SOLODYN is indicated to treat only inflammatory lesions of non-nodular moderate to severe acne vulgaris in patients 12 years of age and older.
Limitations of Use
SOLODYN did not demonstrate any effect on non-inflammatory acne lesions. Safety of SOLODYN has not been established beyond 12 weeks of use. This formulation of minocycline has not been evaluated in the treatment of infections [see Clinical Studies].
To reduce the development of drug-resistant bacteria as well as to maintain the effectiveness of other antibacterial drugs, SOLODYN should be used only as indicated [see WARNINGS AND PRECAUTIONS].
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug, and may not reflect the rates observed in practice.
The following table summarizes selected adverse reactions reported in clinical trials at a rate of ≥ 1% for SOLODYN.

Advice to Patients
Advise patients that antibacterials (including minocycline) should only be used to treat bacterial infections and not used to treat viral infections (e.g., the common cold).c 116
Importance of completing full course of therapy, even if feeling better after a few days.c 116
Advise patients that skipping doses or not completing the full course of therapy may decrease effectiveness and increase the likelihood that bacteria will develop resistance and will not be treatable with minocycline or other antibacterials in the future.c 116
Importance of drinking sufficient quantities of fluids when taking capsules or tablets to reduce the risk of esophageal irritation and ulceration.a
Advise patients that absorption of some minocycline preparations may be reduced when taken with foods, especially those containing calcium, and that pellet-filled capsules or tablets should be taken at least 1 hour before or 2 hours after meals and/or milk.c 116
Advise patients that adverse CNS effects (light-headedness, dizziness, vertigo) may occur and caution should be used when driving vehicles or operating hazardous machinery.100 105
Advise patients to avoid excessive sunlight or artificial UV light and to discontinue the drug at the first sign of skin erythema;a c 116 consider use of sunscreen or sunblock.a
Advise patients that minocycline may decrease effectiveness of oral contraceptives and that alternative nonhormonal contraceptive measures should be used.a
Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.c 116 (See Fetal/Neonatal Morbidity under Cautions.)
Importance of informing clinicians of existing or contemplated therapy, including prescription and OTC drugs.c 116
Importance of informing patients of other important precautionary information. (See Cautions.)
