⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

6.1Clinical Trials Experience with TALICIA 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. The safety of TALICIA was assessed in adult patients who were screened and found to be positive for H. pylori infection in one active-controlled (Study 1) and one placebo-controlled (Study 2) clinical trial. Patients received TALICIA, amoxicillin and omeprazole, or placebo every eight hours for 14 consecutive days taken with food.
A total of 305 patients received TALICIA in Studies 1 and 2, 227 patients received amoxicillin and omeprazole (as omeprazole magnesium) in Study 1, and 41 patients received placebo in Study 2. These patients had a mean age of 46.4 years (range 18 to 70 years); 62.3% were female, 80.3% were white with 64.2% Hispanic or Latino. Adverse Reactions Leading to Discontinuation Treatment discontinuation due to an adverse reaction occurred in 1% (4/305) of patients receiving TALICIA, <1% (1/227) of patients receiving amoxicillin and omeprazole, and 2% (1/41) of patients receiving placebo.
Adverse reactions leading to discontinuation of TALICIA were nausea and vomiting, nausea, nasal congestion, and nasopharyngitis, in one patient each. Most Common Adverse Reactions Selected adverse reactions occurring in ≥1% of patients receiving TALICIA in Study 1 and 2 are described in Table 1 . Table 1: Selected Adverse Reactions Occurring in 1% or Greater of Patients Receiving TALICIA in Studies 1 and 2 a Headache includes: headache and migraine. b Abdominal pain includes: abdominal pain, abdominal pain upper, and abdominal pain lower. c Riboflavin was administered in Study 1 to prevent unintentional unblinding and may have contributed to under-reporting of chromaturia. d Rash includes: rash, rash maculo-papular, rash morbilliform, and urticaria. e Dyspepsia includes: dyspepsia and epigastric discomfort. f Vulvovaginal candidiasis includes: vulvovaginal candidiasis, vulvovaginal mycotic infection, fungal infection, and vaginal discharge + vulvovaginal burning sensation + vulvovaginal pruritus.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Components of TALICIA have the potential for clinically important drug interactions. See Full Prescribing Information for important drug interactions with TALICIA. ( 4 , 5.7 )
7.1Interactions with Other Drugs and Diagnostics Drug interaction studies with TALICIA have not been conducted. The drug interaction information described here is based on the prescribing information of individual TALICIA components: omeprazole, amoxicillin, and rifabutin. Rifabutin is a substrate and inducer of cytochrome P450 (CYP) 3A enzymes.
Omeprazole is a substrate and an inhibitor of CYP2C19, and a substrate of CYP3A4. Co-administration of TALICIA and other drugs that are substrates, inhibitors, or inducers of these enzymes may alter concentrations of rifabutin/omeprazole or other co-administered drugs [See Table 2 below and Clinical Pharmacology (12.3) ]. Omeprazole magnesium is a PPI.
Refer to the prescribing information of the drugs used concomitantly with TALICIA for further information on their interactions with PPIs. Table 2: Interactions with TALICIA When Co-Administered with Other Drugs and Diagnostics CYP2C19 or CYP3A4 Inducers Clinical Impact Decreased exposure of omeprazole when used concomitantly with strong inducers. Prevention or Management St.
John’s Wort, rifampin : Avoid concomitant use with TALICIA [see Warnings and Precautions (5.7) ]. Ritonavir-containing products : See prescribing information for specific drugs. CYP2C19 or CYP3A4 Inhibitors Clinical Impact Increased blood levels of omeprazole and rifabutin.
Prevention or Management Voriconazole : Concomitant use with TALICIA is contraindicated [see Contraindications (4) ] . Fluconazole, posaconazole and itraconazole : Avoid concomitant use with TALICIA. If coadministration cannot be avoided, monitor patients for rifabutin associated adverse events, and lack of anti-fungal efficacy.
CYP2C19 Substrates (e.g., Clopidogrel, citalopram, cilostazol, phenytoin, diazepam) Clinical Impact Increased plasma concentrations of CYP2C19 substrate drugs or decreased/increased plasma concentrations of its active metabolite(s) [see Clinical Pharmacology (12.3) ] . Prevention or Management Clopidogrel : Consider use of alternative anti-platelet therapy [ see Warnings and Precautions (5.7) ] . Avoid concomitant use with TALICIA.
Antiretrovirals/Protease Inhibitors Clinical Impact Antiretrovirals/protease inhibitors may increase rifabutin blood levels. The effect of PPIs (such as omeprazole in TALICIA) on antiretroviral drugs is variable. The clinical importance and the mechanisms behind these interactions are not always known.
