Compare Theochron (branded generic) vs. Qvar RediHaler

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Theophylline (Theo-24, Elixophyllin, Theochron) and Qvar RediHaler (beclomethasone) are both used to help manage asthma, but they work in different ways and have different uses. Theophylline is a nonselective PDE inhibitor that acts as a bronchodilator, relaxing the muscles in your airways to help you breathe easier. It is available in both pill and liquid forms, including generic versions. However, it is not a first-choice medication for asthma or COPD because it requires regular blood tests and can interact with other medications. On the other hand, Qvar RediHaler is an inhaled corticosteroid that reduces inflammation in your lungs to prevent asthma attacks. It is used twice daily and should be taken consistently to be effective. It should not be used for treating sudden asthma symptoms. Unlike theophylline, Qvar RediHaler does not have a generic version. Additionally, Qvar RediHaler can cause fungal infections in the mouth if you don't rinse your mouth after use, while theophylline can cause side effects similar to having too much caffeine such as a headache or trouble sleeping.
