Bromhexine Dosage Guide: What You Need to Know

If you’ve been prescribed bromhexine for a cough or chest congestion, the first question is usually "how much should I take?" This guide breaks down the typical doses, when to adjust them, and how to use the medicine safely.

Standard adult dosage

For most adults, the usual dose is 8 mg three times a day. That means you take a tablet or syrup every 8 hours, preferably after meals. If you’re using the liquid form, 5 ml (which contains about 8 mg) is the typical amount. Stick to the schedule – missing a dose can let the mucus build up again.

Dosage for children

Kids get a lower dose based on their weight. The rule of thumb is 0.5 mg per kilogram of body weight, given three times daily. For example, a child weighing 20 kg would take about 10 mg total each day, split into three doses of roughly 3–4 mg. Always use the measuring spoon or syringe that comes with the liquid to avoid guessing.

Remember, children under 2 years old usually aren’t given bromhexine unless a doctor says it’s safe. If you’re unsure, ask your pharmacist for a quick check.

Special situations

If you have liver or kidney problems, your doctor might lower the dose or spread it out more. People with severe asthma should also check with their doctor before adding bromhexine, because it only helps thin mucus, not open airways.

Pregnant or breastfeeding moms should talk to a healthcare professional. While bromhexine is generally considered low‑risk, it’s best to get a clear recommendation for your situation.

How to take bromhexine correctly

Take bromhexine with a full glass of water. The medicine works best when your stomach isn’t empty, so having a light snack can help. Don’t crush tablets unless the label says you can; crushing can change how the drug is absorbed.

If you miss a dose, take it as soon as you remember – but only if it’s more than a few hours before the next scheduled dose. Skip the missed one if it’s almost time for the next dose; doubling up can cause stomach upset.

Side effects and safety tips

Most people tolerate bromhexine well. Common side effects are mild stomach upset or a slight bitter taste. Rarely, you might feel a rash or dizziness. If any of these get worse, stop the medicine and call your doctor.

Keep the medication out of reach of kids, even if it’s a syrup. Store it in a cool, dry place and check the expiration date before each use.

That’s the quick rundown on bromhexine dosage. Follow the recommended amounts, watch for any unusual reactions, and you’ll help your lungs clear mucus faster. Got more questions? Ask your pharmacist – they’re the best source for personal advice.
