SEYSARA is contraindicated in persons who have shown hypersensitivity to any of the tetracyclines. SEYSARA is contraindicated in persons who have shown hypersensitivity to any of the tetracyclines. ( 4 )

The use of SEYSARA during tooth development (second and third trimesters of pregnancy, infancy, and childhood up to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown). ( 5.1 ) If Clostridium difficile Associated Diarrhea (antibiotic associated colitis) occurs, discontinue SEYSARA. ( 5.2 ) Central nervous system side effects, including light-headedness, dizziness or vertigo, have been reported with tetracycline use. Patients who experience these symptoms should be cautioned about driving vehicles or using hazardous machinery. These symptoms may disappear during therapy and may disappear when the drug is discontinued. ( 5.3 ) SEYSARA may cause intracranial hypertension. Discontinue SEYSARA if symptoms occur. ( 5.4 ) Photosensitivity can occur with SEYSARA. Patients should minimize or avoid exposure to natural or artificial sunlight. ( 5.5 )

5.1 Teratogenic Effects SEYSARA, like other tetracyclines, can cause fetal harm when administered to a pregnant woman. If SEYSARA is used during pregnancy or if the patient becomes pregnant while taking SEYSARA, the patient should be informed of the potential hazard to the fetus and treatment should be stopped immediately. The use of drugs of the tetracycline-class during tooth development (second and third trimesters of pregnancy, infancy, and childhood up to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown). This adverse reaction is more common during long-term use of these drugs, but has been observed following repeated short-term courses. Enamel hypoplasia has also been reported. All tetracyclines form a stable calcium complex in any bone-forming tissue. A decrease in fibula growth rate has been observed in premature human infants given oral tetracycline in doses of 25 mg/kg every 6 hours. This reaction was shown to be reversible when the drug was discontinued. Results of animal studies indicate that tetracyclines cross the placenta, are found in fetal tissues, and can cause retardation of skeletal development on the developing fetus. Evidence of embryotoxicity has been noted in animals treated with SEYSARA during pregnancy in association with maternal toxicity [see Use in Specific Populations ( 8.1 )] .

5.2 Clostridium difficile Associated Diarrhea (Antibiotic Associated Colitis) Clostridium difficile associated diarrhea (CDAD) has been reported with nearly all antibacterial agents, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to potential overgrowth of C. difficile. C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile should be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated.

5.3 Central Nervous System Effects Central nervous system side effects including light-headedness, dizziness or vertigo have been reported with tetracycline use. Patients who experience these symptoms should be cautioned about driving vehicles or using hazardous machinery. These symptoms may disappear during therapy and may disappear when the drug is discontinued.

5.4 Intracranial Hypertension Intracranial hypertension in adults and adolescents has been associated with the use of tetracyclines. Clinical manifestations include headache, blurred vision and papilledema. Although signs and symptoms of intracranial hypertension resolve after discontinuation of treatment, the possibility for sequelae such as visual loss that may be permanent or severe exists. Women of childbearing age who are overweight have a greater risk for developing intracranial hypertension. Patients should be questioned for visual disturbances prior to initiation of treatment with tetracyclines. Concomitant use of isotretinoin and SEYSARA should be avoided because isotretinoin, a systemic retinoid, is also known to cause intracranial hypertension [see Drug Interactions ( 7.1 )] . If visual disturbance occurs during treatment, patients should be checked for papilledema.

5.5 Photosensitivity Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines. Patients should minimize or avoid exposure to natural or artificial sunlight (tanning beds or UVA/B treatment) while using SEYSARA. If patients need to be outdoors while using SEYSARA, they should wear loose-fitting clothes that protect skin from sun exposure and discuss other sun protection measures with their physician.

5.6 Development of Drug Resistant Bacteria Bacterial resistance to tetracyclines may develop in patients using SEYSARA. Because of the potential for drug-resistant bacteria to develop during the use of SEYSARA, it should only be used as indicated.

