I have some moderate acne on my back and shoulders. I was prescibed 100mg minocycline per day for one months and it has little to no affect. Aside from that, I also felt some side effects such as upset stomach and light-headedness, although these seemed to fade away towards the end of the month.

Now my doctor is prescribing me a double dose of mino (100mg twice a day) plus Stieva-A tretinoin cream for post-shower. I am a little nervous about taking a double dose of mino as I was already feeling side affects with the single dose. Do you think it's worth trying or should I try the tretinoin cream alone.

The doctor is from a walk-in clinic and not a skin expert in particular. Just wanted to see if anyone had a second opinion.

Thanks!
