Rated 4 out of 5 by from Was working great! Have had my cat on this and now we can't get it anymore. Trying to find something comparable but looks like the compound pharmacy will have to try to come up with something. Very disappointed, my vet also.

Rated 3 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Could I cut this in 4ths to give 1/4 to be 100mg a day ?

Asked by: Karen
Thank you for your question. This is an extended release Theophylline tablet. Cutting or crushing the tablet destroys the release mechanism. Do not cut or crush the tablet unless instructed by your veterinarian.

I see that after not having this product in stock for the longest time, you now have 300mg and 400mg strength. My question: Are the 400mg pills scored? If they are, it would work for my dog, who is prescribed 200mg per day. Please advise

Asked by: Mickey C
Yes, the 400mg theophylline tablets are scored.

My vet prescribed 100 mg theophylline ER every 12 hours. My pharmacy only had 200mg of the 24 hour release capsule. Is this safe to give to a 49 lb 12.5 year old greyhound?

Asked by: Bumbee
The usual dose of theophylline for dogs is 4.5 to 6.8 mg/lb of pet's body weight by mouth every 12 hours. Check with your veterinarian to ensure that your prescription was filled properly.

How do I order Theophylline 150 mg. It isn't offered in the tablet pull-down tab

Asked by: Debbie
Theophylline is not produced in a 150mg strength. This strength may need to be compounded. I would recommend speaking to your veterinarian.
