5 Warnings and Precautions

Newly added subsection:

5.5 Severe Cutaneous Adverse Reactions

Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP) have been reported in association with the use of PPIs [see Adverse Reactions (6.2)]. Discontinue PRILOSEC at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation.

Additions and/or revisions underlined:

5.9 Hypomagnesemia and Mineral Metabolism

… Serious adverse events include tetany, arrhythmias, and seizures.

Hypomagnesemia may lead to hypocalcemia and/or hypokalemia and may exacerbate underlying hypocalcemia in at-risk patients. In most patients, treatment of hypomagnesemia required magnesium replacement and discontinuation of the PPI.

For patients expected to be on prolonged treatment or who take PPIs with medications such as digoxin or drugs that may cause hypomagnesemia (e.g., diuretics), health care professionals may consider monitoring magnesium levels prior to initiation of PPI treatment and periodically [see Adverse Reactions (6.2)].

Consider monitoring magnesium and calcium levels prior to initiation of PRILOSEC and periodically while on treatment in patients with a preexisting risk of hypocalcemia (e.g., hypoparathyroidism). Supplement with magnesium and/or calcium, as necessary. If hypocalcemia is refractory to treatment, consider discontinuing the PPI.

Approved Drug Label (PDF)

4 Contraindications

Proton pump inhibitors (PPIs), including PRILOSEC, are contraindicated in patients receiving rilpivirine-containing products.

5 Warnings and Precautions

5.1 Presence of Gastric Malignancy

In adults, symptomatic response to therapy with PRILOSEC does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in adult patients who have a suboptimal response or an early symptomatic relapse after completing treatment with a PPI. In older patients, also consider an endoscopy. (Additions and/or revisions underlined)

5.11 Interaction with Methotrexate (revised subheading)

 

5.3 Clostridium difficile-Associated Diarrhea

Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents. For more information specific to antibacterial agents (clarithromycin and amoxicillin) indicated for use in combination with PRILOSEC, refer to Warnings and Precautions sections of the corresponding prescribing information.

5.5 Cutaneous and Systemic Lupus Erythematosus (added section)

Cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) have been reported in patients taking PPIs, including PRILOSEC. These events have occurred as both new onset and an exacerbation of existing autoimmune disease. The majority of PPI-induced lupus erythematosus cases were CLE.

The most common form of CLE reported in patients treated with PPIs was subacute CLE (SCLE) and occurred within weeks to years after continuous drug therapy in patients ranging from infants to the elderly. Generally, histological findings were observed without organ involvement.

Systemic lupus erythematosus (SLE) is less commonly reported than CLE in patients receiving PPIs. PPI associated SLE is usually milder than non-drug induced SLE. Onset of SLE typically occurred within days to years after initiating treatment primarily in patients ranging from young adults to the elderly. The majority of patients presented with rash; however, arthralgia and cytopenia were also reported.

Avoid administration of PPIs for longer than medically indicated. If signs or symptoms consistent with CLE or SLE are noted in patients receiving PRILOSEC, discontinue the drug and refer the patient to the appropriate specialist for evaluation. Most patients improve with discontinuation of the PPI alone in 4 to 12 weeks. Serological testing (e.g. ANA) may be positive and elevated serological test results may take longer to resolve than clinical manifestations.

5.9 Interaction with St. John’s Wort or Rifampin (revised subheading)

 

6 Adverse Reactions

The following serious adverse reactions are described below and elsewhere in labeling:

6.1 Clinical Trials Experience with PRILOSEC Monotherapy

,,,The safety data described below reflects exposure to PRILOSEC delayed-release capsules in 3096 patients from worldwide clinical trials (465 patients from US studies and 2,631 patients from international studies). Indications clinically studied in US trials included duodenal ulcer, resistant ulcer, and Zollinger-Ellison syndrome. The international clinical trials were double blind and open-label in design. The most common adverse reactions reported (i.e., with an incidence rate greater than or equal to 2%) from PRILOSEC-treated patients enrolled in these studies included headache (7%), abdominal pain (5%), nausea (4%), diarrhea (4%), vomiting (3%), and flatulence (3%).

