Coupons for Lantus

Lantus, also known as insulin glargine, is a laboratory-created drug intended to mimic a hormone secreted by the pancreas. It is used to treat type 1 or type 2 diabetes and is indicated to lower glucose levels in the bloodstream.

Lantus is a long-acting form of insulin used to stabilize blood sugar levels over a longer period of time. It may be administered by a physician for other purposes than listed in this medication guide.

Important Information

Lantus is used as an integral part of a diabetes control regimen. However, it is usually administered in conjunction with diet, exercise, weight control, foot care, eye care, dental care, and blood sugar testing. Special consideration of all aspects of diabetes should be monitored closely, as glucose fluctuations could occur.

Blood sugar levels should be checked daily and if you suspect your sugar is too high or low, unless you are advised otherwise by your physician. You should be aware of the symptoms of high blood sugar and low blood sugar.

Symptoms of high glucose, known as hyperglycemia, could include:

  • Thirst
  • Frequent urination
  • Hunger
  • Dry mouth
  • Fruity breath odor
  • Drowsiness
  • Dry skin
  • Blurred vision
  • Weight loss

If your sugar levels frequently run high, your Lantus dose may need to be adjusted.

Symptoms of low glucose, known as hypoglycemia, include:

  • Headache
  • Hunger
  • Weakness
  • Sweating
  • Tremors
  • Irritability
  • Trouble Concentrating

You should keep glucose tablets or other sugar sources on you at all times in case you experience low blood sugar.

Before Using Lantus

Do not use Lantus if you are allergic to insulin glargine. Inform your physician if you have any kidney or liver disease. Lantus is categorized by the FDA as category C, unknown if it may cause harm to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant. It is unknown if Lantus is passed into breast milk, so inform your doctor if you are breastfeeding.

How is Lantus Used?

Lantus is injected by a small needle under the skin. You should be taught by your healthcare provider how to properly use this medication at home. Lantus should not be mixed in the same syringe with other insulin types but may be used in conjunction with a short acting insulin.

Lantus liquid should be clear, thin liquid. Do not use if it has changed color, become cloudy, or particles have appeared in the liquid.

Injection areas should be rotated with each dose. Your physician will inform you of acceptable areas of the body to use for injection sites. Disposable needles should be used only once, then properly disposed of. Needles should never be shared due to the risk of blood-born diseases.

Keep all scheduled appointments with your doctor. Check your blood sugar regularly and if you suspect high or low sugar. Check more often during times of illness, stress, or increased exercise. Follow the diet recommended by your doctor carefully. Wear a medical alert tag or carry an ID card to inform care providers that you are a diabetic in case of an emergency.

Inform your doctor if you are on the following medications:

  • Albuterol (Proventil, Ventolin)
  • Clonidine (Catapres)
  • Reserpine
  • Beta-Blockers such as atenolol (Tenormin, Tenoretic), carvedilol (Coreg), Labetalol (Normodyne, Trandate), metoprolol (Lopressor, Toprol), nadolol (Corgard), propranolol (Inderal, InnoPran), sotalol (Betapace), and others

Side Effects

Emergency medical help should be sought if there are signs of an allergic reaction:

  • Itching
  • Skin rash over the entire body
  • Wheezing
  • Trouble Breathing
  • Fast heart rate
  • Sweating
  • Dizziness or fainting

Hypoglycemia is the most common side effects. Glucose sources such as orange juice, glucose tabs, or hard candy should be kept with you. Symptoms include headache, hunger, weakness, sweating, tremors, irritability, rapid breathing, fast heartbeat, fainting, or seizure. Severe hypoglycemia can be fatal.

Injection areas may itch, swell, become reddened, or have thickened skin. Inform your physician of these side effects.
