Akamin is an antibiotic that belongs to a group of medicines called tetracyclines. These medicines work by stopping the growth of bacteria which cause infections or make acne worse.
Akamin will not work against infections caused by viruses, such as colds or flu.

Your doctor may have prescribed Akamin for another reason.
Akamin is available only with a doctor’s prescription.
There is no evidence that Akamin is addictive.

Medicines which interfere with the absorption of Akamin include:
antacids (containing aluminium, calcium or magnesium) used for indigestion
preparations containing iron including vitamin supplements.
You can still take these medicines while you are taking Akamin. However, you must take Akamin at least 2 hours before or 2 hours after taking any of these medicines to make sure there is no problem with absorption.

How to take Akamin

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 bottle, ask your doctor or pharmacist.

How much to take

For treating infections, the usual dose for adults is 200 mg initially, followed by 100 mg every 12 hours.
For controlling acne, the usual dose is 50 mg twice a day.
However, depending on your condition and your response to this medicine, your doctor may ask you to take a different dose.
People with kidney problems may require smaller doses.

How to take it

Swallow the tablets or capsules whole with a full glass of water or milk while sitting or standing upright.
Stay upright for at least 30 minutes. Do not lie down immediately after taking Akamin.
This is to help avoid irritation to your oesophagus (food pipe), which you may feel as heartburn or indigestion.

When to take it

Take Akamin during or immediately after a meal.
This will reduce the chances of stomach upset.
Take Akamin at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

How long to take it for

Keep taking Akamin until you finish the tablets or capsules, or for as long as your doctor recommends.
For infections, your doctor will tell you when to stop taking Akamin, as the length of treatment varies depending on the condition you have. This is usually 24 to 48 hours after the fever and signs of infection have gone.
Do not stop taking Akamin, even if you feel better after a few days, unless advised by your doctor.
Your infection may not clear completely if you stop taking your medicine too soon.
For controlling acne, Akamin is normally taken for a few months.

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 the missed dose as soon as you remember, and then go back to taking your tablets or capsules 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 Akamin. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much Akamin you may experience the following symptoms: nausea, vomiting, stomach pain, fall in blood pressure, tiredness.

While you are taking Akamin

Things you must do

If you develop a persistent headache with one or more of the following symptoms – nausea, vomiting, blurred vision or dizziness; see your doctor immediately.
These may be signs of a rare condition associated with the use of minocycline called benign intracranial hypertension (increased pressure within the skull).
If you are taking Akamin for an infection and your symptoms do not improve within a few days, or if they become worse, tell your doctor.
If you become pregnant while you are taking Akamin, tell your doctor immediately.
If you get severe diarrhoea, tell your doctor or pharmacist immediately. Do this even if it occurs several weeks after you have stopped taking Akamin.
Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any medicines for the diarrhoea without checking with your doctor.
If you get a sore, white mouth or tongue while taking or soon after stopping Akamin, 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 Akamin allows fungi to grow and the above symptoms to occur. Akamin does not work against fungi.
Before starting any new medicine, tell your doctor or pharmacist that you are taking Akamin.
Tell all the doctors, dentists and pharmacists who are treating you that you are taking Akamin.
If you are taking Akamin for a long time, visit your doctor regularly so that they can check on your progress.
Your doctor may want you to have some blood tests from time to time.

Things you must not do

Do not stop taking Akamin or change the dose, without checking with your doctor.
If you do not complete the full course prescribed by your doctor, all of the bacteria causing your infection may not be killed. Your infection may not clear completely or may return.
Do not let yourself run out of Akamin over the weekend or on holidays.
Do not use Akamin to treat any other conditions unless your doctor tells you to.
Do not give Akamin to anyone else, even if they have the same condition as you.

Things to be careful of

Protect your skin when you are in the sun, especially between 10 am and 3 pm. If outdoors, wear protective clothing and use a SPF 30+ sunscreen.
Akamin may cause your skin to be much more sensitive to sunlight than it is normally. This may cause a skin rash, itching, redness or severe sunburn.
If your skin does appear to be burning, stop taking Akamin and tell your doctor.
Be careful driving or operating machinery until you know how Akamin affects you.
Akamin may cause dizziness or lightheadedness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
