Theophylline sr cost?

Prices for theophylline sustained-release (SR) tablets vary a lot by country, dose, and whether you get generic or brand-name. If you’re in the US, here’s a rough ballpark (before insurance or coupons):

- Theophylline SR 100 mg: roughly $15–$40 for a bottle of 100 tablets
- Theophylline SR 200 mg: roughly $25–$60 for a bottle of 100
- Theophylline SR 300 mg: roughly $30–$70 for a bottle of 100
- Theophylline SR 400 mg: roughly $40–$100 for a bottle of 100

With insurance, coupons, or a discount program (e.g., GoodRx), the price can be much lower. Prices also differ if you use brand-name products versus generics and if you buy a 90-day/mail-order supply.

If you can share:
- Your country
- The exact strength (e.g., 300 mg SR)
- Whether you want generic or brand-name
- If you want the price with or without insurance

I can tailor a more specific estimate or help you find current prices at nearby pharmacies. Also, if you’re starting or adjusting therapy, your clinician should monitor levels because theophylline has a narrow therapeutic window.
