OMNIVIRUS:
Thanks for specifying that if you do not know the infection don't take antibiotics. Some maybe obtained OTC, pls don't use without being sure of the infection. Try to buy Doxycycline 100mg or 200mg online without prescription but be careful with the dosage!

Antibiotics resistance is very rampant and its giving medical personnel issue across the world.

I absolutely agree with you, because antibiotics are such a specific thing that you can both help and harm!
