Read this Medication Guide before you start using SIGNIFOR and each time you get a refill. There may be new information. This information does not take the place of talking to your doctor about your medical condition or your treatment.

What is the most important information I should know about SIGNIFOR?

SIGNIFOR can cause serious side effects, including:

  • Low cortisol levels in your blood (hypocortisolism). Tell your doctor right away if you have any signs and symptoms of hypocortisolism. Signs and symptoms of hypocortisolism may include:

    • fatigue
    • loss of appetite
    • nausea
    • vomiting

If you get hypocortisolism while taking SIGNIFOR, your doctor may change your dose or ask you to stop taking it.

    • excessive thirst
    • high urine output

Getting started:

Step 1: Wash your hands well with soap and water and dry them.

Step 3: Look at the SIGNIFOR ampule. Check that the ampule is not cracked or broken and that the liquid medicine in the ampule is clear and colorless.
Do not use SIGNIFOR if the ampule is cracked or broken or if the liquid looks cloudy or contains particles. Take the whole box back to the pharmacy and get a new one.

Preparing your SIGNIFOR dose:

Step 5: Hold the SIGNIFOR ampule at the bottom with 1 hand. With your other hand, tap the top of the SIGNIFOR ampule with your finger to make sure there is no liquid in the top of the ampule when you open it (See Figure D).

Step 7: Open the sterile needle package. Place the needle on the top of the syringe. Push down on the needle and twist it clockwise until it is tight (See Figure F).

  • If you have been told to use 1 long and 1 short needle, you should use the long needle for this step.

After injecting your SIGNIFOR dose:

  • Put your used needles and syringes in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and syringes in your household trash.
  • If you do not have a FDA-cleared sharps disposal container, you may use a household container that is:

    • upright and stable during use,
    • leak-resistant, and
    • properly labeled to warn of hazardous waste inside the container.
