Medical Disclaimer
Last updated: July 2026
MedicationHow2 has two sections, built to different levels of verification. Read the section that applies to what you're looking at — the two disclaimers below are not interchangeable.
Medication Guide
The medication names, drug classes, and typical dosing figures shown in this section were generated with the assistance of AI language models, not compiled directly from an official pharmaceutical database, a licensed pharmacist's review, or manufacturer prescribing information. While this content is intended to reflect generally accurate, publicly known information, it has not been independently verified entry-by-entry.
Do not rely on any dosing figure on this site to determine how much of a medication to take. Always verify dosing information directly with a pharmacist, physician, or the official prescribing information that came with your specific medication.
The Medication Guide is intended as a general starting point for learning about a medication's name, general drug class, and typical use case — the kind of orientation you might want before a doctor's appointment or a pharmacy conversation. It is not designed, and should not be used, as a clinical reference for making an actual treatment decision.
Appropriate medication and dosing depends on factors specific to you that a general reference tool has no way to know — your age, weight, kidney and liver function, other medications and supplements you take, allergies, pregnancy status, and other health conditions. Only a healthcare provider with your actual medical history can make that determination.
This section does not perform interaction checking. If you take more than one medication or supplement, ask your pharmacist to review your full list for interactions — this is a service most pharmacies provide and is far more reliable than any general information source.

Vitamin Guide
The Vitamin Guide is an educational reference, not a source of medical advice, diagnosis, or treatment.
This section does not provide medical advice
The information in this section, including vitamin and nutrient function descriptions, food sources, and the articles in our guides, is provided for general educational purposes only. It is not intended to diagnose, treat, cure, or prevent any disease or health condition, and it should not be used as a substitute for professional medical advice, diagnosis, or treatment.
Always consult a qualified healthcare provider
Before starting, stopping, or changing any supplement, medication, or diet, consult a physician, pharmacist, registered dietitian, or other qualified healthcare provider who can evaluate your individual health history, current medications, and specific needs.
Supplement and nutrient risks
Vitamins and nutrients, including those generally considered safe, can interact with medications, other supplements, or existing health conditions, and can cause harm in excessive amounts, particularly fat-soluble vitamins that the body stores over time. What's appropriate for one person may not be appropriate for another.
Why we exclude certain substances
Our database deliberately excludes compounds marketed as vitamins that are not recognized as such by mainstream nutritional science, including substances historically sold as "vitamin B15" and "vitamin B17." Excluding a substance from our database is not the same as a complete safety assessment of that substance; if you have encountered a product marketed this way, we encourage you to research it independently through a licensed healthcare provider or a recognized health authority before use.
Using this site does not create a doctor-patient, dietitian-client, or any other professional healthcare relationship.
