Medical Overview
Theo-Dor is listed as Respiratory containing Theophylline Extended-Release. A respiratory medicine used for allergy, asthma, or airway symptoms depending on dosage form.
Theo-Dur (theophylline ER) — the semi-retired centenarian bronchodilator: third-line oral add-on with an infamous narrow window (levels 5-15 modern) and pharmacology’s classic perturbation list — ciprofloxacin/clarithromycin/fluvoxamine push it toxic, smoking burns it (cessation silently raises it), fever raises it. New nausea + palpitations + insomnia = level before the next dose; every antibiotic course asks about it.
