One of the biggest problems with medicines being used right now is their limited workability. These medicines may carry potent enzymes and properties which work to target the virus, but depending on your age, severity and sensitivity, COVID medicines may not work for everyone. It is also a cumbersome task to design different medicines for different symptoms.
For example, some of the most talked and beneficial drugs used right now, such as dexamethasone and redeliver, do NOT work for everyone diagnosed with COVID-19. While dexamethasone has been found to be the most effective for people with moderate or severe COVID.
Tocilizumab, which is being used as an investigational therapy right now works as an immunosuppressant. If the dosage is not disproportionately, it can lead to blood infections, swelling and shock the body.
Remdesivir, which is an anti-viral medication has also been linked to limited use, only reserved for emergent use initially.
Some people can also be allergic to certain medications. Age factor and using other medications can also deem certain treatment drugs ineffective. A broader conclusive study will be needed before we can safely trust treatment strategies.
Other treatment options, such as plasma therapy have still not been found to be completely effective for everyone. Despite the benefits, several global trials have talked about the problems associated with this. While the same risks apply to vaccines as well, use of adjuvants and other related immunity boosters can negate the risk factors.
