How does this medication work? What will it do for me?

Alitretinoin is a vitamin A derivative that belongs to the class of medications called retinoids. Retinoids are usually used to treat skin problems. Alitretinoin is used to treat severe chronic hand eczema that has not responded to other measures such as protecting the skin, avoiding irritants and allergens (triggers) and the use of high potency topical corticosteroids. It may take 2 months to notice improvement of skin symptoms.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

What form(s) does this medication come in?

Toctino is no longer being manufactured for sale in Canada. For brands that may still be available, search under alitretinoin. This article is being kept available for reference purposes only. If you are using this medication, speak with your doctor or pharmacist for information about your treatment options.

How should I use this medication?

The usual starting dose of alitretinoin is 30 mg taken once daily at the same time every day with a meal. People who experience severe side effects may find it necessary to reduce the dose to 10 mg daily. The 30 mg dose will cause the skin to clear faster, but both strengths work to clear the skin.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Alitretinoin should be taken with food, preferably with a main meal.

This medication is usually taken for 12 to 24 weeks depending on your response. If your eczema is still severe after 12 weeks, discuss with your doctor whether continuing the medication will improve your skin.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Blood donation: You should not give blood during treatment with alitretinoin and for one month after stopping treatment in case the blood is given to a pregnant woman.

Bones and joints: Alitretinoin may cause some minor bone changes. Talk to your doctor if you notice aches or pains in the bones or joints, or have difficulty moving. Your doctor may monitor you for bone changes while you are taking this medication.

Cholesterol: Alitretinoin can cause increases in cholesterol and other lipids in the blood. If you are already at an increased risk of developing high cholesterol, for example if you have a family history of high cholesterol, diabetes, are overweight, or have an increased alcohol intake, you are more likely to experience this.

If you are at any increased risk of developing increased blood lipids, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Depression and suicidal thoughts: Retinoid medications have been known to cause mood swings and symptoms of depression. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.

Diabetes: Alitretinoin may cause a loss of control of blood sugar levels for people with diabetes. If you have diabetes, or anyone in your family has diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. You may need to check your blood glucose levels more often.

Stomach and bowels: Alitretinoin may cause inflammatory bowel disease (IBD). If you have inflammatory bowel disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

If you experience severe abdominal pain, rectal bleeding, or severe diarrhea, you should stop using this medication and contact your doctor.

Liver function: Retinoids like alitretinoin have been linked to inflammation of the liver in some cases. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.

If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor as soon as possible.

Neurologic effects: Alitretinoin has been linked to causing intracranial hypertension (increased pressure around the brain), also known as pseudotumor cerebri. Early symptoms of this condition include headache, nausea, vomiting, and visual disturbances. If you have these symptoms call your doctor immediately.

Pancreatitis: Retinoids can cause the pancreas to become inflamed. If you have a history of pancreatitis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Report signs of pancreatitis such as abdominal pain on the upper left side, back pain, nausea, fever, chills, rapid heartbeat, or swollen abdomen to your doctor immediately.

Skin care: Alitretinoin causes irritated, dry skin and lips. Ask your doctor or pharmacist for appropriate moisturizers and lip balms to use to prevent severe dryness. While you are taking alitretinoin, avoid exfoliators, waxing, and dermabrasion.

Sun sensitivity: Alitretinoin may make you more likely to burn in the sun. Use appropriate measures to prevent excessive exposure to the sun. Wear a hat and sunglasses when out in the sun, use a sunscreen that provides an SPF of 30 or higher, and avoid going out in the sun between 10 am and 2 pm when the sun is at its strongest. Avoid using sun lamps and tanning beds.

Thyroid disease: This medication may cause changes in thyroid function. The thyroid gland produces hormones that help the body make energy and organs work properly. If you experience unexpected fatigue, intolerance to cold or weight gain, contact your doctor as soon as possible. If you have thyroid problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your thyroid function regularly with blood tests while you are taking this medication.

Vision: This medication may cause dry eyes. This usually disappears after stopping the medication. Using a lubricating eye drop may help with this side effect. Also, decreased night vision has been reported by people taking alitretinoin . This may happen suddenly and without warning. Use caution when driving or operating any vehicle at night. Report any night vision changes to your doctor. Stop taking the medication and seek immediate medical attention if you notice other signs of vision changes, such as blurred vision, distorted vision, or a cloudy surface on the eye.

Vitamin supplements: You should not take vitamin supplements containing vitamin A if you also take alitretinoin as this may increase the side effects of vitamin A. Talk to your doctor or pharmacist if you are not sure which of your supplements might contain vitamin A.

Pregnancy: Alitretinoin causes severe birth defects in an extremely high percentage of infants born to people who take this medication even for a short period of time during pregnancy.

Alitretinoin must not be used during pregnancy. You must not become pregnant while taking alitretinoin or for at least one month after stopping the medication. Your doctor may perform monthly pregnancy tests while you are taking alitretinoin to confirm the safety of continuing to take this medication.

People who may become pregnant must not be given alitretinoin until pregnancy is excluded. A pregnancy test must be performed at the initial assessment appointment with your doctor. A second pregnancy test must be performed within 11 days of starting treatment. Alitretinoin treatment should start on the second or third day of the next normal menstrual period following this negative pregnancy test. Effective birth control must be used for at least one month before starting alitretinoin treatment, during the treatment, and for at least one month following the discontinuation of treatment.

Two reliable forms of birth control should be used at the same time during treatment unless abstinence is the chosen method.

Breast-feeding: It is likely that alitretinoin passes into breast milk. If you are breast-feeding and taking this medication, it may harm your baby. People who are taking this medication must not breast-feed.

Children: The safety and effectiveness of using this medication have not been established for children. Alitretinoin is not recommended for use if you are under the age of 18.

Seniors: The use of alitretinoin by seniors has not been well studied. It is likely that seniors would be at an increased risk for side effects from this medication.
