Check with your doctor if you have questions.
• Take Dynacin with a full glass of water (8 oz/240 mL). Do not lie down for 30 minutes after taking Dynacin .
• To clear up your infection completely, take Dynacin for the full course of treatment. Keep taking it even if you feel better in a few days.
• Dynacin works best if it is taken at the same time each day.
• If you miss a dose of Dynacin , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
