 Precautions

Pregnancy: Category X. There is an extremely high risk of deformity to the infant if pregnancy occurs while taking this drug in any amount, even for short periods. Potentially, all exposed fetuses can be affected. Presently, there are no accurate means of determining after isotretinoin exposure which fetus has or has not been affected. Lactation: Undetermined. CHILDREN: Safety and efficacy not established. Acne: Transient exacerbation of acne may occur, generally during initial therapy period. Childbearing potential: Isotretinoin is contraindicated in women of childbearing potential unless all conditions of the consent form included with the product information are met. See product information and Patient Information leaflet. Inflammatory bowel disease: Inflammatory bowel disease, including regional ileitis, has been temporally associated with isotretinoin use. Musculoskeletal effects: Decreases in lumbar spine and total hip bone mineral density have been observed. Osteoporosis, osteopenia, bone fracture, and delayed healing of bone fractures as well as premature epiphyseal closure have been seen in patients receiving isotretinoin. Pancreatitis: Acute pancreatitis has been reported with elevated or normal serum triglyceride levels. In rare cases, fatal hemorrhagic pancreatitis has been reported. Psychiatric disorders: May cause depression, psychosis, and rarely, suicidal ideation, suicide attempts, and suicide. Photosensitivity: May occur; avoid excessive sunlight and ultraviolet light.

PATIENT CARE CONSIDERATIONS

 

 Administration/Storage

• Instruct patient to swallow capsules whole. Do not open or crush capsules.
• Give medication with meals.
• Second course of therapy may be initiated if needed after 2 mo off therapy.
• Store in tightly closed, light-resistant container at room temperature.

 

 Assessment/Interventions

• Obtain patient history, including drug history and any known allergies. Note hypersensitivity to parabens.
• Obtain baseline lipid levels and then monitor q 2 wk for first month and then monitor monthly.
• Obtain LFTs at 2- to 3-wk intervals for first 6 mo and then every month throughout course of therapy.
• In diabetic patients, monitor glucose levels carefully.
• If increased triglyceride levels occur, discontinue drug immediately.
• Notify health care provider of signs and symptoms of decreased liver function (eg, dark urine, jaundice, pruritus), visual disturbances, nausea, vomiting, and headache.

OVERDOSAGE: SIGNS & SYMPTOMS   Transient headache, vomiting, facial flushing, cheilosis, abdominal pain, dizziness, ataxia

 

 Patient/Family Education

• Because of teratogenic effects, instruct patient to practice abstinence or use 2 reliable methods of birth control during therapy and for 1 mo before and after therapy.
• Advise patient to be seen by health care provider monthy and have a urine or serum pregnancy test performed each month to confirm negative pregnancy status.
• Instruct patient to notify health care provider immediately if pregnancy is suspected.
• Advise patient to take medication with meals.
• Instruct patient to discontinue any other acne medications (including OTC topical preparations) before starting therapy.
• Advise patient to control weight, decrease dietary fat, and restrict alcohol intake 36 hr before lipid determinations to avoid elevation in serum triglycerides.
• Caution patient against use of vitamin A, even in multivitamins, to avoid additive toxicity.
• Inform patient that contact lens tolerance may decrease.
• Suggest use of lubricant (eg, petroleum jelly) on lips to prevent cheilitis.
• Advise patient not to donate blood for at least 30 days after discontinuing therapy.
• Inform patient that transient exacerbations of acne may be experienced during first few weeks of therapy. Advise patient to continue drug therapy because this may be normal response.
• Caution patient that decreased night vision can occur and onset can be sudden. Advise patient to be cautious when driving or operating any vehicle at night.
• Advise patient to take sips of water frequently, suck on ice chips or sugarless hard candy, or chew sugarless gum if dry mouth occurs.
• Caution patient to avoid exposure to sunlight and to use sunscreen or wear protective clothing to avoid photosensitivity reactions.
• Caution patient that problems could arise in the control of blood sugar.
• Inform patient of availability of Patient Information leaflet, emphasizing the need to carefully review pregnancy warnings and fetal risks.
• Prior to use, have patient complete a consent form included with package insert.
• Instruct patient to immediately notify health care provider if any of the following symptoms occur: depression, visual disturbances, abdominal pain, rectal bleeding, severe diarrhea, difficulty in controlling blood sugar, decreased tolerance to contact lens.
• Inform patient to avoid wax epilation and skin resurfacing procedures (eg, dermabrasion, laser) during therapy and for at least 6 mo thereafter because of possible scarring.

 Precautions

Pregnancy: Category X. There is an extremely high risk of deformity to the infant if pregnancy occurs while taking this drug in any amount, even for short periods. Potentially, all exposed fetuses can be affected. Presently, there are no accurate means of determining after isotretinoin exposure which fetus has or has not been affected. Lactation: Undetermined. CHILDREN: Safety and efficacy not established. Acne: Transient exacerbation of acne may occur, generally during initial therapy period. Childbearing potential: Isotretinoin is contraindicated in women of childbearing potential unless all conditions of the consent form included with the product information are met. See product information and Patient Information leaflet. Inflammatory bowel disease: Inflammatory bowel disease, including regional ileitis, has been temporally associated with isotretinoin use. Musculoskeletal effects: Decreases in lumbar spine and total hip bone mineral density have been observed. Osteoporosis, osteopenia, bone fracture, and delayed healing of bone fractures as well as premature epiphyseal closure have been seen in patients receiving isotretinoin. Pancreatitis: Acute pancreatitis has been reported with elevated or normal serum triglyceride levels. In rare cases, fatal hemorrhagic pancreatitis has been reported. Psychiatric disorders: May cause depression, psychosis, and rarely, suicidal ideation, suicide attempts, and suicide. Photosensitivity: May occur; avoid excessive sunlight and ultraviolet light.

PATIENT CARE CONSIDERATIONS

 

 Administration/Storage

• Instruct patient to swallow capsules whole. Do not open or crush capsules.
• Give medication with meals.
• Second course of therapy may be initiated if needed after 2 mo off therapy.
• Store in tightly closed, light-resistant container at room temperature.

 

 Assessment/Interventions

• Obtain patient history, including drug history and any known allergies. Note hypersensitivity to parabens.
• Obtain baseline lipid levels and then monitor q 2 wk for first month and then monitor monthly.
• Obtain LFTs at 2- to 3-wk intervals for first 6 mo and then every month throughout course of therapy.
• In diabetic patients, monitor glucose levels carefully.
• If increased triglyceride levels occur, discontinue drug immediately.
• Notify health care provider of signs and symptoms of decreased liver function (eg, dark urine, jaundice, pruritus), visual disturbances, nausea, vomiting, and headache.

OVERDOSAGE: SIGNS & SYMPTOMS   Transient headache, vomiting, facial flushing, cheilosis, abdominal pain, dizziness, ataxia

 

 Patient/Family Education

• Because of teratogenic effects, instruct patient to practice abstinence or use 2 reliable methods of birth control during therapy and for 1 mo before and after therapy.
• Advise patient to be seen by health care provider monthy and have a urine or serum pregnancy test performed each month to confirm negative pregnancy status.
