Prescription Item (POM-V)
Corvental-D capsules contain theophylline, a prescription-only medicine indicated for bronchitis and congestive heart failure in dogs.
Choose the strength your vet prescribes.
Form: Hard capsule, taken by mouth once a day.
Corvental-D capsules contain theophylline, a medicine from the same family as caffeine. Your vet may prescribe Corvental-D if your dog has bronchitis (inflamed airways) or congestive heart failure (when the heart struggles to pump blood around the body).
Each strength looks different. The 100mg capsule is blue and white, marked “Th100”. The 200mg is green, marked “Th200”, and the 500mg is a longer green capsule marked “Th500”.
Additional information
Always use Corvental-D exactly as prescribed by your vet. Full product information: Corvental-D SPC on the VMD Product Information Database.
Ask your vet or pharmacist if you are unsure how to give it.
