These rows are manufacturer reports to the FDA for Benztropine Mesylate Injection — they do not necessarily cover every manufacturer that makes this drug. A company appears here only if it told the FDA it has a supply problem, so other makers may still have stock. That’s the basis for the Where else can I get Benztropine Mesylate Injection? options further down this page.
Why is Benztropine Mesylate Injection in shortage?
Fresenius Kabi USA, LLC has reported to the FDA that they are permanently stopping the manufacture of their benztropine mesylate injection — specifically the 1 mg/1 mL strength and package size. This isn't a temporary hold-up at the factory or a supply bump; it's a full discontinuation of that particular product from this manufacturer.
It's worth knowing that Fresenius Kabi did not share a specific public reason for why they made this decision — just that manufacturing will be discontinued. This report reflects only what this one manufacturer has filed with the FDA, so it speaks only to their version of this product.
Based on the manufacturer-reported reason(s) and notes on file with the FDA for Benztropine Mesylate Injection, summarized in plain English by HelloPharmacist. A drug can be short for more than one reason, and the FDA updates these as manufacturers report changes.
What should I do if I take Benztropine Mesylate Injection?
Benztropine mesylate injection is currently on the FDA shortage list, so I want to walk you through what that means for you.
The affected strength is the 1 mg/1 mL injection. Right now, this strength has no available source from the manufacturer that filed this report, Fresenius Kabi. They have noted that they are discontinuing this product, which means this particular supply problem may be permanent rather than temporary.
That said, this report reflects only one manufacturer. The same medicine — benztropine mesylate 1 mg/mL injection — is still listed from other makers, so it has not left the market entirely. Your pharmacy may be able to source it through one of those companies, though it may not be sitting on the local shelf.
Here is what I suggest, in order:
- Do not stop, skip, or change your dose on your own.
- Ask your pharmacy to check wholesalers and other manufacturers; the same medicine is also made by Hikma Pharmaceuticals and Zydus Pharmaceuticals.
- Because the Fresenius Kabi product is being discontinued, talk with your prescriber or pharmacist about your options going forward.
Manufacturer contact numbers are listed on this page for reference, though pharmacies usually handle these calls. This is general, national information and may not match your local pharmacy's actual stock.
- Don’t stop or change the medication on your own — talk to your prescriber first.
- If this is part of an ongoing or essential regimen (for example HIV treatment or prevention, seizure, heart, transplant, diabetes or mental-health medicines), do not skip or ration doses — contact your pharmacist or prescriber right away to arrange continued supply before you run out.
- Ask your pharmacy to check other manufacturers, strengths, package sizes, and nearby stores.
- Ask your prescriber whether a different strength, formulation, or the brand/generic version is appropriate.

Where else can I get Benztropine Mesylate Injection?
FDA shortages are manufacturer-reported — a company only shows up on the shortage list if it told the FDA it has a supply problem, so not every maker of Benztropine Mesylate Injection is necessarily short. Below we pull together the other still-marketed options that are not reported in shortage: the same medicine from manufacturers that haven’t reported a problem, and alternative dosage forms. These may still be out of stock at your pharmacy, and only your prescriber or pharmacist can decide what’s right for you.
Same medicine, other manufacturers (not reported short)
Same active ingredient, dosage form & route as the shortage (matched on the FDB HICL ingredient code), from makers that have not filed a shortage with the FDA:
| Product | Strength | Form / route | Manufacturer | NDC |
|---|---|---|---|---|
| Benztropine Mesylate | BENZTROPINE MESYLATE 1 mg/mL | Injection · Intramuscular, Intravenous | Hikma Pharmaceuticals USA Inc. | 00143-9233-05 |
| Benztropine Mesylate | BENZTROPINE MESYLATE 1 mg/mL | Injection · Intramuscular, Intravenous | Zydus Pharmaceuticals USA Inc. | 68382-0860-10 |
Alternative dosage forms of Benztropine Mesylate
A different form of the same drug (for example a solution when capsules are short). A form change is a clinical decision — ask your prescriber:
Therapeutic equivalents & pricing 5 productsclick to expand
Orange Book–rated equivalents of the affected strengths, with the latest NADAC price (a federal retail-acquisition benchmark, not your copay) and an evidence-based availability label. Cheapest first.
| Product | Manufacturer | Package | NADAC $/unit | AB rating | Availability |
|---|---|---|---|---|---|
| Benztropine Mesylate 1 mg/mL | Hikma | 5 vials | — | AP | FDA listed |
| Benztropine Mesylate 1 mg/mL | Hikma | 5 ampules | — | AP | FDA listed |
| Benztropine Mesylate 1 mg/mL | Fresenius | 5 vials | — | AP | FDA listed |
| Benztropine Mesylate 1 mg/mL | Zydus | 5 vials | — | AP | FDA listed |
| Benztropine Mesylate 1 mg/mL | Navinta | 5 vials | — | AP | FDA listed |
Equivalents share the same ingredient, strength, dosage form and route; an AB rating means the FDA considers them substitutable. NADAC is a national retail-pharmacy acquisition benchmark from CMS — not what you pay. Availability is inferred from recent pricing, not a stock check.
Other drugs in the same treatment class
These are different medicines — not other versions of Benztropine Mesylate Injection — that fall in the same broad treatment class (antiparkinsonism drugs,anticholinergic) . They are not automatic substitutes: they can differ in how they work, dosing, effectiveness, side effects and what they’re approved to treat. Do not switch on your own. This list is for information only — ask your prescriber or pharmacist whether any of them is appropriate for you.
