Hi,
How are you? Can you elaborate on your headaches? It is good that you have your eyes checked recently by your eye doctor. If there were no previous trauma or underlying medical conditions, this could be due to primary headaches such as tension, cluster or migraine headaches. The usual side effects of Fluoxetine are: nausea, loss of appetite, diarrhea, dry mouth, trouble sleeping, dizziness, drowsiness, weakness, or sweating may occur. Unusual or severe mental/mood changes such as anxiety, weight loss, and vision changes may also be observed. If this headache persists, have this checked by your doctor or be referred to a neurologist for proper evaluation.Take care and regards.
