Atomoxetine Side Effects
There are a number of less common but more serious side effects with atomoxetine that you should report to your healthcare provider. These side effects include but are not limited to:
- Lightheadedness, dizziness, or fainting
- A painful erection of the penis that does not go away (priapism) (see Strattera Sexual Side Effects)
- Suicidal thoughts
- Chest tightness, chest pain, or heart palpitations
- Shortness of breath
- Behavior that is more outgoing or aggressive than normal
- Strange behavior, agitation, or restlessness
- Hallucinations (seeing, hearing, or feeling things that are not really there)
- Signs of liver damage, including yellow eyes or skin, pain near your liver (right upper abdomen), and unusually dark urine
- Signs of an allergic reaction, including an unexplained skin rash; itching; hives; wheezing or trouble breathing; or unexplained swelling.
You may experience some or none of the atomoxetine side effects explained above. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried. Therefore, be sure to let your healthcare provider know if you develop any side effects, or anything that "just does not seem right," while taking atomoxetine. While it may not be an atomoxetine side effect, your healthcare provider will be able to diagnose and treat the problem.
