Does the freezer keep 10 mg tadalafil stronger?

Reply from our reviewer

If the blister sat at 28 C, is the 10 mg still the labelled start?

Reply from our reviewer

Excursions permitted to 15 to 30 C (59 to 86 F) appear on the U.S. Cialis carton. 28 C sits inside that excursion band. The recommended starting dose of tadalafil for use as needed remains 10 mg. The dose may be increased to 20 mg or decreased to 5 mg. Tadalafil for use as needed was shown to improve erectile function compared to placebo up to 36 hours following dosing.
