When does epocrates add new drug products?
New drug products are added to epocrates around the time the drug becomes commercially available to prescribe in the US.
Why are there separate drug monographs for brand names and generic names? How do these monographs differ?
epocrates provides monographs based on product-specific information, such as available formulations, dosing, indications, manufacturer, and pricing. For example, epocrates includes a unique monograph for each brand name albuterol inhaled product (i.e., ProAir HFA, ProAir RespiClick, Proventil HFA, Ventolin HFA), as well as a generic albuterol inhaled monograph. The generic monograph covers only the strengths and forms available on the US market as generic products. The brand name monographs are specific to each brand product.
Where can I find the indications/uses for a drug in epocrates?
FDA-approved indications and off-label uses (denoted by an asterisk) for prescription (Rx) drugs can be found under the Adult Dosing and Peds Dosing sections in epocrates drug monographs. Each bold header is an indication or use for the product, followed by appropriate dosing.
How do I use the weight-based dosing calculator?
On your mobile device, the epocrates weight-based dosing calculator can be found by tapping on the Calculators icon, then selecting “Dosing Calculator” under Popular. It can also be launched from the Dosing section of any drug monograph that contains weight-based dosing using the “Calculate Dose” link. Note that this is a general weight-based dosing calculator and is not specific to any given drug. Depending on the drug, the dosage may be expressed as a single dose (e.g., mcg/kg/dose, mg/kg/dose, etc.) or as a portion of a total daily dose (e.g., mg/kg/day divided into individual doses to be given at the appropriate frequency). You must select the appropriate units for your drug in this calculator. Doses can be calculated for Tablet/Capsule, Liquid, or Injection/Other forms.
Calculating Dose When Dosage is Expressed as Single Dose (“/dose”)
If the dosage is expressed in single doses (e.g., 2.2 mg/kg/dose PO q12h”), calculate the amount that will be given at each individual dose by entering the Dosage (in amt/kg/dose) and the patient’s weight. You do not need to input a frequency when calculating a single dose. The single dose calculated is to be given at the frequency specified in the drug’s dosing.
Calculating Dose When Dosage is Expressed as a Portion of a Total Daily Dose (“/day”)
If the dosage is expressed as a portion of a total daily dose (e.g., “25-45 mg/kg/day PO divided q12h”), calculate the amount that will be given at each individual dose by entering the total daily Dosage (in amt/kg/day), the patient’s weight, and the dosing frequency (i.e., the interval between doses, which will dictate into what equal portions the total daily dose will be divided). The calculated result will be displayed in terms of total daily dose (amt per day) and individual dose amount (amt per dose, to be given at the frequency that you entered).
Calculating Liquid Doses
If you wish the final dose to also be expressed in terms of volume of a liquid form, proceed as above and select “Liquid” as the Form. You will be prompted to input the concentration of the desired liquid form (in amt per mL). For instance, if the drug comes as a 250 mg/5 mL suspension, enter 250 mg on the first line and 5 mL on the second.
What is included in the Contraindications/Cautions section of a drug monograph?
The Contraindications/Cautions section includes diseases, conditions, and other circumstances in which the drug should not generally be used or should be used with caution, regardless of source or section in which it might appear in the prescribing information.
Where can I find drug allergy information in epocrates?
The contraindication “hypersens. to drug/class/compon.” is meant to globally convey that hypersensitivity to the drug, drug class, or the inactive ingredients is a contraindication for use. Epocrates drug monographs also include some specific clinically relevant allergens and cross-allergen risks in the Contraindications/Cautions section.
How is the Adverse Reactions section of epocrates drug monographs organized?
epocrates includes all adverse drug reactions (ADRs) and lab abnormalities reported in at least 2% of patients at any recommended dose for any indication and occurring more frequently in the treatment group than the placebo group. This may vary for products in which such information isn’t available, reported differently (e.g., listed as >1% or >5% in the product labeling), or studied versus an active control. Common Reactions also include any ADR referred to as “frequent,” “common,” or “most common” in the product labeling or primary literature.
If an ADR doesn’t meet our inclusion criteria as a serious or common ADR, but that ADR is nonetheless serious, severe, frequent, and/or is strongly associated with the use of the drug, it will be included at the end of the Common Reactions.
Common Reactions for prescription (Rx) drugs are usually listed in descending order of frequency. We may synthesize data from multiple sources and for multiple indications to arrive at an order that may differ from what appears in the drug's prescribing information for a single dose or indication.
For combination over-the-counter (OTC) products, Common Reactions are listed alphabetically.
Serious Reactions are included regardless of incidence. These effects are typically grouped by organ system or severity, but may sometimes be listed in other ways, such as alphabetically. The decision to include an effect as a Serious Reaction is based on its potential to cause death, result in significant morbidity or dependence/abuse, or require major medical intervention.
Does epocrates include incidence rates for adverse drug reactions (ADRs)?
Because data on the incidence of ADRs can be variable, inconsistent, and potentially misleading, we’ve chosen to list only the common adverse reactions in epocrates, in general descending order of frequency.
