Vanacof AC is an over-the-counter oral liquid manufactured by GM Pharmaceuticals, Inc. It combines two active ingredients: chlophedianol hydrochloride 12.5 mg (a non-narcotic cough suppressant) and pyrilamine maleate 25 mg (a first-generation antihistamine) per 30 mL dose. It is decongestant-free, alcohol-free, and not a controlled substance.
Vanacof AC temporarily relieves cough due to minor throat and bronchial irritation, along with allergy symptoms including runny nose, sneezing, itchy or watery eyes, and itching of the nose or throat. It is indicated for symptoms caused by the common cold, hay fever (allergic rhinitis), or other upper respiratory allergies.
Because it contains no decongestant, Vanacof AC is particularly useful for patients who cannot take pseudoephedrine or phenylephrine — including those with hypertension, heart disease, benign prostatic hyperplasia, or hyperthyroidism.

Vanacof AC works through two distinct pharmacological mechanisms corresponding to each of its active ingredients. Chlophedianol hydrochloride is a centrally-acting antitussive — it works in the brainstem's cough center to raise the threshold for the cough reflex, reducing both the frequency and intensity of coughing episodes without opioid activity or addiction risk.
Pyrilamine maleate is a first-generation H1 antihistamine that competitively blocks histamine receptors throughout the body. By preventing histamine from binding to H1 receptors in the nasal mucosa, eyes, and throat, pyrilamine reduces rhinorrhea, sneezing, pruritus, and lacrimation associated with allergic reactions and upper respiratory infections.
As a first-generation antihistamine, pyrilamine crosses the blood-brain barrier, which accounts for its sedating side effect. Onset of action for both components is typically 30–60 minutes after an oral dose, with effects lasting approximately 6 hours — consistent with the recommended every-6-hours dosing schedule.
12.5 mg / 25 mg per 30 mL — Oral liquid
Chlophedianol HCl 12.5 mg + Pyrilamine Maleate 25 mg per 30 mL dose; 4 doses per 24 hours maximum

Same active ingredients as Vanacof AC but in 15 mL dose volume (Vanacof CP formulation)
Vanacof AC has a findability score of 52/100, indicating intermittent availability challenges. While there is no active FDA-declared drug shortage, the product's limited distribution network — it is made by regional manufacturer GM Pharmaceuticals — means it is not stocked at every pharmacy. Large chain pharmacies (CVS, Walgreens, Walmart Pharmacy) often do not carry it, while independent and specialty pharmacies are more likely to have it in stock.
Availability is particularly tight during fall and winter cough-and-cold season (October through March). If you are having difficulty finding Vanacof AC, medfinder can call pharmacies near you to check which ones have it in stock and text you the results — saving you hours of phone calls.
Equivalent alternatives — including Ninjacof and Vanacof CP, both containing the same active ingredients — may be more readily available and are worth asking about if Vanacof AC specifically cannot be located.
Vanacof AC is not a controlled substance, so there are no DEA scheduling restrictions on who can prescribe it. Any licensed healthcare provider with prescribing authority can recommend or write a prescription for Vanacof AC. Because it is an OTC product, no prescription is legally required for purchase — but a prescription is needed to use insurance coverage or prescription discount programs.
Primary Care Physicians (Family Medicine, Internal Medicine)
Allergists and Immunologists
Pediatricians (for age-appropriate patients)
Nurse Practitioners (NPs) — in all 50 states
Physician Assistants (PAs)
Urgent Care Providers
Telehealth providers can also prescribe Vanacof AC without restriction in all states, making it convenient to obtain a prescription via same-day or on-demand telehealth platforms such as Teladoc, MDLive, or Amazon Clinic for cold and allergy symptoms.
No. Vanacof AC is not a controlled substance. It contains chlophedianol hydrochloride and pyrilamine maleate — neither of which is scheduled under the DEA Controlled Substances Act. Chlophedianol is a non-narcotic, non-opioid cough suppressant, and pyrilamine is a first-generation antihistamine with no abuse potential or scheduling.
Because Vanacof AC is not a controlled substance, there are no DEA prescription restrictions, no quantity limits related to controlled status, and no requirement for a DEA-licensed prescriber. Any licensed healthcare provider (MD, DO, NP, PA) can recommend or prescribe it. It is available over the counter without any prescription.
This contrasts with other cough syrups that contain codeine (Schedule V controlled substance) or other opioids (Schedule II–III). Vanacof AC is specifically formulated as a non-narcotic alternative, making it appropriate for patients who need cough suppression without the risks associated with opioid-containing products.
The following side effects are commonly reported with Vanacof AC:
Drowsiness or sleepiness (most common — from pyrilamine)
Dizziness
Dry mouth, nose, or throat
Blurred vision
Nausea or upset stomach
Headache
Excitability or hyperactivity (paradoxical reaction in children)
Seizures (call 911)
Hallucinations (may indicate overdose)
Difficulty breathing or chest tightness
Severe or unusual drowsiness (especially if combined with other CNS depressants)
Difficulty urinating
Allergic reaction (rash, hives, facial/throat swelling)

Vanacof AC is a valuable OTC option for patients who need cough and antihistamine relief without a decongestant. Its non-narcotic, non-scheduled status makes it accessible and lower-risk compared to codeine-based cough syrups, while its decongestant-free formulation expands its use to patients with hypertension, cardiovascular disease, and other conditions that preclude standard combination cold medications.
The primary challenge with Vanacof AC is access — it is manufactured by a smaller regional company and is not widely distributed through national pharmacy chains. Patients and providers should plan ahead and use pharmacy search tools to locate available stock. Equivalent products like Ninjacof and Vanacof CP with the same active ingredients offer backup options when Vanacof AC is unavailable.
If you're struggling to find Vanacof AC at your pharmacy, medfinder is the fastest way to locate it near you. medfinder calls pharmacies on your behalf and texts you the results — so you spend your time picking up your medication, not searching for it.
