apfootball35, here's what i can tell you about Doxycycline.
This is the holy grail for acne.
I'm 35 and started to get horrible acne on my back and some acne on my face.
I tried a few products.
I first tried the clindamycin medicated pads.
This was the worst product.
It like burned my face. It made my acne worse.
Then I tried Proactiv with the benzoyl peroxide.
My body just does not react well to benzoyl peroxide.
I was breaking out more using the Proactiv.
Then my derm recommended I try Doxycycline.
It was 100 MG.
I took one pill a day.
Within 3 weeks my acne was gone.
Let me tell you, I had some really bad acne on my shoulders.
The Doxycycline just was amazing.
Now, the first 3 days I took Doxycycline I did get a bad stomach ache.
You might even feel nauseas.
I would recommend the first week you take Doxycycline not to take it on an empty stomach.
Just let your body get used to it.
After the first week you can take it without food.
Just stick with the Doxycycline.
Its amazing.
Now about this information it causes kidney damage.
That is totally false.
Just remember, only take the Doxycycline when you have acne.
Once your cleared, dont keep taking the Doxycycline.
Only take it when you start breaking out.
Also, the same company that makes Doxycycline makes Minocycyline and Tetracycline
