But the new study found higher than expected percentages of patients developing these abnormal lab results. Among patients with normal lab tests before they started taking the drug, 44 percent developed high levels of triglycerides.
The package insert, by contrast, cites high triglycerides in 25 percent of patients. Thirty-one percent of healthy patients in the study developed high cholesterol levels and 11 percent developed abnormal liver tests. The patients ranged in age from 13 to 50 and were treated between March and September They were all members of the Kaiser Permanente health plan in northern California. Some patients in the study had more lab tests than others during their treatment with the acne drug, but, for their analysis, the researchers used only the most abnormal test result for each different test each patient had.
The researchers also looked at lab tests for levels of white blood cells, hemoglobin and platelets. They found these were rarely abnormal. Strauss is a former consultant for Roche Laboratories Inc. The drug is sometimes the only way to treat severely disfiguring acne, Strauss said. Some risk could be acceptable for patients whose acne is severe, he said. IE 11 is not supported.

NBC News Logo. Isotretinoin is a prescription drug for the treatment of severe or persistent acne. It may be a suitable option when other treatments for acne have not been effective. Isotretinoin is the generic version of this medication, which people often refer to by its original brand name, Accutane.
However, this brand is no longer on the market. A course of isotretinoin treatment may take 4—5 months. During this time, people will need monitoring to check for any adverse side effects. One possible side effect is liver damage, although this is uncommon. In this article, we look at the potential effects of isotretinoin on the liver, how to protect the liver while taking the medication, and other possible side effects.
Isotretinoin is a retinoid and derivative of vitamin A. A doctor may prescribe isotretinoin to treat severe or persistent acne or some types of skin, neck, or head cancer.
Isotretinoin works to reduce the size of sebaceous glands and lower sebum production, which helps decrease acne. Isotretinoin may also work to reduce cell proliferation.
People take isotretinoin orally in capsule form. Due to the potential side effects of isotretinoin, a healthcare professional will need to monitor people while they are taking the drug. This monitoring may involve blood tests, liver function tests, and checking for any other side effects. Isotretinoin may lead to higher levels on liver function tests. Isotretinoin may increase serum aminotransferase, which can be an indicator of liver damage. There is no known reason why isotretinoin may elevate serum aminotransferase, but high dosages of the drug may have a toxic effect on the liver.
However, it is rare for isotretinoin to cause abnormally high results in a liver test, and it is rare for the drug to lead to liver injury.
Abnormal liver test results in people taking isotretinoin are usually temporary and may resolve while people are still taking the medication. Abnormal liver test results will usually not cause any symptoms.
A doctor will need to monitor people with regular liver tests while they are taking isotretinoin to check for any liver abnormalities.
Increased levels of serum aminotransferase usually resolve without treatment, and changes in dosage or medication may not be necessary. However, if serum aminotransferase levels reach more than five times the upper limit, a doctor may discontinue the medication. Before taking isotretinoin, a person must have a blood test and agree to certain terms, which include:.
It is important that people let the prescribing doctor know if they are taking any other medications, herbal remedies, or supplements before taking isotretinoin.
The American Liver Foundation notes that people can help promote good liver health, in general, by:. People will also need to talk with a doctor about whether it is safe for them to drink alcohol while taking isotretinoin. The most common side effect of isotretinoin is dry skin, particularly dry lips.
The medication can also cause dryness of the mouth , nose, or eyes, as well as increased sensitivity to the sun. People will need to take steps to protect their skin from the sun while taking isotretinoin, such as wearing sunscreen. Due to increased skin sensitivity, people will also need to avoid certain skin procedures, such as waxing, dermabrasion, or laser therapy, for at least 6 months after stopping isotretinoin.
Other potential risks of isotretinoin include:. People taking isotretinoin will need to see a doctor every 30 days for monitoring, which may include blood tests and liver function tests. If people have any symptoms of jaundice , they will need to contact the doctor as soon as possible, and it may be necessary to discontinue the medication. The symptoms of jaundice include a yellowing of the skin and eyes. People will also need to contact the doctor if they have any concerns about the symptoms or notice any changes in their mental health.
A course of 15—20 weeks of daily isotretinoin may lead to a complete, prolonged lack of acne symptoms. Elevations in liver function tests usually do not cause any symptoms and may resolve while people are still taking isotretinoin. Liver injury from isotretinoin that is significant enough to appear in testing is very rare. This program ensures that the person meets certain requirements, such as following the advice of a healthcare professional, agreeing to take steps to avoid pregnancy, and taking any necessary medical tests.
Isotretinoin is a prescription retinoid to treat severe acne. It may cause elevations in certain liver enzymes that can be an indicator of liver inflammation or damage. Abnormal liver test results from isotretinoin are not usually a cause for concern, and they may resolve while people are still taking the drug.

