How to take Foundayo<\/span><\/h2>\n

Foundayo is an oral tablet that’s taken once per day with or without food. The tablets should be swallowed whole and never split, crushed, or chewed.<\/span><\/p>\n

To reduce the risk of side effects, Foundayo is started at a low dose that’s gradually increased over several months. Your healthcare provider will typically follow this schedule, increasing the dose after at least 30 days at each step:<\/span><\/p>\n
