What Doxycycline AN is used for
Doxycycline AN is an antibiotic used to
- Treat certain infections
- Control acne
- Prevent malaria
Doxycyline AN tablets belong to a class of medicines called tetracyclines.
These medicines work by killing or stopping the growth of bacteria which cause infections or make acne worse. They also work against parasites which cause malaria.
Tetracyclines will not work against viral infections such as colds or the ‘flu’.
Your doctor, however, may prescribe Doxycycline AN for another purpose. Ask your doctor if you have any questions about why Doxycycline AN has been prescribed for you.
This medicine is only available with a doctor’s prescription.
There is no evidence that Doxycycline AN is addictive.
Before You Take Doxycycline AN

Do not take Doxycycline AN if:
- You have ever had an allergic reaction to
- Medicines containing doxycycline, or doxycycline hydrochloride

Some of the symptoms of an allergic reaction to tetracyclines may include: rash, itching or hives of the skin, swelling of the face, lops and tongue or other parts of the body, shortness of breath, wheezing or troubled breathing
- You are taking preparations containing Vitamin A, isotretinoin or etretinate
Ask your doctor or pharmacist if you are not sure if you are taking one of these medicines
- You are in the second or third trimester of pregnancy or breastfeeding
As with many medicines, tetracyclines can harm the developing or breastfeeding baby. This may include enamel loss and staining of the child’s teeth and increase the pressure on your child’s brain.
High doses of tetracyclines may also cause liver problems in pregnant women.
If you are not sure whether you should be taking Doxycycline AN, talk to your doctor.
Do not take Doxycycline AN if:
- The expiry date on the pack has passed
If you take this medicine after the expiry date has passed it may have no effect at all, or worse, an entirely unexpected effect.
- The packaging is torn or shows signs of tampering.
Do not give Doxycycline AN to children of eight years and under unless directed by the child’s doctor. Doxycycline AN like all other tetracyclines may cause enamel loss and staining in developing teeth.
Before you start to take Doxycycline AN

Some medicines may interfere with the absorption of Doxycycline AN tablets. These include:
- iron preparations, including vitamin preparations which contain iron
- antacids used for indigestion containing aluminium, calcium or magnesium
- do not drink alcohol or take any of these medicines if you are taking Doxycycline AN tablets.
You can still take these medicines while you are taking Doxycycline AN. However, you must take your Doxycycline AN Tablets at least two hours before or two hours after taking any of these medicines to make sure that there is no problem with absorption.

Depending on your condition, your doctor will tell you how much Doxycycline AN to take. Follow all instructions carefully.
How to take it
Swallow the prescribed dose of Doxycycline AN whole with a full glass of water or milk while standing upright. Do not lie down immediately after swallowing Doxycycline AN.

Late evening ingestion of the tablet should be avoided.

Doxycycline AN tablets should be taken as prescribed by your doctor. For severe acne the tablets may be taken up to a maximum of 12 weeks.
For treating infections
Doxycycline AN tablets are usually taken for one to two weeks. Do not stop taking Doxycycline AN because you are feeling better. If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.
For preventing malaria,
Doxycycline AN tablets are normally recommended to be taken for up to a maximum of eight weeks.
However, your doctor may prescribe Doxycycline AN tablets for longer periods. Check with your doctor if you are not sure how long you should be taking it.
Continue taking Doxycycline AN tablets until you finish the pack or until your doctor recommends.
Follow all directions given to you by your doctor and pharmacist carefully.
If you forget to take Doxycycline AN
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Doxycycline AN. Do this even if there are no signs of discomfort or poisoning.

While you are taking Doxycycline AN
Things you must do
If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.
If you get severe diarrhoea tell your doctor, pharmacist or nurse immediately. Do this even if this occurs several weeks after you have stopped taking Doxycycline AN. Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any diarrhoea medicine without first checking with your doctor.
If you get a sore white mouth or tongue while taking or soon after stopping Doxycycline AN tell your doctor. Also tell your doctor if you get vaginal itching or discharge. This may mean you have a fungal infection called thrush.
Sometimes the use of Doxycycline AN allows fungi to grow and the above symptoms to occur. Doxycycline AN do not work against fungi.
If you become pregnant while you are taking Doxycycline AN, tell your doctor.
If you are about to start taking a new medicine tell your doctor and pharmacist that you are taking Doxycycline AN.
Things you must not do
Do not stop taking your tablets because you are feeling better, unless advised to do so by your doctor. If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.
Do not give Doxycycline AN to anyone else even if they have the same condition as you.
Do not use Doxycycline AN to treat any other complaints unless your doctor tells you to.
Things to be careful of
Protect your skin when you are in the sun, especially between 10am and 3pm. Doxycycline may cause your skin to be much more sensitive to sunlight than it is normally.
Exposure to sunlight may cause a skin rash, itching, redness, or a severe sunburn. If outdoors, wear protective clothing and use a 30+ sunscreen. If your skin does appear to be burning, stop taking doxycycline and tell your doctor.
Be careful of driving or operating machinery until you know how Doxycycline AN affects you. Doxycycline AN does not normally cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines Doxycycline tablets may cause tiredness in some people.
Tell your doctor or pharmacist as soon as possible if you have any problems while you are taking Doxycycline AN, even if you do not think that the problems are connected with the medicine or are not listed in this leaflet.
Like all medicines, Doxycycline AN can cause side effects. If they occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.
