What Isotretinoin Lupin is used for

Isotretinoin Lupin contains the active ingredient isotretinoin.

Isotretinoin Lupin is used to treat acne.

Isotretinoin Lupin belongs to a group of medicines called retinoids, which are similar to vitamin A.

The retinoids work by reducing the amount of the oily substance (ie. sebum) made by glands in your skin, reducing bacteria, reducing inflammation and opening clogged pores.

There are many different types of medicines used to treat acne. Isotretinoin Lupin is used for more severe cases.

Your doctor, however, may have prescribed Isotretinoin Lupin for another purpose.

Ask your doctor if you have any questions about why Isotretinoin Lupin has been prescribed for you.

This medicine is available only with a doctor’s prescription.

Isotretinoin Lupin is not addictive.

When you must not take it

Do not take Isotretinoin Lupin if:

1. you are pregnant, or for at least one month before you plan to fall pregnant.
If you fall pregnant while taking Isotretinoin Lupin there is an extremely high risk of having a baby that is severely deformed. You must use effective contraception for one month before, during and one month after treatment.
2. you are breastfeeding.
Breastfeeding must stop before treatment begins. Do not breastfeed while taking Isotretinoin Lupin.

  2. you are taking tetracycline antibiotics (such as Akamin, Vibramycin, doxycycline hydrochloride (Doryx), Frakas, Minomycin).
  3. you have severe liver disease.
  4. you have very high fat levels (cholesterol, triglycerides) in your blood.
  5. you have hypervitaminosis A. This is a condition caused by an excessive amount of vitamin A in the diet.

Before you start to take it

Taking other medicines

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

Some medicines may interfere with Isotretinoin Lupin. These include:

  • tetracycline antibiotics (such as Akamin, doxycycline hydrochloride (Doryx), Frakas, Vibramycin, Minomycin);
  • vitamin A, or preparations containing vitamin A (including vitamin supplements);
  • other medicines you are using to treat your acne;
  • the “mini-pill”, a progestogen-only oral contraceptive pill.

These medicines may be affected by Isotretinoin Lupin, or may affect how well it works. You may need to take different amounts of your medicine, or you may need to take different medicines. Your doctor will advise you.

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

Ask your doctor or pharmacist if you are not sure about this list of medicines.

How to take Isotretinoin Lupin

How much to take

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

Take Isotretinoin Lupin exactly as your doctor has prescribed. Your doctor will tell you how many Isotretinoin Lupin capsules to take each day.

This dose will be calculated to suit your individual needs and your body weight. This dose may be adjusted during treatment when the doctor knows how you respond to Isotretinoin Lupin.

How to take it

Capsules should be swallowed whole with a glass of water or milk.

Do not open the capsules and do not take any capsules that are damaged.

When to take it

Isotretinoin Lupin may be taken once or twice a day and must always be taken with meals.

Female patients should wait until the 2nd or 3rd day of their next normal menstrual period before starting Isotretinoin Lupin treatment. This helps ensure that you aren’t pregnant before you start taking Isotretinoin Lupin.

How long to take it

Continue taking Isotretinoin Lupin for as long as your doctor prescribes.

Acne treatment with Isotretinoin Lupin will usually last 4 to 8 months. In the first few weeks of treatment your acne will probably get a little worse before it gets better.

Do not worry about this, it is a sign that Isotretinoin Lupin is working.

At the end of this time your acne should have cleared up significantly. Most patients notice their skin condition continues to improve even after Isotretinoin Lupin treatment is finished.

Please note that Isotretinoin Lupin cannot improve scars or pitting that were present before treatment started, but it will help prevent such skin damage in the future.

If you forget to take it

Do not try to make up for missed doses by taking an extra dose. This may increase the chance of getting an unwanted side effect.

If it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to.

If you have missed several doses, please inform your doctor and follow the advice given to you.

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 you or anyone else may have taken too much Isotretinoin Lupin.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Signs of overdose include transient headache; vomiting; facial flushing; reddened, cracked lips; stomach pain; headache; dizziness and unsteady walking.

Keep telephone numbers for these places handy.

While you are taking Isotretinoin Lupin

Things you must do

If you become pregnant while taking Isotretinoin Lupin, stop taking it and tell your doctor immediately. Isotretinoin Lupin can cause birth defects (damage to unborn babies). You must use strict birth control, starting at least 1 month before you begin taking Isotretinoin Lupin, for the whole time you are taking Isotretinoin Lupin and for 1 month after you finish taking Isotretinoin Lupin.

There is no known risk to males who wish to father children.

Tell all doctors, dentists and pharmacists who are treating you that you are taking Isotretinoin Lupin.

Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.

Tell your doctor if you feel Isotretinoin Lupin capsules are not helping your condition.

