Inform your doctor about all other medications you are taking before using Modalert 200, especially if you have a history of drug abuse or are taking any for depression or anxiety. Avoid driving or using machinery until you know how the medication affects you because it may cause you to feel lightheaded. Additionally, it may interfere with some forms of birth control. While you are taking it and for one month after, use a different method of birth control. Hormonal birth control pills, patches, rings, injections, and implants may become less effective when taken with the drug. Antidepressants, monoamine oxidize inhibitors like isocarboxazid, phenelzine, and tranylcypromine, as well as selective serotonin reuptake inhibitors like Citalopram may also interact with it.
