Uniphyllin Continus
Theophylline belongs to a group of medicines called anti-asthmatics that work by relaxing the smooth muscle of the bronchi and lungs. Despite being a known substance for decades, the mechanism of action of theophylline is still under debate. In addition to its bronchodilator effects, theophylline also exhibits immunomodulatory and anti-inflammatory properties. Take this medication by mouth with a glass of water. Follow the directions on the medicine label. Take this medicine on an empty stomach, at least 1 hour before a meal. Do not crush or chew it. Take your doses at the same time every day. Do not take your medicine more often than directed. Do not stop taking it unless your doctor tells you to.

Uniphyllin Continus Tablets for Asthma Treatment and COPD Management
Uniphyllin Continus is an oral bronchodilator used as part of long-term asthma treatment and COPD management. It contains theophylline, a medicine that keeps the airways open and makes breathing feel less tight when taken regularly.
It is used for ongoing respiratory control rather than sudden flare-ups. Uniphyllin Continus tablets work steadily in the background to support airway opening and respiratory symptom management. If approved following an online consultation, Uniphyllin Continus tablets can be supplied through Pharmacy Planet as part of your chronic respiratory therapy plan.
What Is Uniphyllin Continus?
Uniphyllin Continus is a prolonged-release tablet containing theophylline. It is designed for long-term treatment of asthma and chronic breathing conditions such as emphysema and chronic bronchitis. As the tablets release medicine slowly over 12 hours, they provide consistent airway control when taken twice daily.
Uniphyllin Continus tablets are not a rescue medicine for sudden breathing attacks and do not replace a fast-acting reliever inhaler.
How Do Uniphyllin Continus Tablets Work?
Asthma and COPD symptoms often come from narrowed airways and ongoing inflammation. Uniphyllin Continus tablets work primarily by relaxing airway muscles. It does not replace inhaled corticosteroids, which remain the main treatment for controlling airway inflammation.
- Keeps the Airways Open — Theophylline relaxes the muscles around the airways, allowing air to move in and out more freely.
- Supports Ongoing Airway Control — As a prolonged-release tablet, Uniphyllin Continus maintains bronchodilator activity for up to 12 hours at a time.
- Supports Long-Term Symptom Control — When taken regularly, it reduces chest tightness and breathlessness linked to chronic respiratory conditions.
How to Take Uniphyllin Continus Tablets
Uniphyllin Continus tablets are taken every 12 hours, ideally at the same times each day, to maintain steady airway opening and respiratory control.
Usual Dose (Adults):
- One tablet every 12 hours.
- Usual starting dose is 200 mg twice daily, which may be increased to 300 mg or 400 mg twice daily depending on response and blood test results.
- Swallow the tablets whole with water. Do not crush, chew, or break them, as this releases the full dose too quickly and can be dangerous.
If You Miss a Dose: Skip the missed dose and take your next dose at the usual time. Do not take a double dose to make up for a missed one.
Who Can Use Uniphyllin Continus Tablets?
Uniphyllin Continus tablets may be suitable if you:
- Have asthma that needs additional long-term bronchodilator treatment.
- Have COPD and require oral bronchodilator support as part of airway management.
- Need consistent respiratory care alongside inhaled treatments.
