Lantus® insulin should be administered as directed by your veterinarian. Your veterinarian will determine the correct dose of insulin need for your pet by means of a blood glucose test. Follow your veterinarian's instructions as doses may vary over time. Use vial within 28 days of first puncture, discard unused portion. 

Injections should be given subcutaneously, just under the skin. Be sure to rotate injection sites to prevent skin problems at the injection site. Pinch a fold in the skin to create a small space for the needle. Insert the needle into the center of the fold as instructed by the veterinarian. Inject the drug by pushing the plunger as far as it will go. Withdraw the needle and be careful to not stick yourself. Dispose the needle immediately in a proper sharps disposal container.  

Insulin syringes and sharps containers are sold separately.  Use only sterile needles/syringes and use each needle/syringe only once.  Injectable medications require needles and syringes.  Those items are purchased separately.  Please ask your veterinarian for a recommendation for the correct needle/syringe sizes for your pet.

Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give 2 doses at once.

Side effects may include hypoglycemia. Signs include hunger, nervousness, vocalization, anxiety, muscle tremors, ataxia, and papillary dilation. If there are signs of hypoglycemia, offer the pet some food or oral dextrose. Positive response should occur within one to two minutes. Prolonged hyperglycemia can result in seizures, coma, and death. Severe hypoglycemic signs require prompt veterinary intervention.

Other side effects may occur. If you notice anything unusual, contact your veterinarian.

The following drug interactions that may occur with insulin include: Beta-adrenergic blockers, clonidine, resperidine, and digoxin. Drugs that may increase hypoglycemic activity of insulin (resulting in low blood sugar) include: captopril, enalapril, alcohol, anabolic steroids, beta-adrenergic blockers, MAOI's, guanethidine, phenylbutazone, sulfinpyrazone, sulfonamides, tetracycline, and aspirin, or other salicyclates. Drugs that may decrease hypoglycemic activity of insulin (resulting in high blood sugar) include: epinephrine, estrogen/progesterone combinations, furosemide, glucocorticoids, isoniazide, phenothiazine derivatives, thiazide diuretics, and thyroid hormones. Serum potassium levels can fluctuate in combination with digoxin and insulin and additional monitoring may be needed. Contact your veterinarian if your pet experiences any unusual reactions when different medications are given together.

Make sure to tell your veterinarian what other medication or supplements you are giving your pet. Dietary changes may also affect insulin requirements. Quite often your veterinarian may prescribe two different medications, even if a drug interaction may occur. In this case, your veterinarian may vary the dose and/or monitor your pet more closely.
