matters. Taking it early in the evening helps avoid daytime drowsiness, which is one of its most common effects. If you miss a dose, take it as soon as you remember—unless it’s close to your next scheduled dose, then just skip the missed one and continue as normal.
Common Side Effects & When to Call a Doctor
Most people feel sleepy, dizzy, or notice a dry mouth. These usually calm down after a week or two. Keep an eye on any sudden heart palpitations, severe low blood pressure, or unexplained fever—those require medical attention right away.
Weight gain and blurry vision can happen with longer use. If you notice changes in mood, such as worsening depression or new anxiety, talk to your doctor. They may tweak the dose or switch you to a different medication.
Because chlorpromazine can affect blood sugar, people with diabetes should check their glucose levels more often. Also, avoid alcohol; mixing the two makes drowsiness far worse and can be dangerous.
Some medicines interact badly with chlorpromazine—especially other antipsychotics, certain antibiotics, and heart drugs like quinidine. Always give your pharmacist a complete list of what you’re taking to prevent surprises.
If you’re pregnant or planning a baby, discuss risks with your doctor. Chlorpromazine crosses the placenta and may affect the newborn, so a careful risk‑benefit analysis is needed.
Storing the pills is simple: keep them at room temperature, away from moisture and direct sunlight. Keep them out of reach of children—this drug can be harmful if taken by accident.
Overall, chlorpromazine works well when used correctly and monitored closely. Stick to your prescribed schedule, report any odd symptoms, and stay in touch with your healthcare team. That way you get the calm and relief you need without unnecessary hassle.
