Today on Healthy Talk, you wanted to know:How often can I safely use hand sanitizers?There's no definite answer to exactly how many times a day you should be using hand sanitizers. However, Dr. Mike suggests that if you're around soap and water, you should always go with that. It's only when you don't have access to soap and water that hand sanitizers come in handy.What is the maximum dose of acetaminophen?If you're concerned about how much acetaminophen you can take, make sure you're reading the labels of all over-the-counter medicines you're taking. You can also check the website, Drugs.com. Dr. Mike suggests 3,000 milligrams a day or less.I'm a 60-year-old female, basically healthy and have been taking Aspirin (81 milligrams) ever since 2006. A few months ago I started taking ginseng. Should I stop taking the Aspirin? I don't have a heart problem at this point, and I read a Mayo clinic report that taking Aspirin is not good.A little bit ago, there was a study conducted on whether or not it was worth taking Aspirin every day. The results concluded that if you have no cardiovascular risk, then there's no reason you should take it.In Dr. Mike's opinion, stick with the ginseng and forget the Aspirin.I take DHEA, should I take that on an empty stomach?Yes. Some supplements work better on an empty stomach, and DHEA is one of them.I know vitamin K2 is good from listening to your show. Each time I've tried to take it, my lips became numb, so I stopped. I learned I can eat more cheese to get my vitamin K2. Is that true?Yes. You can get vitamin K2 from cheese, just make sure you're not overdoing it.If you have a health question or concern, Dr. Mike encourages you to write him at askdrmikesmith@radiomd.com or call in, toll-free, to the LIVE radio show (1.877.711.5211) so he can provide you with support and helpful advice.
