In cases of moderate to severe acne which, in the judgement of the clinician, require long-term treatment, the recommended initial dosage is 1 gram daily in divided doses.

In some patients it may be possible to maintain adequate remission of lesions with alternate day or intermittent therapy. Achromycin V (Tetracycline HCl Capsules, USP) therapy of acne should augment the other standard measures known to be of value. Duration of long-term treatment which can safely be recommended has not been established (see WARNINGS and Carcinogenesis, Mutagenesis, Impairment of Fertility).
