Corvental D 500mg capsules for dogs are used for the treatment of congestive heart failure as well as bronchitis. The large, hard gelatin capsules have Th500 written on them. Each Corvental D 500mg capsule contains 500mg of Theophylline with a sustained release mechanism. This means that the Theophylline dissolves over a longer period of time so it enters the bloodstream at a slow and steady pace. The advantage of giving a drug with a sustained release mechanism is that the medication does not have to be given as often as drugs that enter the bloodstream at a much faster and less steady rate.

Theophylline should be used with caution in patients with liver disease. Do not give to epileptic patients.


If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.
