Z pack (zithromax) 5, 3, and 1 day dose???

Question

My doctor just prescribed me zithromax for ear and throat infection. In the past it was always a 5 day coarse with double dose on the first day. He told me there is also a 3 day and a single dose option. My question is what is the difference? If there is a single dose option why offer the 3 and the 5. I'm taking the 3 day dose this time which is 500mg for 3 days opposed to the usual 500 the first day then 250 for four days. Just seems strange the same medication would have 3 different options to get you the same effect.

Also what is the truth about antibiotics and alcohol? Is it an old wives tale or is it true that alcohol cancels out the z pack? (serious answers only please)..

Really 2 questions but thanks!!!

The different dosage packs are used because each regimen is used for overlapping but somewhat different indications or types of infections. There are some in which a single dosage will suffice (at 500 mg or higher) others that do well on a lower dosage per day (after a loading dose the first day.
There is no available definitive information to my knowledge that suggests that Alcohol should be avoided while taking Zithromax but the suggestion is that because of the hepatic metabolic type it might be wise not to stress the liver too much. The same goes for any general statements as you've included about antibiotics in tota. Should alcohol be avoided? Yes. Is it detrimental, probably not in moderation.
