1. What is Biosteron and what is it used for

The active substance of Biosteron is dehydroepiandrosterone (DHEA), which is a steroid hormone produced in the adrenal glands and released into the blood.
In various tissues, DHEA is converted into active sex hormones: estrogens and androgens.
The highest concentrations of DHEA in serum occur during youth (2nd and 3rd decade of life), after which there is a slow decline, to about 10-20% in people aged 80.
A deficiency of DHEA may be the cause of unfavorable phenomena associated with the aging process, such as:

  • memory impairment, intellectual performance, concentration ability;
  • worsening of well-being and depression;
  • psychological and physical complaints related to menopause in women and andropause in men;
  • reduced muscle strength, feeling of excessive fatigue, chronic fatigue syndrome;
  • reduced stress resistance;
  • decreased libido and reduced sexual potency;
  • obesity, reduced tissue sensitivity to insulin, which can cause diabetes;
  • atherosclerosis;
  • sleep disorders;
  • reduced immunity to viral and bacterial infections.

Supplementing DHEA deficiency may counteract the above-mentioned processes and phenomena, and ultimately improve the health and quality of life of aging individuals.

Indications for use

Biosteron is indicated for supplementing dehydroepiandrosterone (DHEA) deficiencies.

2. Important information before taking Biosteron

When not to take Biosteron:

  • if the patient is hypersensitive (allergic) to the active substance or any of the other ingredients of Biosteron;
  • if the patient has breast, ovarian, or other estrogen-dependent cancer;
  • if the patient has benign prostatic hyperplasia or prostate cancer;
  • if the patient has severe liver failure;
  • if the patient has severe kidney failure;
  • during pregnancy and breastfeeding.

Warnings and precautions

  • Patient under 40 years of age should discuss taking Biosteron with their doctor.
  • If severe side effects occur, the medicine should be discontinued and a doctor consulted.
  • If side effects such as acne or skin oiliness occur, the medicine should be discontinued for 2-3 weeks. After this time, treatment can be continued with a lower dose than before, and it is recommended to consult a doctor. If side effects recur, the medicine should not be taken.

Biosteron is not indicated for use in children and adolescents.

Biosteron and other medicines

Taking Biosteron with hormone replacement therapy (HRT) may lead to increased estrogen levels and excess. Therefore, the medicine should not be taken by women receiving HRT.
Men treated with testosterone should not take Biosteron due to the possibility of enhanced effects.
DHEA may weaken the effect of certain medicines, such as:

  • antiepileptic drugs (e.g., carbamazepine, valproic acid);
  • psycholeptics (phenothiazine derivatives, diazepines, and oxazepines). It is not recommended to take Biosteron with these medicines due to the possibility of reduced efficacy.

In case of any doubts, a doctor or pharmacist should be consulted .

Biosteron with food and drink

Biosteron should be taken with a meal to facilitate its absorption.

Pregnancy and breastfeeding

During pregnancy, breastfeeding, or if pregnancy is suspected, or if pregnancy is planned, a doctor or pharmacist should be consulted before taking this medicine.
Biosteron is contraindicated during pregnancy and breastfeeding.
If a woman taking Biosteron becomes pregnant, she should stop taking the medicine and contact her doctor as soon as possible.

Driving and using machines

The effect of Biosteron on the ability to drive and use machines has not been studied.

Biosteron contains lactose

If the patient has previously been diagnosed with intolerance to some sugars, they should consult their doctor before taking the medicine.

3. How to take Biosteron

Biosteron should be taken once a day, in the morning, in accordance with the natural rhythm of DHEA secretion. The medicine should be taken with a meal to facilitate its absorption.
The recommended initial single dose of DHEA for women is 5 mg, and for men, it is 10 mg. The initial dose of the medicine should be gradually increased (by 5 to 10 mg every 2 weeks).
The maximum recommended daily dose of DHEA for women is 25 mg, and for men, it is 50 mg.
The effect of the medicine is not immediate and occurs after several weeks of administration; therefore, Biosteron is intended for long-term use.
In case of the need to use doses higher than 25 mg per day in women and 50 mg per day in men (only with a doctor's prescription), the DHEA concentration in serum should be regularly determined, and medical examinations should be performed frequently.

Elderly patients

Elderly patients usually require higher doses of the medicine due to decreased DHEA production. However, the use of doses higher than recommended should be preceded by a consultation with a doctor.

Use in children and adolescents

Biosteron is not indicated for use in children and adolescents.

Overdose of Biosteron

There are no known cases of acute DHEA overdose in humans.
In case of taking a higher dose than recommended, a doctor or pharmacist should be consulted immediately.

Missed dose of Biosteron

Biosteron is intended for long-term supplementation of DHEA deficiency, and missing a single dose is not associated with a significant reduction in the efficacy of the medicine.
A double dose should not be taken to make up for a missed tablet.
In case of any further doubts related to the use of this medicine, a doctor or pharmacist should be consulted .

4. Possible side effects

Like all medicines, Biosteron can cause side effects, although not everybody gets them.
Properly used Biosteron is a safe medicine and very well tolerated. Side effects are rare, dose-dependent, and transient after discontinuation of therapy.
