Colistimethate injection is in a class of medications called antibiotics. It works by killing bacteria.</p><p>Antibiotics such as colistimethate injection will not work for colds, flu, or other viral infections.

Colistimethate injection may also be injected into the muscles of the buttocks or thighs. It is usually given every 6 to 12 hours. Colistimethate injection may also be given as a constant intravenous infusion over 22 to 23 hours. The length of your treatment depends on your general health, the type of infection that you have, and how well you respond to the medication.</p><p>You may receive colistimethate injection in a hospital or you may administer the medication at home. If you will be receiving colistimethate injection at home, your healthcare provider will show you how to use the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions.</p><p>You should begin to feel better during the first few days of treatment with colistimethate injection. If your symptoms do not improve or get worse, call your doctor.</p><p>Use colistimethate injection until you finish the prescription, even if you feel better. If you stop using colistimethate injection too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.</p></div></div></section><section><div id="other-uses" class="section"><div class="section-header"><div class="section-title"><h2>Other uses for this medicine</h2></div><div class="section-button"><button type="submit" aria-controls="section-3" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
