FOR BIPOLAR DISORDER
NOW Bipolar Pharmacotherapy Safety Concerns and Recommended Monitoring
Common Side Effects
Fine hand tremor, thirst, polyuria, nausea, diarrhea, weight gain Less Common, Potential y
Nephrotoxicity, teratogenicity, neurotoxicity (serum level related) Serious Side Effects
Early Signs of Lithium Toxicity
New onset of diarrhea, vomiting, drowsiness, muscular weakness, lack of coordination Long-term Concerns Require
Decreased thyroid function, nephrotoxicity Monitoring
Baseline Evaluations
BUN, creatinine; thyroid function; serum pregnancy test or assessment Monitoring
• 12 hrs post dose serum lithium level for monitoring; 5 to 7 days after initiating treatment and after each dose change (2 levels to establish therapeutic dose); then every 6 months • TSH, Ca2+, and weight after 6 months, then annual y Comments
• Monitoring lithium levels and creatinine every 6 months minimizes the risk associated • Obtain a lithium level if there is a concern about lithium toxicity, as indicated by new findings of nausea, diarrhea, or change in tremor in someone previously stable on lithium • Be alert to signs of possible hypothyroid disorder, as indicated by increased weight, cold intolerance, or fatigue in someone stabilized on lithium treatment • Recheck lithium levels if any diuretic medications are started or adjusted • Long term lithium use may result in hyperparathyroidism and elevated Ca2+ levels; thus DIVALPROEX/VALPROIC ACID
Common Side Effects
GI symptoms, weight gain, headache, fatigue, dizziness, tremor Less Common, Potential y
Teratogenicity, pancreatitis, polycystic ovary syndrome (in young women), Serious Side Effects
Baseline Evaluations
• Initial CBC + platelets, LFTs: be aware of bleeding during first 6 months Monitoring
• Weigh initial y more often, then every 6 months Comments
• Reinforce the importance of avoiding pregnancy for female patients • Many potential y important drug-drug interactions. Tends to increase serum level of other w w w . N O W B i p o l a r . o r g

CARBAMAZEPINE
Common Side Effects
Dizziness, drowsiness, unsteadiness, nausea, vomiting Less Common, Potential y
Serious, but very rare dermatological reactions (Stevens-Johnson syndrome, toxic Serious Side Effects
epidermal necrolysis), teratogenicity, agranulocytosis, neutropenia Baseline Evaluations
• HLA-B*1502 genotype screening in patients of Asian descent (screen for increased genetic risk of Stevens-Johnson syndrome) Monitoring
• Alert to signs of rash early in treatment course • CBC, platelets, LFTs, serum sodium every 6 months Comments
• Many important drug-drug interactions. Can significantly decrease serum levels of many medications, including decreased ef ectiveness of many contraceptives • Reinforce the importance of contraception for female patients LAMOTRIGINE
Common Side Effects
General y wel tolerated: initial nausea, dizziness, somnolence, headache sometimes Less Common, Potential y
• Serious dermatological reactions (Stevens-Johnson syndrome, toxic epidermal Serious Side Effects
necrolysis) much more frequent if medication is started at ful dose rather than increased very slowly over time; use standard titration protocol or prepackaged "start-up" packs Monitoring
• Alert to signs of rash early in treatment: especial y of mucosal membranes, palmar surfaces, contiguous rash over upper chest and face Comments
• If medication is discontinued > 3 days, must be restarted with same slow taper as with w w w . N O W B i p o l a r . o r g