Additional adverse reactions that were reported with an incidence ?1% included acid regurgitation (2%), upper respiratory infection (2%), constipation (2%), dizziness (2%), rash (2%), asthenia (1%), back pain (1%), and cough (1%)…

… The clinical trial safety profile in pediatric patients who received PRILOSEC delayed-release capsules was similar to that in adult patients. Unique to the pediatric population, however, adverse reactions of the respiratory system were frequently reported in the 1 month to less than 1 year age group, the 1 to less than 2 year age group, and the 2 to 16 year age group (42%, 75%, and 19%, respectively). In addition, otitis media was frequently reported in the 1 month to less than 1 year age group (22%), fever was frequently reported in the 1 to less than 2 year age group (33% ), and accidental injuries were frequently reported in the 2 to 16 year age group (4%).

6.3 Postmarketing Experience

Body As a Whole: Hypersensitivity reactions including anaphylaxis, anaphylactic shock, angioedema, bronchospasm, interstitial nephritis, urticaria, (see also Skin below); fever; pain; fatigue; malaise; systemic lupus erythematosus.

Skin: Severe generalized skin reactions including toxic epidermal necrolysis (some fatal), Stevens-Johnson syndrome, cutaneous lupus erythematosus and erythema multiforme …

8 Use in Specific Populations

8.1 Pregnancy

(PLLR Conversion)

 

Risk Summary (additions underlined)

There are no adequate and well-controlled studies with PRILOSEC in pregnant women. Available epidemiologic data fail to demonstrate an increased risk of major congenital malformations or other adverse pregnancy outcomes with first trimester omeprazole use. Reproduction studies in rats and rabbits resulted in dose-dependent embryo-lethality at omeprazole doses that were approximately 3.4 to 34 times an oral human dose of 40 mg (based on a body surface area for a 60 kg person).

Teratogenicity was not observed in animal reproduction studies with administration of oral esomeprazole (an enantiomer of omeprazole) magnesium in rats and rabbits during organogenesis with doses about 68 times and 42 times, respectively, an oral human dose of 40 mg esomeprazole or 40 mg omeprazole (based on body surface area for a 60 kg person). However, changes in bone morphology were observed in offspring of rats dosed through most of pregnancy and lactation at doses equal to or greater than approximately 34 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole.

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

 

Animal Data

Omeprazole

Reproductive studies conducted with omeprazole in rats at oral doses up to 138 mg/kg/day (about 34 times an oral human dose of 40 mg on a body surface area basis) and in rabbits at doses up to 69.1 mg/kg/day (about 34 times an oral human dose of 40 mg on a body surface area basis) during organogenesis did not disclose any evidence for a teratogenic potential of omeprazole. In rabbits, omeprazole in a dose range of 6.9 to 69.1 mg/kg/day (about 3.4 to 34 times an oral human dose of 40 mg on a body surface area basis) administered during organogenesis produced dose-related increases in embryo- lethality, fetal resorptions, and pregnancy disruptions. In rats, dose-related embryo/fetal toxicity and postnatal developmental toxicity were observed in offspring resulting from parents treated with omeprazole at 13.8 to 138.0 mg/kg/day (about 3.4 to 34 times an oral human doses of 40 mg on a body surface area basis), administered prior to mating through the lactation period.

Esomeprazole

The data described below was generated from studies using esomeprazole, an enantiomer of omeprazole. The animal to human dose multiples are based on the assumption of equal systemic exposure to esomeprazole in humans following oral administration of either 40 mg esomeprazole or 40 mg omeprazole.

No effects on embryo-fetal development were observed in reproduction studies with esomeprazole magnesium in rats at oral doses up to 280 mg/kg/day (about 68 times an oral human dose of 40 mg on a body surface area basis) or in rabbits at oral doses up to 86 mg/kg/day (about 42 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis) administered during organogenesis.

A pre- and postnatal developmental toxicity study in rats with additional endpoints to evaluate bone development was performed with esomeprazole magnesium at oral doses of 14 to 280 mg/kg/day (about 3.4 to 68 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis). Neonatal/early postnatal (birth to weaning) survival was decreased at doses equal to or greater than 138 mg/kg/day (about 34 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis). Body weight and body weight gain were reduced and neurobehavioral or general developmental delays in the immediate post-weaning timeframe were evident at doses equal to or greater than 69 mg/kg/day (about 17 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis). In addition, decreased femur length, width and thickness of cortical bone, decreased thickness of the tibial growth plate and minimal to mild bone marrow hypocellularity were noted at doses equal to or greater than 14 mg/kg/day (about 3.4 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis). Physeal dysplasia in the femur was observed in offspring of rats treated with oral doses of esomeprazole magnesium at doses equal to or greater than 138 mg/kg/day (about 34 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis).

