Welcome to HCM.
You developed acne vulgaris
You got good response in past,by minocycline
for acne vulgaris.
Definitely you can repeat the medicines.
But, you have to be aware of toxicity of isotretinoin .
You should avoid isotretinoin if you are married and going to conceive .
If you are not going to be pregnant in near future, you can take isotretinoin.
I hope you got my answer.
