Going generic with your pet's drugs: What you need to know

December 21, 2009 / (6) comments


As our House and Senate debate the merits and pitfalls of bringing affordable healthcare to the American masses, the parallels between human and animal medicine are unmistakable. One area in which this is more the case than most revolves around the unbelievably big savings that can come from going generic with your pet drugs...and the unfortunate downside of doing so for some.

 

Just as your health insurance carrier wants badly to limit your consumption of super-pricey on-patent drugs, you the pet owner want unfettered access to the least marked-up drugs for your pets. In both cases that inevitably means seeking generics in lieu of fancy brand names that in almost all cases offer no substantive inducements to warrant the big price differential. Because once that brand-name blockbuster drug goes off patent all bets are off. In comes the generic competition to drive everyone’s prices down .

 

In other words, going generic is nearly always preferable financially. After all, the FDA requires that generic drugs be chemically the same (same ingredients, just as pure, just as stable) and offered at the same dosages in the same preparations. They’re identical––in theory anyway. So why not get the cheaper stuff?

 

Great question. And not always so easily answered. Why? Because individuals who suffer some conditions may have varying responses or reactions to certain generics. But there’s no easy way to know whether the generic you seek is one that may not serve you or your pet as well as the brand name. In fact, in most cases it’s all about time-consuming trial and error. But not always...

 

Which is why some consumer groups are there to help you reach an informed personal decision on the subject. The Consumer Federation of the Southeast has even issued a six-question card that helps you arrive at a decision with your doc and pharmacist’s help.

The implication, of course, is that sometimes humans are switched over to generics against their physicians’ recommendations so their insurance companies can save a buck...at the expense of the patient's personal health.

 

Interestingly, the opposite problem is what plagues vet medicine. While it’s true that generics don’t always make ideal substitutes (consider the case of Zyrtec and its generic, cetirizine, profiled recently here), the high cost of brand-name pet drugs and the dearth of animal-only generics means pet owners are often forced (by law) to endure high prices as a result of legal maneuvers and lack of competition in small animal pharma. (Here’s a post on this.)

 

We may complain about our generics as human patients––and no doubt deserve to should we be strong-armed into use medications our docs don't believe are in our best interest––but should nevertheless remain aware that generics are our friends in almost all instances.

 

Because ultimately, a system whereby generics flow more freely bodes better for animal health. Generic drugs mean more competition, more choices, lower prices and greater access to care. Even if it means my clients will need cards like the one above, I'm thinking it's a good thing. What say you?

PJB: Agreed. They may be just as pure, just as stable. But they will never be the exact same thing as long as different "inert" ingredients are deemed OK.

"FDA requires that generic drugs be chemically the same (same ingredients, just as pure, just as stable)"  If that were the case, there wouldn't be any difference between the brand and generic ever except for manufacturing errors.  Sorry.  Not true.  It requires the generic to be a bioequivalent and all other ingredients may be entirely different.


"chemically identical to their branded counterparts... inactive ingredients may vary"  I suspect a chemist would disagree with part one based on part two.  As a patient, I can tell the difference between codeine phosphate and codeine sulfate in 30 minutes.  One will work and the other won't.  Bioequivalent my hooha!

THIS IS IMPORTANT TO KNOW!:


teri: There ARE some less expensive alternatives for canine arthritis medications:


1) carprofen (the generic for Rimadyl) is now available in another FDA approved-for-dogs form. It's technically not generic because it's got to be approved for dogs to legally compete with Rimadyl. It's called Novox and it's much cheaper


2) meloxicam (generic for Metacam) is legally available as a generic for dogs who won't take the liquid version. 


Here's the deal: As long as there's a species-specific generic medication out there your veterinarian can prescribe it. If there's no dog- or cat-specific generic (only a human generic) for a dog or cat brand-name drug, your veterinarian is legally enjoined to refuse you access to it (really).


If, however, your dog (for example) won't take liquid meds and the animal version comes in a liquid only, you can appeal to your veterinarian for the generic human form that comes in a pill and costs a tiny fraction of what the pet-only version costs. 


That means that for Metacam (a couple of hundred bucks for a 100-lb dog every month) you can get a $4 Rx of meloxicam and save HUGE money. But only if you can convincingly argue that 1) your dog does best on this arthritis drug and 2) he won't take the liquid version. Your dog also has to be big enough for the large human dose to get administered whole or be safely halved. Generally speaking, dogs below 75 lbs won't qualify for this generic.


btw, in some states your veterinarian can withhold a prescription (highly wrong, IMO) but most veterinarians won't if you're buying from a reputable online (VIPPS certified) pharmacy or a brick-and-mortar human pharmacy they can rely on.

My 10 year-old Lab takes tramadol (generic for the human drug Ultram) for her hip dysplasia-induced arthritis. The brand-name med would cost me a couple hundred dollars a month. But even the generics have a wide variance from pharmacy to pharmacy. By price-shopping, I was able to get a month's supply (270 tablets,----[2] 50mg. tabs 3 times a day-- even though she doesn't always need to take it 3 times a day) for $11.60, but got prices for the same generic script of up to $72.40). So do your research before you just drop off the script at the closest pharmacy.

I have a dog with epilepsy, and I wouldn't be able to afford her meds if she wasn't on the generic. Right now, she gets Levetiracetam (generic for Keppra) and Phenobarbitol. I pay around $50 per month for Levetiracetam. If I had her on Keppra, it would cost around $375 per month and there's no way I could do it. The only problem I've had with using a generic is that even though I always use the same pharmacy, it doesn't mean I always get the generic from the same manufacturer. For my dog, I think the slight variation can be an issue. In the past, she's had a couple of seizures after I refilled her prescription. Now I'm careful to make the switch gradually. I refill her prescription a week or so before I'm going to run out and then alternate her doses between the old prescription and the new one. Maybe I'm just being paranoid, but since I started doing that my dog hasn't had any seizures following a new prescription.


One other thing I've found, there is a huge variation in what different pharmacies with charge for the same generic drug. If you're struggling with the costs of your pet's medications, it's really worth it to call around. I've seen Levetiracetam for anywhere between $40 and $140 at different local pharmacies.  I've had the best luck with Costco, and most states don't allow "members only" pharmacies so in places like Costco you can use the pharmacy without a membership.

I wish there were some generic arthritis drugs for dogs.  Derramax seems to be the most affordable, but still about $40 a month, for a medium sized dog.  Glad he is not bigger.  His thyroid and heart meds are also people drugs, and I can get generic.  (his heart meds I can get at Sams for $4 a month)
