This prescription item requires a pre approved authority from the Government in order to get this item at the quoted price. Authority prescriptions need to be applied for by the doctor writing the script and can include reasons such as increased quantities due to dosage, increased repeats, use for a pre determined specified use, or the nature of the medication itself requiring specialist interaction. In the event that an authority is not granted on the script, the price will revert to the private price quoted for that item


This item contains more than one pack of a prescription product. Before this can be dispensed the doctor has to give approval. The prescription must be written for the total quantity or the prescription must be endorsed by your doctor "Regulation 24" otherwise we will be unable to dispense the increased amount. If you proceed with the order without approval, we will only send out one pack at the single pack price and refund the difference. Eg If your prescription is written out for 30 Tablets with 5 repeats and it does not have “Regulation 24 “ written on the script, the ONLY quantity we can dispense is 30 at one time. Further dispensing of this product could only occur after an appropriate length of time - usually 21 days but depends on dosage. In this example if you would like to obtain 180 Tablets then the doctor must endorse the prescription “Regulation 24” or the quantity must be written out for 180 and not 30. NB Conditions apply on the writing of a Regulation 24 prescription. Ask your doctor or pharmacist for details.

We can no longer accept signed authority forms from your doctor as permission to dispense more than one pack. Please contact our pharmacist for more information.

If you order this item as Private, NO PBS stickers will be issued. Once any prescription order has been sent the product cannot be returned for a refund even if your doctor changes your medication or you have an adverse reaction.

General Information

Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about DORYX. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking DORYX against the benefits this medicine is expected to have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What DORYX is used for

DORYX is an antibiotic used to:
treat certain types of infections
control acne
prevent some forms of malaria, sometimes in combination with another antimalarial medicine.

This medicine belongs to a group of medicines called tetracyclines.

It works by killing or stopping the growth of bacteria which cause infections or make acne worse. It also works against parasites that cause malaria.

Tetracyclines will not work against viral infections such as colds or flu.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is not addictive.

It is available only with a doctor's prescription.

Before you take DORYX

When you must not take it

Do not take DORYX if you have an allergy to:
any medicine containing doxycycline
other tetracyclines
any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or troubled breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

Do not take this medicine if you are taking preparations containing vitamin A, isotretinoin or etretinate. Ask you doctor or pharmacist if you are not sure if you are taking one of these medicines.

Do not take this medicine if you are more than 18 weeks pregnant or are breast-feeding. As with many medicines, tetracyclines may harm your developing or breast-feeding baby. Tetracyclines may cause enamel loss and staining of your child's teeth or increase the pressure on your child's brain.

High doses of tetracyclines may also cause liver problems in pregnant women.

Do not give this medicine to children aged eight years or under unless directed by the child's doctor. DORYX like other tetracyclines, may cause enamel loss and staining in developing teeth. It may also cause increased pressure on the brain if used in infants.

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should be taking DORYX, talk to your doctor

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and DORYX may interfere with each other. These include:
preparations containing Vitamin A
some medicines used for skin problems, such as isotretinoin or etretinate
warfarin, a medicine used to prevent blood clotting
another group of antibiotics called penicillins
some medicines used in the treatment of epilepsy such as phenytoin, carbamazepine or phenobarbitone
methoxyflurane, an anaesthetic
acetazolamide, a medicine used to help the body get rid of salt and water
the contraceptive pill (birth control pill). DORYX may decrease the effectiveness of some birth control pills.

Your doctor may advise you to use an additional method of contraception while taking DORYX and for 7 days after taking DORYX. Refer to your doctor or pharmacist for advice.

These medicines may be affected by DORYX or may affect how well it works. You may need different amounts of your medicine or you may need to take different medicines.

If you are taking the following medicines, take them at least two hours before or two hours after taking DORYX:
antacids (containing aluminium, calcium or magnesium) used for indigestion
bismuth salts, found in some medicines used to treat stomach ulcers
preparations that contain iron including vitamin preparations.

These medicines may interfere with the absorption of DORYX.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take DORYX

Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the pack, ask your doctor or pharmacists for help.

How much to take

Your doctor or pharmacist will tell you how many capsules you will need to take each day.

For treating infections, the usual dose of doxycycline is two 100 mg capsules on the first day, followed by one 100 mg capsule each day from then on. For controlling acne, the usual dose is one 50 mg capsule each day. For the prevention of malaria, the usual dose is one 100 mg capsule each day, commencing two days before entering the malarious area, during the visit, and for two weeks after leaving the area. Your doctor may ask you to take a different dose, depending on your condition and how you react to the medicine. How to take it

Swallow the capsules whole with a full glass of water or milk while sitting or standing upright.

