Osteoporosis is common in people with cystic fibrosis (a build-up of mucus in the lungs). This is due to poor absorption of fat, which leads to vitamin D deficiency. Calcitriol taken by mouth appears to increase calcium absorption.
Antibiotics such as penicillin and amoxicillin (Amoxil) are used for a variety of infections that may result after dental procedures. Erythromycin (Benzamycin, Emgel, Ery, Ilotycin, Staticin) is usually prescribed when patients have allergies to penicillin or amoxicillin (Amoxil).
Antibiotic drugs usually kill bacteria, but they are not effective against viruses. Infections caused by bacteria include strep throat, tuberculosis and urinary tract infections. Diseases caused by viruses include chickenpox, AIDS and common colds.
