• Musculoskeletal system: with prolonged use - the risk of disruption of osteogenesis;
• Skin and mucous membranes: Stevens-Johnson syndrome, toxic epidermal necrolysis;
• Other: difficulty breathing.

Prolonged use of bromine-containing drugs can lead to bromine poisoning, which is characterized by depression of the central nervous system, depressed mood, confusion, ataxia, apathy, conjunctivitis, rhinitis, tearing, acne, or purpura.
