Q: What else should I know about taking Tequin?
A: When taking Tequin, it is recommended that you do not drive or operate dangerous machines until you know how Tequin affects you.

The manufacturers of pharmaceutical drugs can be held liable for any injuries caused by inadequate drug warnings or defects in the medications themselves.
