4 Contraindications

Additions and revisions underlined:

CAVERJECT IMPULSE is contraindicated:

  • in men who have a known hypersensitivity to the drug [see Adverse Reactions (6.1)]

  • in men who- have conditions that predispose them to priapism, such as sickle cell anemia or sickle cell trait, multiple myeloma, or leukemia [see Warnings and Precautions (5.1)]

5 Warnings and Precautions

5.7 Needle Breakage

Additions and revisions underlined:

CAVERJECT IMPULSE uses a superfine (29 gauge) needle for administration. As with all superfine needles, the possibility of needle breakage exists. Needle breakage, with a portion of the needle remaining in the penis, has been reported and, in some cases, has required hospitalization and surgical removal. Careful instruction in proper patient handling and injection techniques may minimize the potential for needle breakage. [see Dosage and Administration (2.3) and Adverse Reactions (6.2)].

5.8 Risk of Serious Adverse Reactions in Infants due to Benzyl Alcohol

Subsection title revised

6 Adverse Reactions

6.2 Post-marketing Experience

Additions and revisions underlined:

The following additional adverse reactions have been reported during post approval use of CAVERJECT IMPULSE. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Injury and procedural complication: device malfunction/failure, needle breakage, drug ineffective and drug effect decreased.

  • Not re-use or share needles and to properly discard after use.

Needle Breakage

Advise patients that needle breakage has occurred during self-injection of CAVERJECT. Advise patients to insert the needle perpendicular to the long axis of the penis to avoid bending or breakage of the needle [see Warnings and Precautions (5.7) and Adverse Reactions (6.2)].

Patient Information

What are the possible side effects of CAVERJECT IMPULSE? CAVERJECT IMPULSE may cause serious side effects, including:

. . .

needle breakage. There is a possibility of needle breakage with use of CAVERJECT IMPULSE. To best avoid breaking the needle, you should pay careful attention to your healthcare provider’s instructions and handle the syringe and needle properly. If the needle is bent at any time, do not attempt to straighten it and do not use it. A bent and re- straightened needle is more likely to break.

5 Warnings and Precautions

5.8 Benzyl Alcohol (addition underlined)

The preservative benzyl alcohol contained in CAVERJECT IMPULSE has been associated with serious adverse events, including the “gasping syndrome”, and death in pediatric patients. The minimum amount of benzyl alcohol at which toxicity may occur is not known. The risk of benzyl alcohol toxicity depends on the quantity administered and the liver and kidneys’ capacity to detoxify the chemical. Premature and low-birth weight infants may be more likely to develop toxicity. CAVERJECT IMPULSE is not indicated for pediatric patients.
