A 40-year old female suffered from an episodic illness of 7 years and was diagnosed as recurrent depressive disorder. After 15 days of fluoxetine 40 mg and amitriptyline 25 mg, she reported heaviness in breasts and increased breast size with creamy white discharge. Serum PRL level was raised (333 ng/ml). Hence, she was switched to sertraline, and after 1 month, breast secretions stopped completely with normal PRL. Due to relapse in depressive symptoms, she was switched back to fluoxetine as a single agent, and dose was gradually hiked to 60 mg. Now, she is asymptomatic for the past 15 months.
A 34-year-old female patient was admitted to our clinic with complaints of anhedonia, decreased appetite, loss of sexual desire, irritability and passive suicidal thoughts. These complaints had lasted about two months. The patient was considered to have major depressive disorder, so we initiated venlafaxine, 75 mg/day. Six months after this initiation, we increased the dose of venlafaxine to 150 mg, because the patient was not admitted to the clinic regularly.\nThree months later (the ninth month of treatment), we increased the venlafaxine dose to 225 mg/day. The patient started to experience galactorrhea while she was taking 150 mg/day, but she did not inform us about this side effect during our examination, so we increased the dose of venlafaxine. Ten days after taking venlafaxine at a dose of 225 mg/day, the patient was admitted to our clinic again for galactorrhea that was so severe she could not endure it anymore. Brain magnetic resonance imaging was performed for her pituitary tumor, but the result was normal. We checked her hormone levels: FSH, LH, T3, T4 and TSH were within the normal range; however, her prolactin level was 156 ng/ml. We considered the galactorrhea and the increased prolactin levels were a result of venlafaxine the patient had been taking. Consequently, we decreased the venlafaxine dose to 150 mg/day.\nOne month later, although her prolactin level had decreased to 9 ng/ml, the galactorrhea persisted. So we decreased the venlafaxine dose to 75 mg/day. At the patient’s next visit, she stated that while she was taking 75 mg/day, the galactorrhea symptoms had been significantly relieved, but she felt worse, so she started to take 150 mg/day again, which once more caused a severe case of galactorrhea. We decreased the dose of venlafaxine to 75 mg/day; afterwards, we switched the patient to escitalopram 10 mg/day, and lorazepam 2 mg/day. One month later, we increased the escitalopram dose to 20 mg/day, and over the course of the following four weeks, we tapered the lorazepam dose. With a treatment of escitalopram 20 mg/day, the patient has reported that she is feeling very well; she was experiencing only minimal galactorrhea, but she chose to continue with escitalopram.
