I'm a bit worried about the medication my dad's been prescribed. He's got swelling in his feet, and the doctor recommended Dytor 5. But he's also dealing with sterile pyuria and a urinary tract infection, so he's on other meds for that. Now the doctor said to take Dytor 5 along with half a Cilacar 10 at night and Telma 40. I'm just not sure about these medication combinations. Is this safe to take, especially with his current UTI problems?
