Age
Conditions you have
Other medications or supplements you take
Lifestyle habits, such as drinking alcohol or smoking

Reputed sites that sell medications are those that:
Require a prescription from a licensed US healthcare provider
Are a licensed pharmacy in good standing in the US
Have a licensed pharmacist available to answer your questions
Sell drugs that are FDA-approved
Have clear policies to protect privacy

This includes sites that ask you to fill out a questionnaire with respect to prescription. Such a questionnaire is not a substitute for careful evaluation by doctor.
You can check with the National Association of Boards of Pharmacy (NABP) to find out if a site meets state and federal requirements. Some sites even display the NABP seal of approval for Verified Internet Pharmacy Practice Sites (VIPPS).

Beware of Unreasonable Claims
Do not buy a drug from a site that makes outrageous claims about "amazing results," "a new cure," or a "cure all." It sounds cliche, but if something seems too good to be true, it probably is. If you think that you need a certain medication, talk to doctor first.
Buy Only From US-Based Sites
Companies outside the US are not regulated in the same way that US companies are. Although it may be a reputable company, you have no way of confirming that. Within the US, companies that sell drugs online can obtain a seal of approval from NABP. You can also contact the NABP to check on a particular site. In addition, generally it is illegal to import the drugs you buy from a foreign site, and the US government may not be able to help you if you have a reaction or get ripped off.
Only Buy Drugs That Are FDA-Approved
The FDA ensures the safety and efficacy of medications in the US. You take a risk with your health when you buy a drug that is not approved by the FDA.
Check Prices
Online medication prices are not always better than prices in a regular drugstore. Call your local pharmacy and ask how much the drug costs and compare that to the online price after taking online consultation. Also, make sure that the pharmacy is covered by a health insurance plan. In many states, drug stores are required to dispense generic drugs, which can save money after taking consult doctor online.
