Theophylline: What It Is and How It Helps
Theophylline is a pill or liquid that opens up the airways so breathing feels easier. Doctors often give it to people with asthma or COPD when inhalers alone aren't enough. It works by relaxing the muscles around the tiny tubes in your lungs and by reducing swelling.
Even though it’s been around for a long time, Theophylline is still useful because it can be taken at home and doesn’t need a special device. That makes it a handy backup when you can’t use a inhaler or need extra help at night.
How to Take Theophylline the Right Way
Most doctors start you on a low dose and raise it slowly. The goal is to keep the blood level in a safe range – too low won’t help, too high can cause trouble. Typical adult doses are 200‑400 mg per day, split into two or three doses. Kids get a dose based on weight, usually about 5‑7 mg per kilogram each day.
Take Theophylline with food if it upsets your stomach. Don’t skip doses; missing a dose can make the blood level drop quickly. If you forget, take it as soon as you remember unless it’s almost time for the next dose – then just skip the missed one.
Side Effects and What to Watch For
The most common issues are nausea, headache, and a fast heartbeat. Some people feel jittery or have trouble sleeping. If you notice severe vomiting, confusion, or a tremor, call your doctor right away – those can mean the level is too high.
Because Theophylline interacts with many other meds, always tell your pharmacist about any other prescriptions, over‑the‑counter drugs, or supplements you use. Antibiotics like erythromycin, certain antidepressants, and heart medications can raise Theophylline levels.
Regular blood tests are the best way to stay safe. Your doctor will likely check your level after a few weeks and then every few months. Keep a list of any new symptoms and share them at each visit.
Remember, Theophylline isn’t a first‑line treatment for most lung problems, but it can be a solid addition when inhalers don’t cover everything. Follow the dosing schedule, watch for side effects, and keep communication open with your healthcare team.
