Theophylline, a methylxanthine derivative, is a medication primarily classified as a bronchodilator used in the management of chronic asthma and COPD requiring maintenance therapy. It functions by relaxing the smooth muscles of the bronchi and increasing the capacity of the lungs to hold air during breathing distress. This oral formulation suits patients needing consistent, around-the-clock management of their chronic airway constriction.

Generic Theophylline Buyer and Patient Handbook in South Africa
What is Theophylline?
Theophylline is a bronchodilator in the methylxanthine class used to treat Asthma and other reversible airway diseases. It relaxes airway smooth muscle and improves breathing during an asthma attack. In South Africa it is approved by the SA Health Products Regulatory Authority (SAHPRA) and is supplied as a pill.
Who Should Use Theophylline?
- Adults with mild-to-moderate asthma who need an oral maintenance option.
- Patients with chronic obstructive pulmonary disease (COPD) where inhaled therapy alone is insufficient.
- Individuals who cannot tolerate inhaled steroids or long-acting beta-agonists.
How Does It Work?
Theophylline blocks adenosine receptors and inhibits phosphodiesterase, leading to higher cyclic AMP levels that keep airway muscles relaxed. Think of it as pressing the “open” button on your airway tubes while you’re breathing. It has a modest stimulant effect on the central nervous system, so it should not be taken in excess.
Why Choose Theophylline?
- Affordable oral option compared with many inhaled combinations.
- Proven track record for decades of use in asthma management.
- Generic formulation provides cost savings while delivering the same therapeutic effect as brand-name products. (Off-label uses exist; discuss with a qualified health professional before considering them.)
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- 400 mg once daily for most adults, or 200 mg twice daily if a lower peak concentration is needed. Adjust based on clinical response and blood level monitoring.
How to Take
- Swallow the tablet whole with a full glass of water.
- Take the dose with food to reduce stomach irritation.
Missed Dose
- If you are less than 12 hours late, take the missed tablet now and continue the regular schedule.
- If more than 12 hours have passed, skip the missed dose and resume the next scheduled dose; do not double-dose.
Overdose
- Call emergency services (112) or go to the nearest hospital.
- Symptoms may include nausea, vomiting, rapid heartbeat, or Seizures.
Special Populations
- Elderly: Start at the lower end of the dose range (200 mg daily) because metabolism slows with age.
- Renal or hepatic impairment: Dose reductions are often required; monitor blood levels closely.
- Pregnancy & breastfeeding: Use only if the benefit outweighs potential risk; discuss with a clinician.
Lifestyle & Diet
- Avoid grapefruit juice as it can raise blood levels and increase side-effects.
- Limit caffeine-containing drinks (coffee, tea, cola) to reduce cumulative stimulant effects.
- Alcohol can increase the risk of dizziness; consume in moderation.
Precautions and Warnings
- Do not use if you have a known hypersensitivity to methylxanthines.
- Monitor for signs of toxicity (tremor, palpitations, Insomnia).
- Regular blood level checks are advisable when dose changes occur or when starting interacting drugs.
