something similar happened to us and I called the pharmacy - the manufacturer does state 24 hours at room temp is ok, so as long as you were under 24 hours you should be just fine.
On another occasion, the mail order pharmacy did not correctly package the pulmozyme and I was concerned it had gotten warm - the pharmacy said that if I insisted they would reship the order but after discussing it with the pharmacist and the company rep I felt comfortable with keeping it (because of the time line of how long FedEx had the package and the weather at the time - It was far less than 24 hours and the weather was not hot)
