What is Theophylline?

 
Theophylline Extended Release is a bronchodilator used to open air passages in the lungs. Theophylline requires a prescription from your veterinarian, and is sold per tablet.

For: Cats and dogs
 
Benefits:
Easy to administer

How it works:
Theophylline opens air passages in the lungs by relaxing muscles in the lungs and chest.

Cautions:
The medication is best given on an empty stomach. Theophylline should not be given to pregnant or nursing animals. Theophylline E.R. tablets are scored and may be broken in half. These tablets should not be chewed or crushed.


More Information:
 
Brand Name
Theolair (UCB Pharma), Theo-Dur (Key), Uniphyl (Purdue Pharma)
Generic Name
Theophylline E.R.

What is the most important information I should know about theophylline: Always check the medicine when it is refilled to make sure you are getting the correct brand and type as prescribed by your veterinarian. Ask the pharmacist if you have any questions about the medication you received from the pharmacy. There are many medications that can interact with theophylline. Tell your veterinarian about all the prescription and over the counter medications you give your pet. These include vitamins, minerals, herbal products, and medications prescribed by other veterinarians. Theophylline is not FDA approved for use in veterinary medicine; however, it is a commonly accepted practice for veterinarians to use this medication in dogs and cats. Theophylline is available by prescription in 100mg and 200mg, Extended Release (ER), tablets. The usual dose in dogs is 4.5 to 6.8mg per pound every 12 hours. The usual dose in cats is 2mg per pound every 8 to 12 hours.

What is theophylline: Theophylline is a bronchodilator which relaxes muscles in the lungs and chest. Theophylline is used in the treatment of heart failure, asthma, bronchitis, and pulmonary edema. Theophylline may also be used for purposes other than those listed in this medication guide.

What should I discuss with my veterinarian before giving theophylline: Tell your veterinarian if your pet is allergic to theophylline, or if your pet has stomach ulcers; epilepsy; heart rhythm problems; congestive heart failure; fluid in the lungs; hypothyroid; fever; liver, or kidney disease. Tell your veterinarian if your pet is pregnant or lactating, or if you plan on breeding your pet.

How should this medication be given: Give theophylline exactly as directed by your veterinarian. Do not give the medication in larger amounts, or for a longer period of time than recommended by your veterinarian. Follow the directions on the prescription label. Allow plenty of water for the pet to drink. Theophylline ER tablets should not be crushed, chewed, or broken unless the veterinarian tells you to. The tablet should be swallowed whole so that the medication is released slowly. Breaking the tablet may cause too much of the medication to be released at one time. Store theophylline at room temperature, away from moisture, heat, and light.

What happens if I miss a dose: Give the missed dose as soon as you remember. If it is almost time for your next dose, skip the dose that was missed and give only the next regularly scheduled dose, as directed. Do not give a double dose of this medication unless otherwise directed by your veterinarian.

What happens if I overdose the pet: Call your veterinarian or veterinary emergency room. Symptoms of overdose may include nausea, vomiting, insomnia, tremors, restlessness, uneven heartbeats, and seizures.

What should I avoid while giving theophylline: Do not give this medication if your pet has severe heart disease, liver or kidney disease, hyperthyroid disease, high blood pressure, or stomach ulcers.

What are the possible side effects of theophylline: If any of the following serious side effects occur, stop giving theophylline and seek emergency veterinary medical attention; an allergic reaction (difficulty breathing, swelling of the lips, tongue, face, or hives). Stop giving theophylline and call your veterinarian at once if any of the following side effects occur; seizures; severe nausea and vomiting, and restlessness; coughing up  blood or vomit that looks like coffee grounds; urinating more than normal. Other less serious side effects may also occur. Talk to your veterinarian if your pet experiences mild nausea, loss of appetite, weight loss; restlessness, or insomnia; headache, or dizziness. Side effects other than those listed here may also occur. Talk to your veterinarian about any side effect that seems unusual or that is especially bothersome.

What other drugs will affect theophylline: Tell your veterinarian if your pet is using cimetidine (Tagamet); erythromycin (E-Mycin, Ery-Tab); propranolol (Inderal). Drugs other than those listed here may also interact with theophylline. Talk to your veterinarian or pharmacist before giving any prescription or over the counter medications including vitamins, minerals and herbal supplements.

Where can I get more information: Your pharmacist has additional information about theophylline written for health professionals that you may read.

 

Call your veterinarian for medical advice about any side effects to your pet. You may report side effects to the FDA at 1-800-FDA-1088.

It helps, are the side effects worth it? The medication helped my dogs breathing, but all she did all night long was pace and pant. She kept both my husband and I up all night long. The side effects are far too much to handle for everyone. 03/17/2014
Very Helpful Drug My dog Patches is a 10 yr old Aussie Cattledog with COPD. She weighs approx. 58 lbs which is a little on the heavy side but her health prevents her from getting all the exercise she needs and food is the best thing in her life at this point. She still coughs but not as much and without the Theophylline, she couldn't exist. The cough is also not as deep or harsh. She is on 300 mg per day. 03/14/2014
cat with asthma The product has helped with the asthma although he still coughs but not nearly as much. 11/23/2013
Cough Tex's cough developed over last winter and was getting worse - in mind it was woodstove, my nasty cigs, cats, dust, etc. It is also heart murmur, throat is narrow or swolen and he is getting old! My vet prescribed theophylline two month ago and the cough started to get better right away so of course I will maintain this "cure" but had to save money on future purchases so here I am! Thanks for providing these medications to we, the 99%! 08/06/2013
Same product lower price This medication is the same brand as I got from my vet but about $15 less. The medication was shipped in a very timely manner I am very pleased with my purchase of theophyllin from 1800petmeds. 04/06/2013

Answer: 
We are able to compound the theophylline in a transdermal form that may be applied to your cat's inner ear. Please discuss this with your veterinarian to see if the transdermal would be a good option.

theophylline

I haven't taken my cat to doctor, but seems to have symptoms of asthma. I have 200 mgs of this med for myself, not much money either. Can I give some to my cat? And if so how much? I would like to try to see if works before spending money if possible. Thank you

Answer: 
Do not give your medication to your pet. Dosing for pets is different from humans. It can be very dangerous to give human medication to your cat. Please consult with your vet regarding the proper medication and treatment for your cat.

Theophylline is over $10 for 10- 14 pills. I can get a month's supply here for that price. Pet insurance will only pay a percentage of their costs of around 30 cents a pill. My vet says they do not allow their prescriptions to be filled online like this. Is this normal? They said not for a prescribed medicine...should I look for another vet? Should I not be able to take the prescription and get it filled where I want? How do other people do it?

Answer: 
Your vet is able to do this, they just have to give their okay when you place your order.
Tell your vet you ARE ordering online and that they will get an email regarding the scrip!
If they don't do this for you you definitely need to change your pet's doctor!

Answer: 
Hi Lynn, Normally we contact the vet to obtain an approval, I am sorry you're having this difficulty with getting your medication. I would suggest to ask him for a written prescription that you would be able to use where ever you would like. You would mail that to us and once we receive the original we do not have to contact your vet and we can finalize the order for you.
