Understanding Changes in Vyvanse Effectiveness After Long-Term Use
I have been using Vyvanse for a significant period now, and typically, the side effects I experience have been quite mild. They include some anxiety, a touch of nausea, feelings of discomfort, and occasional heart palpitations. Recently, however, I’ve noticed that these side effects seem to have intensified. This change is puzzling, considering that I've maintained the same dosage for many years. The only notable alteration in my life is a considerable weight loss; I’m curious if that might be influencing how the medication affects me.

It's understandable to feel concerned about changes in the effectiveness and side effects of Vyvanse, especially after long-term use. Changes in side effects can happen for various reasons, including weight loss. Here’s a clearer breakdown of your situation and next steps.
Main Points
- Side effects like increased anxiety, nausea, discomfort, and heart palpitations can occur if there are changes in your body, such as weight loss.
- Long-term use of Vyvanse might lead to the body adapting to the medication, which could affect how you respond to it.
Explanation
Vyvanse (lisdexamfetamine) is a stimulant medication often prescribed for ADHD. Your body may respond differently due to weight loss, which can alter how the medication is metabolized. When you lose weight, the concentration of the medication in your system can increase, potentially intensifying side effects. Additionally, long-term use may lead to tolerance, where the medication appears less effective or side effects become more pronounced.
Next Steps
-
Monitor Your Symptoms: Keep track of your side effects and any changes in their intensity. Note when they occur and if any particular triggers seem to worsen them.
-
Assess Lifestyle Changes: Reflect on other factors in your life that may be contributing to these changes, such as stress, sleep quality, or dietary changes, and make adjustments where necessary.
-
Stay Hydrated and Eat Well: Maintain good nutrition and hydration. This helps ensure your body can metabolize the medication effectively and supports overall health.
-
Practice Stress Management: Engage in activities that help reduce anxiety, such as deep breathing exercises, meditation, or light physical activity.
-
Consider Re-evaluating Dosage: If symptoms persist or worsen, it may be worth discussing with your healthcare provider the possibility of adjusting your dosage, or even switching medications.
-
Avoid Abrupt Changes: If you want to adjust your medication, always do so under a healthcare professional's guidance to prevent withdrawal symptoms or other complications.
If the side effects become significantly concerning, or if you experience any severe symptoms, make sure to prioritize seeking professional advice. You’re taking a good first step by being aware and proactive about your health. Let me know if you need more details or have other questions!

Possible Rabies Concern?
For the past week, I've been experiencing unusual sounds during the early hours and occasionally in the evenings. It resembles the squeaking of a dog toy, typically occurring in groups of three, and I'm at a loss as to the source of these noises. Over the weekend, I visited a friend's house, and upon returning home late last night, I didn’t hear the squeaks. However, around 11 PM, while I was lounging in bed, I felt a sudden but not painful jab on the lower right side of my neck. I quickly scanned the room for any sign of a bat, but found nothing, which left me feeling uneasy. The area where I felt the jab developed a small red bump that soon became warm and began to tingle. This sensation persisted for several hours until I finally fell asleep around 2 AM. When I woke up at 11 AM, the tingling was still there but noticeably less intense. My primary concern stems from a small hole in my wall, about the size of a dime and a pencil's length deep; it was created when I punched it as a child and has never been fully repaired. Next to it, I noticed a light yellowish-brown stain. At the time of the incident, my room was well-lit, which makes me consider other potential explanations for the sensation. One possibility is a nerve issue; though I haven't had any official diagnoses, my nerves have been acting strangely lately, with the opposite side of my neck feeling tingling and sore, albeit without the same sudden impact I felt initially. Additionally, there was an unfamiliar small insect in my room that I had never noticed before. It was brown, relatively fast-flying, and kept colliding with the walls, creating a lot of noise. I’m uncertain if it could be connected to my recent experiences. Overall, I’m quite concerned about the potential implications of these strange occurrences, particularly with rabies being a possibility. I’m contemplating whether I should seek professional advice or take any precautions, given the circumstances.
Is It Time to See a Doctor?
Greetings, I am a 20-year-old male, weighing 90 kg and standing 5'11" tall. I occasionally use 100 mg of sumatriptan as needed and do not smoke. I am reaching out to determine whether I should consult a healthcare professional regarding some concerning health issues. Recently, I've noticed unusual symptoms with my eyes—specifically, my pupils have been excessively dilated and do not seem to respond normally to changes in light. Even in bright conditions, people often ask me if I am under the influence, as my irises can become nearly invisible due to the dilation. Looking at my health history, I have been suffering from migraines for approximately 11 years. I've also battled persistent back pain, predominantly in the thoracic and lumbar areas, for the last 5 years, which significantly disrupts my daily activities. Furthermore, I've experienced eating disorders, balance problems, and profound feelings of depression. Self-harm and generalized anxiety have also troubled me, alongside sleep difficulties. I tend to be forgetful and frequently misplace items, a concern I'm currently having assessed as I await an evaluation for Autism Spectrum Disorder, which may shed light on my memory issues. Adding to this, I endure intense mood swings and episodes of dissociation, and I frequently feel nauseated, especially following any illness, even something as minor as a cold. I've been told that I sometimes do not appear to be myself. That summarizes my situation. I apologize for the lengthy message.
