1. What VialMath is

VialMath is a free arithmetic and record-keeping tool. It does arithmetic on numbers you enter. It does not recommend doses, diagnose, treat, or give medical advice. It is intended only to do arithmetic on numbers you enter and to keep a personal record. It is not a pharmacy or healthcare provider, and it does not sell medication.

2. You are responsible for your inputs and decisions

Always follow your prescriber's and pharmacist's instructions. Confirm any result with them before acting on it. Check units (mg, mcg, mL, units) carefully. If a result doesn't match your instructions, don't use it; ask a professional.

3. Age

You must be 18 or older to use VialMath.

4. Lawful use only

Use VialMath only for medications prescribed for you by a licensed provider and dispensed by a licensed pharmacy. Don't use it with products labeled "research use only" or "not for human consumption." VialMath does not endorse or provide information on where to get any substance.

VialMath is provided "as is" without warranties of any kind, including accuracy, fitness for a particular purpose, or availability. We test the math carefully, but software can have errors.

To the fullest extent allowed by law, VialMath and its operators are not liable for any damages arising from use of, or inability to use, the tool.
