ACNETANE contains per capsule 10 mg or 20 mg isotretinoin. ACNETANE is a chemical derivative of vitamin A and it is used to treat severe, resistant, nodular acne, after other anti - acne medicines have failed to help. It works by decreasing the activity of the sebaceous glands in the skin and therefore prevents the formation of acne lesions. ACNETANE is given as a 4 - 8 month first course of treatment, depending on the daily dose taken. A second course of treatment may be prescribed, if needed, 8 weeks after completing the first course. ACNETANE is a scheduled medicine and not a cosmetic. It should therefore be kept in a safe place and not be shared with any person who does not have a valid prescription to use it.
1. What ACNETANE is and what it is used for
2. What you need to know before you take ACNETANE
Do not take ACNETANE:
- if you are hypersensitive (allergic) to isotretinoin or any of the other ingredients of ACNETANE, to any other medicines, or to soya (listed in section 6).
- If you are pregnant or intend to become pregnant or breastfeeding your baby (see important warning for females below).
- If you have liver disease.
- If you have very high levels of blood fats (e.g. high cholesterol or triglycerides).
- If you have very high levels of vitamin A in your body (hypervitaminosis A).
- If you are receiving treatment with tetracyclines (a type of antibiotic) at the same time (see “Other medicines and ACNETANE”).
Warnings and precautions
- Please consult your doctor, pharmacist or other healthcare professional for advice, if you are taking other medicines on a regular basis, including complementary or traditional medicines, prescription medicines and medicines bought without a prescription, especially tetracycline antibiotics, vitamin A and other anti - acne medicines. The use of ACNETANE with these medicines may cause undesirable interactions.
- Exfoliating anti - acne preparations should NOT be used while you are taking ACNETANE. Mild topical products may be used if recommended by your doctor.
- NOTE: It is important that you do not take vitamin A supplements while on ACNETANE. Make sure that any multivitamins you take do not contain vitamin A.
- Do not have any wax treatment to remove hair while you take ACNETANE Capsules and for 6 months after you stop treatment.
- ACNETANE makes your skin sensitive to the sun and UV radiation. Do NOT use a sunlamp. Avoid the sun as much as possible. Wear a good sunscreen, protective clothing and a hat when outdoors.
- ACNETANE has been associated with serious skin reactions. Any rash may become serious. Stop using ACNETANE and call your doctor right away if you develop conjunctivitis (red or inflamed eyes like “pink eye”), a rash with fever, blisters on legs, arms or face and/or sores in your mouth, throat, nose, eyes, or if your skin begins to peel.
- ACNETANE may cause dry eyes. If you wear contact lenses, you may need to use an eye lubricating solution or wear your spectacles while you take ACNETANE.
- ACNETANE may change your night vision. If this happens, do not drive or do anything else that requires you to see well. Also, speak to your doctor. This will revert to normal after the treatment.
- Do not donate blood while you are taking ACNETANE or for 30 days after you stop taking it. This is to avoid the possibility of a pregnant woman receiving your blood that contains ACNETANE.
- ACNETANE has been prescribed particularly for you. Never share medicines prescribed for you with others.
3. How to take ACNETANE
• Do not share medicines prescribed for you with any other person. Always use ACNETANE exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
• Take ACNETANE with food or milk once or twice a day.
• The dose of ACNETANE will be different for different patients. It is based on your bodyweight. Your doctor may later change your dosage depending on your response and if side effects occur. NOTE: Acne may be worsened at first. Do not stop taking the medicine as it is essential that you continue treatment during this phase.
• The usual dose of ACNETANE for adult and teenagers is 0,5 to 1,0 mg per kg.
• A treatment course is usually 4 - 8 months depending on the daily dose. After stopping treatment, many patients notice a further improvement and repeated courses are not usually needed. If a definite relapse does occur, a repeat course may then be given but should only be started at least 8 weeks after stopping the first course. Your doctor will tell you how long your treatment with ACNETANE will last. Do not stop treatment early unless you have spoken to your doctor.
If you have the impression that the effect of ACNETANE is too strong or too weak, tell your doctor or pharmacist.
If you take more ACNETANE than you should
Acute toxicity of ACNETANE is low. However, in case of overdose or accidental intake, consult your doctor or pharmacist. If neither is available, contact the nearest hospital or poison control centre.
If you forget to take ACNETANE
If you miss a dose, take it as soon as you can. However, if it is nearly time for your next dose, skip the missed dose and carry on as before. Do not take / receive a double dose to make up for forgotten individual doses.
