Thank you, thank you very much. You confirmed the results of my Internet research. The 'giveaway' here is the LA, which means long acting - basically, time released. My husband was given this drug years ago for chronic sinusitis and it worked great. He quit taking it (for various reasons), but has recently asked his new doctor to prescribe it again (what the doctor has given him just isn't working). However, the doctor is the one asking for what dosage he took. We told him "LA" - but the doc doesn't realize the LA tells the dosage! Thanks again.
