Ganciclovir Generic: When Will Generic Ganciclovir Be Available?
This page is aggregated from FDA records, court filings and company announcements. Coded and designed by Dr. Brian Staiger, PharmD, BCPS
Updated October 9, 2026 How we build our data
Ganciclovir Generic at a Glance
Four quick answers from FDA records and our estimate.
- When is the first generic expected? September 2034 About 8 years away Why then?
- Has the FDA approved a generic? Unknown No FDA Orange Book record under this name
- When does the brand’s protection end? Unknown Not in the FDA record we could read
- Can you buy a generic today? Yes 3 companies list one
It already is. A generic ganciclovir is listed for sale by 3 companies, so ask your pharmacy whether it can fill your prescription with one.
Why September 2034?
A patent that protects the brand runs out. After that, approved generics can be sold. We rate it probable: more likely than not, but it can still move.
What should I do now?
Ask your pharmacy whether it can fill your prescription with a generic. It may look different from Ganciclovir, but the active ingredient, strength and form are the same. What a generic means for you
Our month is only an estimate based on available information, so we never name a day.

Ganciclovir’s Road to a Generic
The first generic of Ganciclovir is expected in September 2034.
Why that month: a patent that protects the brand runs out. After that, approved generics can be sold.
The bar shows Ganciclovir on the market on its own until the month we expect the first generic (the green band), a month and never a day. Its approval date and patents are not in the FDA Orange Book under this name, so the bar fades in from the left. The expected month comes from court records and company announcements.
Who Is Lined Up to Make Generic Ganciclovir
Three steps stand between a brand and a generic you can buy: a company applies to the FDA, the FDA approves it, and the company starts selling it.
Applied to the FDA
No company is recorded as having applied to the FDA to make a generic Ganciclovir yet.
Approved by the FDA
We could not find Ganciclovir’s own record in the FDA Orange Book under this name, so the approved generic makers are not shown.
For Sale in Pharmacies
Yes. A generic ganciclovir is listed for sale by 3 companies. Ask your pharmacy whether it can fill your prescription with it.
Endo USA, Inc., Par Health USA, LLC and Par Pharmaceutical, Inc.

Ganciclovir Price: What Pharmacies Pay and What Generics Usually Do
What a Generic Could Cost
How we estimate it. The national survey of what pharmacies pay (NADAC) has no recent price for Ganciclovir, so we cannot show dollars. Here is the FDA’s finding of how far the price pharmacies pay usually falls as generic companies join: about 31% with one company, 44% with two, 73% with four and over 95% with six or more (the typical drop for every drug whose first generic came out from 2015 to 2017).
Median prices pharmacies paid for the generic (invoice prices), compared with the brand’s price before generic entry, from FDA’s 2019 analysis “Generic Competition and Drug Prices”. At the manufacturer’s price FDA found steeper drops (about 39%, 54%, 79% and over 95%), the figures quoted elsewhere on this tracker. A typical pattern, not a price quote for this medicine.
Ganciclovir NDC Codes and Packages
Each Ganciclovir package sold today has its own NDC, the product number printed on the box and on the pharmacy label. Open one to see that package’s details, what pharmacies pay for it and its patent timeline.
| NDC | Product | Package | Company |
|---|---|---|---|
| 51754-2500-01 | 2 mg/mL injection, solution | bag of 250 mL | Exela Pharma Sciences, LLC |
| 51754-2500-03 | 2 mg/mL injection, solution | pouch of 10 bags of 250 mL | Exela Pharma Sciences, LLC |

What a Generic Ganciclovir Means for You
Nothing Changes Until It Is in Pharmacies
A generic is listed for sale now, so your pharmacy may already be able to fill your prescription with it.
Your Pharmacy May Switch You Automatically
Every state lets pharmacists fill a brand-name prescription with an FDA-approved generic rated as equivalent to it, and about 19 states require them to, unless your prescriber writes “dispense as written” or “brand medically necessary” on the prescription. Some states ask the pharmacist to tell you, or to get your OK first. A study of every state’s law has the details.
It Will Probably Look Different
US trademark law does not let a generic look exactly like the brand, so the color, shape or markings usually change. The active ingredient, strength and form are the same. An “authorized generic,” made by or for the brand’s own company, can look identical. The FDA explains.
Your Insurance May Change Too
Once a lower-cost version is available, many insurance plans charge more for the brand, or stop covering it. Your plan’s drug list (formulary) says how.
Questions people ask about Ganciclovir
Is there a generic for Ganciclovir right now?
Yes. The FDA NDC Directory lists a generic ganciclovir from 3 companies. Ask your pharmacy whether it can fill your prescription with it.
When will Ganciclovir go generic?
It already has. The FDA NDC Directory lists a generic ganciclovir from 3 companies, so ask your pharmacy whether it can fill your prescription with one.
Will generic ganciclovir be the same as Ganciclovir?
Yes in the ways that matter: the same active ingredient, strength and form, with proof that it reaches your blood the same way. Inactive ingredients can differ, which is why some people notice a different look or taste.
How much will the generic cost?
Nobody can say for sure before launch. No company is recorded as having applied to the FDA to make one yet, and a single company usually brings only a modest drop.
