Ambroxol - oral

Patient Medicine Information
Why do I need this medicine?
Ambroxol is used for lung conditions associated with abnormal, thick, and viscous mucus secretions (phlegm).

This medicine works by making the phlegm less sticky and thick so that it can be coughed up more easily.

Ambroxol may also be used for the relief of sore throat.
How do I take this medicine?
Take Ambroxol exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.

Take it together with food or immediately after a meal. Try to take it at the same time each day.

This medicine is available as a conventional tablet, sustained-release or retard capsule, lozenge, and as an oral syrup or drops.

If you are taking the oral syrup or drops, shake the bottle well before you take it to ensure that the liquid is evenly mixed. Use the measuring spoon, cup or dropper provided to measure your prescribed dose. The oral drops may be mixed with water, milk, or juice. Once it is mixed, drink it immediately.

If you are taking the sustained-release or retard type of capsule (usually labelled as "SR" or "Retard"), swallow it whole with a glass of water. Do not divide, chew or crush the capsule.

If you are taking the lozenge, suck the lozenge until the taste become strong, then lodge the lozenge between the gums and cheek. When the taste fades, start sucking it again. Repeat until the lozenge completely dissolves. Do not swallow.
What should I do if I have forgotten to take this medicine?
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.

DO NOT double a dose under any circumstances.
