Medication monitoring guidelines

The medication monitoring guidelines represent labs and monitoring that each provider should complete as a best practice if they are prescribing those medications/classes of medications.

Note: This is not an all-inclusive list.

Antipsychotics

Category/Drug Monitoring Type Timing Guidelines/Notes
All Antipsychotics Blood Pressure (BP) / Heart Rate (HR) At initiation; follow-up as clinically indicated Antipsychotics, especially atypical antipsychotics, can increase the risk of weight gain, high blood pressure, and other metabolic issues, which are significant risk factors for cardiovascular diseases.
AIMS or DISCUS At initiation; then annually (atypical) or bi-annually (typical) The AIMS serves as a standardized tool for early detection, monitoring, and management of TD, ensuring appropriate treatment and minimizing potential harm.
Height and Weight At initiation; then every 3 months Many antipsychotic medications can cause or exacerbate metabolic abnormalities like weight gain, glucose dysregulation, and hyperlipidemia. Weight gain is a component of metabolic syndrome, which significantly increases the risk of developing type 2 diabetes and cardiovascular disease.
Fasting Lipid Profile & HgA1c At initiation; at 4 months; then annually Metabolic monitoring is crucial when using antipsychotic medications due to their potential to cause metabolic side effects like weight gain, elevated blood sugar, and abnormal lipid levels. Regular monitoring helps identify and manage these risks early on. Refer to PCP for lipid management when indicated. 

Antidepressants

Category/Drug Monitoring Type Timing Guidelines/Notes
All SNRIs Blood Pressure Initiation, dose change, and annually By increasing norepinephrine, SNRIs can stimulate the sympathetic nervous system, which in turn can cause blood vessels to narrow (vasoconstriction) and heart rate to increase, leading to a rise in blood pressure 1
Creatinine Level At initiation Many SNRIs require dosage adjustments in patients with moderate or severe renal impairment to prevent drug accumulation and toxicity
Levomilnacipran ER (Fetzima) Creatinine Level At initiation and annually

Fetzima and its inactive metabolites are primarily eliminated from the body through renal (kidney) excretion. This means that kidney function directly impacts how efficiently the body clears the drug.

TLDR; changes in kidney function will require dose adjustments

Duloxetine (Cymbalta) Liver Function Tests (LFTs) As clinically indicated Duloxetine therapy can be associated with transient asymptomatic elevations in serum aminotransferase levels and has been linked to rare instances of clinically apparent acute liver injury
Mirtazapine (Remeron) and Tricyclic Antidepressants Weight At each visit for 1 year, then annually Increases appetite, potentially by blocking histamine H1 receptors and serotonin 5-HT2C receptors which normally suppress appetite. It can also shift metabolic processes towards carbohydrate preference and potentially induce insulin resistance.
Tricyclic Antidepressants EKG Before initiation of medication and with any report of symptoms suggestive of cardiac causes (chest pain, palpitations, SOB, syncope) TCAs may also induce cardiovascular complications, including arrhythmias such as QTc prolongation, ventricular fibrillation, and sudden cardiac death, particularly in individuals with preexisting ischemic heart disease. Therefore, assessing a patient's cardiac health is important before prescribing TCAs.


ADHD Medications

Category/Drug Monitoring Type Timing Guidelines/Notes
All Stimulants PDMP Check At initiation, with dose changes, at least twice annually

Follow state-specific requirements:

Blood Pressure / Heart Rate At baseline, with dose changes, and at least twice annually Cardiovascular monitoring
Cardiac Clearance/EKG At baseline (if clinically indicated)

Current clinical recommendations emphasize the need to assess the patient's personal and family cardiac history prior to initiation of ADHD pharmacotherapy, being vigilant about abnormal cardiovascular history (e.g., premature sudden/unexpected death in children or young adults, clinically important arrhythmias, prolonged QT syndrome, hypertrophic cardiomyopathy, and Marfan syndrome)8
 

