I'm on minocycline as well. I wouldn't be too afraid to give it a whirl. It's helped me. If you're worried about side affects, popping a pro-biotic can help, especially with digestion issues. It's not a long term fix usually... but hey, if we can get away with it and it helps, why not? Gives you a breather for topicals and lifestyle changes to kick in. Or even better, just for one's hormones to settle down on their own if that's the root cause for you.
Whatever you decide, good luck! :]
