Patient discussion about overdose

Q. so, like I know you can die of a drug overdose, but can you die of an alcohol overdose as well?

A. of course you can!!! you better not try to prove me wrong on this one... each one of us has a different threshold of how much is just a bit too much for him so you shouldn't get to exaggerated amounts cause you can't tell hoe sensitive you are to it.

Q. My husband takes Zocor (20mg) for his hyperlipidemia. by mistake he took 3 pills (60mg). What to do? My husband suffers from high blood lipids and he is treated with Zocor (Simvastatin). he should take one pill of 20 mg per day. By accident he took 3 pills (60mg) in one day. what to do?

A. You need to call your GP. Zocor doses are between 20-80 mg but maybe your husband has other problems (mainly in his kidneys) that will interfere with the normal way of cleaning the body from the drug.
Zocor overdose symptoms will be myalgia and red urine (in a severe overdose) if your husband have one of those symptoms go to the ER as soon as possible.

Q. Is drinking too much water harmful? Is there a condition like “water overdose”?

A. Drinking more water then you are used to is very good for you. But of course if you over do it it’s damaging. Drinking way too much will make you urinate more, this means you will also loose vital minerals in the urine like potassium and sodium. This can even lead to death.
