Metformin—there is a risk of lactic acidosis when using this drug. Discontinue die drug therapy and notify the health care provider immediately if any of the following should occur respiratory distress, muscular aches, unusual somnolence, unexplained malaise, or nonspecific abdominal distress. 

Cyclosporine and tacrolimus are calcineurin inhibitors that are administered as part of immunosuppressive regimens in kidney, liver, heart, lung, and bone marrow transplant recipients. In addition, they are used in autoimmune disorders such as psoriasis and multiple sclerosis. The pathophysiologic mechanism for ARF is renal vascular vasoconstriction.41 It often occurs within the first 6 to 12 months of treatment, and can be reversible with dose reduction or drug discontinuation. Risk factors include high dose, elevated trough blood concentrations, increased age, and concomitant therapy with other nephrotoxic drugs.41 Cyclosporine and tacrolimus are extensively metabolized by... 

Carbamazepine Manufacturer recommends CBC and platelets (and possibly reticulocyte counts and serum iron) at baseline, and that subsequent monitoring be individualized by the clinician (e.g., CBC, platelet counts, and liver function tests every 2 weeks during the first 2 months of treatment, then every 3 months if normal). Monitor more closely if patient exhibits hematologic or hepatic abnormalities or if the patient is receiving a myelotoxic drug discontinue if platelets are less than 100,000/mm3, if white blood cell (WBC) count is less than 3,000/mm3 or if there is evidence of bone marrow suppression or liver dysfunction. Serum electrolyte levels should be monitored in the elderly or those at risk for hyponatremia. Carbamazepine interferes with some pregnancy tests.

If you do decide to discontinue drug treatment, talk to your doctor first. It will be important to taper your medication gradually, rather than stopping abruptly. The book Coming Off Antidepressants by Joseph Glenmullen of the Harvard Medical School is an excellent source of information on how to discontinue antidepressant drug treatment.

Systemic corticosteroids (e.g., oral prednisone 1 mg/kg/day tapered over 3 weeks) is more effective for these patients. 

Several case reports of hepatotoxicity with pioglitazone or rosiglitazone have been reported, but improvement in alanine aminotransferase (ALT) was consistently observed upon drug discontinuation. Baseline ALT should be obtained prior to therapy and then periodically thereafter at the practitioner s discretion. Neither drug should be started if the baseline ALT exceeds 2.5 times the upper limit of normal. The drugs should be discontinued if the ALT is more than 3 times the upper limit of normal. 

Patients with panic disorder should be seen every 2 weeks during the first few weeks to adjust medication doses based on symptom improvement and to monitor side effects. Once stabilized, they can be seen every 2 months. The Hamilton Rating Scale for Anxiety (score less than or equal to 7 to 10) can be used to measure anxiety, and the Sheehan Disability Scale (with a goal of less than or equal to 1 on each item) can be used to measure for disability. During drug discontinuation, the frequency of appointments should be increased. 

Responders to drug therapy should continue treatment for at least 12 months. When discontinued, drug therapy should be tapered slowly over a period of 1 month or more to reduce the likelihood of relapse. 

Allergic reactions are rare and usually occur within 8 weeks of initiating therapy. They manifest as maculopapular, erythematous, or pruritic rashes. Drug discontinuation and topical steroids are recommended when they occur. 

The reasons for drug attrition have evolved over the years over the last decade, lack of safety (both non-clinical and clinical) remains the major cause of attrition during clinical development, which accounts for approximately 35 to 40% of all drug discontinuation (see Table 13.1).la lc More worrying is the fact that there is no clear trend toward a reduction of the attrition owing to safety reasons.
