How to take oxytetracycline
Volver al contenidoBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about oxytetracycline, and will also provide you with a full list of the side-effects which you could experience from taking it.
Take oxytetracycline exactly as your doctor tells you to. If you have an infection it is likely you will be asked to take one or two tablets every six hours, and if you are being treated for acne or rosacea, the usual dose is two tablets twice daily. Your doctor or pharmacist will tell you which dose is right for you, and this information will also be printed on the label of the pack to remind you about what was said to you.
Try to take your doses around the same times of day each day. This will help you remember to take them regularly. Space out your doses evenly throughout the day.
Take the tablets when your stomach is empty. This means taking your doses one hour before you eat food, or waiting until two hours after you have eaten. It is also important that you do not drink milk within two hours (either before or after) of taking oxytetracycline. This is because both food and milk can reduce the amount of medicine absorbed by your body, making it less effective in fighting infection.
Swallow the tablets with a large drink of water. Try to avoid taking oxytetracycline just before lying down, or at bedtime.
If you forget to take a dose, take it as soon as you remember. Try to take the correct number of doses each day, but do not take two doses together to make up for a missed dose.
Obteniendo el máximo de tu tratamiento
Volver al contenidoYour course of treatment is likely to last for a week or so if you are being treated for an acute infection. If you are taking oxytetracycline for acne or rosacea, your treatment could last for several months. It is important that you keep taking the tablets until the course of treatment is finished (unless you are told to stop sooner by a doctor).
If you buy any medicines, check with a pharmacist that they are suitable to take with oxytetracycline, as a number of 'over-the-counter' remedies can interfere with it. In particular, do not take indigestion remedies, or supplements containing iron, magnesium, or zinc at the same time. This is because oxytetracycline combines with these things, which makes it less effective. If you need to take an antacid or any of the supplements mentioned, make sure you leave at least two hours before or after taking oxytetracycline before you have them.
Some people develop thrush (redness and itchiness in the mouth or vagina) after taking a course of an antibiotic. If this happens to you, speak with your doctor or pharmacist for advice.
Oxytetracycline could cause your skin to become more sensitive to sunlight than usual. Avoid strong sunlight and sunbeds until you know how your skin reacts.
This antibiotic can stop the oral typhoid vaccine from working. If you are due to have any vaccinations, make sure the person treating you knows that you are taking this medicine.
