To answer whether a specific drug can be consumed by a 19-year-old, I would need to know the exact name of the drug in question. Drug safety and suitability depend on the medication type, dosage, the individual's health status, and any underlying conditions.

If you provide the name of the drug, I can offer guidance on its use in young adults, including any age restrictions, common precautions, and potential side effects.

Meanwhile, here are some general points to consider:

• Consult a healthcare professional: Always check with a doctor or pharmacist before starting any medication.
• Follow prescribed dosage: Never take more or less than recommended.
• Be aware of allergies or interactions: Inform your healthcare provider about any other medications or allergies.

Please share the drug name for more specific advice.
