Please contact your veterinarian immediately if you notice any of the following reactions: loss or increase of appetite, nausea, vomiting, diarrhea, nervousness, increased drinking or urination, seizures or abnormal heart rhythms. These symptoms usually disappear after the medication has been given for a while. An allergic reaction is possible in those allergic to Theophylline. Other side effects are possible.
Notify your veterinarian of any other medications, including vitamins and supplements, your pet is taking before using Theophylline. This medication may decrease the absorption of digoxin (blood pressure support). It may also decrease the absorption of folate (folic acid). Other drug interactions may occur.
Do not give Theophylline to pets who are allergic to it or similar medications, such as xanthines, theobromine or caffeine. Pets who are very young, obese, debilitated, elderly, with severe heart disease, irregular heartbeats, stomach ulcers, hyperthyroidism, liver or kidney disease, hypoxia, high blood pressure or a seizure history may have trouble with this medication and it should only be used when your veterinarian thinks the benefits outweigh the risks.
This drug is FDA-approved for human use. However, it is common practice for veterinarians to prescribe such drugs for use in dogs and cats.
Theophylline.

Store in well-closed containers at room temperatures 68° - 77°F. .
Theophylline is an oral tablet that is classified as a bronchodilator. It helps to relax airways and make breathing easier in pets who suffer from multiple respiratory disorders.
Theophylline is given orally preferably at the same time(s) daily exactly as directed by your veterinarian.
Always consult with your veterinarian if you have questions regarding the proper use of Theophylline.
Theophylline causes relaxation of the smooth muscles in the airways and lungs. Muscular relaxation increases the airway diameter and helps maximize the flow of air through them making breathing easier. Theophylline may also assist in draining excess fluid from the body through the kidneys.
Theophylline can help to make breathing easier for your pet but it does not cure underlying illnesses. Theophylline is effective after several hours so it is not effective for acute asthma attacks. Symptoms may return if medication is stopped.
Theophylline has been hard to find. The first Rx I bought from a different company and it took 5 days to get the med. My dog had great trouble breathing over the weekend while I waited. I changed to Chewy Pharmacy and her meds have always been shipped within 24 hours. I'm only baffled by the fact that a 300mg tablet costs more than twice the cost of a 400mg tablet. It just doesn't make sense. I love the Chewy service.
My emotional support dog has an enlarged heart. This medication was $111 for 30 at my local pharmacy. Chewy’s price is less than half of that. I’m on a fixed income but I would do or pay anything for Buddy’s health. The lower price has definitely helped me. I was already buying a lot from Chewy and was surprised when my veterinarian suggested checking their prices. Chewy is great!
My 6 lb dog is on a much smaller dose than offered through Chewy's. My vet found a local compounding pharmacy that makes the liquid suspension. They also ship out of state. Ask your vet about compounding pharmacies.
Aside from lack of choice of strength - pricing per pill is just strange. My vet was out of this med, guess I'll just wait till they get it back in stock. Disappointed....
There seems a problem with the size of this pill? There is no possible way, (no matter how you crush it down ) that is can give this to my cat. Could their be maybe a liquid that i purchase instead of this pill? Anyhow I'll be returning this item. Thank you very much.
