Placida (flupentixol/melitracen) is typically prescribed for short-term relief, as long-term use requires close medical monitoring. Regarding your bladder symptoms, this medication can sometimes cause difficulty urinating due to its mild anticholinergic effects. While mild hesitancy is common, severe or prolonged trouble emptying your bladder can cause urine to back up, which may eventually strain the kidneys. Fortunately, this is highly manageable when addressed early. Do consult your doctor. They can safely evaluate your symptoms, adjust your dosage, or discuss alternative treatments to ensure you stay comfortable and healthy.