Effects on maternal bone were observed in pregnant and lactating rats in the pre- and postnatal toxicity study when esomeprazole magnesium was administered at oral doses of 14 to 280 mg/kg/day (about 3.4 to 68 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis). When rats were dosed from gestational day 7 through weaning on postnatal day 21, a statistically significant decrease in maternal femur weight of up to 14% (as compared to placebo treatment) was observed at doses equal to or greater than 138 mg/kg/day (about 34 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis).

8.2 Lactation

(PLLR Conversion)

Risk Summary

Limited data suggest omeprazole may be present in human milk. There is no information on the effects of omeprazole on the breastfed infant or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for PRILOSEC and any potential adverse effects on the breastfed infant from PRILOSEC or from the underlying maternal condition.

8.4 Pediatric Use

The safety and effectiveness of PRILOSEC have been established in pediatric patients 1 to 16 years for the treatment of symptomatic GERD, treatment of EE due to acid-mediated GERD, and maintenance of healing of EE due to acid- mediated GERD. Use of PRILOSEC in this age group is supported by adequate and well-controlled studies in adults and uncontrolled safety, efficacy and pharmacokinetic studies performed in pediatric and adolescent patients.

The safety and effectiveness of PRILOSEC have been established in pediatric patients 1 month to less than 1 year of age for the treatment of EE due to acid-mediated GERD and is supported by adequate and well-controlled studies in adults and safety, pharmacokinetic, and pharmacodynamic studies performed in pediatric patients.

In the pediatric population, adverse reactions of the respiratory system were frequently reported in the entire (1 month to 16 year) age group. Otitis media was frequently reported in the 1 month to less than 1 year age group, fever was frequently reported in the 1 to less than 2 year age group, and accidental injuries were frequently reported in the 2 to 16 year age group.

The safety and effectiveness of PRILOSEC have not been established in:

  • patients less than 1 year of age for:
    • Treatment of symptomatic GERD
    • Maintenance of healing of EE due to acid-mediated GERD
  • pediatric patients for:
    • Treatment of active duodenal ulcer
    • H. pylori eradication to reduce the risk of duodenal ulcer recurrence
    • Treatment of active benign gastric ulcer
    • Pathological hypersecretory conditions
  • patients less than 1 month of age for any indication.

Juvenile Animal Data

Esomeprazole, an enantiomer of omeprazole, was shown to decrease body weight, body weight gain, femur weight, femur length, and overall growth at oral doses about 34 to 68 times a daily human dose of 40 mg esomeprazole or 40 mg omeprazole based on body surface area in a juvenile rat toxicity study. The animal to human dose multiples are based on the assumption of equal systemic exposure to esomeprazole in humans following oral administration of either 40 mg esomeprazole or 40 mg omeprazole.

A 28-day toxicity study with a 14-day recovery phase was conducted in juvenile rats with esomeprazole magnesium at doses of 70 to 280 mg/kg/day (about 17 to 68 times a daily oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis). An increase in the number of deaths at the high dose of 280 mg/kg/day was observed when juvenile rats were administered esomeprazole magnesium from postnatal day 7 through postnatal day 35. In addition, doses equal to or greater than 140 mg/kg/day (about 34 times a daily oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis), produced treatment-related decreases in body weight (approximately 14%) and body weight gain, decreases in femur weight and femur length, and affected overall growth. Comparable findings described above have also been observed in this study with another esomeprazole salt, esomeprazole strontium, at equimolar doses of esomeprazole.

8.6 Hepatic Impairment

In patients with hepatic impairment (Child-Pugh Class A, B, or C) exposure to omeprazole substantially increased compared to healthy subjects. Dosage reduction of PRILOSEC to 10 mg once daily is recommended for patients with hepatic impairment for maintenance of healing of EE.

8.7 Asian Population

In studies of healthy subjects, Asians had approximately a four-fold higher exposure than Caucasians. Dosage reduction PRILOSEC to 10 mg once daily is recommended for Asian patients for maintenance of healing of EE.

MEDICATION GUIDE

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

PRILOSEC may help your acid-related symptoms, but you could still have serious stomach problems. Talk with your doctor.

