What is doxycycline used for?

Doxycycline is an antibacterial medicine. This means that it stops infections caused by germs (bacteria). It is given as a treatment for a number of different types of infection, including chest infections, some skin conditions, sexually transmitted infections, and infections in or around the mouth.

Doxycycline is also used to prevent people from getting malaria when they travel to countries where malaria occurs. Although doxycycline can only be obtained on a prescription from a doctor, it is not prescribable on the NHS to prevent malaria. This means that you will be given a private (non-NHS) prescription and you will be asked to pay the full price for the tablets/capsules if you are taking it for this reason.

Because doxycycline can be given for so many different reasons, it is important that you know why your doctor is prescribing it for you. You will be prescribed a brand of doxycycline that is appropriate for your need, as not all brands are suitable for all of these indications.

Who cannot take doxycycline?

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking doxycycline it is important that your doctor or pharmacist knows:

• Wenn Sie schwanger sind, ein Kind erwarten oder stillen.

• Wenn Sie Probleme mit der Funktionsweise Ihrer Leber haben oder wenn Sie Probleme mit der Funktionsweise Ihrer Nieren haben.

• Wenn Sie eine entzündliche Erkrankung namens systemischer Lupus erythematodes (auch Lupus oder SLE genannt) haben.

• Wenn Sie an einer Muskelschwäche leiden, die Myasthenia gravis genannt wird.

• Wenn Sie andere Arzneimittel einnehmen. Dazu gehören alle Arzneimittel, die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

How to take doxycycline

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about doxycycline, and will also provide you with a full list of the side-effects which you could experience from taking it.

• There are a number of different brands and strengths of doxycycline so it is important that you take doxycycline exactly as your doctor tells you to. It is likely you will be asked to take one dose a day, although some people will be asked to take two doses a day. If you have a problem with ulcers in your mouth, you could be asked to take four doses a day. How many doses you are asked to take will depend upon the reason for you taking it and the severity of the infection. Your doctor will tell you what dose is right for you, and this information will also be printed on the label of the pack to remind you about what the doctor said to you.

• If you have been given capsules to take, you must swallow these whole (do not open or chew them). Take them during a mealtime, with a glassful of water to make sure you have swallowed them properly. Make sure that you take them while you are sitting or standing up so that they do not get caught in your throat and cause irritation. This also means that you should not take them immediately before you go to bed.

• If you have been given dispersible tablets (Vibramycin-D®), you should stir these into a small glass of water to take them. If you are using the dispersible tablets because of recurrent mouth ulcers, rinse the solution around your mouth for 2-3 minutes, and then spit it out.

• Wenn Sie die Einnahme einer Dosis vergessen haben, holen Sie sie nach, sobald Sie sich daran erinnern. Versuchen Sie, jeden Tag die richtige Anzahl von Dosen einzunehmen, aber nehmen Sie nicht zwei Dosen gleichzeitig ein, um eine vergessene Dosis auszugleichen.

• Depending on what you are being treated for, your course of treatment could last from a week, to several months. Keep taking doxycycline until the course is finished unless you are told to stop sooner by a doctor.

How to manage doxycycline side effects

If you experience any other symptoms which you think may be due to the medicine, discuss them with your doctor or pharmacist who will be able to advise you further.

Das Beste aus Ihrer Behandlung herausholen

• Do not take indigestion remedies, or supplements containing iron, magnesium, or zinc at the same time as you take doxycycline. This is because doxycycline combines with these things, which makes it less effective in fighting infection. If you need to take an antacid or any such supplement, make sure you do not take it within two hours (either before or after) of taking doxycycline.

• Doxycycline may cause your skin to become more sensitive to sunlight than usual. Avoid strong sunlight and do not use sunbeds. Use a sun cream with a high sun protection factor on bright days, even when it is cloudy.

• Dieses Antibiotikum kann die Wirkung der Schluckimpfung gegen Typhus beeinträchtigen. Wenn Sie geimpft werden, stellen Sie sicher, dass die behandelnde Person weiß, dass Sie dieses Medikament einnehmen.

Additional information for protection against malaria

• If you are taking doxycycline to protect against malaria, you must start taking it 1-2 days before you travel. This is to ensure there is sufficient medicine in your bloodstream to give you the required protection. You should continue to take it throughout your stay and for a further four weeks after you have left the area.

• If you feel ill or develop a high temperature (fever) or flu-like symptoms while you are travelling or within one year (especially if it is within three months) of returning home, you should see your doctor straightaway. This is important, even if you have taken your antimalarial tablets correctly.

• Doxycycline will help reduce the risk of you getting malaria, but it is also important that you take the following precautions against being bitten by mosquitoes:

  • Cover up bare areas of your arms and legs with long-sleeved, loose-fitting clothing, long trousers and socks. This is especially important if you are outside after sunset, as this is when mosquitoes feed.

  • Use an effective insect repellent spray on your clothing and any area of your skin which is bare. If you are also using a sunscreen, apply the sunscreen first and the insect repellent afterwards.

  • Spray the room with an insecticide each evening a couple of hours before you go to bed. Check your sleeping areas for mosquitoes - pay particular attention to furniture and areas under your bed where insects can hide.

  • If you are sleeping in an unscreened room, use a mosquito net impregnated with an insecticide.
