The FDA recommends caution before purchasing or using any pills, beverages, chewing gum, or dissolving oral strips that:

  • Promise results as soon as within half an hour
  • Claim to be alternatives to prescription ED drugs
  • Are sold through unsolicited e-mails
  • Are sold in single-serving packages

Also be suspicious of “all-natural” ED remedies that have labels written entirely or mostly in a language other than English, or that seem to be copying the appearance of FDA-approved drugs.
