Formula Information

A small arrow pointing down

Phenobarbital 20 mg/ml Oral Liquid is a specially compounded medication designed for ease of administration and precise dosing. This formulation is particularly beneficial for patients who have difficulty swallowing pills, such as young children or elderly individuals. The liquid form allows for flexible dosing, which can be adjusted according to the specific needs of the patient. Phenobarbital, the active ingredient, is a long-acting barbiturate that is commonly used to manage various conditions, including epilepsy and seizures. It works by decreasing the activity of the brain and nervous system, thereby reducing the frequency and severity of seizures.

It may also be used in emergency situations for the acute treatment of convulsions. In addition to its anticonvulsant properties, Phenobarbital has sedative and hypnotic effects, which can be beneficial in managing anxiety and promoting sleep in patients with certain medical conditions. However, due to its potential for dependence and tolerance, its use must be carefully monitored by healthcare professionals.

For prescribers considering Phenobarbital 20 mg/ml Oral Liquid, it is important to note that dosing should be individualized based on the patient's response and the specific condition being treated. Regular monitoring of blood levels may be necessary to ensure therapeutic effectiveness and to avoid toxicity. Patients should be counseled on the potential side effects of Phenobarbital, which can include drowsiness, dizziness, and cognitive impairment, among others. It is also crucial to discuss the risk of withdrawal symptoms if the medication is discontinued abruptly.

Bayview Pharmacy is committed to providing high-quality compounded medications to meet the unique needs of each patient. Our team of knowledgeable compounding pharmacists is available to answer any questions and provide guidance on the use of Phenobarbital 20 mg/ml Oral Liquid. We work closely with prescribers to ensure optimal therapeutic outcomes for our patients. If you have any questions or require further information about this formulation, please do not hesitate to reach out to us.

Drug Interactions

A small arrow pointing down

Phenobarbital is a long-acting barbiturate that is commonly used as a sedative and an anticonvulsant. It works by depressing the central nervous system, which can help to control seizures and provide sedative effects. When considering the use of phenobarbital 20 mg/ml oral liquid, it is important to be aware of potential drug interactions that may affect the efficacy of the medication or increase the risk of adverse effects.

Phenobarbital can interact with a wide range of medications due to its effects on liver enzymes. It is a potent inducer of cytochrome P450 enzymes, particularly CYP2C9 and CYP3A4, which can lead to decreased plasma concentrations and reduced efficacy of drugs metabolized by these enzymes. Examples include warfarin, certain antiepileptics (like phenytoin and valproate), and oral contraceptives. Patients taking these medications may require dosage adjustments and close monitoring when starting or stopping phenobarbital.

Conversely, drugs that inhibit these enzymes may increase phenobarbital levels, potentially leading to toxicity. Caution is advised when combining phenobarbital with inhibitors of CYP2C9 and CYP3A4. Additionally, phenobarbital may enhance the metabolism of vitamin D and vitamin K, necessitating monitoring of vitamin levels and supplementation if necessary.

Phenobarbital's CNS depressant effects can be additive with other CNS depressants, such as alcohol, opioids, antihistamines, and benzodiazepines. This can increase the risk of respiratory depression, sedation, and even coma. Patients should be counseled to avoid alcohol and be cautious with other CNS depressants while taking phenobarbital.

Furthermore, phenobarbital may reduce the effectiveness of corticosteroids and doxycycline due to increased metabolism. It can also affect the anticoagulant effects of anticoagulant drugs, requiring close monitoring of INR levels in patients taking these medications concurrently.

It is also important to note that abrupt discontinuation of phenobarbital, especially after long-term use, can lead to withdrawal symptoms and rebound seizures in patients with epilepsy. Gradual tapering is recommended to minimize these risks.

Given the potential for significant drug interactions, it is crucial for prescribers to review a patient's complete medication profile before initiating treatment with phenobarbital oral liquid. Patients should be advised to inform their healthcare providers of all medications they are taking, including over-the-counter drugs and herbal supplements. For any questions or concerns regarding drug interactions with phenobarbital, please reach out to us at Bayview Pharmacy for professional advice and guidance.

How Does it Work

A small arrow pointing down

The Phenobarbital 20 mg/ml Oral Liquid is a specially compounded medication designed for ease of administration and precise dosing. Phenobarbital, the active ingredient in this formulation, is a long-acting barbiturate that exerts its effect by depressing the central nervous system, particularly affecting the brain's inhibitory neurotransmitter gamma-aminobutyric acid (GABA). By enhancing the action of GABA, phenobarbital increases its inhibitory effects and thereby stabilizes neuronal activity. This mechanism is crucial in the treatment of various disease states, primarily epilepsy and seizures.

In epilepsy, phenobarbital helps to prevent the abnormal electrical activity in the brain that causes seizures. Additionally, phenobarbital is sometimes used for its sedative and hypnotic properties in the management of anxiety and insomnia, although these uses are less common due to the development of newer medications with fewer side effects.

The oral liquid formulation is particularly beneficial for patients who have difficulty swallowing pills, such as young children, the elderly, or those with neurological disorders that impair swallowing. The liquid form allows for flexible dosing, which is essential for pediatric patients whose doses often need to be adjusted based on weight. Moreover, the 20 mg/ml concentration facilitates the administration of precise doses without the need for splitting or crushing tablets, ensuring that patients receive the exact amount of medication prescribed by their healthcare provider.

Regular monitoring by a healthcare professional is necessary to ensure the optimal therapeutic outcome and to minimize any adverse effects. Additionally, phenobarbital can interact with a variety of other medications, so it is crucial to inform the prescriber of all other drugs being taken.

For any questions regarding the Phenobarbital 20 mg/ml Oral Liquid formulation, or to discuss its appropriateness for specific patients or disease states, please do not hesitate to reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is dedicated to providing the highest level of care and expertise.

Enter the formula as a compound

Compounded preparations have no NDC, so this formula will not appear in your EHR's drug search. Use your system's compound, non-formulary, or free-text prescription entry and name the preparation exactly as written in step 3. If your EHR forces you to pick a listed drug, pick the closest entry for the active ingredient and put the full formula in the prescription body (the Sig or directions field), not in Notes to Pharmacy.

Compounded preparations have no NDC and will not appear in your drug search. For EPCS to validate, select a drug entry your EHR recognizes as controlled, usually the bulk powder entry for the active ingredient (for example Ketamine (bulk) powder, not a branded product), then put the full formula from step 3 in the prescription body. A free-text entry that does not validate as controlled will be rejected by your EPCS module.
