Not really: This is not a situation that will lead to serious toxicity. She may have trouble sleeping and feel "spacey". Please have her consult with you before taking any medication, including OTC medications. She has taken more than twice the recommended dose of Pseudephedrine and combined with Phenylephrine will have some minor side effects. ...Read more
