Aminophylline is a bronchodilator, which relaxes the airways and makes breathing easier.

For: Cats and Dogs


  • Relaxes bronchial smooth muscle to ease air passages
  • Used in the treatment of heart failure and pulmonary edema (fluid in the lungs)
  • Makes it easier for pets to breathe

  • Aminophylline is a bronchodilator, which opens up the large airways in the lungs and increases the amount of airflow.

    How it works

    Aminophylline is a bronchodilator that works by relaxing smooth muscles in the large airways in the lungs. This increases the diameter of the airways and allows more air to flow through. Aminophylline also helps the body get rid of excess fluid through the kidneys.

    Prescription Required


    Dosage & Administration

    Aminophylline is given orally. Give the medication at the same time(s) every day to maintain a constant blood level. Always follow the dosage instructions provided by your veterinarian. If you have difficulty giving the medication, contact your veterinarian.

    This medication should only be given to the pet for whom it was prescribed.

    Possible side effects of Aminophylline: May cause loss of appetite, nausea, vomiting, diarrhea, or nervousness at the beginning of treatment. These side effects usually disappear after a short time. If they do not, or your pet has a rapid heartbeat, or an increase in appetite, drinking or urination, contact your veterinarian.

    May cause seizures at high doses. If so, contact your veterinarian immediately. May cause or worsen abnormal heart rhythms.

    If your pet experiences an allergic reaction to the medication, signs may include facial swelling, hives, scratching, sudden onset of diarrhea, vomiting, shock, seizures, pale gums, cold limbs, or coma. If you observe any of these signs, contact your veterinarian immediately.

    If you miss giving a dose: If you miss a dose, give it as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to the regular schedule. Do not give two doses at once.

    If you overdose the pet: May see seizures, fever, or rapid and irregular heart rates. An overdose can be fatal. If you know or suspect your pet has had an overdose, or if you observe any of these signs in your pet, contact your veterinarian immediately.

    What should I avoid while giving Aminophylline to my pet: Consult your veterinarian before using Aminophylline or theophylline with vitamins, supplements, or any other medications, especially phenobarbital, phenytoin, cimetidine, erythromycin, allopurinol, thiabendazole, clindamycin, lincomycin, phenytoin, lithium carbonate, or pancuronium, beta-blockers (certain heart medications such as propranolol), ciprofloxacin or enrofloxacin (Baytril®), ephedrine, halothane (an inhalant anesthetic gas), and ketamine, since interactions may occur.

    Who should not take it? Aminophylline is not for use in animals hypersensitive (allergic) to it or xanthines including theobromine and caffeine. Aminophylline should not be used in animals hypersensitive to ethylenediamine. Use caution when using Aminophylline in very young or obese animals; animals who are older or debilitated; or those that have severe heart disease, irregular heartbeats, stomach ulcers, hyperthyroidism, liver or kidney disease, hypoxia (lack of oxygen to the cells), high blood pressure, or a history of seizures.