Decreased exposure of some antiretroviral drugs (e.g., rilpivirine, atazanavir, and nelfinavir) when used concomitantly with omeprazole may reduce antiviral effect and promote the development of drug resistance [see Clinical Pharmacology (12.3) ]. Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with omeprazole may increase toxicity [see Clinical Pharmacology (12.3) ] . There are other antiretroviral drugs which do not result in clinically relevant interactions with omeprazole.
Prevention or Management Delavirdine : Combination treatment with TALICIA and delavirdine is contraindicated [see Contraindications (4) ]. Rilpivirine-containing products : Concomitant use with TALICIA is contraindicated [see Contraindications (4) ]. Avoid concomitant use of TALICIA with amprenavir, indinavir, lopinavir/ritonavir, saquinavir/ritonavir, ritonavir, tipranavir/ritonavir, fosamprenavir/ritonavir, or nelfinavir [see Warnings and Precautions (5.7) ] .
Other antiretrovirals: See prescribing information for specific antiretroviral drugs. Probenecid Clinical Impact Increased and prolonged blood levels of amoxicillin. Allopurinol Clinical Impact Increase in the incidence of rashes is reported in patients receiving both allopurinol and amoxicillin together compared to patients receiving amoxicillin alone.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS TALICIA may cause fetal harm. ( 8.1 ) Renal Impairment: Avoid use in severe renal impairment. ( 8.6 ) Hepatic Impairment: Avoid use. ( 8.7 )
8.1Pregnancy Risk Summary Based on animal reproduction studies, TALICIA may cause fetal harm when administered to pregnant women. There are no adequate and well controlled studies of amoxicillin, omeprazole, or rifabutin (used separately or together) in pregnant women. Use of TALICIA is generally not recommended for use in pregnancy.
If TALICIA is used during pregnancy, advise pregnant women of the potential risk to a fetus. Omeprazole: Available epidemiologic data do not 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 1.13 to 11 times an oral human dose of 120 mg.
Fetal malformations were 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 23 times and 14 times, respectively, of an oral human dose of 120 mg esomeprazole or omeprazole. 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 11 times an oral human dose of 120 mg esomeprazole or omeprazole.
When maternal administration was confined to gestation only, there were no effects on bone physeal morphology in the offspring at any age [see Data ] . Amoxicillin: Available data from published epidemiologic studies and pharmacovigilance case reports over several decades with amoxicillin use have not established drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes [see Data ] . No adverse developmental effects were observed in animal reproduction studies with administration of amoxicillin to pregnant mice and at doses up to 3 to 6 times an oral human dose of 3 grams.
Rifabutin: Fetal malformations were not observed in rat or rabbit reproduction studies given rifabutin at dose levels up to 200 mg/kg (6 to 13 times the recommended human dose). In rats, given rifabutin at 200 mg/kg/day (about 6 times the recommended human daily dose), there was a decrease in fetal viability. Increased skeletal anomalies were observed in rats and rabbits at 40 and 80 mg/kg/day, respectively (corresponding to approximately an equivalent dose and 5 times the recommended human daily dose); maternal toxicity was noted at 80 mg/kg in rabbits [see Data ].
The estimated background risks of major birth defects and miscarriage for the indicated population are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the US 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 Human Data Omeprazole Four published epidemiological studies compared the frequency of congenital abnormalities among infants born to women who used omeprazole during pregnancy with the frequency of abnormalities among infants of women exposed to H2-receptor antagonists or other controls. A population-based retrospective cohort epidemiological study from the Swedish Medical Birth Registry, covering approximately 99% of pregnancies, from 1995 to 99, reported on 955 infants (824 exposed during the first trimester with 39 of these exposed beyond first trimester, and 131 exposed after the first trimester) whose mothers used omeprazole during pregnancy.
The number of infants exposed in utero to omeprazole that had any malformation, low birth weight, low Apgar score, or hospitalization was similar to the number observed in this population. The number of infants born with ventricular septal defects and the number of stillborn in…
🤰 Pregnancy ▾
8.1Pregnancy Risk Summary Based on animal reproduction studies, TALICIA may cause fetal harm when administered to pregnant women. There are no adequate and well controlled studies of amoxicillin, omeprazole, or rifabutin (used separately or together) in pregnant women. Use of TALICIA is generally not recommended for use in pregnancy.
If TALICIA is used during pregnancy, advise pregnant women of the potential risk to a fetus. Omeprazole: Available epidemiologic data do not 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 1.13 to 11 times an oral human dose of 120 mg.
Fetal malformations were 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 23 times and 14 times, respectively, of an oral human dose of 120 mg esomeprazole or omeprazole. 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 11 times an oral human dose of 120 mg esomeprazole or omeprazole.