Be sure to keep all of your appointments with your doctor so that your progress can be checked. Your doctor may ask you to have regular blood tests to monitor your liver function, blood sugar levels and blood cholesterol levels.

If you are intending to do a lot of heavy lifting or exercise, tell your doctor. Your muscles and joints may be more prone to tenderness or stiffness if you do a lot of heavy exercise while taking Isotretinoin Lupin.

Things you must not do

Do not stop taking Isotretinoin Lupin or change the dose without first checking with your doctor.

Do not let yourself run out of medicine over the weekend or on holidays.

Do not give Isotretinoin Lupin to anyone else even if their symptoms seem similar to yours.

Do not use Isotretinoin Lupin to treat other complaints unless your doctor says to.

Do not donate blood during treatment with Isotretinoin Lupin or for at least 1 month after stopping treatment.

Things to be careful of

Be careful driving or operating machinery until you know how Isotretinoin Lupin affects you. Normally Isotretinoin Lupin would not affect your ability to drive a car or operate machinery. However altered night vision and other visual disturbances may occur when taking Isotretinoin Lupin. Make sure you know how you react to Isotretinoin Lupin before you drive a car, operate machinery or do anything else that may be dangerous if your vision is affected.

Wearing contact lenses during treatment with Isotretinoin Lupin may cause discomfort. Isotretinoin Lupin may cause dry eyes. An eye lubricant or artificial tears, available from your pharmacist, should relieve this problem. Otherwise, you may temporarily need to wear your lenses for shorter periods or wear glasses instead.

Avoid excessive sun exposure and solariums and apply a sunscreen while taking Isotretinoin Lupin. Your skin may be more prone to sunburn while on Isotretinoin Lupin.

Avoid waxing and dermabrasion while taking Isotretinoin Lupin and for 5 to 6 months after stopping Isotretinoin Lupin treatment. Your skin may be more sensitive while on Isotretinoin Lupin. Waxing may cause dermatitis and dermabrasion may cause scarring during and for several months after Isotretinoin Lupin treatment.

Avoid using facial peels, electrolysis and some hair treatments. Your skin and hair may be more delicate during treatment and for a while after Isotretinoin Lupin treatment.

Side effects

Isotretinoin Lupin helps most people with acne but it may have unwanted side effects in a few people.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

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

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

Tell your doctor if you notice any of the following and they worry you:

  • dryness of the lips, mouth, nose and skin. A moisturiser or petroleum jelly can be used to soften the lining of the nose, lips and the skin areas not affected by the acne;
  • fragile skin;
  • change in colour of the skin;
  • peeling palms of the hands and soles of the feet;
  • itchy skin rash;
  • an increased susceptibility to sunburn;
  • sweating;
  • changes to the nails;
  • eye problems such as dry, sore, swollen or itchy eyes, discharge or trouble seeing at night;
  • nosebleeds;
  • tenderness or stiffness in your bones, joints or muscles;
  • tiredness;
  • headache;
  • hair loss (sometimes occurs and is usually temporary but in rare cases, has persisted);
  • excessive hairiness;
  • hoarseness
  • sexual changes or changes in breast tissue.

These side effects are usually mild and dose related. Most of them disappear completely in a few days to a few weeks after the dose of Isotretinoin Lupin is lowered or stopped.

Tell your doctor immediately if you experience any of the following:

  • nausea;
  • vomiting;
  • persistent headache;
  • blurred vision or visual disturbances;
  • changes in your hearing or ringing in your ears;
  • severe upper stomach pain;
  • blood in stools or severe diarrhoea;
  • severe bruising;
  • sudden red, often itchy spots, similar to the rash of measles starting on the face, hands or feet. The spots may blister or change to flat round raised, red, pale-centred marks. Also, you may have fever, sore throat, headache and/or diarrhoea;
  • painful red areas, that change to large blisters and end with peeling of layers of skin, that may occur on lips, mouth, eyes, nose and genitals. Those affected may have fever and chills, aching muscles and generally feel unwell;
  • thinking, seeing or hearing things that are not real;
  • feeling depressed, with or without suicidal thoughts.

Symptoms of depression may include:

  • feeling sad or having crying spells;
  • losing interest in activities you once enjoyed;
  • sleeping too much or having trouble sleeping;
  • changes in your appetite or body weight;
  • having trouble concentrating;
  • withdrawing from your friends or family;
  • feeling like you have no energy;
  • feelings of worthlessness or inappropriate guilt.

These may be serious side effects. You may need urgent medical attention. Serious side effects are rare.

This is not a complete list of all possible side effects. Others may occur in some people and there may be some side effects not yet known.

Tell your doctor if you notice anything else that is making you feel unwell, even if it is not on this list.

Ask your doctor or pharmacist if you don’t understand anything in this list.
