What is Emrosi?

From the FDA label:Minocycline hydrochloride, a semi synthetic derivative of tetracycline, is [4S-(4α,4aα,5aα,12aα)]-4,7-Bis(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,10,12,12a- tetrahydroxy-1,11-dioxo-2-naphthacenecarboxamide mono hydrochloride. Its molecular formula is C 23 H 27 N 3 O 7 •HCl with a molecular weight of 493.95. Minocycline hydrochloride has the following structure: Minocycline hydrochloride is a yellow, hygroscopic, crystalline powder. It is sparingly soluble in water, slightly soluble in ethanol (96%). A 1% w/v solution in water has pH between 3.5 and 4.5. Each EMROSI extended-release capsule contains 40 mg of minocycline (equivalent to 43.19 mg of minocycline hydrochloride) as 10 mg immediate-release and 30 mg extended-release beads and the following inactive ingredients: ethyl cellulose, hypromellose, isopropyl alcohol, microcrystalline cellulose, Opadry ® clear, polyethylene glycol 400, triethyl citrate and talc. Opadry ® clear contains: hydroxypropyl cellulose and hypromellose. Capsule shell contains gelatin, iron oxide red and titanium dioxide. White ink contains ammonia, butyl alcohol, dehydrated alcohol, isopropyl alcohol, potassium hydroxide, propylene glycol, titanium dioxide and shellac. structure

How to use

The recommended dosage of EMROSI is one capsule taken orally, once daily. Higher doses have not shown to be of additional benefit in the treatment of rosacea. EMROSI may be taken with or without food [see Clinical Pharmacology (12.3) ] . Ingestion of food along with EMROSI may help to reduce the risk of esophageal irritation and ulceration. Swallow the capsule whole. Do not crush or chew the extended-release capsule. The recommended dosage of EMROSI is 40 mg orally, once daily. ( 2 )

Side effects

The following clinically significant adverse reactions are described elsewhere in the labeling: Serious Skin/Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Clostridioides difficile -Associated Diarrhea (Antibiotic-Associated Colitis) [see Warnings and Precautions (5.4) ] Hepatotoxicity [see Warnings and Precautions (5.5) ] Central Nervous System Effects [see Warnings and Precautions (5.6) ] Idiopathic Intracranial Hypertension [see Warnings and Precautions (5.7) ] The most commonly observed adverse reaction (incidence ≥1%) is dyspepsia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Journey Medical Corporation at 1-855-531-1859 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. In two clinical trials, MVOR-1 and MVOR-2, a total of 638 adult subjects were analyzed under the safety population with 243 subjects in EMROSI group, 237 subjects in doxycycline (40 mg) group and 158 subjects in placebo group [see Clinical Studies (14) ]. The most common adverse reaction reported by ≥1% of subjects treated with EMROSI and more frequently than in subjects receiving placebo…

