Lamotrigine is available in the following forms:

• Oral tablets (immediate-release)
  
• Chewable tablets
  
• Extended-release tablets
  
  

The typical starting dose of lamotrigine varies depending on the condition being treated, the severity of symptoms, and individual patient factors. It is crucial to follow your healthcare provider's instructions regarding dosage and administration.

For epilepsy, the typical starting dose can vary depending on the type of seizure being treated and whether the patient is taking other seizure medications.

For bipolar disorder:

• Immediate-release tablets: The typical starting dose is 25 mg once daily for two weeks, then increased to 50 mg once daily for two weeks. Adjustments can then be made based on clinical response.
  
  

The dosage may be adjusted based on the response and tolerance to the medication. Your healthcare provider will determine the most appropriate dose based on your medical history, current medications, and response to the medication.

Lamotrigine should be taken exactly as prescribed by your healthcare provider. Do not exceed the recommended dose or duration of treatment without consulting your provider.

If you have any questions about your dosage or need adjustments, contact your healthcare provider for guidance. If you want to talk to a provider right away, consider scheduling an online doctor appointment through a telehealth platform like Sesame.

If you miss a dose of lamotrigine, 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.

Maintain a consistent dosing schedule to ensure the effectiveness of lamotrigine in managing your condition.

Continue taking lamotrigine as prescribed by your healthcare provider, even if you start feeling better. Do not stop the medication abruptly without consulting your provider, as it may lead to a recurrence of symptoms or other complications.

Complete the full course of treatment as directed to minimize the risk of relapse.

If you have any concerns or questions about your medication, discuss them with your healthcare provider for personalized guidance and recommendations.

Store lamotrigine according to the instructions provided by your healthcare provider or pharmacist. Keep it at room temperature, away from light and moisture. Ensure the container is tightly closed and out of reach of children.

Do not use expired medication or medications that appear damaged or discolored. If you have any questions about storage, consult your healthcare provider or pharmacist for guidance.
