Because the " infectious dose " for some pathogens can be very small ( 10-100 viable units, or even less for some viruses ), and infection can result from direct transfer from surfaces via hands or food to the mouth, nasal mucosa or the eye, ' hygienic cleaning ' procedures should be sufficient to eliminate pathogens from critical surfaces.

Because of its high potency, the smallest lorazepam tablet strength of 0. 5 mg is also a significant dose reduction ( in the UK, the smallest tablet strength is 1. 0 mg, which further accentuates this difficulty ).

Because of this, less medication is needed for an effective dose to reach the lungs, and there are fewer side effects from corticosteroid residue in the mouth.

Because it may be used in topical creams with a concentration as much as 20 %, it is not difficult to administer a dose sufficient to cause this problem.

Because the RfD assumes " a dose below below which no adverse noncarcinogenic health effects should result from a lifetime of exposure ", the critical step in all chemical risk and regulatory threshold calculations is dependent upon a properly derived dose at which no observed adverse effects ( NOEAL ) were seen which is then divided by an uncertainty factor that considers inadequacies of the study, animal-to-human extrapolation, sensitive sub-populations, and inadequacies of the database.

Because phages replicate in vivo, a smaller effective dose can be used.

Because of the significant side effects of long-term high – dose prednisone use, the starting dose is tapered over several weeks to a dose that the physician feels is tolerable for the patient.
