Can tamsulosin cause problems?
Along with their useful effects all medicines can cause unwanted side effects, which usually improve as your body adjusts to the new medicine. Speak with your doctor or pharmacist if any of the following side effects continue or become troublesome.
| Common side-effects - these affect less than 1 in 10 people who take this medicine | What can I do if I experience this |
| Dizziness, drowsiness, lightheadedness or fainting (especially when getting up from a lying or sitting position) | Getting up slowly may help. If you begin to feel dizzy, lie down so that you do not faint, then sit for a few moments before standing to prevent the dizziness returning |
| Dry mouth | Try chewing sugar-free gum, sucking sugar-free sweets or pieces of ice |
| Drowsiness | Make sure your reactions are normal before driving, operating machinery or doing any other jobs which could be dangerous if you were not fully alert |
| Headache | Ask your pharmacist to recommend a suitable pain-killer. If the headache continues, speak with your doctor |
Other side-effects include weakness, depression, sexual problems, feeling or being sick, diarrhoea, constipation, blurred vision, stuffy nose, fast or fluttering heartbeat, rash, itching, or flushing.
