How to use

Here are some general guidelines on how to use Lanoxin:

  1. Follow the Prescribed Dosage: The dosage will be determined based on your individual condition, medical history, and response to the medication.
  2. Take with or without Food: Lanoxin can be taken with or without food. If you experience stomach upset, taking it with a meal or snack may help alleviate any discomfort.
  3. Use a Measuring Device: If you are using the oral solution form of Lanoxin, use a measuring device such as an oral syringe or dosing spoon to measure the prescribed amount accurately. Do not use a regular household teaspoon as it may not provide the correct dose.
  4. Regular Monitoring: Your healthcare provider may order periodic blood tests to measure the levels of digoxin in your blood and assess the response to treatment. It is important to attend these appointments as scheduled.
  5. Do Not Miss Doses: Take Lanoxin consistently at the same time(s) each day to maintain a steady level of the medication in your body. If you accidentally miss a dose, take it as soon as you remember, unless it is close to the time for your next scheduled dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one.
  6. Keep Track of Medications: Certain medications can increase the levels of digoxin in the blood, leading to potential side effects.


The following are general dosage guidelines for Lanoxin:

  1. Initial Dose: The initial dose of Lanoxin may vary depending on the condition being treated. Typically, for heart failure, the starting dose is usually lower and gradually increased over time. For irregular heart rhythms, the initial dose may be higher.

  3. Pediatric Dosage: The dosage of Digoxin for children is determined based on their weight and condition. It is essential to follow the prescribed dosage for pediatric patients and ensure proper monitoring.
  4. Elderly or Renally Impaired Patients: Elderly individuals or those with impaired kidney function may require adjusted dosages of Lanoxin.

An overdose of Digoxin can be dangerous and potentially life-threatening. If you suspect an overdose or have taken more Lanoxin than prescribed, seek immediate medical attention or contact your local poison control center. Here are some important points regarding overdose:

  1. Recognize the Symptoms: Overdose symptoms of Lanoxin may include severe dizziness, fainting, rapid or irregular heartbeat, vision changes (such as blurred or yellow-tinted vision), confusion, nausea, vomiting, diarrhea, and loss of appetite. However, symptoms can vary among individuals.
