How and when to take isotretinoin capsules - NHS
Accutane is a great treatment option for this otherwise difficult skin condition. However, it often comes with side effects such as dry eyes, nose and lips, muscle aches, etc. And like a TV drug commercial, I have to mention the less frequent but more severe possible side effects like vision loss, hearing loss, bone growth abnormalities, suicide risks, and GI symptoms.
But what if there was a dosage of Accutane that would still clear acne or excessively oily skin or rosacea papules often without the same side effects of the typical dosing? Sound too good to be true? Normal dose Accutane is regularly dosed based upon body weight and often increases slowly over the course of several months. A low dose regimen uses less milligrams and is taken less often.
For example, instead of taking a high dose of 40mg twice a day, the lower dose protocol might be 10mg, twice a week. This off-label use of Accutane provides great control of oiliness, as well as eliminating many, if not all of the common side effects. This also means we do not know what effects this protocol may have when used long term, or if this eliminates any or all of the more serious side effects.
We do, however, still believe that absolute birth control is a must for female patients. If you have persistent acne or oily skin into your adult years, come see us at Dermatology Realm and let us determine if the off-label use of Accutane may be something that is appropriate for your skin.

Objectives: To evaluate the clinical efficacy and tolerability of low-dose and intermittent isotretinoin regimens and to compare them directly with conventional isotretinoin treatment. The total period of drug administration was 6 weeks in group C, and 24 weeks in groups A and B. Evaluations included global acne grading system GAGS scores, lesion counts inflammatory and noninflammatory , patient satisfaction and side-effects. A 1-year follow-up evaluation after the end of treatment was also performed.
The patients were divided into 2 groups according to age: group I — patients aged between 12 and 20 years, and group II — patients aged from 21 to 35 years. Twenty two patients out of stopped the treatment. Improvement in skin lesions was observed, in group I in Within a 4-year observation period, recurrence was found in 3. Based on the obtained results, the authors conclude that 6-month therapy with low doses of isotretinoin is effective in moderate acne, adverse effects are rarely observed and the cost of treatment is lower than with the use of the conventional method.
A similar therapeutic regimen was used by Sardana et al. Prospective studies were carried out on patients diagnosed with moderately severe acne. The study was followed by a 6-month observation period. The study was completed by patients. The average cumulative dose taken by patients was Within a 6-month observation period, recurrences occurred in 50 In , Lee et al.
Sixty patients with moderate acne were qualified for the study. The subjects were divided into 3 groups; patients in group A were given isotretinoin at the dose of 0. Efficacy, tolerability of the therapy and patient satisfaction were compared in all groups. The therapy was followed by 1 year of observation. The number of both inflammatory and non-inflammatory lesions was statistically significantly different in groups B and C as well as C and A whereas there were no statistically significant differences between groups A and B, which suggests that conventional therapy and therapy with low doses of isotretinoin are similarly effective.
Patient satisfaction scores were the highest in group B low doses of the drug , lower in group C intermittent therapy and the lowest in group A conventional therapy. Adverse effects occurred most commonly in patients treated with the use of conventional method group A , compared to the groups treated with low doses of isotretinoin group B and intermittent method group C.
In conclusion, the authors highlight that considering tolerability, efficacy and patient satisfaction, the therapy with low doses of isotretinoin is most recommended for patients with moderate acne. In , Rasi et al. The retrospective study was done on patients 89 females, 51 males aged 18—40 years mean: The patient weight ranged from 50 to kg mean: Total clearance was achieved in out of patients treated with the use of this method The longest time of the therapy was 22 months, the shortest — 10 months.
Within a 5-year observation period, recurrences were found in 11 7. Mean time from treatment completion to a relapse was Adverse effects during the therapy were mild and included: cheilitis Slightly elevated levels of liver enzymes and lipids in serum were found in 20 subjects. The study was done on 50 patients 25 females, 25 males ; a half of the group received the above treatment regimen while the other half was given isotretinoin locally only.
The patients were divided into 2 age groups: group I consisted of patients aged 12—20 years while group II — those aged 21—35 years. After a 3-month therapy, an improvement was observed in Four patients did not complete the therapy. Within a 2-year observation period after the treatment, recurrences occurred in 3.
Rademaker et al. A randomized study with double-blind trial was carried out on 60 patients, aged 25—55 years. All patients underwent a check-up 10 weeks after completing the therapy 45 patients finished the study. There were statistically significant differences p placebo. The fastest significant reduction in skin lesions was observed within the first 4 weeks of the treatment group I. A systematic though less dynamic improvement was seen until the 32nd week of the therapy mean number of skin lesions before the therapy — The use of isotretinoin in Member States of the European Union, regulated by the Directive of the European Medicine Agency EMA , is approved for severe forms of acne, such as nodular or conglobate acne or acne at risk of scarring.
However, many groups of recognized experts, including the team appointed by the Polish Dermatological Society to develop consensus treatment for acne, recommend isotretinoin therapy also to patients with less severe acne [9].
The undeniable advantages of the intermittent therapy include: very good tolerability, easy management, and low cost. Improvement of the lesions is slower, the therapy is not accompanied by bothersome side effects, however, the therapy may run an increased risk of recurrence compared with the conventional treatment. A reduction in sebum production, cheilitis reported by most patients confirm activity of even low doses of isotretinoin.
Drug accumulation the concentration of retinoid returns to the physiological level after 2 weeks explains the improvement of the lesions despite interruptions in the application of the drug.
You may need a higher dose if your acne is not getting better. You may need a lower dose if you have side effects. Take isotretinoin capsules with food to make sure they work properly. It's best to take them straight after a meal or snack. A treatment course of isotretinoin capsules usually lasts for 16 to 24 weeks around 4 to 6 months.
Acne will usually keep getting better for up to 8 weeks after stopping treatment. Most people have clear skin after that time, but some will need another round of treatment. If you forget to take the capsules, take them as soon as you remember, unless it's nearly time for your next dose. In this case, skip the missed dose and take your next dose at the usual time. Never take 2 doses at the same time to make up for a forgotten dose.
To date, there are many reports regarding the efficacy of low-dose and intermittent isotretinoin treatment in patients with acne. Data comparing these three therapeutic regimens simultaneously, however, are unavailable. Objectives: To evaluate the clinical efficacy and tolerability of low-dose and intermittent isotretinoin regimens and to compare them directly with conventional isotretinoin treatment.
The total period of drug administration was 6 weeks in group C, and 24 weeks in groups A and B. Evaluations included global acne grading system GAGS scores, lesion counts inflammatory and noninflammatorypatient satisfaction and side-effects. A 1-year follow-up evaluation after the end of treatment was also performed. There was no significant difference between groups A and B. These results suggest that the conventional and low-dose regimens have similar efficacy. Intermittent treatment had less effect than either conventional or low-dose treatments.
This result suggests that the low-dose regimen is superior to other regimens conventional or intermittent in terms of patient satisfaction. Side-effects were more frequent with conventional treatment compared with low-dose and intermittent treatments. One year after the end of treatment, two of 16 patients relapsed in group A, three of 17 patients relapsed in group B, and nine of 16 patients relapsed in group C.
Conclusions: Our study suggests that, when considering tolerability, efficacy and patient satisfaction, low-dose treatment is most suitable for patients with moderate acne.

