No, you cannot just go to a pharmacy and ask for antibiotics. If you suspect that you have an infection due to bacteria, the best thing to do is visit your doctor and get tested. Your doctor can perform tests such as blood or urine cultures to determine if an infection is present. They will also be able to tell what specific type of antibiotic would work best against the bacterial strain causing your illness. Pharmacists are not allowed by law to prescribe medication without a valid prescription from a licensed medical practitioner which makes it impossible for them to dispense antibiotics without one. Additionally, taking antibiotics without consulting with a physician may lead to further complications down the road since there are many bacteria that are resistant now-a-days so it’s important that you take the correct course of treatment prescribed by your doctor in order for it work properly.
