Rated 4 out of 5 by from 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%!

Rated 5 out of 5 by from Wonderful product My dog has breathing problems due to a collapsing trach and heart problems. As she gets older the breathing has gotten so hard for her that just picking her head up was hard. Our wonderful Vet put her on Theophylline 3 times a day. By the end of the second day she was breathing easier and by the end of day 4 her breathing was slow and steady and we can hardly hear her now. Plus she has more energy. This is a wonderful product. I'll always keep her on it. I pray they don't stop making it.

Rated 5 out of 5 by from What a GREAT Price!! Bonnie has been on Theophylline for about 2 yrs now. I have been buying it at a local drugstore because I didn't realize I could buy it online. Bonnie is very small (5#) and needs a really small dose. BUT the "Compounding Pharmacy" where I was getting it charged $85 for 2 months supply. Now I have a 6month supply for $20 and I haven't noticed any difference since changing to the tablets. I will cut them wihtout a problem. If they don't cut well, I don't mind discarding a piece due to the low cost. Thank You PetMeds!!

Rated 5 out of 5 by from Theophylline is a Lifesaver My Yorkies, Honey & Hercules,both take Theophylline every day. They have been on it for years, with no ill effects. Honey will be 14 years old on Christmas Eve and Hercules is now 10 years old. I attribute their longevity in part, to the use of Theophylline. It is a real lifesaver. It keeps their collapsing trachea problems from causing breathing incidents.

My 11pm dog has taken 1/4 tab of a regular 100 mg tab  2xday for over a year. That type is on back order & not aavailable. Can she take 1/4 tab 2x day of s 100 mg tab of Theophylline ER. 

Asked by: Katy
No, your dog should take 1/2 of the 100 mg ER tab ONCE a day since this is an extended release tablet. Be sure to cut the tablet on the scored line and not anywhere else, since each half is time released.
Answered by: Christine
Date published: 2017-06-03

The suggested dosage for dogs is 2.25 to 5 grams of medication per pound of weight of the pet. What is the equivalent dosage in the ER Theophylline? My Vet prescribed 50mg bid for my dog of regular Theophylline.  Can the prescription be for 100 tabs?

Asked by: Lydia
Yes, that's correct. Instead of giving 50 mg twice daily of the immediate release theophylline, you could give 100 mg daily of the extended release theophylline. However, your veterinarian would need to approve this change first.

My dog is only 5 pounds. I would have to break this pill many times but it says you shouldn't because it's time released. Do you have this in smaller mgs?

Asked by: Debbie nicki
This medication can only be cut in half on the scored line. Each half is time released. However, if you need to give less than 50 mg, you would not be able to do this.
Answered by: Christine
Date published: 2017-06-03

If the tablet is not t be broken then why is it scored? It makes me uncomfortable giving my dog 1/2 a tablet but this is what was prescribed.

Asked by: Patti
The tablet can be cut only where it is scored. It is specially formulated to release its contents over an extended period of time. It was formulated so it can be cut on the scored line and still release over an extended period. However, if the tablet is crushed or chewed anywhere other than on the scored line all of the contents will be released at once and may lead to an overdose.

Why doesn't this med come in smaller doses? My dog would only need 1/8 of this pill daily.

I currently get the liquid med from a compounding pharmacy n this would be a lot cheaper. My dog is only 3.5 pds n takes his liquid med 2x a day. What r your thoughts? Ty!
Asked by: Sheila
Sheila they have the dosage for the product wrong. The dosage they quote on the page is for regular theophylline, but they are selling the extended-release.

How is theophyline normally dosed for a 12 lb asthmatic cat?

I am seeing a variety of ranges for typical veterinarian prescribed doses, but my Vet has suggested 100mg every 12 hours for my 12 lbs cat. This seems awfully high to me from all the literature I have read. Should I question this dose and seek clarification.

I had the same problem. The literature you read, including what they have here, is NOT for the extended relief tablets. The 2 mg per pound is for non-extended relief tablets.

My vet won't prescribe for pedmeds.

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?
Asked by: canuck77
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!

Theophylline

I have finally found a way to get this down my cat. Greenies Pill Pockets...but I can only fit a half of the 100 mg tablet in one of them..and that's all I can get him to take at a time... Perhaps an hour later, I try to get him to take the other half in another pocket. I have read on here that they should not be split. Is this going to be dangerous for my cat...there is a little bit of chewing involved with his taking the pill pocket, too. [I can't handle him to force it in his mouth with any "contraption"]
Asked by: canuck77
The theophylline tablets are scored so it is ok to cut in half along the score line but no more than that, it would be best if he can take it without chewing but I understand that might be difficult.

My 15 year old lasha aphso has been taking lasix for quite some years now. His vet's diagnose liquid in his lungs and severe heart murmur. Enalapril 2.5 mg is also one of his med
Asked by: Linda
Theophylline ER is not a replacement for Lasix (furosemide). In some cases theophylline ER is given along with Lasix and enalapril for the treatment of fluid in the lungs. Theophylline ER helps open the bronchioles in the lung to help the pet breath easier. Lasix is a diuretic which helps remove excess fluids from the body.
