Doxapram stimulates respiration. It may be used to start or stimulate respiration in newborn puppies and kittens following a difficult birth or a C-section. It may also be used during or after surgery, or to diagnose laryngeal paralysis. It is not a substitute for proper artificial respiratory support (mechanical ventilation). Doxapram may be given as drops under the tongue or by injection. The effect is usually seen within 2 minutes of giving the drug. At high or repeated doses may see high blood pressure, heart rhythm abnormalities, seizures, or hyperventilation. Consult your veterinarian if you notice any of these side effects.
