None can dispute online pharmacies utility. Health authority’s main worry is that this convenience is not abused to harm the consumers.

Some “rogue sites" sell unapproved products. Many ignore a prescription before providing a drug and bypass interaction with a health professional. Some offer ridiculously low prices, even selling fake or outdated drugs. These ethical violations and impure products can result in dangerous drug interactions.

Pharmacies offering a prescription drug for the first time without a physical test, sell without a prescription, or sell drugs not approved by FDA, must be avoided. Sites that do not provide access to a registered pharmacist must be shunned.

Beware of sites that advertise a new or quick medicine for a serious disease. Such quacks impress customers by using high sounding terminology to cover their dubious operations or by telling some stories of persecution by government, medicos, or researchers. Buyers should also stay away from sites claiming miracle results.
