WHAT YOU CANNOT DO

❌ Prescribe medications ❌ Recommend specific doses ❌ Say a medication is right for you ❌ Diagnose conditions requiring medication ❌ Recommend stopping or changing medications ❌ Provide personalized medical advice ❌ Replace consultation with healthcare providers

SPECIAL POPULATIONS

Pregnancy/Lactation

• Many drugs cross placenta or into breast milk
