Tobi is prescribed for the management of chronic Pseudomonas aeruginosa infections in the lungs of cystic fibrosis patients. It is not used for treating other bacterial infections or conditions unrelated to cystic fibrosis.
Tobramycin, the active ingredient, is an aminoglycoside antibiotic that works by inhibiting bacterial protein synthesis. When inhaled, it is delivered directly to the airways where it accumulates in bacterial cells and disrupts their ability to produce proteins essential for survival, effectively killing or stopping the growth of Pseudomonas aeruginosa.
Tobi should be used exactly as prescribed by a healthcare provider. Common side effects may include voice changes, sore throat, and cough. Patients with kidney problems, hearing problems, or neuromuscular diseases should inform their doctor before use. Bronchospasm can occur in some patients; a test dose may be recommended initially. Tobi capsules are for inhalation use only and should not be injected or swallowed.
