The Doxylamine Succinate 10 mg/Pyridoxine HCl 10 mg Slow Release (MEM4) Oral Capsules are a specialized pharmaceutical formulation designed to alleviate symptoms associated with specific disease states. Each capsule contains a combination of doxylamine succinate and pyridoxine hydrochloride (vitamin B6), both dosed at 10 mg, and is compounded using Methocel E4M. This controlled-release polymer ensures that the active ingredients are released gradually over an extended period, providing sustained therapeutic effects.
This formulation is primarily used to treat nausea and vomiting of pregnancy (NVP), commonly known as morning sickness, which can significantly impact a pregnant woman's quality of life. The slow release mechanism of the capsules allows for reduced dosing frequency, which may enhance patient compliance and provide consistent symptom relief throughout the day. Additionally, the use of Methocel E4M in the capsule matrix helps to maintain steady blood levels of the active ingredients, potentially minimizing the risk of peaks and troughs that could lead to side effects or decreased efficacy.
By combining doxylamine succinate, an antihistamine that possesses antiemetic properties, with pyridoxine hydrochloride, which has been shown to have a beneficial effect on NVP, this formulation offers a dual approach to managing symptoms.

The Doxylamine Succinate 10 mg/Pyridoxine HCl 10 mg Slow Release (MEM4) Oral Capsules are a specialized pharmaceutical formulation designed to provide a controlled release of the active ingredients doxylamine succinate and pyridoxine hydrochloride. Doxylamine succinate is an antihistamine with sedative properties, commonly used to treat symptoms of allergies, the common cold, and as a short-term sleep aid. Pyridoxine hydrochloride, also known as vitamin B6, is essential for many bodily functions, including neurotransmitter synthesis, and is often used to prevent or treat low levels of vitamin B6, as well as to alleviate nausea and vomiting during pregnancy.
This unique formulation incorporates Methocel E4M, a hydrophilic methylcellulose derivative, which acts as a controlled-release polymer. When encapsulated with the active ingredients, Methocel E4M swells and forms a gel barrier upon contact with gastrointestinal fluids. This gel barrier controls the rate at which the active ingredients are released into the body, ensuring a gradual and sustained release over an extended period. This slow-release mechanism allows for a reduction in dosing frequency, which can lead to improved patient compliance, especially beneficial for those who require consistent therapeutic levels of medication throughout the day or night.
The dual action of doxylamine's antiemetic effects and pyridoxine's role in nausea reduction provides a synergistic approach to managing NVP symptoms. The controlled-release aspect of the formulation ensures that the therapeutic effects are maintained, potentially providing relief for a more extended period than immediate-release formulations.
For patients and prescribers considering this formulation, it is important to note that the slow-release capsules should be swallowed whole and not crushed or chewed, to maintain the integrity of the controlled-release system. As with any medication, potential side effects, contraindications, and interactions with other drugs should be reviewed with a healthcare provider. The compounding pharmacists at Bayview Pharmacy are available to answer any questions regarding this formulation and can provide additional information tailored to individual patient needs or prescriber requirements. If you have any questions or require further assistance, please do not hesitate to reach out to us.
The combination of Doxylamine Succinate and Pyridoxine HCl in a slow-release formulation is commonly used to manage symptoms of nausea and vomiting during pregnancy, a condition known as morning sickness. Doxylamine is an antihistamine that can help reduce nausea and vomiting, while Pyridoxine, a form of vitamin B6, has been shown to improve symptoms of morning sickness. When considering the use of this combination therapy, it is important to be aware of potential drug interactions that may occur.
Doxylamine Succinate may interact with other central nervous system depressants, such as alcohol, benzodiazepines, opioids, and other antihistamines, potentially enhancing sedative effects. Caution is advised when patients are taking these medications concurrently. Additionally, monoamine oxidase inhibitors (MAOIs) can increase the anticholinergic effects of antihistamines, leading to an increased risk of side effects such as dry mouth, urinary retention, and constipation. It is generally recommended to avoid the use of MAOIs within two weeks of taking medications containing Doxylamine.
Pyridoxine HCl can interact with medications that affect vitamin B6 levels. For example, isoniazid, used to treat tuberculosis, can deplete vitamin B6 and may necessitate supplementation. Conversely, high doses of Pyridoxine can decrease the efficacy of levodopa, a medication used to treat Parkinson's disease, unless a dopa decarboxylase inhibitor is also being used. Additionally, Pyridoxine may reduce the effectiveness of phenobarbital and phenytoin, two antiepileptic drugs.
Since this formulation is designed to release the active ingredients slowly over time, it is important to consider that interactions may be prolonged or delayed. Patients should be advised not to crush or chew the capsules, as this could disrupt the controlled-release mechanism and potentially lead to a rapid release of the active ingredients, increasing the risk of side effects and interactions.
Patients should be encouraged to inform their healthcare providers of all medications, supplements, and herbal products they are currently taking to avoid potential interactions. Healthcare providers should review the patient's medication regimen for possible interactions before prescribing this slow-release formulation of Doxylamine Succinate and Pyridoxine HCl.

The Doxylamine Succinate 10 mg/Pyridoxine HCl 10 mg Slow Release (MEM4) Oral Capsules are a specialized pharmaceutical formulation designed to manage symptoms associated with certain conditions, such as nausea and vomiting during pregnancy. This formulation utilizes Methocel E4M, a hydrophilic matrix of hypromellose, which is a type of controlled-release polymer. When the capsule is ingested, the Methocel E4M swells upon contact with gastric fluids, forming a gel-like matrix that encapsulates the active ingredients, doxylamine succinate and pyridoxine HCl.
Doxylamine succinate is an antihistamine that works by blocking histamine receptors in the brain, which helps to reduce symptoms of nausea and vomiting. The combination of these two ingredients in a slow-release formulation ensures a steady absorption and prolonged effect, which can be particularly beneficial for managing symptoms that require consistent relief over time.
The slow-release mechanism of Methocel E4M is based on the principle of diffusion and erosion. As the gel matrix forms, it creates a barrier through which the active ingredients must diffuse to reach the bloodstream. This process is controlled by the rate at which the polymer matrix erodes and the drug dissolves. The result is a gradual and sustained release of doxylamine succinate and pyridoxine HCl, maintaining therapeutic levels in the body for an extended period. This reduces the need for frequent dosing, which can improve patient compliance and convenience, especially for patients experiencing discomfort due to frequent nausea and vomiting.
By using this controlled-release technology, the Doxylamine Succinate/Pyridoxine HCl Slow Release Capsules can provide a more consistent therapeutic effect, potentially leading to better management of symptoms and an overall improvement in the quality of life for patients. It is important for both patients and prescribers to understand the benefits and mechanisms of this formulation to ensure optimal use and adherence to the treatment regimen. If you have any questions or require further information about this formulation, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide the support and guidance you need.
