Fluid in Lungs

I wrote my cardiologist a letter about a problem a MONTH ago- no answer. I called his office today- he called at 9:30 pm and I missed it.  I really need some advice.  Twice in the last 6 mos I've missed my dose (75mg) of Toprol  by 5 hours .   I developed very noisy lungs---like the times I had pneumonia.  My husband could hear it WITHOUT even needing a stethoscope.  While I have seldom missed my med, it happens.....What is this happening? Should I worry?  Does this mean I have CHF?  
Thank you!
P.S.   An hour after remembering the Toprol the lungs completely clear.

It would be very difficult (actually impossible) to be able to say what you have been experiencing.  Toprol (metoprol XL) is a beta blocker which is prescribed in a number of different situations (heart failure, arrhtyhmias, high blood pressure, etc).  Without knowing your medical history and being able to perform a physical examination, there is no way of knowing for sure what is going on.  However, Toprol is a long-acting beta blocker, so even missing a dose for 5 hours, should theoretically not bring the acute onset of any symptoms.  If you are experiencing significant symptoms such as shortness of breath, chest pain, light-headedness, dizziness, or syncope (fainting) -- then I would be concerned enough that you should seek further evaluation. Otherwise, I think it is safe to follow-up with your regular cardiologist when he/she is available.
