vardenafil increases effects of nitroglycerin rectal by additive vasodilation. Either increases effects of the other by additive vasodilation. Coadministration of PDE-5 inhibitors (eg, avanafil, sildenafil, tadalafil, vardenafil) and guanylate cyclase stimulators (eg, riociguat) is contraindicated due to risk of additive hypotension. Either increases effects of the other by pharmacodynamic synergism. Coadministration of vericiguat with PDE-5 inhibitors may result in additive hypotensive effects.

Either increases effects of the other by QTc interval. Each drug prolongs the QTc interval, which may increased the risk of Torsade de pointes, other serious arryhthmias, and sudden death. If coadministration unavoidable, more frequent monitoring is recommended for such patients. alfuzosinvardenafil increases effects of alfuzosin by pharmacodynamic synergism. vardenafil increases effects of alfuzosin by pharmacodynamic synergism. Macimorelin causes an increase of ~11 msec in the corrected QT interval.
| Step | Action | Notes |
|---|---|---|
| Dose Administration | Oral, with water | Do not chew or crush |
| Timing before Activity | 30-60 minutes before sexual activity | Peak levels within this period |
| Food Intake | Can be taken with or without food | High-fat meals may delay absorption |
| Duration of Use | As prescribed, typically occasional | Avoid daily use unless instructed |
Avoid coadministration with drugs that prolong QT interval, which could increase risk for developing torsade de pointes-type ventricular tachycardia. Allow sufficient washout time of drugs that are known to prolong the QT interval before administering macimorelin.
