minoxidil ↔ tamsulosin
Applies to:minoxidil topical and Flomax (tamsulosin)
MONITOR: Theoretically, topical administration of minoxidil may potentiate the hypotensive effects of systemic minoxidil and other vasodilators. Although systemic absorption of topical minoxidil is generally minimal (approximately 1.6% to 3.9% of an applied dose), adverse cardiovascular effects such as edema, palpitations, blood pressure decreases, and increased pulse rate have been reported in a few patients. Increased systemic absorption may occur when topical minoxidil is used in excess of normally recommended dosages or applied to compromised skin.
MANAGEMENT: Patients prescribed topical minoxidil in combination with systemic vasodilators or peripherally-acting antiadrenergic agents should be monitored for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache.

The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