5.7 Superinfection/Potential for Microbial Overgrowth As with other antibiotic preparations, use of SEYSARA may result in overgrowth of nonsusceptible organisms, including fungi. If superinfection occurs, SEYSARA should be discontinued and appropriate therapy instituted.

Most common adverse reaction (incidence ≥ 1%) is nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Almirall at 1-866-665-2782 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. A total of 1064 subjects and 1069 subjects with moderate to severe acne vulgaris were treated with SEYSARA and placebo, respectively, for 12 weeks in 3 controlled clinical trials. The only adverse drug reaction that was reported in at least 1% of subjects was nausea, SEYSARA (3.1%) versus placebo (2.0%). The following additional adverse drug reactions occurred in less than 1% of female SEYSARA subjects: vulvovaginal mycotic infection (0.8%) and vulvovaginal candidiasis (0.6%).

Oral retinoids: avoid coadministration. ( 5.4 , 7.1 ) Antacids and iron preparations: separate dosing of SEYSARA. ( 7.1 ) Penicillin: avoid coadministration. ( 7.2 ) Anticoagulants: decrease anticoagulant dosage as appropriate. ( 7.2 ) P-glycoprotein substrates: monitor for toxicities of drugs that may require dosage reduction. ( 7.2 )

7.1 Effect of Other Drugs on SEYSARA Oral Retinoids Tetracyclines may cause increased intracranial pressure as do oral retinoids, including isotretinoin and acitretin [see Warnings and Precautions ( 5.4 )] . Avoid coadministration of SEYSARA with oral retinoids. Antacids and Iron Preparations Coadministration with antacids containing aluminum, calcium or magnesium, bismuth subsalicylate, and iron-containing preparations may impair absorption of SEYSARA, similar to other tetracyclines, which may decrease its efficacy. Separate dosing of SEYSARA from antacids containing aluminum, calcium or magnesium, bismuth subsalicylate, and iron-containing preparations.

7.2 Effect of SEYSARA on Other Drugs Penicillin Similar to other tetracyclines, SEYSARA may interfere with the bactericidal action of penicillin. Avoid coadministration of SEYSARA with penicillin. Anticoagulants Similar to other tetracyclines, SEYSARA may depress plasma prothrombin activity, which may increase the risk of bleeding in patients who are on anticoagulant therapy. Decrease anticoagulant dosage when coadministered with SEYSARA as appropriate. P-Glycoprotein (P-gp) Substrates Concomitant use of SEYSARA may increase concentrations of concomitantly administered P-gp substrates (e.g. digoxin). Monitor for toxicities of drugs that are P-gp substrates and may require dosage reduction when given concurrently with SEYSARA [see Clinical Pharmacology ( 12.3 )] . Oral Hormonal Contraceptives There is no clinically significant effect of SEYSARA on the efficacy of oral contraceptives containing ethinyl estradiol and norethindrone acetate [see Clinical Pharmacology ( 12.3 )] .

Sarecycline, like other tetracycline-class drugs, can cause fetal harm when administered to a pregnant woman. ( 5.1 , 8.1 ) The use of drugs of the tetracycline class during tooth development may cause permanent discoloration of teeth. ( 5.1 , 8.4 ) Lactation: Breastfeeding is not recommended. ( 8.2 )

