8 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?

Data sourced from official FDA Structured Product Labeling (SPL) via DailyMed — ingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?

No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.

Why might an inactive ingredient be missing?

Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.

Can inactive ingredients matter?

Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price system	Per each	Per package
Retail pharmacies payNADAC · weekly	Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo	No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · Q2 2026	$60.43	$6,042.64 / 100 tablets

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.

Questions about this listing

Why is there no price listed?

The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.

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 FDA registers it as 69413-558-40, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 69413-0558-40, written without dashes as 69413055840. The Identity section at the top of this page lists every form of this code.

What do the three segments of this NDC mean?

In 69413-0558-40, the first segment (69413) is the labeler code FDA assigned to Vyera Pharmaceuticals, LLC; the middle segment (0558) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (40) identifies this exact package size and type. Together they name one specific package of one specific product.

Is this package still being marketed?

Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Vyera Pharmaceuticals, LLC. Listing status can change — the directory data on this page refreshes weekly.

Who lists this product with the FDA?

Vyera Pharmaceuticals, LLC 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?

🎯 Indications and Usage 20 words ▾

INDICATIONS AND USAGE For the management of moderately severe to severe essential hypertension and in uncomplicated cases of malignant hypertension.

⏱️ Dosage and Administration ~2 min read ▾

DOSAGE AND ADMINISTRATION Therapy is usually started with one 2.5 mg tablet of Mecamylamine HCl twice a day. This initial dosage should be modified by increments of one 2.5 mg tablet at intervals of not less than 2 days until the desired blood pressure response occurs (the criterion being a dosage just under that which causes signs of mild postural hypotension). The average total daily dosage of Mecamylamine HCl is 25 mg, usually in three divided doses.

However, as little as 2.5 mg daily may be sufficient to control hypertension in some patients. A range of two to four or even more doses may be required in severe cases when smooth control is difficult to obtain. In severe or urgent cases, larger increments at smaller intervals may be needed.

Partial tolerance may develop in certain patients, requiring an increase in the daily dosage of Mecamylamine HCl. Administration of Mecamylamine HCl after meals may cause a more gradual absorption and smoother control of excessively high blood pressure. The timing of doses in relation to meals should be consistent.

Since the blood pressure response to antihypertensive drugs is increased in the early morning, the larger dose should be given at noontime and perhaps in the evening. The morning dose, as a rule, should be relatively small and in some instances may even be omitted. The initial regulation of dosage should be determined by blood pressure readings in the erect position at the time of maximal effect of the drug, as well as by other signs and symptoms of orthostatic hypotension.

The effective maintenance dosage should be regulated by blood pressure readings in the erect position and by limitation of dosage to that which causes slight faintness or dizziness in this position. If the patient or a relative can use a sphygmomanometer, instructions may be given to reduce or omit a dose if readings fall below a designated level or if faintness or lightheadedness occurs. However, no change should be instituted without the knowledge of the physician.

Close supervision and education of the patient, as well as critical adjustment of dosage, are essential to successful therapy. Other Antihypertensive Agents When Mecamylamine HCl is given with other antihypertensive drugs, the dosage of these other agents, as well as that of Mecamylamine HCl, should be reduced to avoid excessive hypotension. However, thiazides should be continued in their usual dosage, while that of Mecamylamine HCl is decreased by at least 50 percent.

⛔ Contraindications 82 words ▾

CONTRAINDICATIONS Mecamylamine HCl should not be used in mild, moderate, labile hypertension and may prove unsuitable in uncooperative patients. It is contraindicated in coronary insufficiency or recent myocardial infarction. Mecamylamine HCl should be given with great discretion, if at all, when renal insufficiency is manifested by a rising or elevated BUN.

The drug is contraindicated in uremia. Patients receiving antibiotics and sulfonamides should generally not be treated with ganglion blockers. Other contraindications are glaucoma, organic pyloric stenosis or hypersensitivity to the product.

