Atomoxetine 40mg, like other medications, can cause side effects. Common ones include decreased appetite, resulting in weight loss; difficulty sleeping (insomnia); stomach upset, possibly manifesting as nausea or vomiting; and headache. These usually lessen over time as your body adjusts.
Less common, but still possible, side effects include increased heart rate or blood pressure. Regular monitoring by your doctor is advisable to check for these. You may also experience dizziness or lightheadedness. Changes in mood, such as increased anxiety or irritability, are also reported.
Serious, though rare, side effects include allergic reactions (rashes, itching, swelling), seizures, and liver problems. Seek immediate medical attention if you experience any of these.
