What Drugs Interact With Humulin R?

Humulin R may interact with albuterol, clonidine, reserpine, guanethidine, or beta-blockers. Tell your doctor all medications you are taking.

What Drugs Interact With Lantus?

Lantus may interact with albuterol, clonidine, reserpine, or beta-blockers. Many other medicines can increase or decrease the effects of insulin on lowering your blood sugar.

How Should Humulin R be Taken?

The recommended starting dose of Humulin R for patients 6 years and older is 25 mg once daily in the morning. The dosage of Humulin R may be increased in increments of 10 to 15 mg at intervals of at least 5 days.

How Should Lantus be Taken?

  • Use Lantus exactly as your healthcare provider tells you to. Your healthcare provider should tell you how much Lantus to use and when to use it.
  • Know the amount of Lantus you use. Do not change the amount of Lantus you use unless your healthcare provider tells you to.
  • Check your insulin label each time you give your injection to make sure you are using the correct insulin.
  • Lantus comes in a SoloStar disposable prefilled pen that you must use to give your Lantus. The dose counter on your pen shows your dose of Lantus. Do not make any dose changes unless your healthcare provider tells you to.
  • Do not use a syringe to remove Lantus from your SoloStar disposable prefilled pen.
  • Do not re-use needles. Always use a new needle for each injection. Re-use of needles increases your risk of having blocked needles, which may cause you to get the wrong dose of Lantus. Using a new needle for each injection lowers your risk of getting an infection. If your needle is blocked, follow the instructions in Step 3 of the Instructions for Use.
  • You may take Lantus at any time during the day but you must take it at the same time every day.
  • Lantus is injected under your skin (subcutaneously). Do not use Lantus in an insulin pump or inject Lantus into your vein (intravenously).
  • Change (rotate) injection your sites within area you chose with each dose. Do not use the exact spot for each injection.
  • Do not mix Lantus with any other type of insulin or liquid medicine.
  • Check your blood sugar levels. Ask your healthcare provider what your blood sugar should be and when you should check your blood sugar levels.

  • Do not re-use needles. Always use a new needle for each injection. Re-use of needles increases your risk of having blocked needles, which may cause you to get the wrong dose of Humalog. Using a new needle for each injection also lowers your risk of getting an infection. If your needle is blocked, follow the instructions in the "General information about the safe and effective use of your Pen" section of the Instructions for Use.
