Forgetting to take doses of anxiety medication can have varying effects from person to person. Some individuals may not notice any difference when they miss a dose, while others may experience symptoms such as heart palpitations, headaches, and dizziness. It is important to be consistent with medication to avoid potential side effects or withdrawal symptoms. Consistently skipping doses could also lead to a decrease in the overall effectiveness of the medication over time. If you have any concerns or questions about your medication regimen, it is best to consult with your healthcare provider.
