The Duolin inhaler is commonly used to treat chronic obstructive pulmonary disease (COPD) and asthma. It contains two active ingredients: ipratropium bromide and salbutamol. Ipratropium is an anticholinergic agent that helps open up the airways, while salbutamol is a bronchodilator that relaxes the muscles in the lungs, making it easier to breathe. This combination helps manage symptoms like wheezing, shortness of breath, and tightness in the chest. The inhaler is typically used as a reliever or maintenance treatment, providing quick relief from acute respiratory issues and improving lung function over time.

The Duolin inhaler can cause some side effects, though not everyone experiences them. Common side effects include:

Dry mouth or a bad taste in the mouth.

Headache or dizziness.

Coughing or throat irritation.

Shakiness or tremors.

Increased heart rate (palpitations).

Nausea or an upset stomach.

In rare cases, more serious side effects can occur, such as:

Severe allergic reactions (rash, swelling, difficulty breathing).

Worsening of breathing problems.

Chest pain or irregular heartbeat.

If any of these severe symptoms occur, it's important to seek medical attention immediately.
