Overview of Eubiolac Verla

Property Description
Active Ingredient Calcium Lactate Pentahydrate
Form Vaginal Tablet
Pharmacological Class Vaginal pH Regulator / Acidifier
Common Principle Eubiotic Support (Flora Stabilization)
Origin Derived (Synthetic Salt of a Natural Metabolite)

Eubiolac Verla is a trademarked pharmaceutical preparation specifically formulated for local gynaecological application, serving as a specialized Vaginal Acidifier and pH Regulator. It is available as an over-the-counter (OTC) product in its primary markets, allowing accessibility for patients seeking to address symptoms associated with flora imbalance.


What Type of Medicine is Eubiolac Verla?

Eubiolac Verla is a local therapeutic agent, delivered exclusively in the pharmaceutical form of a Vaginal Tablet, which ensures precise vaginal route of administration. Its function aligns with the eubiotic principle, supporting the growth of beneficial micro-organisms. Pharmacological studies have consistently confirmed the effectiveness of lactic acid-based preparations in rapidly restoring the protective pH environment, making it a recognized choice for women seeking to stabilize the vaginal environment.


Composition and the Lactic Acid Principle

The core component is Calcium Lactate Pentahydrate, which acts as a stable precursor that releases Lactic Acid upon dissolution. This active functional agent, Lactic Acid, is a natural metabolite crucial for maintaining the healthy acidic pH in the vaginal milieu. The specific formulation in a tablet matrix is designed to provide a controlled and sustained release, differentiating its action profile from immediate-release liquid alternatives. This gradual release is clinically recognized to help sustain the optimal acidic environment over time.


The General Purpose: Why Use a Vaginal pH Regulator?

The general purpose of Eubiolac Verla is to restore and stabilize the acidic milieu of the vagina, thereby supporting the natural, protective bacterial colonization. The released Lactic Acid lowers the vaginal pH, creating conditions that are optimal for the growth of beneficial Lactobacilli and simultaneously unfavorable for opportunistic, harmful organisms. By strengthening the vagina's natural self-defense capabilities, the product helps relieve the general discomfort and symptoms associated with an imbalanced microbial flora.

Therapeutic Uses of Eubiolac Verla

What Eubiolac Verla Treats: Main Uses and Benefits

Eubiolac Verla is relevant for managing symptoms related to vaginal flora imbalance and contributes to improved comfort during periods of heightened symptoms. Its therapeutic benefit is associated with its role in balancing the vaginal environment.


Managing Symptoms of Microbial Imbalance

The medication is commonly used in conditions characterized by periods of heightened symptoms, such as vaginal dysbiosis, and may be part of symptomatic management for conditions associated with pH imbalance, such as Bacterial Vaginosis (BV). The therapeutic domain is relevant for managing symptom clusters that may become intense or disruptive, such as symptoms related to physical discomfort like odor and discharge irregularities. This approach is considered relevant when supportive symptom management is appropriate, as studies confirm the role of pH support in stabilizing the vaginal environment.

“The general purpose of supportive care is to reinforce the natural defenses by contributing to a balanced vaginal environment.”

Support for Flora Stabilization and Recurrence Management

Eubiolac Verla is applied in clinical settings that involve acute or unstable symptom patterns, such as post-antibiotic therapy. It contributes to improved comfort during periods of heightened symptoms and may assist in supporting patients during difficult episodes. It may be applied in addressing recurrent or episodic manifestations, which helps with maintaining comfort and stability during symptomatic periods.


Quick Fact: Relief for Odor and Discharge Eubiolac Verla is commonly used to help with symptoms that interfere with daily functioning and create noticeable physiological strain, particularly those related to changes in vaginal odor and discharge.

Eligibility and Restrictions for Use

The official eligibility for Eubiolac Verla is determined by regulatory bodies based on specific population and physiological criteria. The medicine is intended for use by adult women and is permitted for use by adolescents who have reached menarche (the onset of menstruation). Absolute prohibitions define who must not use the medicine.

