What Is Bipolar Disorder?

PREPARATIONS:

  • Tablets: 300 mg.
  • Tablets (extended release): 300 and 450 mg.
  • Capsules: 150, 300 and 600 mg.
  • Syrup: 300 mg/5 ml

DRUG INTERACTIONS:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs), (for example, ibuprofen [Motrin, Advil], naproxen [Naprosyn, Aleve], indomethacin [Indocin], nabumetone [Relafen], diclofenac [Voltaren, Cataflam, Arthrotec], ketorolac [Toradol]), reduce the kidney's ability to eliminate lithium and lead to elevated levels of lithium in the blood andside effects from lithium. Blood concentrations of lithium may need to be measured for 4 to 7 days after an NSAID is either added or stopped during lithium therapy. Aspirin and sulindac (Clinoril) do not appear to affect lithium concentrations in the blood.
  • Diuretics (water pills) should be used cautiously in patients receiving lithium. Diuretics that act at the distal renal tubule, (for example, hydrochlorothiazide [Hydrodiuril], spironolactone [Aldactone], triamterene [Dyrenium; Dyazide, Maxzide]), can increase blood concentrations of lithium. Diuretics that act at the proximal tubule, (for example, acetazolamide [Diamox]), are more likely to reduce blood concentrations of lithium. Diuretics such as furosemide (Lasix) and bumetanide (Bumex) may have no affect on lithium concentrations in blood.
  • ACE inhibitors, (for example, enalapril [Vasotec], lisinopril [Zestril, Prinivil], benazepril [Lotensin], quinapril [Accupril], moexipril [Univasc], captopril [Capoten], ramipril [Altace]), may increase the risk of developing lithium toxicity by increasing the amount of lithium that is reabsorbed into the body in the tubules of the kidney and thereby reducing the excretion of lithium.
  • When carbamazepine (Tegretol) and lithium are used together, some patients may experience side effects, including dizziness, lethargy, and tremor. Central nervous system side effects also may occur when lithium is used with antidepressants, (for example, fluoxetine [Prozac] sertraline [Zoloft], and paroxetine [Paxil], fluvoxamine [Luvox], amitriptyline [Elavil], imipramine [Tofranil], desipramine [Norpramin]). Combining lithium with monoamine oxidase inhibitor (MAOI) class of antidepressants (for example, isocarboxazid [Marplan], phenelzine [Nardil], tranylcypromine [Parnate], selegiline [Eldepryl], and procarbazine [Matulane]) or other drugs that inhibit monoamine oxidase (for example, linezolid [Zyvox]) may lead to serious reactions.
  • Medications which cause the urine to become alkaline (the opposite of acidic) can increase the amount of lithium that is lost into the urine. This results in lower blood concentrations of lithium and reduces the effects of lithium. Such drugs include potassium acetate, potassium citrate (Urocit-K), sodium bicarbonate, and sodium citrate (Bicitra, Cytra-2, Liqui-Citra, Oracit, Shohl's).
  • Caffeine appears to reduce serum lithium concentrations, and side effects of lithium have increased in frequency when caffeine is consumed.
  • Both diltiazem (Cardizem-CD, Tiazac, Dilacor-XR) and verapamil (Calan-SR, Isoptin-SR, Verelan, Covera-HS) have been reported to have variable effects on lithium levels in blood. In some patients there may be decreased lithium blood levels and in others lithium toxicity.
  • Methyldopa (Aldomet) may increase the likelihood of lithium toxicity.
  • Various reactions have resulted when lithium is administered with phenothiazines, (for example, chlorpromazine [Thorazine], thioridazine [Mellaril], trifluoperazine [Stelazine] or with haloperidol [Haldol]). Such reactions have included delirium, seizures, encephalopathy, high fever or certain neurologic reactions that affect movement of muscles, called extrapyramidal symptoms.
  • Lithium can cause goiter or hypothyroidism. The use of lithium with potassium iodide can increase the likelihood of this adverse reaction.
  • The use of the beta blocker, propranolol (Inderal), with lithium can lead to a slow heart rate and dizziness. Other beta blockers, (for example, metoprolol [Lopressor], atenolol [Tenormin]) also may interact with lithium and be associated with a slow heart rate.
