Losartan, sold under the trade name Cozaar among others, is a medication mainly used to treat high blood pressure. It is also used for diabetic kidney disease, heart failure, and left ventricular enlargement. It is taken by mouth. It may be used alone or in addition to other blood pressure medication.
The most common error people make with their medicines is taking – or giving – a double dose. Or, someone gets distracted and takes a prescription medicine once – and then again. For some medicines, an extra dose can cause problems. For example, too much blood pressure medicine could make you light-headed. Too much diabetes medicine can cause low blood sugar. And, you could run out of a medicine too soon.
What to do if you accidentally took double dose of Losartan
The tablets should be swallowed with a glass of water. You should try to take your daily dose at about the same time each day. It is important that you continue to take Losartan tablets until your doctor tells you otherwise.

Symptoms of overdose are low blood pressure, increased heartbeat, possibly decreased heartbeat. If you forget to take Losartan tablets or you accidentally miss a daily dose, just take the next dose as normal. Do not take a double dose to make up for a forgotten tablet. If you have any
How long does it take for losartan to get out of your system?
After a losartan dose, the body converts it to an active metabolite. The metabolite provides much of losartan’s blood pressure lowering effects. The losartan half-life is about 2 hours and the metabolite half-life is 6 to 9 hours. This means it can take a couple of days to clear losartan and its metabolite from your system.
