How it works

How to take this drug

For the suspension form (like Bronquidiazina C.R.), adults typically take the dose recommended on the pack or by your doctor, usually twice a day (morning and evening) for 5 to 7 days. Take it with or after food to reduce stomach upset. Shake the bottle well before each use.

What if I Miss a Dose?

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take a double dose to make up for it.

Important for antibiotics

Always complete the full course even if you feel better. Stopping early can cause the infection to return and become drug-resistant.

What to watch out for

Always complete the full course of this antibiotic even if you feel better — stopping early can make the infection come back stronger. Buy only from a registered pharmacy, not from roadside sellers or open markets where storage conditions are poor. Do not share this medication with others, even if they have similar symptoms.