When maternal administration was confined to gestation only, there were no effects on bone physeal morphology in the offspring at any age [see Data ] . Amoxicillin: Available data from published epidemiologic studies and pharmacovigilance case reports over several decades with amoxicillin use have not established drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes [see Data ] . No adverse developmental effects were observed in animal reproduction studies with administration of amoxicillin to pregnant mice and at doses up to 3 to 6 times an oral human dose of 3 grams.
Rifabutin: Fetal malformations were not observed in rat or rabbit reproduction studies given rifabutin at dose levels up to 200 mg/kg (6 to 13 times the recommended human dose). In rats, given rifabutin at 200 mg/kg/day (about 6 times the recommended human daily dose), there was a decrease in fetal viability. Increased skeletal anomalies were observed in rats and rabbits at 40 and 80 mg/kg/day, respectively (corresponding to approximately an equivalent dose and 5 times the recommended human daily dose); maternal toxicity was noted at 80 mg/kg in rabbits [see Data ].
The estimated background risks of major birth defects and miscarriage for the indicated population are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the US 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 Human Data Omeprazole Four published epidemiological studies compared the frequency of congenital abnormalities among infants born to women who used omeprazole during pregnancy with the frequency of abnormalities among infants of women exposed to H2-receptor antagonists or other controls.

The number of infants exposed in utero to omeprazole that had any malformation, low birth weight, low Apgar score, or hospitalization was similar to the number observed in this population. The number of infants born with ventricular septal defects and the number of stillborn infants was slightly higher in the omeprazole-exposed infants than the expected number in this population.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of TALICIA in pediatric patients below the age of 18 years with H. pylori infection have not been established. Esomeprazole, an enantiomer of omeprazole, was shown to decrease body weight, body weight gain, femur weight, femur length, and overall growth in juvenile rats at oral doses about 11 to 23 times a daily human dose of 120 mg esomeprazole or omeprazole based on body surface area [see Nonclinical Toxicology (13.2) ] .
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of TALICIA did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger adult patients. Omeprazole Omeprazole was administered to over 2000 elderly individuals (≥ 65 years of age) in clinical trials in the U.S. and Europe.
There were no differences in safety and effectiveness between the elderly and younger subjects. Other reported clinical experience has not identified differences in response between the elderly and younger subjects, but greater sensitivity of some older individuals cannot be ruled out. Amoxicillin An analysis of clinical studies of amoxicillin was conducted to determine whether subjects aged 65 and older respond differently from younger subjects.
These analyses have not identified differences in responses between the elderly and younger patients, but a greater sensitivity of some older individuals cannot be ruled out. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, it may be useful to monitor renal function in elderly patients taking TALICIA.
Rifabutin Clinical studies of rifabutin did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.
🆘 Overdosage ▾
10 OVERDOSAGE TALICIA No information is available on accidental overdosage of TALICIA in humans. In case of an overdose, patients should contact a physician, poison control center, or emergency room. The available overdosage information for each of the individual components in TALICIA (omeprazole, amoxicillin and rifabutin) are summarized below: Omeprazole There have been reports of overdosage with omeprazole in humans.
Doses ranged up to 2400 mg (120 times the usual recommended clinical dose). Manifestations were variable, but included confusion, drowsiness, blurred vision, tachycardia, nausea, vomiting, diaphoresis, flushing, headache, dry mouth, and other adverse reactions similar to those seen in normal clinical experience [see Adverse Reactions (6.3) ] . Symptoms were transient, and no serious clinical outcome has been reported when omeprazole was taken alone.
No specific antidote for omeprazole overdosage is known. Omeprazole is extensively protein bound and is, therefore, not readily dialyzable. In the event of overdosage, treatment should be symptomatic and supportive.
Amoxicillin In case of overdosage, discontinue medication, treat symptomatically, and institute supportive measures as required. A prospective study of 51 pediatric patients at a poison-control center suggested that overdosages of less than 250 mg/kg of amoxicillin are not associated with significant clinical symptoms. Crystalluria, in some cases leading to renal failure, has also been reported after amoxicillin overdosage.
In case of overdosage, adequate intake and diuresis should be maintained to reduce the risk of amoxicillin crystalluria. Renal impairment appears to be reversible with cessation of drug administration. High blood concentrations may occur more readily in patients with impaired renal function because of decreased renal clearance of amoxicillin.
