Article 1 — Purpose and Scope
1.1
This Medical Disclaimer applies to all content published on 4PBA.org, including but not limited to educational articles, research summaries, dosage information, calculator tools, referenced scientific publications, user testimonials, and any other materials available at https://www.4pba.org (collectively, the “Content”).
1.2
The Content is provided exclusively for general educational and informational purposes. It is intended to help individuals understand the publicly available scientific and clinical literature relating to sodium phenylbutyrate (4PBA), also known as sodium 4-phenylbutyrate or 4-phenylbutyric acid.
1.3
By accessing or using this Site in any way, you acknowledge that you have read, understood, and accept the terms of this disclaimer in full.
Article 2 — Not Medical Advice
2.1
Nothing published on this Site constitutes, or should be understood to constitute:
(a) medical advice of any kind;
(b) a clinical diagnosis or assessment of any health condition;
(c) a recommendation to commence, continue, modify, or discontinue any treatment, therapy, or medication;
(d) a prescription or prescribing guidance for any pharmaceutical compound; or
(e) a substitute for consultation with a licensed, qualified healthcare professional.
2.2
The Content does not take into account the individual circumstances, medical history, current medications, comorbidities, or clinical needs of any particular user. Responses to pharmaceutical compounds, including 4PBA, vary substantially between individuals, and no informational resource can predict or advise upon outcomes for any specific person.
2.3
Nothing on this Site should be relied upon as a basis for self-diagnosis or self-treatment of any disease, condition, or symptom.
Article 3 — Regulatory Status of Sodium Phenylbutyrate (4PBA)
3.1 — United States
Sodium phenylbutyrate is approved by the US Food and Drug Administration (FDA) for use as adjunctive therapy in the chronic management of patients with urea cycle disorders (UCDs). This Site discusses 4PBA in the context of additional investigational uses that are not approved by the FDA and have not undergone full regulatory review for safety and efficacy in those contexts. Any discussion of investigational uses on this Site refers to off-label application of an approved drug. Users must understand that off-label use carries risks that differ from those established in approved indications, and must only occur under the supervision of a qualified physician.
3.2 — European Union and European Economic Area
In the European Union, sodium phenylbutyrate is authorised under specific conditions for certain metabolic disorders. Use of 4PBA for indications not covered by current EU marketing authorisations constitutes off-label use and, under Directive 2001/83/EC and applicable national medical law, is the sole clinical and legal responsibility of the prescribing physician. A prescribing physician undertaking off-label use is required to obtain appropriate informed consent from the patient. This Site does not constitute a basis for initiating or justifying any off-label treatment in any EU member state.
3.3 — United Kingdom
In the United Kingdom, the regulatory position mirrors the EU position described in Article 3.2. Off-label prescribing is governed by guidance from the Medicines and Healthcare products Regulatory Agency (MHRA) and the General Medical Council (GMC). Prescribers bear full clinical responsibility for off-label decisions.
3.4 — All Jurisdictions
In all jurisdictions, the Content on this Site reflects published research, publicly available literature, and community-submitted information. Publication of this information on this Site does not constitute evidence of regulatory approval, clinical validation, or endorsement of any use of 4PBA by 4PBA.org.
Article 4 — The Dosage Calculator
4.1
The dosage calculator available on this Site is a general educational reference tool. It uses publicly available data from scientific and clinical literature as a basis for its calculations.
4.2
Calculator outputs are approximate estimates only. They do not account for individual clinical variables including, without limitation:
(a) renal function and estimated glomerular filtration rate;
(b) hepatic function;
(c) age-related pharmacokinetic variation;
(d) body composition and lean body mass;
(e) concurrent medications and potential drug interactions;
(f) specific disease context, stage, or aetiology; or
(g) known or unknown contraindications applicable to the individual user.
4.3
Calculator outputs must not be used as the sole basis for any dosing decision. All dosing decisions must be made by, or in consultation with, a qualified and licensed medical professional with knowledge of the individual patient’s clinical circumstances.
4.4
The Site operator accepts no liability for any harm or adverse outcome resulting from reliance on the dosage calculator.
Article 5 — No Professional Relationship

(d) any other professional or fiduciary relationship between the user and 4PBA.org, its operator, or any individual whose content appears on the Site.
5.2
No communication made through this Site — including form submissions, email correspondence, or any other channel — constitutes a clinical consultation, a medical opinion, or a professional recommendation of any kind.
