What should I do if I miss a dose or overdose on Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate Tablets?

Handling of missed doses: If you miss a dose≤12 hours, take it immediately; if it exceeds 12 hours, skip it and take the medicine as originally planned the next day. Overdose treatment: There is currently no specific antidote, vital signs need to be monitored, and gastric lavage or supportive treatment is required if necessary. Prolonged overdose may increase the risk of hepatotoxicity. Tenofovir may cause renal tubular damage, manifested as decreased serum phosphorus and increased creatinine, and renal function needs to be monitored regularly. Efavirenz may cause elevated liver enzymes, especially in patients with a history of liver disease. If symptoms such as jaundice or darker urine occur, you need to stop taking the medicine immediately and seek medical advice.
