Yes, sure, heparin is side effect free as long as you do not consider a stroke or bleeding to death as side effects.
The subcutaneous injections are safe!! Patients (after deep surgery) in Switzerland are sent home with 2-3 weeks pre-filled injections they have to daily apply themselves.
If you do get COVID-19, the story below may happen to you and it can happen even to relatively young and productive people, if that matters to you. This is from a health care provider - an ICU nurse, from Facebook
It's all matter of your perspective. 95% ( see latest ant body tests - Spain Switzerland) ) of all people that get COV-19 don't see/feel any symptoms other then be a tiny headache or some cough. Even such people can later see lung, kidney damage. But such cases are very rare.
Please be aware that the press currently hypes everything as it is well known that people like/enjoy to read scary stories. Even the Kavasaki syndrome is now misused to bash the poor people even stronger.
In a perfect hospital you get the perfect treatment. But why do/did 2'000'000'000 people get HCQ without any test?? - for malaria prevention. Possibly because most were young. You can also prescribe Clarithromycin instead of Acithromycin. It is only a bit less antiviral according to the lab/chemo fit algorithm.
Do you understand that the active people (age < 65) want to work and in fact most of them are not at risk? I would narrow your advises for targeting the really endangered groups that will also become the worst spreaders. Live will and must go on and as with the classic flue, - yes - you will be very busy the next 4 months. But please do send nobody home that has clear symptoms without giving him basic medication.
Working with no clear guidelines can be trained if you once do extreme forest or mountain trips without any supportive tools. I agree that there is not enough data to fully trust in any medication. But there is more than enough evidence that at least the collected ones do help if given early enough or some (Heparin/Ivermectin) even at a very late stage. So if you give nothing then you do not trust yourself and just wait for your daddy telling you what to do in an unexpected situation.
And last: Young boys like to drive at 300kmh... so some will have a major accident. But on the other side 30% of the New York bankers take cocaine and nobody tells them about the accidents...
