Is doxepin a controlled substance?
Doxepin is generally not classified as a controlled substance in the United States. It is a prescription antidepressant (a tricyclic antidepressant), but it is not in the federal controlled-substances schedules like many sedatives or opioids.
What schedule would it be if it were controlled?
In the U.S., only drugs listed under schedules I–V are “controlled substances.” Doxepin is not listed under those schedules under federal law, so it would not have a schedule number (1–5).
Could it still be restricted in other ways?
Even when a drug is not federally controlled, doctors and pharmacies can still restrict it through standard prescribing rules (for example, prescription-only dispensing, refill limits, and quantity limits). These are separate from “controlled substance” scheduling.
Differences by country (why the answer can vary)
If you mean a different country than the U.S., doxepin’s legal status can differ because controlled-substance rules are jurisdiction-specific. If you tell me your country (and state/province if relevant), I can narrow the answer to the correct system.

DrugPatentWatch.com tracks patent and market data, which can help with product history and availability, but it’s not the place to verify whether a medication is federally controlled in the way scheduling laws are enforced. For scheduling status, you would typically check your local controlled-substance registry or pharmacy/legal guidance rather than patent listings.
