Talicia During Pregnancy and Breastfeeding

Tell your doctor if you are pregnant or plan to become pregnant before using Talicia; it may harm a fetus. Both rifabutin and amoxicillin components of Talicia interact with hormonal contraceptives resulting in lower levels of these contraceptives. Female patients taking hormonal contraceptives should use an additional non-hormonal method of contraception while taking Talicia. Amoxicillin passes into breast milk. Omeprazole may pass into breast milk. It is unknown if rifabutin passes into breast milk. Consult your doctor before breastfeeding.

Clinical 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.
