Taking Vyvanse (lisdexamfetamine) without eating food can lead to stomach discomfort or upset for several reasons:
Irritation of the Stomach Lining: Vyvanse is a stimulant medication that can irritate the lining of the stomach, especially when taken on an empty stomach. This irritation can lead to feelings of nausea, discomfort, or pain.
Increased Acid Production: Stimulant medications like Vyvanse can increase the production of stomach acid, which can cause digestive discomfort when there's no food to help buffer the acid.
Delayed Gastric Emptying: Some stimulant medications can slow down the emptying of the stomach contents into the small intestine. This delay can cause a feeling of fullness or bloating.
Dehydration: Stimulant medications may reduce appetite, leading to reduced food and fluid intake, which can contribute to dehydration and digestive discomfort.
What you can do:
Eat a Light Meal: If you haven't eaten yet, try to have a light, balanced meal. Choose foods that are easy on the stomach, such as bananas, oatmeal, yogurt, or toast.
Stay Hydrated: Drink plenty of water throughout the day to stay hydrated. Dehydration can worsen stomach discomfort.
Avoid Caffeine and Acidic Foods: While experiencing stomach discomfort, it's best to avoid caffeine and acidic foods (like citrus fruits or tomatoes) as they may further irritate the stomach.
Rest and Relax: Sometimes, stomach discomfort can be worsened by stress or anxiety. Find a quiet place to rest and relax if possible.
Contact Your Healthcare Provider: If the discomfort persists or becomes severe, contact your healthcare provider or the prescribing doctor. They can provide further guidance and advice tailored to your specific situation.
Adjust Your Medication Schedule: If you find that taking Vyvanse on an empty stomach consistently causes discomfort, consider adjusting your medication schedule to take it after a meal.
Always follow your doctor's instructions regarding medication usage and consult them if you have any concerns about side effects or interactions. If you experience severe stomach pain, chest pain, or any other concerning symptoms, seek immediate medical attention.
