How does Minosil work?
Minosil works by interfering with the ability of bacteria to produce proteins that are essential to them. Without these proteins the bacteria cannot grow, multiply and increase in numbers. Minosil therefore stops the spread of the infection and the remaining bacteria are killed by the immune system or eventually die.
Minosil is active against the bacteria associated with acne, Propionebacterium acnes. This is a common type of bacteria that feeds on sebum produced by the sebaceous glands in the skin. It produces waste products and fatty acids that irritate the sebaceous glands, making them inflamed and causing spots. By controlling bacterial numbers, minocycline brings the inflammation of the sebaceous glands under control and allows the skin to heal.
What is it used for?
How do I take it?
- Minosil capsules are modified-release capsules that are taken once a day. The capsules should be swallowed whole and not opened, crushed or chewed, as this would damage the modified release action. They should be taken at the same time each day.
- The capsules should be swallowed whole with plenty of water while you are sitting or standing. This is to avoid the medicine irritating the throat. Avoid taking a dose just before going to bed.
- Minosil can be taken either with or without food.
- Do not take indigestion remedies or medicines containing aluminium, calcium, iron, magnesium or zinc at the same time of day as this medicine. These medicines can reduce the absorption of Minosil from the gut.
- Unless your doctor tells you otherwise, it is important that you finish the prescribed course of this antibiotic medicine, even if you feel better or it seems the infection has cleared up. Stopping the course early increases the chance that the infection will come back and that the bacteria will grow resistant to the antibiotic.

Pregnancy and breastfeeding

How can Minox affect other medicines?
It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to ensure that the combination is safe.
The following medicines may reduce the absorption of Minosil from the gut, which may make it less effective. If you are taking medicines containing any of the following ingredients they should be taken at least three hours before or after your Minosil dose:
- aluminium salts
- antacids for heartburn and indigestion containing aluminium, bismuth, calcium or magnesium
- calcium supplements
- iron preparations, eg ferrous sulphate (minocycline also reduces the absorption of iron from the gut)
- magnesium salts
- quinapril tablets that contain magnesium carbonate, eg Accupro brand
- ranitidine bismuth citrate
- tripotassium dicitrato-bismuthate
- zinc salts (minocycline also reduces the absorption of zinc from the gut)
- Videx chewable/dispersible tablets (didanosine) - these also contain an antacid.
Use in the elderly:
Clinical studies of Minosil did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently than younger subjects. Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.
Use in children:
The use of tetracyclines during tooth development in children under the age of 12 years may cause permanent discolouration. Enamel hypoplasia has also been reported.
If you have any more questions please ask your Pharmacist.
