Physicians are very careful when they prescribe Xanax to patients. This is a drug which is given to patients in extreme cases of anxiety. The drug has the capacity to cool down the nerves of the patient at a time, when it is assumed that the condition of the patient might go out of control. A dose of this drug is used to induce sleep in the patient, who has been going without sleep even after going through several psychological and physical therapies. All physicians say that using the same drug over an extended period of time. This causes the body to get immuned to the drug, and does not respond to further treatment.
Xanax, like any other drug needs to be prescribed by the physician if it is desperately required by the patient. After a week of its use, its usefulness becomes questionable. These are basically prescription drugs, but there are times, when the need for this drug goes up to such a level, that it becomes an emergency to get it for the patient. In such a case, these could be obtained from the several online stores that are available on the internet. Patients or their household can purchase them from these retail outlets. For this, there is no need to take a certificate or a prescription from the physician. But it is always good to take their advice.
It must be noted that whenever a situation so arises that a particular stuff has to be purchased from online stores, care must be taken that the things to be purchased, are done from reliable outlets. This is more so in case of purchasing drugs. Drugs come with expiry date. This must be ensured by the prospective customer. In case of Xanax, these can be purchased from online shops, but only after the physician has given a nod.
