Frequently asked questions
Where does the medication data come from?
Side-effect frequencies come from the U.S. FDA Adverse Event Reporting System (FAERS), and interactions, warnings and drug-class information come from official FDA drug labels — both via the public openFDA API. We do not write or invent any medical content.
Are these side effects ranked by how likely they are?
Not exactly. They are ranked by how often each reaction has been reported to the FDA. Reporting is voluntary, so these counts show what is reported most — not the true incidence rate. A common report does not mean it will happen to you, and a rare one does not mean it is unimportant.
Does this work for Canadian medications?
Drug pharmacology and side effects are the same worldwide, so the safety information applies broadly. The data itself is from the U.S. FDA, and brand names can differ in Canada — always check your own prescription label and Health Canada resources.
Can you tell me a safer alternative to my medication?
No. We show other medications in the same drug class for context only. Whether any alternative is safer or appropriate for you depends on your full medical picture — only your doctor or pharmacist can advise that. Never stop or switch a medication on your own.
Is this medical advice?
No. This is a free educational tool. It is not a substitute for professional medical advice, diagnosis or treatment. Always consult a licensed healthcare professional, and in an emergency call 911.
