About IBSA Pharmaceuticals

IBSA is a pharmaceutical company with a portfolio spanning several therapeutic areas, including reproductive medicine.

Within fertility treatment, IBSA is associated with hormone-based medicines used to support specific reproductive processes under medical supervision.

The products featured in this category include:

• Merional: A menotropin preparation containing follicle-stimulating hormone (FSH) and luteinizing hormone (LH) activity.

• Fostimon: A urofollitropin preparation containing follicle-stimulating hormone (FSH).

• Choriomon: A human chorionic gonadotropin (hCG) preparation.

Although these products are associated with reproductive healthcare, they differ in their active ingredients and clinical purposes.

Their labeled strengths are expressed in international units (IU), which represent standardized biological activity rather than a conventional mass measurement such as milligrams.

Understanding IBSA Fertility Medications

Merional – Menotropins (HMG)

Merional is a menotropin preparation associated with human menopausal gonadotropin (HMG).

Menotropins provide FSH and LH activity, which are involved in reproductive hormone signaling.

Products listed in this category include:

• Merional 75 IU

• Merional 150 IU

These figures identify the labeled hormone activity of the respective preparations. Exact packaging and formulation details should be confirmed against the individual product information.

Fostimon – Urofollitropin (FSH)

Fostimon contains urofollitropin, a purified form of follicle-stimulating hormone.

FSH is involved in ovarian follicle development and other reproductive processes.

The IBSA category includes:

• Fostimon 75 IU

• Fostimon 150 IU

The distinction between 75 IU and 150 IU describes labeled biological activity. It does not establish a treatment recommendation or determine which formulation is appropriate for a particular patient.

Choriomon – Human Chorionic Gonadotropin (hCG)

Choriomon is associated with human chorionic gonadotropin, commonly abbreviated as hCG.

Human chorionic gonadotropin is a hormone involved in reproductive physiology and is used in certain medically supervised fertility treatments.

The product listed in this category is Choriomon HCG 5000 IU, with a listing describing one vial and one solvent ampoule.

Choriomon should not be confused with Merional or Fostimon. Although these medicines are related to reproductive medicine, they contain different active substances.

Understanding IU Strengths in IBSA Products

IBSA reproductive hormone preparations commonly express labeled strength in international units (IU).

An international unit measures biological activity according to a recognized standard. It is not directly equivalent to a fixed number of milligrams across different hormones.

For example:

• Merional 75 IU: A menotropin preparation labeled at 75 IU.

• Merional 150 IU: A higher labeled-strength menotropin preparation.

• Fostimon 75 IU: A urofollitropin preparation labeled at 75 IU.

• Fostimon 150 IU: A urofollitropin preparation labeled at 150 IU.

• Choriomon 5000 IU: A human chorionic gonadotropin preparation labeled at 5000 IU.

IU values should not be compared across different hormone products as though they represent equivalent pharmacological effects.

IBSA Product Identification and Comparison

When identifying or comparing IBSA products, important specifications include:

• Product name: Merional, Fostimon, or Choriomon.

• Active ingredient: The specific hormone contained in the medicine.

• Labeled strength: The biological activity expressed in IU.

• Dosage form: The preparation and its intended pharmaceutical formulation.

• Package contents: The number of vials, solvent ampoules, and other included components.

• Manufacturer information: The manufacturer identified on the packaging.

• Storage requirements: Conditions specified in the official product information.

Products containing different reproductive hormones should not be treated as substitutes solely because they share a manufacturer or therapeutic category.

Product Information & Safety

IBSA reproductive hormone medicines are used in clinical settings where appropriate patient selection, medical assessment, and monitoring are important.

Potential adverse effects vary by active ingredient and treatment context.

Certain gonadotropin treatments may be associated with ovarian hyperstimulation syndrome (OHSS), multiple pregnancy, injection-site reactions, and other complications. Some adverse reactions can be serious and require prompt medical attention.

Hormonal medicines may also have contraindications related to particular medical conditions, hormone-sensitive disorders, or reproductive health circumstances.

Patients should follow the instructions of qualified healthcare professionals and the official prescribing information for the specific medicine.
