5 Warnings and Precautions

5.8 Pulmonary Arterial Hypertension

(Newly added subsection)

Cases of pulmonary arterial hypertension (PAH) have been reported with interferon beta products, including BETASERON. PAH has occurred in patients treated with interferon beta products in the absence of other contributory factors. Many of the reported cases required hospitalization, including one case with interferon beta in which the patient underwent a lung transplant. PAH has developed at various time points after initiating therapy with interferon beta products and may occur several years after starting treatment.

Patients who develop unexplained symptoms (e.g., dyspnea, new or increasing fatigue) should be assessed for PAH. If alternative etiologies have been ruled out and a diagnosis of PAH is confirmed, discontinue treatment and manage as clinically indicated.

17 PATIENT COUNSELING INFORMATION

(Additions and/or revisions underlined)

See FDA-approved patient labeling (Medication Guide and Instructions for Use).

Instruct patients to carefully read the supplied BETASERON Medication Guide and caution patients not to change the BETASERON dose or schedule of administration without medical consultation.

Instruction on Self-Injection Technique and Procedures

Provide appropriate instruction for reconstitution of BETASERON and methods of self-injection, including careful review of the BETASERON Medication Guide. Instruct patients in the use of aseptic technique when administering BETASERON.

Tell patients not to re-use needles or syringes and instruct patients on safe disposal procedures. Advise patients of the importance of rotating areas of injection with each dose, to minimize the likelihood of severe injection site reactions, including necrosis or localized infection [see Medication Guide].

Hepatic Injury

Advise patients that severe hepatic injury, including hepatic failure, has been reported during the use of BETASERON.

Inform patients of symptoms of hepatic dysfunction, and instruct patients to report them immediately to their healthcare provider [see Warnings and Precautions (5.1)].

Anaphylaxis and Other Allergic Reactions

Advise patients of the symptoms of allergic reactions and anaphylaxis, and instruct patients to seek immediate medical attention if these symptoms occur [see Warnings and Precautions (5.2)].

Depression and Suicide

Advise patients that depression and suicidal ideation have been reported during the use of BETASERON. Inform patients of the symptoms of depression or suicidal ideation, and instruct patients to report them immediately to their healthcare provider [see Warnings and Precautions (5.3)].

Congestive Heart Failure

Advise patients that worsening of pre-existing congestive heart failure have been reported in patients using BETASERON.

Advise patients of symptoms of worsening cardiac condition, and instruct patients to report them immediately to their healthcare provider [see Warnings and Precautions (5.4)].

Injection Site Reactions Including Necrosis

Advise patients that injection site reactions occur in most patients treated with BETASERON, and that injection site necrosis may occur at one or multiple sites. Instruct patients to promptly report any break in the skin, which may be associated with blue-black discoloration, swelling, or drainage of fluid from the injection site, prior to continuing their BETASERON therapy [see Warnings and Precautions (5.5)].

Pulmonary Arterial Hypertension

Inform patients that PAH has occurred in patients treated with interferon beta products, including BETASERON. Instruct patients to promptly report any new symptoms such as new or increasing fatigue or shortness of breath to their healthcare provider [see Warnings and Precautions (5.8)].

5 Warnings and Precautions

5.5 Injection Site Reactions Including Necrosis (formerly Injection Site Necrosis and Reactions)

Additions and/or revisions underlined:

Injection site reactions, including injection site necrosis, can occur with the use of interferon beta products, including BETASERON. Injection site necrosis (ISN) was reported in 4% of BETASERON-treated patients in controlled clinical trials (compared to 0% on placebo) [see Adverse Reactions (6.1)]

… Approximately 69% of patients experienced injection site reactions during the first three months of treatment, compared to approximately 40% at the end of the studies. injection site abscesses and cellulitis have been reported in the postmarketing setting with use of interferon beta products including BETASERON. Some cases required treatment with hospitalization for surgical drainage and intravenous antibiotics. Periodically evaluate patient understanding and use of aseptic self-injection techniques and procedures, particularly if injection site necrosis has occurred. Patients should be advised of the importance of rotating injection sites with each dose. Whether to discontinue therapy following a single site of necrosis is dependent on the extent of necrosis. For patients who continue therapy with BETASERON after injection site necrosis has occurred, avoid administration of BETASERON into the affected area until it is fully healed. If multiple lesions occur, change injection site, or discontinue therapy until healing occurs.

Additions and/or revisions underlined:

What are the possible side effects of BETASERON?

BETASERON may cause serious side effects. Call your healthcare provider right away if you have any of the serious side effects of BETASERON, including:

  • injection site problems. Serious skin reactions can happen in some people including areas of severe damage to skin and the tissue below the skin (necrosis). These reactions can happen anywhere you inject BETASERON. Symptoms of injection site problems may include swelling, redness, or pain at the injection site, fluid drainage from the injection site, and breaks in your skin or blue-black skin discoloration. Call your healthcare provider right away if an injection site becomes swollen and painful or the area looks infected. You may have a skin infection or an area of severe skin damage (necrosis) requiring treatment by a healthcare provider.

8 Use in Specific Populations

8.1 Pregnancy

PLLR conversion; additions and/or revisions underlined:

Risk Summary

 Although there have been no well-controlled studies in pregnant women, available data, which includes prospective observational studies, have not generally indicated a drug-associated risk of major birth defects with interferon beta-1b during pregnancy. Administration of BETASERON to monkeys during gestation resulted in increased embryo-fetal death at or above exposures greater than 3 times the human therapeutic dose.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown.

Data

Human Data

The majority of the observational studies reporting on pregnancies exposed to interferon beta-1b did not identify an association between the use of interferon beta-1b during pregnancy and an increased risk of major birth defects.

Animal Data

When BETASERON (doses ranging from 0.028 to 0.42 mg/kg/day) was administered …

8.2 Lactation

PLLR conversion; additions and/or revisions underlined:

Risk Summary

There are no data on the presence of BETASERON in human milk, the effects on the breastfed infant, or the effects of the drug on milk production.

The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for BETASERON and any potential adverse effects on the breastfed child from BETASERON or from the underlying maternal condition.

5 Warnings and Precautions

Drug-induced Lupus Erythematosus

Cases of drug-induced lupus erythematosus have been reported with some interferon beta products, including BETASERON. Signs and symptoms of drug-induced lupus reported in BETASERON-treated patients have included rash, serositis, polyarthritis, nephritis, and Raynaud’s phenomenon. Cases have occurred with positive serologic testing (including positive anti-nuclear and/or anti-double-stranded DNA antibody testing). If BETASERON-treated patients develop new signs and symptoms characteristic of this syndrome, BETASERON therapy should be stopped.
