FAQs

Theo LA contains theophylline, a methylxanthine class bronchodilator. It works by relaxing the smooth muscle of the bronchi and pulmonary blood vessels and by reducing airway responsiveness. Unlike short-acting theophylline, the long-acting version allows for less frequent dosing and more stable blood levels. It is used as a maintenance therapy and is not a rescue inhaler for sudden breathing attacks.

How can I buy Theo LA online? +
You can buy Theo LA online with a valid prescription from your doctor. Ensure you use a licensed pharmacy that verifies prescriptions and ensures safe shipping and storage.
What is Theo LA used for? +
Theo LA is used for maintenance treatment of asthma and COPD to help ease breathing, reduce wheezing and support lung-function long term.
How does Theo LA work? +
It relaxes the airway muscles (bronchi), improves airflow and reduces symptoms by using the active drug theophylline in a long-acting form.
How often should I take Theo LA? +
Your doctor will advise — many people take it once or twice daily. It's important to take it at the same times each day for consistent effect.
What should I do if I miss a dose? +
Take it as soon as you remember unless the next dose is due soon. Then skip the missed dose and continue your regular schedule. Do not double up.
Will my symptoms improve quickly? +
Some improvement may be seen within days, but maintaining good control of asthma or COPD often takes persistence and proper monitoring.
What food or drink should I avoid? +
Limit caffeine (coffee, tea, chocolate) and avoid smoking or exposure to other substances that reduce drug levels. Always follow your doctor’s advice.
Is it safe during pregnancy or breastfeeding? +
This should be discussed with your doctor. They will decide based on your condition and the benefits vs risks.
Can I use Theo LA during an asthma attack? +
No. Theo LA is for maintenance therapy. You should always have a rescue inhaler (such as a short-acting bronchodilator) for acute attacks.
What should I monitor while on Theo LA? +
Your doctor may check your theophylline blood levels, liver and kidney function, heart rate, and watch for signs of toxicity or interaction with other medications
