Following a single 150 mg IM dose of DEPO-PROVERA Contraceptive Injection, medroxyprogesterone acetate concentrations, measured by an extracted radioimmunoassay procedure, increase for approximately 3 weeks to reach peak plasma concentrations of 1 to 7 ng/mL.
Deafness can increase until it is almost impossible to hear any sound, but it has been found that most deaf persons can hear at least one sound. If a person is totally deaf, he cannot hear a thing including his own voice. Some people are born deaf, and some lose their hearing from disease or other causes. Most hearing problems are caused by diseases that do not necessarily start in the ear but reach it from some other part of the body.
The severely deaf rely primarily on lip-reading, even with a hearing aid. Profoundly deaf people may communicate by lip-reading, and Sign Language may be their first or preferred language. Hearing loss occurs primarily when the inner ear or auditory nerve is damaged or when sound waves cannot reach the inner ear.