EKG screening and cardiologist consultation are recommended for ADHD patients who have positive history of structural cardiac abnormalities

Weight At every visit (under age 16) Monitor for weight suppression
Height

Every 6 months (under age 16)


 

Most studies have concluded that while some effect on growth is apparent, discontinuation of treatment results in a rebound of growth to compensate for stimulant-induced loss in height. This is the basis for recommending “summer breaks”—when children forego stimulant treatment when on summer holiday from school 7
Strattera Blood Pressure / Heart Rate At initiation, with dose increases, and every 6 months Monitor cardiovascular effects
Cardiac Evaluation At baseline (if clinically indicated) If cardiac risk factors are present
Liver Function Tests (LFTs) As clinically indicated Consider if symptoms or concerns about liver function arise
Weight At every visit (under age 16) Monitor for weight suppression


Mood Stabilizers

Category/Drug Monitoring Type Timing Guidelines/Notes
Depakote HCG / Pregnancy Test Obtain negative pregnancy test prior to medication initiation in women of childbearing age

Strongly recommend avoiding prescribing to women of childbearing age

First trimester use of valproate has been associated with a 3-5% risk of neural tube defects, as well as an increased risk of other malformations affecting the heart, limbs, and genitals. Prenatal exposure to valproate may also result in lower IQ and increased risk of autism spectrum disorders in the offspring 2

Weight At each visit for 1 year, then annually Monitor for weight gain
CBC w/ Diff, LFTs, Valproate Level 1 month after start, 6 months after, then annually Monitor for hepatotoxicity, thrombocytopenia, and therapeutic level
Tegretol (carbamazepine)8 Weight At each visit for 1 year, then annually (if not done elsewhere in 2 mo) Weight gain is a common and frequent undesirable effect associated with the use of anticonvulsant drugs
CBC w/ Diff, LFTs, UA, BUN/Cr Baseline Baseline labs for safety monitoring
CBC w/ Diff, LFTs, BUN/Cr, Na+ 2 weeks after start/dose change, 6 months after, then annually Na+ monitoring if symptomatic (hyponatremia risk)
HLA-B*1502 allele screening

Prior to prescribing (if possibility of HLA‑B*15:02 allele)

Do not prescribe if allele is present (risk of Stevens-Johnson Syndrome)


 

HLA‑B*15:02, a specific allele common in several East and Southeast Asian populations, dramatically increases the risk of Stevens–Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) when drugs like carbamazepine are prescribed—especially without genetic screening 6

Do not prescribe if allele is present (risk of Stevens-Johnson Syndrome)

Ophthalmic Exam As clinically indicated Consider if visual symptoms present
Tegretol Level As clinically indicated Consider with symptom change, pregnancy, or toxicity concerns
Lithium Lithium Level Weekly until therapeutic range is achieved, then 1 month after to confirm, then every 6 - 12 months following stable range for monitoring Monitor serum levels closely to avoid toxicity and ensure therapeutic dosing; draw blood ~12 hours after last dose (trough level) 4
Weight Each visit for 1 year, then annually Monitor for weight changes
CBC, BUN/Creatinine, TSH, UA, pregnancy test Baseline Assess overall health before starting lithium
BMP, TSH After 1 month, then every 6-12 months after Monitor to detect early dysfunction or side effects

Topamax/

topiramate

BMP, UA with micro Baseline, 3 months, 6 months, then annually Monitor renal function and electrolytes; watch for metabolic acidosis and kidney stones risk


Substance Use Deterrents

Category/Drug Monitoring Type Timing Guidelines/Notes
Naltrexone (Vivitrol) Liver Function Tests (LFTs) Baseline, 3 months, 6 months, then annually While naltrexone is generally considered safe, it can cause asymptomatic elevations in liver enzymes, and checking LFTs helps identify and manage any potential issues early on  11
Disulfiram (Antabuse) LFTs and Renal Function Baseline Baseline labs before starting treatment
LFTs Monthly for first 6 months, then annually Close monitoring during initial treatment 10
