Acne: causes, treatment and modern solutions
Acne is a chronic skin condition that most often appears on the face, back and chest. It not only causes visible cosmetic imperfections, but also significantly affects the patient’s emotional well-being. Due to its complex nature, acne requires a comprehensive approach to treatment.
One of the most widely discussed medications for acne therapy is Accutane. It demonstrates strong therapeutic results thanks to its specific composition and has proven to be more effective and safer in many cases than long-term antibiotic use.
In some countries Accutane is available only with a doctor’s prescription, while in others it can be purchased more freely, including through online pharmacies. Regardless of the source, treatment should always be carried out under medical supervision with strict adherence to dosage and duration. Depending on the severity of acne, a typical course may last up to six months.
Therapeutic effects of Accutane include:
-
reduction of inflammation
-
regulation of sebum production
-
normalization of skin renewal processes
Already during treatment patients often notice visible changes: reduced oiliness, less irritation, fewer breakouts and a healthier skin tone.
Even if acne has left marks in the form of scars, modern cosmetology offers solutions such as laser resurfacing, photo-therapy and other advanced techniques that can help restore a smooth and clear complexion.
Accutane remains one of the most effective modern remedies for persistent acne, providing long-lasting improvement and helping patients regain confidence in their appearance.
How to take Accutane: dosage and recommendations
The dosage and administration of Accutane are always selected individually, depending on the severity of acne, patient’s age, overall health and other factors. Although the medication is considered effective and generally well tolerated, treatment should be supervised by a dermatologist who determines the appropriate dose and duration.
Oral administration
When taken orally, Accutane should be used with meals, usually twice a day. Both effectiveness and possible side effects depend on the dose, which often requires adjustment during therapy.
-
Initial dose: 0.5 mg per kg of body weight per day.
-
Standard range: 0.5–1.0 mg/kg/day.
-
Severe cases (extensive or body acne): up to 2.0 mg/kg/day.
Clinical studies show that the optimal cumulative course dose is 120–150 mg/kg, which typically corresponds to 16–24 weeks of treatment. For most patients, one full course is enough to achieve complete remission. In case of relapse, a repeat course may be prescribed at the same daily dosage, but no earlier than 8 weeks after discontinuation, since improvement may continue for several weeks after stopping the drug.
Patients with severe renal insufficiency should begin with a lower dose (e.g., 10 mg/day) and gradually increase up to 1 mg/kg/day under medical supervision.
Rectal administration
Rectal Accutane may be prescribed at a dose of 0.5–1 mg/kg once daily, usually in the evening.
External use
For acne or rosacea, Accutane ointment can be applied in a thin layer to clean skin twice a day. A standard course lasts 4–12 weeks. Repeated treatment is possible after consultation with a doctor.
Overdose risks
Although isotretinoin has relatively low toxicity, accidental overdose may cause symptoms of hypervitaminosis A. These effects are usually reversible. If an overdose occurs (most often with oral intake), gastric lavage may be required within the first few hours.
Drug interactions
-
Combining isotretinoin with other retinoids (acitretin, tretinoin, retinol, adapalene) increases the risk of hypervitaminosis A.
-
Concomitant use with tetracyclines is contraindicated due to the risk of increased intracranial pressure.
-
Accutane may reduce the effectiveness of progesterone-based contraceptives; therefore, low-dose progesterone preparations should be avoided.
-
Drugs that increase photosensitivity (sulfonamides, tetracyclines, thiazide diuretics) raise the likelihood of sunburn during therapy.
Side effects of Accutane: how to avoid them
No medication is completely free from side effects, and Accutane online (isotretinoin) is no exception. Its possible adverse reactions have been documented in numerous clinical studies and are largely dose-dependent. When used at the correct dosage and under medical supervision, most patients tolerate the drug satisfactorily.
Common side effects
The majority of symptoms resemble those of hypervitaminosis A:
-
dryness of mucous membranes (lips, nose, throat)
-
nasal dryness with possible nosebleeds
-
hoarseness due to throat irritation
-
dry eyes, sometimes leading to conjunctivitis or temporary blurred vision
To manage these effects, dermatologists often recommend using moisturizing ointments for the lips and special lubricating eye drops. Contact lens intolerance is also frequent during treatment, so patients are advised to switch to glasses.
Less common reactions
Some patients report:
-
increased skin sensitivity to sunlight (photosensitivity)
-
photophobia, impaired night vision, cataracts (rare)
-
inflammatory conditions such as vasculitis (e.g., Wegener’s granulomatosis)
-
changes in blood counts (anemia, neutropenia, thrombocytopenia)
-
dermatological issues: rash, itching, dermatitis, nail dystrophy, excessive granulation tissue, or temporary hair loss
Muscle and joint pain (myalgia, arthralgia), excessive sweating, pigmentation changes, or flare-ups of acne are also possible.
Rare but serious side effects
In isolated cases, isotretinoin has been linked to:
-
inflammatory bowel disease (colitis, ileitis, gastrointestinal bleeding)
-
hyperuricemia (increased uric acid levels)
-
neurological and psychiatric effects (headache, depression, seizures, benign intracranial hypertension)
-
bone changes and premature epiphyseal closure with long-term, high-dose use
Laboratory changes
Accutane may cause an increase in triglycerides and cholesterol levels, as well as a decrease in HDL cholesterol. These effects are reversible after dose reduction or treatment discontinuation. Patients with diabetes, obesity, alcohol dependence, or a family history of lipid disorders are at higher risk and require regular blood tests during therapy.
Important considerations
Accutane should only be prescribed for severe forms of acne, and always under dermatologist supervision. Most side effects are temporary and subside after adjusting the dosage or stopping the medication.
For full details and personalized advice, patients should consult their prescribing doctor or pharmacist.
