How long does Theophylline stay in your body?

The elimination half-life of theophylline is about 8.7 hours on average (range roughly 6 to 13 hours) in otherwise healthy non-smoking adults 16-60 years — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is the elimination half-life; the label's Table I reports it directly and theophylline follows one-compartment-like kinetics with no clinically relevant longer-lasting active metabolite in adults and it is not a prodrug. The half-life is highly variable and rises markedly in several named populations: elderly (>60 years, normal cardiac/liver/renal function) about 9.8 h (range 1.6-18); liver disease prolongs it substantially - cirrhosis about 32 h (10-56), acute hepatitis about 19 h, cholestasis about 14 h; also longer in acute pulmonary edema (~19 h), sepsis with multi-organ failure (~19 h), and 3rd-trimester pregnancy (~13 h). Because theophylline is cleared by hepatic metabolism, the label ties prolongation to liver dysfunction and age rather than to kidney impairment (renal impairment is not listed as prolonging half-life in adults). The kinetics are non-linear, so half-life increases further at serum concentrations above ~20 mcg/mL. Half-life is shorter in smokers, children, and hyperthyroidism.

Frequently asked questions

What does Somophyllin-T treat?

Somophyllin-T (Theophylline) may be used to treat apnea, asthma, bradycardia, bronchial spasm, bronchitis, pulmonary emphysema, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.

How much does Somophyllin-T cost?

Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.86 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins. Pharmacies pay less for a same-class option, Cromolyn Sodium — about $0.60 on the same basis.

Is there a coupon or discount for Somophyllin-T?

pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Somophyllin-T.
