Adverse effects of ciprofloxacin
Nausea, bad taste in mouth, vomiting
Inability to concentrate, tremors, seizures
Head ache, dizziness, rashes, photophobia
Swelling of lips, tendonitis, tendon rupture
Seizures are more likely if ciprofloxacin is combined with theophylline because theophylline increases the blood levels of ciprofloxacin.
