We suggest that patients be prudent and reasonable in their preparedness. Together with pharmacists, government agencies and others, the pharmaceutical supply system recommends that patients do not over-buy drugs. If you have concerns about a specific medication, consult your pharmacist. We recommend that you should get your prescription refilled when you have a five to seven day supply remaining. For important nonprescription medications and medical supplies, it's also a good idea to replenish your regular supply a few days before running out.
Drugs can lose their efficacy over time.
In addition, over-buying will deplete the nation's supply system. Because wholesalers have several weeks' excess supply of most drugs, pharmacies will be within easy access of this natural cushion. If some consumers buy an excess of medications, it will create an imbalance in the system so that others may not have access to the drugs that they need. Pharmacies fully expect to have substantial supplies of drugs on hand. For this reason, pharmacies will have a 90-day supply of most drugs available to draw upon.
