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
infections including:
• Chest, lung or nasal infections e.g. bronchitis, pneumonia, sinusitis
• Urinary tract infections (the passage through which urine passes)
e.g. cystitis, urethritis

2. What

you need to know before you take
Do not take Vibramycin-D:

• if you are allergic to doxycycline or any other tetracycline antibiotic
or any of the other ingredients of this medicine (listed in section 6)
• if you are pregnant or trying to become pregnant
• if you are breast feeding
• if the medicine has been prescribed for a child under the age of 12
You should not use Vibramycin-D during periods of tooth development
(pregnancy, infancy or in children below 12 years old) as such use may
lead to permanent discolouration (yellow-grey-brown).

Warnings and precautions

Talk to your doctor or pharmacist before taking Vibramycin-D if any of
the following apply to you:
• you are likely to be exposed to strong sunlight or uv light (e.g. on a
sun bed). You should avoid exposure to strong sunlight while taking
this medicine as your skin may be more sensitive to sunburn than

• you have diarrhoea or usually get diarrhoea when you take
antibiotics or have suffered from problems with your stomach or
intestines. If you develop severe or prolonged or bloody diarrhoea
during or after using Vibramycin-D tell your doctor immediately
since it may be necessary to interrupt the treatment. This may be a
sign of bowel inflammation (pseudomembranous colitis) which can
occur following treatment with antibiotics.
• you are taking oral retinoids as there is a higher risk of suffering from
increased pressure in your skull (severe headache with change in
vision) when taken with Vibramycin-D.

cannot be treated with this antibiotic. Your doctor can explain the signs
and symptoms of such types of infection.