Eligibility Status Summary

Population Group Regulatory Status
Hypersensitivity to Ingredients Contraindicated
Girls Before Menarche Contraindicated
Pregnant Women Permitted (often advised with caution)
Breastfeeding Women Permitted
Hepatic or Renal Impairment No documented restrictions

Eligibility is strictly contraindicated for individuals with a known hypersensitivity to Calcium Lactate Pentahydrate or any other component in the formulation. Use is prohibited in pre-pubescent girls. Furthermore, use for self-medication is restricted in the presence of severe local symptoms, such as unexplained vaginal bleeding, pain, or fever; these require prior consultation with a healthcare professional before use.

What should I know about interactions with other medicines?

Interactions with other medicines and products

The interaction profile for Eubiolac Verla is narrowly focused on medicinal products that can interfere with the activity of its live bacterial components. Official regulatory documents primarily identify a single class of agents with a documented interaction: antibiotics.

Documented Interaction

Interacting Product Category Mechanism/Effect Regulatory Condition
Antibiotics Reduction or complete loss of Eubiolac Verla's effect due to inactivation of the live bacteria by the antimicrobial agent. Simultaneous use is prohibited and requires strict spacing.

Timing-Based Administration Constraint

To ensure the viability of the live microorganisms in Eubiolac Verla and prevent the therapeutic effects from being reduced or abolished, simultaneous administration with antibiotics is prohibited. A minimum time interval of at least two hours must be observed between the intake of Eubiolac Verla and the antibiotic. Patients should ensure that the administration of this product is strictly separated by this time period from any antibiotic dose.

No other specific medicinal products, substance categories, or pharmacokinetic-based interaction mechanisms are explicitly listed or mandated in the official interaction sections beyond this essential timing constraint with antibiotics.

Mechanism of Action

The mechanism of Eubiolac Verla is based on local physiochemical modulation, focusing on the alteration of the vaginal pH environment via the sustained release of Lactic Acid.


Direct Physiochemical pH Modulation

The central mechanism involves the Lactic Acid component acting as a proton donor to precisely and rapidly lower the local pH to the natural acidic range (approximately 3.8 to 4.5). This change in pH is the primary action, immediately creating an environment that is non-permissive for the growth of most pH-sensitive microorganisms.


Selective Microbial Ecosystem Support

The restored acidic pH imposes a powerful selective pressure on the local microbiota. This environmental shift strongly supports the proliferation and colonization of acid-loving endogenous Lactobacilli. The resulting dominance promotes continuous Lactic Acid production, stabilizing the local pH equilibrium.


Sustained Equilibrium via Controlled Release

The Lactic Acid is released gradually from the tablet matrix, demonstrating a sustained pattern of pH modulation on the local ecology. This controlled-release kinetic facilitates the stable and long-term equilibrium of the pH environment, allowing endogenous Lactobacilli to sustain the acidic milieu.

Dosage and Administration Information

Official Administration Guidelines

Administered exclusively via the vaginal route, Eubiolac Verla is dosed as one vaginal tablet daily (one dose per 24 hours). The administration is typically scheduled for the evening before retiring, which promotes sustained contact of the dissolving tablet with the vaginal walls. The tablet contains 61 mg of Calcium Lactate Pentahydrate and is designed for deep insertion.


The duration of use depends on the clinical approach. For the primary course of restoration, official instructions recommend a consecutive treatment period of six to twelve days. If the vagina is particularly dry, the tablet may be slightly moistened with water prior to insertion to facilitate dissolution. A key procedural restriction is the requirement to interrupt the treatment regimen during the menstrual period and resume once it concludes.


For patients with recurring needs or those undergoing destabilizing treatments like antibiotic therapy, the official protocol allows for intermittent, long-term stabilization. This maintenance use can involve the administration of one tablet, one to two days per week, over several months. While generally permitted for use during pregnancy and lactation as prescribed, administration in children requires prior medical consultation.
