What is Cephalexin?

Cephalexin is a broad-spectrum antibiotic available as capsules or suspension used to treat bacterial infections. Cephalexin is an antibiotic belonging to a class of drugs called cephalosporins that fight bacteria in the body. It can be used to treat infections such as bronchitis, as well as ear, skin, and urinary tract infections. Cephalexin may also be used for purposes other than those listed. Cephalexin requires a prescription from your veterinarian.

For:

  • Also treats infections of the urinary tract, respiratory tract, bones, and joints
  • Can prevent secondary infections
  • Sold affordably by individual capsules

How does Cephalexin work?

Cephalexin is a cephalosporin antibiotic. Cephalosporin antibiotics suppress the growth of micro-organisms such as bacteria, fungi, or protozoa.

What is the most important thing I should know about Cephalexin?

Cephalexin is an antibiotic belonging to a class of drugs called cephalosporins that fight bacteria in the body. Cephalexin can be used to treat infections such as bronchitis as well as ear, skin, and urinary tract infections. Cephalexin may also be used for purposes other than those listed.

What should I discuss with my veterinarian before giving Cephalexin to my pet?

Tell your veterinarian if your pet has ever had an allergic reaction to another penicillin or to a cephalosporin. Tell your veterinarian if your pet has kidney disease, or a stomach or intestinal disease. Tell your veterinarian if your pet is pregnant or lactating. Cephalexin liquid suspension contains sucrose which may affect the treatment of diabetic pets.

How should Cephalexin be given?

Give this medication exactly as directed by your veterinarian. Cephalexin can be given with or without food. Give all of the cephalexin even if your pet appears to be better. Symptoms may improve before the infection is completely treated. Store capsules at room temperature away from moisture or heat. Store the liquid suspension in the refrigerator. Discard any unused liquid suspension after 14 days.

What are the potential side effects of Cephalexin?

Stop giving cephalexin and seek emergency veterinary medical care in the event of an allergic reaction (shortness of breath; hives; swelling of the lips, tongue, or face; rash; or fainting), severe nausea, vomiting or diarrhea, mucus or blood in the stool, or unusual bleeding or bruising. Other less serious side effects such as mild nausea, diarrhea, or yeast infection may be more likely to occur. Continue to give cephalexin and notify your veterinarian if these symptoms occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to your pet.

What happens if I miss giving a dose of Cephalexin?

Give the missed dose as soon as you remember, then try to evenly space the rest of the doses for that day until you can return to a normal schedule. Do not give a double dose unless otherwise directed by your veterinarian.

What happens if I overdose my pet on Cephalexin?

An overdose of Cephalexin may result in vomiting and/or diarrhea. If you suspect your pet has experienced an overdose, consult your veterinarian or emergency veterinary clinic.

What should I avoid while giving Cephalexin to my pet?

There are no restrictions on food or activity during treatment with cephalexin unless otherwise directed by your veterinarian.

What other drugs will affect Cephalexin?

Before giving cephalexin, tell your veterinarian if your pet is being given another antibiotic (for the same or a different infection), probenecid, or a loop diuretic such as furosemide or warfarin. You may not be able to give cephalexin or you may need to have the dosage adjusted. Drugs other than those listed here may also interact with cephalexin. Talk to your veterinarian or pharmacist before giving any prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.

Customer Reviews
Cephalexin is rated 3.6 out of 5 by 41.
Rated 5 out of 5 by from Cephalexin My precious husked was sick 4 months ago and I took her to the vet. I did not have $400 to take her again to the vet 2 months later for the same thing since the meds they gave her did not work. Frustrated I ordered from this website after much research. Wow, she even received a free treat. They went above and beyond for us and my fur baby was so much better after 3 days. Thank you for wonderful customer service.

Rated 4 out of 5 by from Works Fairley Well My 13 year old lab had a flaming infection on the side of her face. She wouldn't leave it alone so it bled and was a mess. I used this drug, Welfare Allergy pills (to stop the itching)and an Elizabethen collar. Wrapped in Kraft cheese and treated at 6am, 2 pm and 10pm. Within two weeks the collar was gone and she started to recover. She has been on these for 70 days and was on her way to recovery. After stopping the stink aand rot started to return. So even after 70 days treatment, this stuff didn't kill all the bad guys. Either she will be on this until her brain cancer gets her or we will try another method. But I would recommend these to fix smaller infections anytime.

Rated 5 out of 5 by from Cephalexin Eddy is a collie with a very long nose, he has a tendancy to get sinus infection for some reason, the only thing that helps him is Cephalexin. within a matter of hours he is breathing better and mucus is gone. The only bad part is once he is off for a couple months, he seems to come back to the infection. Not sure why...but this drug is a miracle for him. We Love Eddy and we Love Cephalexin.

Rated 5 out of 5 by from Works for UTI My German shepherd had a urinary infection. I put her on Cephalexin and she improved immediately. I missed a days dosing, my fault, and she relapsed. Now she is back on it, has no side effects at all and is doing well. I am now very careful to give it every 8 hours.

Rated 1 out of 5 by from Not a good antibiotic for my lab My 2 year old Lab was given this after her ACL surgery. After starting this antibiotic she wouldn't eat, was panting, drooling and lethargic. Not knowing it was the antibiotic we were worried that something had went wrong with the surgery. We took her back to the vet. They did blood work, which all came back good. The vet changed her antibiotic and she was back to normal.
