What is the appropriate timeframe to wait before seeking medical attention for a 24-year-old female experiencing abdominal pain, nausea, vomiting, and dehydration after alcohol consumption while taking Vyvanse (lisdexamfetamine)?

From the Guidelines

Seek medical attention immediately if vomiting persists for more than 24 hours or if you experience severe abdominal pain, signs of dehydration, or bloody vomit, as these symptoms can indicate severe alcohol withdrawal syndrome or other serious conditions that require prompt medical attention. In the meantime:

• Stop taking Vyvanse temporarily
• Stay hydrated with small sips of water or clear fluids
• Try bland foods like crackers or toast once vomiting subsides
• Avoid alcohol and caffeine Vyvanse (lisdexamfetamine) can cause stomach upset, which may be exacerbated by alcohol consumption, as noted in the management of alcohol-related liver disease guidelines 1. The combination can lead to dehydration and electrolyte imbalances if vomiting persists. Prolonged vomiting can also damage the esophagus and increase the risk of aspiration. If symptoms improve within 24 hours, consult your doctor before resuming Vyvanse, as they may recommend adjusting your dosage or timing of medication to reduce side effects. The Clinical Institute Withdrawal Assessment for Alcohol (CIWA) is known to be helpful for evaluating the severity of alcohol withdrawal syndrome (AWS), but high scores may be seen in psychiatric conditions that are similar to AWS, such as anxiolytic withdrawal, anxiety disorder, and physical conditions such as sepsis, hepatic encephalopathy, and severe pain 1. Given the potential for severe complications, including delirium tremens, seizures, and death, it is crucial to seek medical attention promptly if symptoms worsen or do not improve with self-care measures. The management of severe alcoholic hepatitis involves the use of corticosteroids, such as methylprednisolone, and the calculation of the Lille score to assess therapeutic response 1. However, in the context of acute alcohol withdrawal and potential interactions with Vyvanse, the primary concern is the immediate management of symptoms and prevention of further complications.

The most recent and highest quality study, published in 2022, emphasizes the importance of early identification and management of patients with severe alcoholic hepatitis, as well as the need for a comprehensive approach to address addiction and prevent relapse 1. This study highlights the importance of using the Lille score and MELD score to evaluate the severity of alcoholic hepatitis and predict short- and medium-term risk of death. However, in the context of this patient's symptoms, the primary concern is the immediate management of acute alcohol withdrawal and potential interactions with Vyvanse, rather than the long-term management of alcoholic hepatitis.

Therefore, the priority is to seek medical attention immediately if symptoms worsen or do not improve with self-care measures, and to follow the guidance of a healthcare professional for the management of Vyvanse and alcohol withdrawal symptoms.

From the Research

Abdominal Pain, Nausea, Vomiting, and Dehydration after Alcohol Consumption while taking Vyvanse

• The provided studies do not directly address the appropriate timeframe to wait before seeking medical attention for a 24-year-old female experiencing abdominal pain, nausea, vomiting, and dehydration after alcohol consumption while taking Vyvanse (lisdexamfetamine) 2, 3, 4, 5, 6.
• However, study 3 mentions that hyper- and hypokalemia usually develop within days or even weeks and should not be corrected within a few hours, indicating that electrolyte imbalances can take time to develop.
• Study 6 reports that the mean days to readmission for dehydration was 11.6 days, suggesting that dehydration can occur several days after the initial incident.
• Study 4 emphasizes the importance of prompt treatment for acute hyponatraemia, which can lead to cerebral oedema and other complications, indicating that severe symptoms should be addressed immediately.
• Study 5 highlights the significance of electrolyte disorders in patients with chronic diseases, including those taking certain medications, and notes that patients with uncontrolled blood glucose and those consuming alcohol are at higher risk of electrolyte disorders.

Factors Associated with Dehydration and Electrolyte Disorders

• Older age, male sex, history of ileostomy, high ileostomy output, and discharge creatinine >1.0 are associated with 30-day readmission with dehydration 6.
• No formal education, taking diuretic, taking anti-diabetic medication, body mass index ≥30 kg/m2, and uncontrolled blood glucose are factors associated with electrolyte disorders among patients with chronic diseases 5.
• Alcohol consumption is also a risk factor for electrolyte disorders 5.

Seeking Medical Attention

• Given the potential risks and complications associated with dehydration and electrolyte disorders, it is essential to seek medical attention if symptoms persist or worsen over time 3, 4, 5, 6.
• The exact timeframe for seeking medical attention may depend on the severity of symptoms and individual factors, such as underlying medical conditions and medication use 2, 3, 4, 5, 6.
