1. WHAT VIBRAMYCIN-D IS AND WHAT IS IT USED FOR
Vibramycin-D contains the active substance doxycycline as doxycycline monohydrate. Vibramycin-D is an
antibiotic belonging to a group of medicines called tetracyclines. It is used to treat many different types of
• Chest, lung or nasal infections e.g. bronchitis, pneumonia, sinusitis
• Urinary tract infections (the passage through which urine passes) e.g. cystitis, urethritis.
• Acne (a skin condition)
• Eye infections
• Sexually transmitted diseases e.g. gonorrhoea, syphilis, chlamydia
• Fevers associated with louse or tick bites
• Malaria, when chloroquine is not effective
Vibramycin-D is also used to prevent certain infections developing, these are scrub typhus (a disease
carried by small insects) travellers’ diarrhoea, malaria and leptospirosis (a bacterial infection).
Your doctor may want you to take Vibramycin-D to treat another infection not listed above. You may also be
prescribed an additional medicine to take with Vibramycin-D to treat your infection. You must talk to your
doctor if you do not feel better or if you feel worse.
