Antibiotic with mucolytic (mucus thinner)
Last reviewed June 2026
Who is this for?
This is a combination drug that contains an antibiotic (Sulfamethoxazole and Trimethoprim, commonly called Co-trimoxazole or Septrin) to fight bacterial infections, plus Bromhexine which helps loosen thick mucus in your chest so you can cough it out more easily.
Inhibits bacterial dihydrofolate reductase (trimethoprim) and dihydropteroate synthase (sulfamethoxazole), disrupting folate synthesis and DNA replication in susceptible organisms, while bromhexine increases mucus fluidity by stimulating serous cell secretions and enhancing mucociliary clearance in respiratory airways.

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.
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.
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.
Avoid taking with blood thinners like warfarin as it increases bleeding risk. Do not combine with methotrexate (used for some cancers and joint problems) as it can cause serious side effects. Avoid alcohol as it increases the chance of stomach upset and dizziness.
