Convenia Warning

December 6th, 2019 at 9:27 am EDT
Hello Friend,

Welcome to Friday :-)

Say you are looking to AVOID some of the potential unwanted side effects of Conventional Medication..such as those from Convenia...

There are sooooo many other natural options.

In fact there are over 1623 remedies in my Manual of Natural Health for Dogs and Cats here:

Convenia Can Have Serious and Fatal Side Effects

Dr Lisa Pierson of has written extensively about this drug. Here is some of what is on her site:

Convenia (manufactured by Zoetis) is an injectable long-acting antibiotic that is labeled for the treatment of skin infections in cats and dogs.  It exerts its antibacterial effects for approximately 1-2 weeks but stays in the body for over 2 months. 

This is in contrast to antibiotics that are rapidly cleared from the body and need to be administered 1 - 2 times per day.

Given how difficult it is to medicate some cats, this 'long-acting' property sounds great, right?

Unfortunately, the old adage, "If it sounds too good to be true, it probably is", rings very true with respect to the use of Convenia in some cases.

Most people are aware of the fact that all drugs have potential side effects with some being more significant/life-threatening than others so we need to be mindful of these side effects when any chemical is put into a living being, not just Convenia.

That said, with regard to Convenia, it is important to consider the fact that if a patient has an adverse reaction to Convenia there is no way to retrieve this long-acting drug from his body.

If an adverse reaction occurs after a short-acting drug is administered, the patient has a much greater chance of living through the event (if other than acute anaphylaxis) because the body will clear the offending drug, hopefully, within hours - not months, as is the case with Convenia.

Note what is stated on the Drug Insert

Anaphylaxis has been reported with the use of this product in foreign market experience. If an allergic reaction or anaphylaxis occurs, CONVENIA should not be administered again and appropriate therapy should be instituted. Anaphylaxis may require treatment with epinephrine and other emergency measures, including oxygen, intravenous fluids, intravenous antihistamine, corticosteroids, and airway management, as clinically indicated.

Adverse reactions may require prolonged treatment due to the prolonged systemic drug clearance (65 days).
FOREIGN MARKET EXPERIENCE: The following adverse events were reported voluntarily during post-approval use of the product in dogs and cats in foreign markets: death, tremors/ataxia, seizures, anaphylaxis, acute pulmonary edema, facial edema, injection site reactions (alopecia, scabs, necrosis, and erythema), hemolytic anemia, salivation, pruritus, lethargy, vomiting, diarrhea, and inappetance.

The most common reactions I have read reports of are anemia, tremors/ataxia, seizures, diarrhea, lethargy, anorexia, and death.

To repeat what I said above, all drugs have side effects but it is my opinion that Convenia is being administered far too often when there are safer choices available for nearly all cases.

P.S.  For instance, I was visiting my brother Michael on Vancouver Island, and his dog had multiple abrasions on his pads from running over barnacles...

A trip to 'the vet' could easily have resulted in a shot of 'Convenia'..because it's convenient.

BUT with potentially serious side effects.

A less expensive and just as effective option?:  Topical Aloe/Calendula

There are so many other natural options.
