Brief Answer: Need a pulse check Detailed Answer: Hello, Good day. What is your usual dose? Common side effects are palpitations, fast heart beats, heat sensation in body etc. Do you have a heart condition or angina etc any time in the past ? If yes, meet your GP fast to do a pulse check up and may be an ECG as well. If you have a fast heart beat etc, your GP may give you a pill to slow down your heart rate. If you have vomited out tablets, dont worry. Avoid your usual dose of levothyroxine for 4-5 days. The excess dose should be out of your system in the next few days. Dont panic. It is a good idea to visit your GP and get a pulse check up. Regards XXXXXXX

Brief Answer: Not too bad Detailed Answer: Hello Good morning. So you took 6 days dose on a single day. you shouldn't take levothyroxine for the next 6 to 7 days. The half life of levothyroxine is around 7 to 10 days and it might take about 10 days or so to get out of system completely. But since you have hypothyroidism, your blood levels will fall low if you avoid medicine for a long time. Best way would be to stop tablets for 6 days and restart it then. keep watching your pulse. Occasionally we tend to give a week's full dose in a single day for people who have compliance issue. So don't worry. You will be okay. Regards Binu