PRILOSEC can cause serious side effects, including:

  • A type of kidney problem (acute interstitial nephritis). Some people who take proton pump inhibitor (PPI) medicines, including PRILOSEC, may develop a kidney problem called acute interstitial nephritis that can happen at any time during treatment with PRILOSEC. Call your doctor if you have a decrease in the amount that you urinate or if you have blood in your urine.
  • Certain types of lupus erythematosus. Lupus erythematosus is an autoimmune disorder (the body’s immune cells attack other cells or organs in the body). Some people who take PPI medicines, including PRILOSEC, may develop certain types of lupus erythematosus or have worsening of the lupus they already have. Call your doctor right away if you have new or worsening joint pain or a rash on your cheeks or arms that gets worse in the sun.

What is PRILOSEC?

PRILOSEC is a prescription medicine called a proton pump inhibitor (PPI). PRILOSEC reduces the amount of acid in your stomach.

PRILOSEC is used in adults:

  • for up to 8 weeks for the healing of duodenal ulcers. The duodenal area is the area where food passes when it leaves the stomach.

  • with certain antibiotics for 10 to 14 days to treat an infection caused by bacteria called H. pylori. If needed, your doctor may decide to prescribe another 14 to 18 days of PRILOSEC by itself after the antibiotics. Sometimes H. pylori bacteria can cause duodenal ulcers…

  • for up to 8 weeks to treat gastroesophageal reflux disease (GERD) with acid-related damage to the lining of the esophagus [called erosive esophagitis (or EE) due to acid-mediated GERD].

    For children 1 month to less than 12 months (1 year) of age, PRILOSEC is used:

  • for up to 6 weeks to treat gastroesophageal reflux disease (GERD) with acid-related damage to the lining of the esophagus [called erosive esophagitis (or EE) due to acid-mediated GERD]. It is not known if PRILOSEC is safe and effective for other uses in children 1 month to less than 12 months (1 year) of age, or in children less than 1 month of age.

    Who should not take PRILOSEC? Do not take PRILOSEC if you:

  • are taking a medicine that contains rilpivirine (EDURANT, COMPLERA) used to treat HIV-1 (Human Immunodeficiency Virus).

    What should I tell my doctor before taking PRILOSEC?

    Before taking PRILOSEC, tell your doctor about all of your medical conditions, including if you:

  • Tell your doctor about all of the medicines you take including prescription and  over-the-counter medicines, vitamins and herbal supplements. PRILOSEC may affect how other medicines work, and other medicines may affect how PRILOSEC works. Especially tell your doctor if you take an antibiotic that contains clarithromycin or amoxicillin, or if you take clopidogrel (Plavix), methotrexate (Otrxup, Rasuvo, Trexall), St. John’s Wort (Hypericum perforatum), or rifampin (Rimactane, Rifater, Rifamate).

    How should I take PRILOSEC?

  • PRILOSEC is usually taken 1 time each day. Your doctor will tell you the time of day to take PRILOSEC, based on your medical condition.

  • Antacids may be taken with PRILOSEC.

    PRILOSEC Delayed-Release Capsules

    • Swallow PRILOSEC Capsules whole. Do not chew or crush PRILOSEC Capsules.

    • If you have trouble swallowing

  • a whole capsule, you can open the capsule and take the contents in applesauce. See the “Instructions for Use” at the end of this Medication Guide for instructions on how to take PRILOSEC Capsules with applesauce.

    PRILOSEC For Delayed-Release Oral Suspension

  • PRILOSEC Suspension is mixed with water and can be taken by mouth, or given through a nasogastric tube (NG tube) or gastric tube.

  • See the “Instructions for Use” at the end of this Medication Guide for instructions on how to take PRILOSEC Suspension, and how to mix and give PRILOSEC Suspension through a nasogastric tube or gastric tube.

    If you miss a dose of PRILOSEC, take it as soon as you remember. If it is almost time for your next dose, do not take the missed dose. Take the next dose at your regular time. Do not take 2 doses at the same time to make up for the missed dose.

    If you take too much PRILOSEC, call your doctor or your poison control center at 1-800-222-1222 right away or go to the nearest emergency room.

    What are the possible side effects of PRILOSEC? PRILOSEC can cause serious side effects, including:

    See “What is the most important information I should know about PRILOSEC?”

  • Low magnesium levels in your body. This problem can be serious. Low magnesium can happen in some people who take a PPI medicine for at least 3 months.

    Your doctor may stop PRILOSEC if these symptoms happen. Tell your doctor if you have any side effect that bothers you or that does not go away. These are not all the possible side effects with PRILOSEC. For more information, ask your doctor or pharmacist. Call your doctor for medical advice about side effects.
