Compounded Medications: What They Are and What to Ask
September 20, 2026 · 6 min read
Compounded medications have become common in telehealth, including combination ED formulations and dissolvable tablets. They're legal and often clinically appropriate — but they sit in a genuinely different regulatory position than the approved products most people assume they're getting.
What compounding is
A licensed compounding pharmacy prepares a medication tailored to a specific patient's needs — a different dose, a different form (dissolvable rather than swallowed), removal of an allergen, or a combination not available commercially. This has existed as long as pharmacy has.
The regulatory difference
FDA does not review compounded drugs for safety, effectiveness or quality before they reach patients. Approved medications go through clinical trials and manufacturing inspection; compounded preparations rely on the compounding pharmacy's own standards and state oversight, with 503B outsourcing facilities held to stricter federal manufacturing standards than traditional 503A pharmacies. That's not a claim that compounded drugs are unsafe — it's a claim that the assurance is different, and you should know which one you're getting.
Why combination ED products are compounded
There is no FDA-approved tadalafil/sildenafil combination product. Any product combining them is compounded by definition, and the combination itself has not been through the approval process even though both individual molecules have. Any service selling one should say so plainly and prominently.
Questions to ask
A legitimate provider will answer all of these without hedging.
- Which pharmacy compounds it, and is it a 503A or 503B facility?
- Is this product FDA-approved, and if not, is that disclosed clearly?
- What testing is done on potency and sterility?
- Why is a compounded version clinically appropriate for me specifically?
- What are the total doses of each active ingredient, and how do they compare to standard approved doses?
The short version
Compounding is legitimate; the regulatory gap is real. Ask which pharmacy, ask about testing, and expect the non-approved status stated up front.
