First-line treatments
Antimicrobial or antiviral therapy
Active treatment with regular monitoring by a healthcare provider is recommended.
Targeted antibiotic therapy
Culture-directed antibiotics based on susceptibility testing for Pseudomonas aeruginosa. Oral or inhaled antibiotics may be used depending on infection severity. Treatment duration typically extends several weeks to months.
Intravenous antibiotic administration
For severe CF5 Pseudomonas infections, intravenous antibiotics are administered in hospital or home care settings. Combination therapy is often used to prevent antibiotic resistance.
Additional treatment options
Inhaled antibiotic therapy
Nebulized antibiotics such as tobramycin or aztreonam delivered directly to airways to suppress Pseudomonas growth. Often used as maintenance therapy in chronic colonization.
medicationAirway clearance techniques
Chest physiotherapy, percussion, and breathing exercises to mobilize secretions and improve lung clearance. Helps enhance antibiotic penetration and reduce bacterial burden.
