Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary There are no adequate and well-controlled studies with ISOPTO® Atropine 1% administration in pregnant women to inform a drug-associated risk. Adequate animal development and reproduction studies have not been conducted with atropine sulfate. In humans, 1% atropine sulfate is systemically bioavailable following topical ocular administration [see Clinical Pharmacology (12.3) ] .

ISOPTO® Atropine 1% should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.

8.2Lactation There is no information to inform risk regarding the presence of atropine in human milk following ocular administration of ISOPTO® Atropine 1% to the mother. The effects on breastfed infants and the effects on milk production are also unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ISOPTO® Atropine 1% and any potential adverse effects on the breastfed child from ISOPTO® Atropine 1%.

8.4Pediatric Use Due to the potential for systemic absorption of atropine sulfate ophthalmic solution the use of ISOPTO® Atropine 1% in children under the age of 3 months is not recommended and the use in children under 3 years of age should be limited to no more than one drop per eye per day. Safety and efficacy in children above the age of 3 months has been established in adequate and well controlled trials.

8.5Geriatric Use No overall differences in safety or effectiveness have been observed between elderly and adult patients.

8.5Geriatric Use No overall differences in safety or effectiveness have been observed between elderly and adult patients.

🆘 Overdosage 144 words ▾

10 OVERDOSAGE In the event of accidental ingestion or toxic overdosage with atropine sulfate ophthalmic solution supportive care may include a short acting barbiturate or diazepam as needed to control marked excitement and convulsions. Large doses for sedation should be avoided because central depressant action may coincide with the depression occurring late in atropine poisoning. Central stimulants are not recommended.

Physostigmine, given by slow intravenous injection of 1 to 4 mg (0.5 to 1 mg in pediatric populations), rapidly abolishes delirium and coma caused by large doses of atropine. Since physostigmine is rapidly destroyed, the patient may again lapse into coma after one to two hours, and repeated doses may be required. Artificial respiration with oxygen may be necessary.

Cooling measures may be needed to help to reduce fever, especially in pediatric populations. The fatal pediatric and adult doses of atropine are not known.

🧬 Clinical Pharmacology ~1 min read ▾

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Atropine acts as a competitive antagonist of the parasympathetic (and sympathetic) acetylcholine muscarinic receptors. Topical atropine on the eye induces mydriasis by inhibiting contraction of the circular pupillary sphincter muscle normally stimulated by acetylcholine. This inhibition allows the countering radial pupillary dilator muscle to contract which results in dilation of the pupil.

Additionally, atropine induces cycloplegia by paralysis of the ciliary muscle which controls accommodation while viewing objects.

12.2Pharmacodynamics The onset of action after administration of ISOPTO Atropine 1% generally occurs in minutes with maximal effect seen in hours and the effect can last multiple days [see Clinical Studies (14) ].

12.3Pharmacokinetics In a study of healthy subjects, after topical ocular administration of 30 µL of atropine sulfate ophthalmic solution, 1%, the mean (± SD) systemic bioavailability of l-hyoscyamine was reported to be approximately 64 ± 29% (range 19% to 95%) as compared to intravenous administration of atropine sulfate. The mean (± SD) time to maximum plasma concentration (Tmax) was approximately 28 ± 27 minutes (range 3 to 60 minutes), and the mean (±SD) peak plasma concentration (Cmax) of l-hyoscyamine was 288 ± 73 pg/mL.

The mean (±SD) plasma half-life was reported to be approximately 2.5 ± 0.8 hours. In a separate study of patients undergoing ocular surgery, after topical ocular administration of 40 µL of atropine sulfate ophthalmic solution, 1%, the mean (± SD) plasma Cmax of l‑hyoscyamine was 860 ± 402 pg/mL.

12.3Pharmacokinetics In a study of healthy subjects, after topical ocular administration of 30 µL of atropine sulfate ophthalmic solution, 1%, the mean (± SD) systemic bioavailability of l-hyoscyamine was reported to be approximately 64 ± 29% (range 19% to 95%) as compared to intravenous administration of atropine sulfate. The mean (± SD) time to maximum plasma concentration (Tmax) was approximately 28 ± 27 minutes (range 3 to 60 minutes), and the mean (±SD) peak plasma concentration (Cmax) of l-hyoscyamine was 288 ± 73 pg/mL.

The mean (±SD) plasma half-life was reported to be approximately 2.5 ± 0.8 hours. In a separate study of patients undergoing ocular surgery, after topical ocular administration of 40 µL of atropine sulfate ophthalmic solution, 1%, the mean (± SD) plasma Cmax of l‑hyoscyamine was 860 ± 402 pg/mL.

Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Atropine Sulfate (matched by generic name) — the program that covers self-administered drugs. 7 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Atropine Sulfate. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

Questions about this listing

What does the discontinued status mean for this NDC?
The labeler reported a marketing end date (or the listing was delisted), so this specific package is no longer actively marketed. Remaining stock may still be dispensed for a time, and the NDC stays valid for historical records and claims — but data feeds (pricing, labeling) typically stop updating for it. Other package sizes or other manufacturers' versions of the same medication may still be marketed — see the equivalents section where available.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Who lists this product with the FDA?
Alcon Laboratories, Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.
