Direct guidance
What to know or do
For “High-dose vitamin A or retinol supplement,” use the lower-exposure choice instead of trying to cancel the exposure afterward. Do not stop medicine for epilepsy, mental health, blood pressure, asthma, diabetes or another long-term condition on your own.
What changes the answer
- The exact active ingredient, strength, dose, route and formulation
- Why you use it, how often, and the pregnancy week or exposure date
- Other prescriptions, non-prescription products, supplements and health conditions
General guidance
When to get individual help
Choose a lower-risk alternative when possible. If the exposure already happened, record the product, amount, timing and symptoms and ask for advice instead of assuming harm.
