Myrox SR 75 mg Capsule

Myrox SR is a 75 mg sustained-release capsule of ambroxol, made by Advanced Chemical Industries Limited. It is used as a mucolytic expectorant to help loosen thick mucus in respiratory tract conditions with productive cough.

Myrox SR 75 mg capsule is a mucolytic medicine from Advanced Chemical Industries Limited containing Ambroxol. It is used for productive (wet) cough with thick, sticky phlegm in conditions such as bronchitis, asthma-related mucus, COPD, and chest infections. By loosening the mucus, Myrox SR makes coughing more effective so the chest clears faster — a common need during Bangladesh's dusty winters and frequent respiratory infections.

Ambroxol works by breaking the structure of thick mucus and stimulating the airway lining to produce thinner, more watery secretions. It also boosts natural surfactant and activates the tiny hairs (cilia) that sweep mucus out of the lungs. The result is phlegm that is easier to cough up, less chest congestion, and relief of the heavy, rattling feeling in the chest.

• Productive (wet) cough with thick, sticky phlegm
• Acute and chronic bronchitis
• COPD and bronchial asthma with difficult mucus
• Tracheobronchitis and chest congestion in respiratory infections
• Sore throat relief (lozenge/specific formulations)

Ambroxol is usually well tolerated. The most common side effects are mild stomach discomfort, nausea, altered taste, dry mouth or throat, and occasionally diarrhoea or heartburn. Rash and itching are uncommon. Very rarely, ambroxol can trigger severe skin reactions (blistering, peeling, mouth sores with fever) — stop immediately and seek medical care if any rash with blisters appears. Allergic reactions with facial swelling or breathing difficulty also need urgent attention.

Use with caution in stomach or duodenal ulcer disease, as ambroxol may irritate the stomach lining, and in significant kidney or liver impairment where doses may need adjusting. A productive cough is protective — avoid combining ambroxol with cough suppressants (like dextromethorphan), since blocking the cough while loosening mucus can cause secretions to pool in the chest. Supportive care matters: warm fluids, steam inhalation, and avoiding smoke and dust all speed recovery. Seek medical advice for cough lasting beyond 2–3 weeks.

Ambroxol has few significant drug interactions. Taken with antibiotics such as amoxicillin, cefuroxime, erythromycin, or doxycycline, it increases their concentration in lung tissue — often a helpful effect used intentionally in chest infections. The main combination to avoid is with antitussive (cough-suppressant) medicines, which can dangerously trap loosened mucus in the airways. Tell your doctor or pharmacist about all medicines you take, including cough-cold combination syrups that may already contain similar ingredients.

Ambroxol must not be used by people with known hypersensitivity to ambroxol or bromhexine. It is generally avoided in the first trimester of pregnancy. Patients with a previous severe skin reaction linked to ambroxol should never take it again. Some syrup formulations contain sugar or sweeteners that need caution in specific metabolic disorders — check with your pharmacist.

Pregnancy: Avoid ambroxol in the first trimester. In the second and third trimesters it may be used if a doctor considers it necessary, as available data have not shown harm. Lactation: Small amounts pass into breast milk and are unlikely to harm the baby, but use during breastfeeding only on a doctor's advice. Simple measures — warm fluids and steam — are often tried first in pregnancy.

Store as printed on the pack and keep out of the reach of children.
