Signs And Symptoms
May vary from CNS depression to stimulation (restlessness to convulsions). Antihistamine overdosage in young children may lead to convulsions and death. Atropine-like signs and symptoms may be prominent. Dextromethorphan may produce central excitement and mental confusion. Very high doses of dextromethorphan may produce respiratory depression.
Induce vomiting if it has not occurred spontaneously. Precautions must be taken against aspiration especially in infants, children, and comatose patients. If gastric lavage is indicated, isotonic or half-isotonic saline solution is preferred. Stimulants should not be used. If hypotension is a problem, vasopressor agents may be considered.
Deconsal® DM (phenylephrine, pyrilamine maleate, and dextromethorphan hbr) Tannate Chewable Tablets are contraindicated in patients sensitive to any of the ingredients or related compounds. Antihistamines are contraindicated for use in the treatment of lower respiratory tract symptoms, including asthma. Phenylephrine is contraindicated in patients with hypertension or with peripheral vascular insufficiency (ischemia may result with risk of gangrene or thrombosis of compromised vascular beds).
Deconsal® DM (phenylephrine, pyrilamine maleate, and dextromethorphan hbr) Tannate Chewable Tablets should not be used in patients receiving a monoamine oxidase inhibitor (MAOI) (see "PRECAUTIONS-DRUG INTERACTIONS").This monograph has been modified to include the generic and brand name in many instances.
