Hold tobramycin and restart at a lower dose/ frequency.
Increase tobramycin frequency but keep dose the same.
Continue tobramycin at the same dose and frequency.
Discontinue tobramycin and start amikacin.
Discontinue tobramycin and start ciprofloxacin

Aspirin is used to prevent further infarcts in persons who have had 1 or more myocardial infarcts and may also reduce the incidence of first infarcts.
Aspirin is used extensively to prevent transient ischemic attacks (TIAs), ischemic stroke and other thrombotic events.
Abciximab, Tirofiban and Eptifibatide are indicated for unstable angina and non-Q-wave acute MI
Clopidogrel and Ticlopidine are effective in preventing TIAs and ischemic strokes, especially in patients who cannot tolerate aspirin.
Clopidogrel is routinely used to prevent Thrombosis in patients who have not received a coronary artery stent.
Dipyridamole is approved as an adjunct to heparin in the prevention of thrombosis in those with cardiac valve replacement.
