PCI/PI/MG	Patient Counseling Information (PLR format only) - summarizes the information that a health care provider should convey to a patient (or caregiver when applicable) when a counseling discussion is taking place (e.g., a physician prescribing a drug during an office visit, a nurse providing discharge instructions at a hospital, or a pharmacist conveying information at a pharmacy). Patient Information - FDA approved patient labeling. Medication Guide - paper handouts that come with many prescription medicines. The guides address issues that are specific to particular drugs and drug classes, and they contain FDA-approved information that can help patients avoid serious adverse events.

Only NDAs and CDER regulated BLAs are included in this database. ANDAs are not included.

Applications that remain active, even if the product has been discontinued, undergo safety-related labeling changes.

5 Warnings and Precautions

5.7 Severe Cutaneous Adverse Reactions

Newly added subsection:

ZOLADEX can cause severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). SCARs, including SJS/TEN, DRESS, and AGEP, occurred in patients receiving ZOLADEX or other GnRH agonists; including cases with visceral involvement and/or requiring skin grafts [see Adverse Reactions (6.10) and Patient Counseling Information (17.1)].

Monitor patients for the development of SCARs.

If a SCAR is suspected, interrupt ZOLADEX until the etiology of the reaction has been determined. Consultation with a dermatologist is recommended. If a SCAR is confirmed, or for other grade 4 skin reactions, permanently discontinue ZOLADEX.

6 Adverse Reactions

6.10 Postmarketing Experience

Additions and/or revisions underlined:

…

Skin reactions: SJS/TEN, DRESS, AGEP, dermatitis exfoliative, bullous dermatitis, and erythema multiforme.

PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined:

Severe Cutaneous Adverse Reactions

Inform patients that severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), which may be life threatening or fatal, may occur during treatment with ZOLADEX. Advise patients to contact their healthcare provider or seek medical attention right away if they experience signs or symptoms of SCARs, e.g., a prodrome of fever, flu-like symptoms, mucosal lesions, progressive skin rash, or lymphadenopathy [see Warnings and Precautions (5.7) and Adverse Reactions (6.10)].

5 Warnings and Precautions

5.10 Clinical Depression

Newly added subsection:

Depression may occur or worsen in women during treatment with GnRH agonists including ZOLADEX 3.6 mg [see Adverse Reactions (6.4, 6.5, 6.10)]. Carefully observe women for depression, especially those with a history of depression and consider whether the risks of continuing ZOLADEX 3.6 mg outweigh the benefits.
Women with new or worsening depression should be referred to a mental health professional, as appropriate.

6 Adverse Reactions

6.10 Postmarketing Experience

Additions and/or revisions underlined:

The following adverse reactions have been identified during post-approval use of ZOLADEX. 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.
Bone Mineral Density: Osteoporosis, decreased bone mineral density and bone fracture in men [see Patient Counseling Information (17.1) and (17.2)].

…
Other Adverse Reactions: Psychotic disorders, convulsions and mood swings, including depression; suicidal ideation and attempt in women.

PATIENT COUNSELING INFORMATION

17.2 Females

Additions and/or revisions underlined:

…

Those adverse events occurring most frequently in clinical studies with ZOLADEX are associated with hypoestrogenism; of these, the most frequently reported are hot flashes (flushes), headaches, vaginal dryness, emotional lability, change in libido, depression, sweating and change in breast size. Inform patients that depression may occur or worsen during treatment with GnRH agonists, including ZOLADEX, especially in patients with a history of depression. Advise patients to immediately report thoughts and behaviors of concern to healthcare providers [see Warnings and Precautions (5.10)]. Clinical studies in endometriosis suggest the addition of Hormone Replacement Therapy (estrogens and/or progestins) to ZOLADEX may decrease the occurrence of vasomotor symptoms and vaginal dryness associated with hypoestrogenism without compromising the efficacy of ZOLADEX in relieving pelvic symptoms. The optimal drugs, dose and duration of treatment has not been established [see Dosage and Administration (2.3) and Adverse Reactions (6.5) and (6.7)].