RESULTS: Of the patients who received isotretinoin between January and Decemberonly 70 were actually treated for 3 months or more and handed in the results of their laboratory tests. Of these 70 patients, 39 The mean age of the women There was a statistically significant increase in the levels of triglycerides These findings are in accordance with data published previously in the scientific literature, confirming the need to monitor these patients.
II PhD, Professor. Keywords: acne vulgaris; aminotransferases; dermatologic agents; isotretinoin; triglycerides. The comedone, which consists of a blocking of the follicular duct with sebum and keratin, forms the primary lesion. This pathology is classified into two types: inflammatory and non-inflammatory acne, although both types may coexist. The disease may be clinically separated, therefore, into four classification levels: grade 1, the mildest form of non-inflammatory acne, with the presence of comedones; grade II, inflammatory or papulopustular acne in which papules and pustules are associated with comedones; grade III, nodulocystic acne in which nodules are also present; and grade IV, conglobate acne.
The treatment of acne depends on its severity and in cases of non-inflammatory acne or mild inflammatory acne treatment consists entirely of topical products such as tretinoin, isotretinoin, adapalene, benzoyl peroxide and azelaic acid, either alone or in combination.
In more severe cases of acne, systemic treatment with antibiotics or isotretinoin may be used. On the other hand, when acne is caused by hyperandrogenism of adrenal or ovarian origin such as in the case of polycystic ovary syndrome, treatment should be in accordance with the origin of the excess androgen production. The use of isotretinoin or cis-retinoic acid is recommended for the treatment of severe inflammatory acne of the nodulocystic or conglobate types and for cases of acne that have proven resistant to previous treatments with antibiotics or topical medication.
In addition, many studies have shown that the cumulative dose is more important than the daily dose for remission of the disease. Isotretinoin probably acts on the sebaceous gland by binding to specific retinoid receptors, modifying gene transcription. The drug reduces the activity and size of the gland, decreasing the quantity of sebum it produces following four weeks of treatment.
Furthermore, retinoids such as isotretinoin act by normalizing keratinization in the sebaceous follicle and the number of Propionibacterium acnes. This drug has a considerable number of adverse effects.
Of these, teratogenicity is the most significant, while mucocutaneous effects including cracked lips, dryness of the skin and nose, redness of the skin, eye irritation and deterioration of the acne are the most common. Other less common side effects consist of fatigue, weakness, hair loss and headache. Isotretinoin use may also lead to liver alterations such as increased serum levels of liver enzymes liver aminotransferases and to lipid changes, including increased triglyceride, total cholesterol and low-density lipoprotein LDL cholesterol levels and reduced levels of high density lipoprotein HDL cholesterol.
In humans, the increase in plasma triglyceride levels due to the use of retinoids is accompanied by an increase in apolipoproteins C-III levels, which may contribute, at least in part, to the hypertriglyceridemia induced by retinoids.
Nevertheless, other studies are required to determine whether retinoids affect plasma triglyceride levels by regulating the genes that control triglyceride metabolism.
Due to the clinical significance of the possible adverse reactions caused by isotretinoin, the Clinical and Therapeutic Guidelines Protocol issued by the Brazilian Ministry of Health recommends carrying out liver function tests ALT and ASTtotal cholesterol, triglycerides, glucose, full blood count, platelets and prothrombin time. In addition, a pregnancy test is required prior to initiating treatment with the drug.
The presentation of the abovementioned test results is mandatory for the patient to receive the drug at the pharmacies for special drugs. To continue treatment with isotretinoin, repeat ALT, AST and triglyceride measurements are requested after 30 days and every three months thereafter.
In Brazil, studies to evaluate the prevalence of alterations in aminotransferases and triglycerides in patients using oral isotretinoin are rare. Therefore, the objective of the present study was to evaluate the profile of alterations in ALT, ASL and triglyceride levels in patients using oral isotretinoin for the treatment of severe cases of acne.
All the patients who had received oral isotretinoin at a pharmacy for special drugs in the town during were included in this exploratory study. Each patient's clinical record form was self-completed with information on age, weight, skin color, address and city of residence. In addition, a copy of the laboratory tests performed and a copy of the prescription were attached to the patient's records together with other documents. The study data were collected by analyzing each patient's clinical records.
Since the study consisted of a secondary data collection, no informed consent form was required. The choice of the statistical tests was based on sample size and on the normal distribution of the data according to the Kolmogorov-Smirnov test to verify whether parametric or non-parametric tests should be applied.
In the case of variables with a normal distribution parametricStudent's t-test was used to compare means between two groups and ANOVA for three or more groups. To compare proportions, Fisher's exact test was used. To establish correlations between variables, Spearman's correlation coefficient was calculated. Between January and Decemberpatients initiated treatment with isotretinoin dispensed by the town's pharmacy for special drugs. Of these, 60 patients were excluded from the study because they had not completed a minimum treatment period of three months 26 patients or had not presented the tests required to enable treatment to be monitored 34 patients.
