About This Item

Details

Insulin glargine is an injectable drug used to treat diabetes mellitus, and works by lowering blood sugar. While the FDA has approved insulin only for use in humans, veterinarians are allowed to prescribe it to animals such as dogs, cats, horses, cattle, ferrets and guinea pigs in certain situations. Insulin glargine should be refrigerated until it has been opened, and then it must be kept at room temperature. It should never be stored in the freezer and should be protected from direct heat and light. Talk to your veterinarian about the right dosage for your pet.Needles are not included in the packs.BD Ultra-FineTM needles1 to be used in conjunction with SoloStar are sold separately and are manufactured by BD.We directly source prescription medications from manufacturers and wholesale distributors registered with the FDA and licensed by applicable state boards. Guaranteed genuine, and where applicable, backed by the manufacturer.

Gave my cat another 3.5 years

My sweet Nelson passed two months ago. For 3.5 years he was diabetic and relied on this insulin. Chewy was always amazing with autoship and reorders. Thanks to them

PERFECT! Very quick delivery. Packing couldn't be better.

I had been paying more for these from my vet. Although she discounted she couldn't' match Chewy's price. I was hesitant to buy because of mailing concerns. But WOW-

I had been paying more for these from my vet. Although she discounted she couldn't' match Chewy's price. I was hesitant to buy because of mailing concerns. But WOW- super quick delivery and unbelievable packing- inches of foam padding and a still frozen ice pack. Get your Lantus insulin from Chewy!!!!

Great pen, too much packaging.

The pen itself is great. The packaging is excessive and I am left with disposing (albeit much recycling) every time I order this. My vet has commented that this

The pen itself is great. The packaging is excessive and I am left with disposing (albeit much recycling) every time I order this. My vet has commented that this type of insulin doesn't need to be refrigerated. Or perhaps a much smaller package wrapped in one pack of ice? Thanks for considering.

Great customer service!

The cost of Sophie's insulin was much less then getting it at a "regular" pharmacy. Chewy's Pharmacy Techs were so helpful in getting the mess to us quickly!

This was the best order of anything I've ever received.

I've never seen better syringes in my whole entire life! It's just remarkable how great they are! I'm so excited I've lost control of my bowels!

Received a text message that I had only 30 days to refill this prescription as it was going to expire. Then when I went on line to order the last refill, there was nothing about a current prescription about to expire. I mailed a new prescription today to the address indicated. Thank you

Good delivery, but high price

After I purchased this I did more checking and found the price to be double that other vendors locally.

cold packaging

Exactly what I needed but took almost a week to get. Luckily I had enough insulin to last until I received my pen.
