How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.

- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
Both of these medicines can lower your blood pressure, so taking them together may lower it more than either one alone. Asenapine (the Secuado patch) is used for certain mental health conditions, and atenolol (Tenormin) is a beta blocker that slows the heart and relaxes blood vessels. When your blood pressure drops too much, you might feel dizzy, lightheaded, or faint, especially when you stand up quickly.
The good news is this is expected and easy to keep an eye on. Please keep taking both exactly as prescribed. Your care team can check your blood pressure and fine-tune your doses if needed. Just let them know if you feel dizzy or faint.
Effect: Additive hypotensive effect from combining asenapine (transdermal) with the beta blocker atenolol.
- Mechanism: Pharmacodynamic (additive BP lowering); no prodrug activation involved for either agent.
- Direction: Increased risk of hypotension, including orthostatic symptoms.
- Onset/Evidence: Onset unspecified; evidence is theoretical.
- Severity: Moderate.
- Management: Monitor blood pressure (consider orthostatic measurements), watch for dizziness/syncope, and titrate/individualize doses as tolerated.
Exercise caution during initiation and dose changes of either drug.
