I went to a clinic five days ago with very raw, swollen throat and respiratory symptoms, was told it was probably virus, a cold, take Mucenix. Also given a prescription for doxycycline hyclate 100 to hold in case I didn t get better. Very little mucus, not much better, but I am now barking like a dog. Not an abuser of antibiotics, only once in the last 25 years, but ready to head for pharmacy! Yes?