The study population consisted of 39 women Age ranged from 13 to 42 years, with a mean of The mean age of the women was Regarding skin color, Sixty-nine of the patients provided information on their weight, which ranged from 43 to kg, with a mean of The duration of isotretinoin treatment ranged from 4 to 12 months, with The patients evaluated took daily doses of isotretinoin that ranged from 20 to 80 mg, with a mean of At the beginning of treatment, mean triglyceride level was In the case of AST, the mean baseline value in these patients was Mean ALT level increased from The incidence of patients whose normal biochemical baseline values changed after three or more months is described in table 1.
These results differ from those presented above, since they refer only to patients with normal values prior to treatment, excluding those patients with uncontrolled levels at baseline. When the mean difference was calculated between baseline triglyceride, AST and ALT levels and those measured after three months or more of oral isotretinoin treatment, a statistically significant difference was found between the two time points Table 2. In an attempt to clarify the trend towards significance for the daily dose per weight of the patient and to establish whether this trend was related to the patient's weight or if there was some other variable that was affecting the levels of ALT, AST and triglycerides, three multiple linear regression models were constructed.
In the first model, the dependent variable was ALT after three months or more of treatment, while in the second model the dependent variable was AST after three months or more of treatment and in the third model the dependent variable was triglycerides after three months or more of treatment.
The backwards entry method was used in this analysis, which showed that no independent variable was capable of explaining the model. The results of this study showed that the mean age of the women was greater than the mean age of the men, possibly because acne usually affects men at puberty due to hormone changes, while women are more often affected in adulthood. This may occur due to the effect of neuromediators and the state of hyperandrogenism on the persistence of acne, as well as on the delayed onset of the disease.
Although various studies have confirmed these results, the magnitude of the alterations has varied greatly between studies. Furthermore, there was no homogeneity between studies with respect to the criteria used to define normal and abnormal laboratory results, which limits any comparisons.
Moreover, these considerations may explain the fact that other studies have failed to find any significant alterations in triglyceride levels or liver aminotransferases. The increase in triglyceride levels in patients being treated with oral isotretinoin may be related to a reduction in the removal rate of these lipids from plasma. In agreement with reports from other studies, no correlation was found between the oral dose of isotretinoin and the increase in triglycerides.
In addition, no significant increases occur with chronic treatment over long periods. This finding raises a concern, since there is a possibility that this increase in triglyceride levels during isotretinoin treatment may increase the risk of developing metabolic syndrome. Other studies have also shown an increase in the LDL-cholesterol fraction and a reduction in the HDL fraction, together with an increase in triglycerides in patients in use of isotretinoin for eight weeks or more.
However, the alterations in the lipid profile of these patients induced by isotretinoin appear to be transitory, since they return to baseline levels approximately eight weeks after the end of treatment. It should be emphasized that total cholesterol and fractions were included as follow-up tests for the use of oral isotretinoin in the Ministry of Health's Clinical and Therapeutic Guidelines Protocol published on March 31, These tests were not required in the earlier protocol published in Although the present study found statistically significant increases in liver aminotransferases, they were clinically irrelevant in the majority of patients.
Only one patient had an increase in ALT that was classified as grade 2, i. In situations such as this, Altman et al. The increased levels of triglyceride, AST and ALT found in the present study reinforce the importance of having the patient monitored by a multidisciplinary team.
The patient should be counseled on the importance of a balanced diet with low fat intake and restricted alcohol consumption in order to prevent or minimize possible biochemical alterations that contribute towards increasing the risk of cardiovascular, metabolic or liver disease. In this respect, various studies have shown that the introduction of certain food supplements into the patient's diet may prevent or minimize the increases in triglyceride levels caused by oral isotretinoin treatment.
Multiple linear regression analysis showed that none of the independent variables was able to explain the model, although there were correlations between some variables in the univariate analysis.
This trend in correlation between the variables and the biochemical results highlights the need to conduct studies with larger sample sizes. Finally, the present study was limited to analyzing the biochemical abnormalities without taking into consideration the follow-up data on the clinical repercussions that these abnormalities may have caused in the patients.
The study also failed to register the occurrence of adverse events that could have predicted the alterations in the lipid profile and liver function, since this was a retrospective study based on secondary data.
In this respect, the importance of conducting prospective studies to evaluate these aspects should be emphasized in view of the fact that findings may lead to adjustments to the current guidelines.
These results show that in the population evaluated in this study the use of oral isotretinoin for the treatment of acne led to increases in serum triglyceride, ALT and AST levels. Although these alterations did not require treatment to be interrupted, they may increase the patient's risk of developing cardiovascular and liver disease, confirming data already published in the literature. For this reason, rigorous monitoring with lipid profile measurements and liver function tests is indispensable in order to minimize the inherent risks of treatment with this drug.
Furthermore, it is important to emphasize the role of the pharmacist in the pharmacotherapeutic follow-up interview to ensure that the drug is dispensed appropriately and that the patients are being adequately monitored.