Amoxicillin can be removed from circulation by hemodialysis. Rifabutin No information is available on accidental overdosage of rifabutin in humans. While there is no experience in the treatment of overdose with rifabutin capsules, clinical experience with rifamycins suggests that gastric lavage to evacuate gastric contents (within a few hours of overdose), followed by instillation of an activated charcoal slurry into the stomach, may help adsorb any remaining drug from the gastrointestinal tract.
Rifabutin is 85% protein bound and distributed extensively into tissues (volume of distribution at steady state: 8 to 9 L/kg). It is not primarily excreted via the urinary route (less than 10% as unchanged drug); therefore, neither hemodialysis nor forced diuresis is expected to enhance the systemic elimination of unchanged rifabutin from the body in a patient with an overdose of rifabutin.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action TALICIA is a combination of antibacterial drugs (rifabutin, amoxicillin) and a proton pump inhibitor (omeprazole as omeprazole magnesium), an antisecretory drug [see Microbiology (12.4) ] .
12.2Pharmacodynamics After oral administration, the onset of the antisecretory effect of omeprazole occurs within one hour, with the maximum effect occurring within two hours. The antisecretory effect lasts longer than would be expected from the short (approximately one hour) plasma half-life, apparently due to prolonged binding to the parietal H+/K+ ATPase enzyme. When the drug is discontinued, secretory activity returns gradually, over 3 to 5 days.
The inhibitory effect of omeprazole on acid secretion increases with repeated daily dosing.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Hypersensitivity Reactions Advise the patient to call their healthcare provided immediately if they develop new rash, skin lesions, muscle or joint pains, swelling, severe flu-like symptoms, difficulty breathing or visual symptoms [see Warnings and Precautions (5.1) ] . Severe Cutaneous Adverse Reactions Advise patients about the signs and symptoms of serious skin manifestations. Instruct patients to stop taking TALICIA immediately and promptly report the first signs or symptoms of skin rash, mucosal lesions, or any other sign of hypersensitivity [see Warnings and Precautions (5.2) ] .
Diarrhea Counsel patients that diarrhea is a common problem caused by antibiotics, and it usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools even as late as 2 or more months after having taken their last dose of the antibiotic. Patients should contact their physician as soon as possible if they experience bloody diarrhea, persistent abdominal pain, fever, or chronic diarrhea that does not resolve [see Warnings and Precautions (5.4) ] .
Brown-Orange Discoloration Urine, feces, saliva, sputum, perspiration, tears, and skin may be colored brown-orange due to the rifabutin component of TALICIA and some of its metabolites. Soft contact lenses may be permanently stained. Advise patients to be treated with TALICIA of these possibilities and counsel the patient that these should resolve after therapy is completed.
Drug Interactions Advise patients not to take St. John’s Wort, amoxicillin or other penicillin products, rifabutin or other rifamycins, over-the counter (OTC) omeprazole or other PPIs during treatment with TALICIA. Advise patients that they should not start any new medication while taking TALICIA without first speaking with their health care provider [see Warnings and Precautions (5.7) ] .
Contraception Counsel females of reproductive potential who are taking oral or other forms of hormonal birth-control medications to use an additional non-hormonal highly effective method of contraception while taking TALICIA [see Warnings and Precautions (5.5) ] . Embryo-Fetal Toxicity Advise pregnant women and females of reproductive potential that TALICIA is not recommended during pregnancy because of the potential risk to a fetus. Advise females to inform their healthcare provider of a known or suspected pregnancy.
Cutaneous or Systemic Lupus Advise patients to report any symptoms associated with cutaneous or systemic lupus erythematosus [see Warnings and Precautions (5.8) ] . Acute Tubulointerstitial Nephritis Advise the patient or caregiver to call the patient’s healthcare provider immediately if they experience signs and/or symptoms associated with acute tubulointerstitial nephritis [see Warnings and Precautions (5.6) ] . Important Administration Instructions for TALICIA Advise patients to take four (4) TALICIA capsules three times daily (at least 4 hours apart, e.g., morning, mid-day, and evening) with food for 14 days.
They should NOT crush or chew capsules. Advise patients to swallow TALICIA with at least 8 ounces of water. Advise patients not to take TALICIA with alcohol.
Missed doses : Advise patients that if a dose is missed, and the next dose is not within 4 hours, administer as soon as possible. However, if a dose is missed and the next dose is within 4 hours, administer the missed dose as soon as possible and delay the next dose to ensure there are at least 4 hours between two doses. It is important for patients to complete the entire course of therapy.
Counsel patients that antacids may be used concomitantly with TALICIA. Counsel patients to continue the full course of TALICIA regardless of whether or not their symptoms improve. Although change in dyspepsia symptoms may occur (either improvement or worsening), these are unlikely to be related to the H. pylori infection.
