I went to the doctor on Saturday after being sick for most of last week. Didn’t feel like it was getting better. My symptoms weren’t too bad though: bad congestion; headaches; fatigue. No fever, sore throat, or other symptoms. I was scheduled to see my parents yesterday and wanted to make sure I didn’t have the flu.

Flu/covid was negative.

He said my sinus turbinates were red and then prescribed me 500mg of Amoxicillin three times a day for ten days.

Just seems excessive for what is essentially a head cold, right? No fever means no bacterial infection, but he figured 1500mg of Amoxicillin was necessary.

What’s the protocol for figuring out how much is needed?

(over/under comments about the jab is set at 10)

Doctors dont. The pharmacist formulate most dosages.

Lots of research by the drug company determines the correct dosing.

Just get it filled and don't take it or wait another couple days to see if it clears up on its own. Save it for the next time you are really sick.

Or save for the apocalypse.

European medicine has proven it is best to hit it hard and American medicine is slowly coming around. Don’t waste time with a weak prescription. That old school fear is causing the anti-biotics resistance.

Weight based dosing that’s determined by the pharmaceutical company through research and formulation of the medication

True, ask any Pharmacist...

They will tell you they are more intelligent, and most Doctors are idiots.

Don't be wowed by the number of milligrams. Each drug has a different potency.

Just got over the cold/flu and the same for me. My doctor said it was a sinus infection. My Amoxicillin prescription was 800 mg twice a day. It appears that prescribing Amoxicillin is not an exact science. You just need enough in your system to kill the bacteria.

That’s good advice. I always save a few when I get them. They shouldn’t make you go to the doctor when you know you only need antibiotics. Money grab.

There are guidelines. You are giving doctors too much credit.

By understanding the pharmacology behind the drug, evaluating the nature and extent of the patient's issue, and making an assessment based on reasoned, medical principles they've studied and honed over years of practice.

You probably had adenovirus and prescribing antibiotics was just to do something as opposed to fixing your problem. It’s a virus, it will go away in 7-10 days.

Some are weight based, some are based on what they are trying to treat. Could have different doses depending if they are treating a UTI as opposed to Pneumonia

This.

I have a little booklet made yearly that I keep on hand. I got a 56 on my pharmacology final so you don’t want me figuring it out on my own

Amazing some people have no idea how the world works.

Doctor sends in a prescription, pharmacist checks it to make sure dosing is appropriate and directions are clear. Half of your family med clinics have an LPN send in an electronic script that was mistyped or put in for the wrong dose or quantity
