Lamitor DT contains lamotrigine, and more affordable generic versions with the same active ingredient may be available, but the exact substitute should be chosen by a doctor or pharmacist to ensure the same strength and formulation. Since you have been stable for 3 years, dose reduction may sometimes be considered, but it is not advisable to reduce from 1-0-1 to 1-0-0 without psychiatric supervision. Stopping or tapering lamotrigine too quickly may increase the risk of relapse or mood instability. Because you have not had follow-up for over a year, it is important to consult your psychiatrist before making any medication changes.

This dispensing error, where Lamitor DT 50 (a twice-daily dispersible tablet) was mistakenly replaced with Lamitor OD 50 (a sustained-release formulation), requires immediate consultation with the prescribing doctor. The two forms differ in how the medication is released and absorbed in the body. The OD form releases the drug slowly, which may result in low drug levels and poor seizure control if taken twice daily. On the other hand, continuing the OD form twice daily may cause excessive drug accumulation. The doctor will guide you on how to safely switch back to the correct formulation to maintain stable drug levels and ensure effective seizure control.