Warnings

Important safety information

Serious Skin/Hypersensitivity Reactions: Minocycline has been associated with anaphylaxis, serious skin reactions, erythema multiforme, and drug rash with eosinophilia and systemic symptoms (DRESS) syndrome. Discontinue EMROSI immediately if symptoms occur. ( 5.1 ) Tooth Discoloration and Enamel Hypoplasia: The use of EMROSI 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). ( 5.2 ) Inhibition of Bone Growth: Use during the second and third trimesters of pregnancy, infancy, and childhood up to the age of 8 years may cause reversible inhibition of bone growth. ( 5.3 ) Clostridioides difficile -Associated Diarrhea (Antibiotic-Associated Colitis): Discontinue if Clostridioides difficile -associated diarrhea (antibiotic-associated colitis) occurs. ( 5.4 ) Hepatotoxicity: Discontinue EMROSI if liver injury is suspected. ( 5.5 ) Central Nervous System Effects: May cause central nervous system side effects including light-headedness, dizziness, or vertigo. ( 5.6 ) Idiopathic Intracranial Hypertension: May cause idiopathic intracranial hypertension in adults and adolescents. Discontinue EMROSI if symptoms occur. ( 5.7 ) Autoimmune Syndromes: Minocycline has been associated with autoimmune syndromes; discontinue EMROSI immediately if symptoms occur. ( 5.8 ) Metabolic Effects: If renal impairment exists, monitor serum levels of EMROSI during treatment, discontinue EMROSI if necessary. ( 5.9 ) 5.1 Hypersensitivity Reaction and Serious Skin Reactions Cases of anaphylaxis, serious skin reactions (e.g., Stevens-Johnson syndrome), erythema multiforme, and drug rash with eosinophilia and systemic symptoms (DRESS) syndrome have been reported postmarketing with minocycline use in patients with acne. DRESS syndrome consists of cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, and one or more of the following visceral complications such as: hepatitis, pneumonitis, nephritis, myocarditis, and pericarditis. Fever and lymphadenopathy may be present. In some cases, death has been reported. If this syndrome is recognized, discontinue EMROSI immediately. 5.2 Tooth Discoloration and Enamel Hypoplasia The use of tetracycline class drugs, including EMROSI 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). Permanent discoloration of the teeth is more common during long-term use of tetracycline-class drugs but has been observed following repeated short-term courses. Enamel hypoplasia has also been reported. Use of EMROSI is not recommended during tooth development. Advise the patient of the potential risk to the fetus if EMROSI is used during the second or third trimester of pregnancy [see Use in Specific Populations (8.1 , 8.4 )]. 5.3 Inhibition of Bone Growth The use of tetracycline-class drugs, including EMROSI, during the second and third trimesters of pregnancy, infancy, and childhood up to the age of 8 years may cause reversible inhibition of bone growth. All tetracyclines, including EMROSI, 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. Advise the patient of the potential risk to the fetus if EMROSI is used during the second or third trimester of pregnancy [see Use in Specific Populations (8.1 , 8.4 )]. 5.4 Clostridioides difficile -Associated Diarrhea (Antibiotic-Associated Colitis) Clostridium difficile associated diarrhea (CDAD) has been reported with nearly all antibacterial agents, including minocycline, and may range in severity from mild diarrhea to fatal colitis. 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, discontinue EMROSI. 5.5 Hepatotoxicity Postmarketing cases of serious liver injury, including irreversible drug-induced hepatitis and fulminant hepatic failure (sometimes fatal) have been reported with minocycline use in the treatment of acne. Discontinue EMROSI if liver injury is suspected. 5.6 Central Nervous System Effects Central nervous system side effects including light-headedness, dizziness or vertigo have been reported with minocycline therapy. Caution patients who experience these symptoms about driving vehicles or using hazardous machinery while on EMROSI. These symptoms may disappear during therapy and usually rapidly disappear when the drug is discontinued. 5.7 Idiopathic Intracranial Hypertension Idiopathic Intracranial hypertension has been associated with the use of tetracyclines. Clinical manifestations of idiopathic intracranial hypertension include headache, blurred vision, diplopia, and vision loss; papilledema can be found on fundoscopy. Women of childbearing age who are overweight or have a history of idiopathic intracranial hypertension are at a greater risk for developing idiopathic intracranial hypertension. Avoid concomitant use of isotretinoin and EMROSI because isotretinoin, a systemic retinoid, is also known to cause idiopathic intracranial hypertension. Permanent visual loss may exist, even after the medication is discontinued. If visual disturbance occurs during treatment, prompt ophthalmologic evaluation is warranted. Because intracranial pressure can remain elevated for weeks after drug cessation, monitor patients until they stabilize. 5.8 Autoimmune Syndromes Tetracyclines have been associated with the development of autoimmune syndromes. The long-term use of minocycline in the treatment of acne has been associated with drug-induced lupus-like syndrome, autoimmune hepatitis and vasculitis. Sporadic cases of serum sickness have presented shortly after minocycline use. Symptoms may be manifested by fever, rash, arthralgia, and malaise. Evaluate symptomatic patients. If symptoms occur, immediately discontinue EMROSI. 5.9 Metabolic Effects The anti-anabolic action of the tetracyclines, including EMROSI, may cause an increase in blood urea nitrogen (BUN). In patients with significantly impaired renal function, higher serum levels of EMROSI may lead to azotemia, hyperphosphatemia, and acidosis. If renal impairment exists, monitor serum levels of EMROSI during treatment, and discontinue EMROSI if necessary. 5.10 Photosensitivity Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines, including minocycline. Advise patients to minimize or avoid exposure to natural or artificial sunlight (tanning beds or UVA/B treatment) while using EMROSI. Instruct patients to use sunscreen products and wear protective apparel (e.g., hat) when exposure to sun cannot be avoided. 5.11 Tissue Hyperpigmentation Tetracycline-class antibiotics are known to cause hyperpigmentation. EMROSI may induce hyperpigmentation in many organs, including nails, bone, skin, eyes, thyroid, visceral tissue, oral cavity (teeth, mucosa, alveolar bone), sclerae and heart valves. Skin and oral pigmentation has been reported to occur independently of time or amount of drug administration, whereas other tissue pigmentation has been reported to occur upon prolonged administration. Skin pigmentation includes diffuse pigmentation as well as over sites of scars or injury. 5.12 Development of Drug-Resistant Bacteria Bacterial resistance to…

Who should not take Emrosi

Interactions

Patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. ( 7.1 ) 7.1 Anticoagulants Because tetracyclines have been shown to decrease plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. 7.2 Penicillin Because bacteriostatic drugs may interfere with the bactericidal action of penicillin, avoid giving EMROSI in conjunction with penicillin. 7.3 Antacids and Iron Preparations Absorption of tetracyclines is impaired by antacids containing aluminum, calcium or magnesium and iron-containing preparations. 7.4 Drug/Laboratory Test Interactions False elevations of urinary catecholamine levels may occur due to interference with the fluorescence test.

How long does Minocycline Hydrochloride stay in your body?

The elimination half-life of minocycline hydrochloride is about 15.5 hours (range 11 to 22 hours) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. Per the oral capsule label, the serum half-life in normal volunteers ranged from 11.1 to 22.1 hours, averaging 15.5 hours. Kidney and liver function change it: in renal impairment the half-life is markedly prolonged (18 to 69 hours), while in hepatic impairment it ran 11 to 16 hours. Minocycline is not a prodrug and has no active metabolite that outlasts the parent. Elimination half-life is not the same as a drug-test detection window.

This is general information, not medical advice. It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.

Frequently asked questions

What does Emrosi treat?
Emrosi (Minocycline Hydrochloride) may be used to treat acne vulgaris, anthrax, borrelia infections, chancroid, cholera, escherichia coli infections, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Emrosi work?
Emrosi is a tetracycline-class drug. Tetracyclines slip inside bacteria and bind to the 30S part of their ribosome, the cell's protein-building machine. This blocks the bacteria from adding new amino acids, so they can't make the proteins they need to grow or multiply, letting the immune system clear the infection.
How much does Emrosi cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $11.02 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