Its efficacy was proved by dermatologists and documented in many papers [1—6]. Isotretinoin is indicated mainly for keloid acne, phlegmonous and fulminans acne, as well for severe papulopustular acne resistant to antibiotics [7—9]. The recommended daily dosage ranges from 0. The effective therapy is associated with subsidence of symptoms, prevention of scar development, strengthening of treatment results and minimizing the risk of recurrence [1, 10, 11].
Isotretinoin may cause many adverse effects [12]; its teratogenic activity is the most serious, which means isotretinoin must not be taken during pregnancy. Effective contraception one month before, during and one month after the therapy is indicated [13]. The most common side effects include dry lips and cheilitis, blepharoconjunctivitis, rhinitis, erythema and dry facial skin, headaches, muscle and joint pains, and biochemical abnormalities such as increase in bilirubin, transaminase, triglycerides, decreased levels of high-density lipoprotein HDL and increased low-density lipoprotein LDL cholesterol and uric acid [9, 12, 14, 15].
Occurrence of adverse effects, often serious and arduous, in the course of conventional treatment with isotretinoin led to the search for alternative treatment regimens, associated with the use of lower doses of the medicine. In , Goulden et al. The therapy was continued for 6 months. The effectiveness of an intermittent therapy was also confirmed by the results published by Kaymak et al. In the study, 60 patients 34 females, 26 males, aged from 18 to 33 years were given isotretinoin for 7 days followed by a 3-week interval.
The patients were divided into 3 groups according to the severity of skin lesions by Leeds scale; group I — moderate acne 1. Partial improvement was observed in 6 patients from group I and 4 patients from group II. Based on the obtained results, the authors conclude that intermittent therapy with isotretinoin is a safe and effective method of treatment in patients with moderate and mild acne.
Multicentre, randomized and controlled studies were carried out by Akman et al. The authors compared intermittent and conventional isotretinoin therapies [18].
Sixty-six patients qualified for the study were divided into 3 groups: patients from group I were given isotretinoin at the dose of 0. After the treatment, the patients were observed for 12 months. Twenty-two patients from group I 19 females, 3 males, mean age: Acne score after the therapy was statistically significantly lower p Over the last 15 years, apart from papers on intermittent isotretinoin therapy, there have been papers on studies on patients given low doses of isotretinoin.
In , Mandekou-Lefaki et al. The study group consisted of 64 patients 35 females, 29 males divided into 2 groups. Thirty two subjects from group I received isotretinoin at the dose of 0. The authors conclude that the therapy with low doses is effective, causes fewer adverse effects, has a beneficial effect on scars while the conventional therapy is more effective, protects from recurrences and scarring.
In , Amichai et al. The patients were divided into 2 groups according to age: group I — patients aged between 12 and 20 years, and group II — patients aged from 21 to 35 years.

Our results suggest that the proposed intermittent low-dose therapy with isotretinoin is preferred by the patients, which is proved by patients with recurrences being willing to repeat the therapy. Although high doses of isotretinoin are recognized as a standard treatment, on the other hand, a number of clinical studies indicate that in most patients with a moderate form of acne, lower dosage of the drug is sufficient to achieve improvement and what is most important is safer because of significantly fewer side effects.
