Unpleasant side effect symptoms and conditions

I'm taking this for bronchitis, I have COPD and have frequent bouts with bronchitis. I was told no dairy products with this medication and to only take with a meal ... my only problem has been urinary leakage while sleeping. It's like I took a very strong water pill and every move in my sleep causes some wetness. I've had to wear pads since I started taking the medication, most uncomfortable. No nausea, no problems in the sun, but I was told it will make skin more sensitive to the sun's rays. It's possible that my pharmacist was more thorough and so I followed his suggestions, because the only unpleasant side effect has been the urinary problem.
