Special information if you are pregnant or breastfeeding

The effects of Lanoxin during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, inform your doctor immediately. Lanoxin appears in breast milk and could affect a nursing infant. If this medication is essential to your health, your doctor may advise you to discontinue breastfeeding.

Recommended dosage for Lanoxin

Your doctor will determine your dosage based on several factors: (1) the disease being treated; (2) your body weight; (3) your kidney function; (4) your age; and (5) other diseases you have or drugs you are taking.

If you are receiving Lanoxin for the first time, you may be rapidly "digitalized" (a larger first dose may be taken, followed by smaller maintenance doses), or gradually "digitalized" (maintenance doses only), depending on your doctor's recommendation.

ADULTS

If your doctor feels you need rapid digitalization, your first few doses may be given intravenously. You'll then be switched to tablets or capsules for long-term maintenance. A typical maintenance dose might be a 0.125 milligram or 0.25 milligram tablet once daily, but individual requirements vary widely. The exact dose will be determined by your doctor, based on your needs.