Do not lie down immediately after swallowing DORYX. It is important to stay upright, for example sitting, standing or walking around for at least half an hour after swallowing your capsule. This is to help avoid irritation to your food pipe, also called the oesophagus.

Do not chew the capsules.

When to take it

Take your medicine at about the same time each day (usually in the morning). Taking it at the same time each day will have the best effect. It will also help you to remember when to take it.

Take your medicine during or immediately after a meal. If taken on an empty stomach, it may cause stomach upset.

How long to take it

Continue taking your medicine until you finish the pack or for as long as your doctor recommends.

Keep taking this medicine for the full time of treatment even if you begin to feel better after a few days. If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.

For treating infections, DORYX is usually taken for one to two weeks.

For controlling acne, DORYX is normally taken over a period of 12 weeks.

For preventing malaria, DORYX is recommended to be taken for up to a maximum of 8 weeks. However, your doctor may prescribe DORYX for longer periods.

If you are not sure how long you should be taking this medicine, talk to your doctor.

If you forget to take it

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 it as soon as you remember, then go back to taking your medicine as you would normally.

Do not double a dose to make up for the dose you have missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much DORYX. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include an upset stomach or vomiting.

While you are taking DORYX

Things you must do

If you are taking DORYX for an infection and your symptoms do not improve within a few days or they become worse, tell your doctor.

If you get severe diarrhoea, tell your doctor or pharmacist immediately. Do this even if it occurs several weeks after DORYX has been stopped. Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care.

Do not take diarrhoea medicine without first checking with your doctor.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine

If you become pregnant while taking this medicine, tell your doctor immediately.

If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.

If you are taking iron preparations, including vitamin preparations containing iron, bismuth salts or antacid (containing aluminium, calcium or magnesium), you must take them at least two hours before or two hours after DORYX to make sure there is no problem with absorption.

Things you must not do

Do not stop taking your medicine because you are feeling better unless advised by your doctor. If you do not complete the full course, all of the bacteria causing your infection may not be killed. These bacteria may continue to grow and multiply so that your infection may not clear completely or it may return.

Do not give your medicine to anyone else, even if they have the same condition as you.

Do not use DORYX 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. If outdoors, wear protective clothing and use a 30+ sunscreen. DORYX 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 your skin does appear to be burning, see your doctor as soon as possible. You may need alternative treatment.

If you get thrush (a fungal infection which can affect the mouth and/or vagina) or any other infection while taking, or soon after stopping DORYX, tell your doctor.

Sometimes the use of this medicine allows fungi to grow as they are not killed by DORYX.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking DORYX. This medicine is effective against infections/acne and helps prevent malaria for most people, but it may have unwanted side effects in some people. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Do not be alarmed by the following lists of side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:
oral thrush - white, furry, sore tongue and mouth
vaginal thrush - sore and itchy vagina with or without discharge
rash or itching
nail changes
stomach upset or vomiting
mild irritation of the oesophagus (food-pipe)
taste loss
ringing or other persistent noise in the ears.

The above list includes the more common side effects.

Tell your doctor as soon as possible if you notice any of the following:
feeling anxious or nervous
muscle tenderness or weakness, not caused by exercise
painful swollen joints.

The above list includes serious side effects which may require medical attention.

If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
severe blisters and bleeding in the lips, eyes, mouth, nose and genitals
severe skin reactions starting as painful red areas then large blisters and ends with peeling layers of skin
difficulty in swallowing

frequent bruising
passing less urine
yellowing of the eyes or skin (jaundice)
symptoms of an allergic reaction such as shortness of breath, wheezing or troubled breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

These are serious side effects. You may need urgent medical attention or hospitalisation.

Tell your doctor if you notice anything else that is making you unwell. Other side effects not listed above may occur in some people.

After finishing it

Tell your doctor immediately if you notice any of the following side effects, particularly if they occur several weeks after stopping treatment with DORYX:
severe abdominal cramps or stomach cramps
watery and severe diarrhoea, which may also be bloody
fever in combination with one or both of the above.

These are rare but serious side effects. You may have a serious condition affecting your bowel. DORYX may cause the bacteria which are normally harmless and present in the bowel to multiply, resulting in the above symptoms. Therefore you may need urgent medical attention.

Do not take any medicine for this diarrhoea without first checking with your doctor.

Ask your doctor or pharmacist to answer any questions you may have about the side effects.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

After using DORYX


Keep your capsules in their pack until it is time to take them. If you take the capsules out of the pack they may not keep as well.

Keep your capsules in a cool dry place where the temperature stays below 25°C.

Do not store DORYX or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least one-and-a half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking this medicine or the expiry date has passed, ask your pharmacist what to do with any medicine that is left over.