8.1 Pregnancy Risk Summary SEYSARA, like tetracycline class drugs, may cause fetal harm, permanent discoloration of teeth, and reversible inhibition of bone growth when administered during pregnancy [see Warnings and Precautions ( 5.1 ) and Use in Specific Populations ( 8.4 )] . The limited available human data are not sufficient to inform a drug-associated risk for birth defects or miscarriage. Tetracyclines are known to cross the placental barrier; therefore, SEYSARA may be transmitted from the mother to the developing fetus. In animal reproduction studies, sarecycline induced skeletal malformations in fetuses when orally administered to pregnant rats during the period of organogenesis at a dose 1.4 times the maximum recommended human dose (MRHD) of 150 mg/day (based on AUC comparison). When dosing with sarecycline continued through the period of lactation, decreases in offspring survival, offspring body weight, and implantation sites and viable embryos in offspring females occurred at a dose 3 times the MRHD (based on AUC comparison) [see Data ] . The potential risk to the fetus outweighs the potential benefit to the mother from SEYSARA use during pregnancy; therefore, pregnant patients should discontinue SEYSARA as soon as pregnancy is recognized. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The background risk of major birth defects and miscarriage for the indicated population is 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. Data Animal Data In an embryofetal developmental study in rats, sarecycline was administered to pregnant rats at oral doses up to 500 mg/kg/day during the period of organogenesis. Decreases in maternal body weight, fetal body weight and litter size and increases in the number of resorption and postimplantation loss occurred at 500 mg/kg/day (7 times the MRHD based on AUC comparison). Skeletal malformations (bent forelimb, hindlimb, and scapula) occurred at all dose levels (≥ 50 mg/kg/day, 1.4 times the MRHD based on AUC comparison). In an embryofetal developmental study in rabbits, sarecycline was administered to pregnant rabbits at oral doses up to 150 mg/kg/day during the period of organogenesis. Excessive maternal toxicity (mortality/moribundity/abortion) occurred at 150 mg/kg/day (5 times the MRHD based on AUC comparison) and this dose group was terminated early. Maternal moribundity also occurred at 100 mg/kg/day (0.6 times the MRHD based on AUC comparison). No significant embryofetal toxicity or malformations were observed at doses up to 100 mg/kg/day (0.6 times the MRHD based on AUC comparison). In a pre- and post-natal developmental study in rats, sarecycline was administered to maternal rats at oral doses up to 400 mg/kg/day during the period of organogenesis through lactation. Excessive litter toxicity (litter loss and stillbirth) occurred at 400 mg/kg/day (8 times the MRHD based on AUC comparison), which led to early termination of dams at parturition. Decreases in body weight and food consumption of dams during the lactation period occurred at 150 mg/kg/day (3 times the MRHD based on AUC comparison). Decreases in offspring survival and offspring body weight during the preweaning and growth period, and decreases in implantation sites and viable embryos in female offspring occurred at 150 mg/kg/day (3 times the MRHD based on AUC comparison). No significant maternal or developmental toxicity was observed at 50 mg/kg/day (1.4 times the MRHD based on AUC comparison).

8.2 Lactation Risk Summary Tetracyclines are excreted in human milk. Because of the potential for serious adverse reactions on bone and tooth development in nursing infants from tetracycline-class antibiotics, advise a woman that breastfeeding is not recommended with SEYSARA therapy [see Warnings and Precautions ( 5.1 )] .

8.3 Females and Males of Reproductive Potential Infertility Avoid using SEYSARA in males who are attempting to conceive a child. In a fertility study in rats, sarecycline adversely affected spermatogenesis when orally administered to male rats at a dose 8 times the MRHD (based on AUC comparison) [see Nonclinical Toxicology ( 13.1 )] .

8.4 Pediatric Use The safety and effectiveness of SEYSARA have been established in pediatric patients 9 years of age and older for the treatment of moderate to severe inflammatory lesions of non-nodular acne vulgaris [see Pharmacokinetics ( 12.3 ) and Clinical Studies ( 14 )] . Safety and effectiveness of SEYSARA in pediatric patients below the age of 9 years has not been established. Use of tetracycline-class antibiotics below the age of 8 is not recommended due to the potential for tooth discoloration [see Warnings and Precautions ( 5.1 )] .

8.5 Geriatric Use Clinical studies of SEYSARA did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Sarecycline is an aminomethylcycline within the tetracycline class of drugs. [see CLINICAL PHARMACOLOGY ( 12.4 )] . The mechanism of action of SEYSARA in treating the inflammatory lesions of non-nodular acne vulgaris is not known.
