Sodium Bicarbonate - Nuvigil (Armodafinil) Interaction

Interaction Details

Armodafinil is classified as belonging to the following category: Stimulant Laxatives

Theoretically, sodium bicarbonate may increase the risk of hypokalemia in patients taking stimulant laxatives.
Long-term use of stimulant laxatives, or acute use of high doses (e.g., in bowel-cleansing regimens), can result in potassium loss and hypokalemia. Orally, use of excessive sodium bicarbonate (such as intake of "tablespoons" of sodium bicarbonate daily or up to one box of baking soda weekly) has been associated with cases of hypokalemia. Furthermore, the most common complication of intravenous sodium bicarbonate is hypokalemia.

Armodafinil Overview

• Armodafinil is used to treat excessive sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness) or shift work sleep disorder (sleepiness during scheduled waking hours and difficulty falling asleep or staying asleep during scheduled sleeping hours in people who work at night or on rotating shifts). Armodafinil is also used along with breathing devices or other treatments to prevent excessive sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS; a sleep disorder in which the patient briefly stops breathing or breathes shallowly many times during sleep and therefore does not get enough restful sleep). Armodafinil is in a class of medications called wakefulness-promoting agents. It works by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness.
