Adderall tongue is a common side effect of Adderall that can detrimentally and seriously affect a person’s quality of life. To help relieve Adderall tongue stay well-hydrated. Adderall and other ADHD medications can cause dehydration, so you need to drink at least 6 to 8 glasses of fluid per day. Take frequent sips of water rather than drinking a whole glass of water at once. Use artificial saliva products (such as sprays or lozenges) – these can help moisten the tissue and last longer than water. There are many different brands of these available over the counter at drug stores and they can be used multiple times a day.

Avoid sucking candy that contains sugar because this will increase your risk of dental decay Continue reading