⚠️ Warnings 124 words ▾

WARNINGS Mecamylamine, a secondary amine, readily penetrates into the brain and thus may produce central nervous system effects. Tremor, choreiform movements, mental aberrations, and convulsions may occur rarely. These have occurred most often when large doses of Mecamylamine HCl were used, especially in patients with cerebral or renal insufficiency.

When ganglion blockers or other potent antihypertensive drugs are discontinued suddenly, hypertensive levels return. In patients with malignant hypertension and others, this may occur abruptly and may cause fatal cerebral vascular accidents or acute congestive heart failure. When Mecamylamine HCl is withdrawn, this should be done gradually and other antihypertensive therapy usually must be substituted.

On the other hand, the effects of Mecamylamine HCl sometimes may last from hours to days after therapy is discontinued.

🤒 Adverse Reactions 80 words ▾

ADVERSE REACTIONS The following adverse reactions have been reported and within each category are listed in order of decreasing severity. Gastrointestinal: Ileus, constipation (sometimes preceded by small, frequent liquid stools), vomiting, nausea, anorexia, glossitis and dryness of mouth. Cardiovascular: Orthostatic dizziness and syncope, postural hypotension.

Nervous System/Psychiatric: Convulsions, choreiform movements, mental aberrations, tremor, and paresthesias (see WARNINGS ). Respiratory: Interstitial pulmonary edema and fibrosis. Urogenital: Urinary retention, impotence, decreased libido.

Special Senses: Blurred vision, dilated pupils. Miscellaneous: Weakness, fatigue, sedation.

🔄 Drug Interactions 30 words ▾

Drug Interactions Patients receiving antibiotics and sulfonamides generally should not be treated with ganglion blockers. The action of Mecamylamine HCl may be potentiated by anesthesia, other antihypertensive drugs and alcohol.

🤰 Pregnancy 49 words ▾

Pregnancy Pregnancy Category C. Animal reproduction studies have not been conducted with Mecamylamine HCl. It is not known whether Mecamylamine HCl can cause fetal harm when given to a pregnant woman or can affect reproductive capacity. Mecamylamine HCl should be given to a pregnant woman only if clearly needed.

🧒 Pediatric Use 12 words ▾

Pediatric Use Safety and effectiveness in pediatric patients have not been established.

🆘 Overdosage 87 words ▾

OVERDOSAGE Signs of overdosage include: hypotension (which may progress to peripheral vascular collapse), postural hypotension, nausea, vomiting, diarrhea, constipation, paralytic ileus, urinary retention, dizziness, anxiety, dry mouth, mydriasis, blurred vision, or palpitations. A rise in intraocular pressure may occur. Pressor amines may be used to counteract excessive hypotension.

Since patients being treated with ganglion blockers are more than normally reactive to pressor amines, small doses of the latter are recommended to avoid excessive response. The oral LD 50 of Mecamylamine HCl in the mouse is 92 mg/kg.

🧬 Clinical Pharmacology 135 words ▾

CLINICAL PHARMACOLOGY Mecamylamine HCl reduces blood pressure in both normotensive and hypertensive individuals. It has a gradual onset of action (1/2 to 2 hours) and a long-lasting effect (usually 6 to 12 hours or more). A small oral dosage often produces a smooth and predictable reduction of blood pressure.

Although this antihypertensive effect is predominantly orthostatic, the supine blood pressure is also significantly reduced. Pharmacokinetics and Metabolism Mecamylamine HCl is almost completely absorbed from the gastrointestinal tract, resulting in consistent lowering of blood pressure in most patients with hypertensive cardiovascular disease. Mecamylamine HCl is excreted slowly in the urine in the unchanged form.

The rate of its renal elimination is influenced markedly by urinary pH. Alkalinization of the urine reduces, and acidification promotes, renal excretion of mecamylamine. Mecamylamine HCl crosses the blood-brain and placental barriers.
