Drug Information

Cleo can look up detailed drug information from FDA drug labels. Ask about dosing, side effects, pregnancy safety, mechanism of action, and more.

How It Works

When you ask about a medication, Cleo retrieves information from FDA-approved drug labels via DailyMed, the official repository of FDA drug labeling.

What You Can Ask

Question	Information Returned
”What’s the dose of metformin?”	Dosing and administration guidelines
”Side effects of lisinopril?”	Adverse reactions and their frequency
”Is amoxicillin safe in pregnancy?”	Pregnancy and lactation information
”How does metoprolol work?”	Mechanism of action
”Warnings for warfarin?”	Boxed warnings and precautions

Tip

You can ask using brand or generic names. Cleo will find the matching FDA label.

Example Results

When you ask “What’s the dose of metformin?”, Cleo returns:

METFORMIN HYDROCHLORIDE

### Dosage and Administration

Adults: Starting dose is 500 mg twice daily or 850 mg once
daily, given with meals. Increase in increments of 500 mg
