As suicidal ideation and behavior in clinical trials are rare, the results for any drug taken separately usually do not reach statistical significance. In the United States FDA released a public health advisory noting that there had been 11 reports of suicide attempts and 3 reports of suicidality within the mostly middle-aged women participating in the open label extension trials of duloxetine for the treatment of stress urinary incontinence.
The FDA described the potential role of confounding social stressors "unclear". The suicide attempt rate in the SUI study population based on 9, patients was calculated to be per , person years. This rate is greater than the suicide attempt rate among middle-aged U. In addition, one death from suicide was reported in a Cymbalta clinical pharmacology study in a healthy female volunteer without SUI.
No increase in suicidality was reported in controlled trials of Cymbalta for depression or diabetic neuropathic pain. Duloxetine plasma concentrations may be increased significantly by some antidepressants, quinidine, and quinolone antibiotics. Duloxetine may increase the plasma concentrations of other antidepressants, antipsychotics, and type 1C antiarrhythmics such as propafenone Rythmol and flecainide Tambocor. Serum alanine transaminase levels increased to more than three times the upper limit of normal in about 1 percent of patients taking duloxetine in placebo-controlled trials 2 ; alcohol may increase this risk.
However, there have been no reports of hepatic failure. Duloxetine is not recommended in patients with end-stage renal disease or severe renal impairment because of the increased plasma concentrations of the drug and its metabolites.
Duloxetine is FDA pregnancy category C based on negative animal studies; there have been no trials assessing its use in pregnant women. Many believe the pain is due to changes in the nervous system which cause nerve cells to fire off too many signals along pain pathways.
This makes a person overly sensitive to things that would normally not be painful. Researchers think that Cymbalta helps calm down these pain signals by increasing the level of two naturally occurring substances called serotonin and norepinephrine. These substances, which are found in the brain and other parts of the nervous system, can affect mood and are believed to help control and suppress feelings of pain.
Cymbalta and other SNRIs block serotonin and norepinephrine from re-entering cells, and therefore increase the levels of these substances. This process is thought to improve mood and relieve pain in patients with fibromyalgia. How Do You Take Cymbalta? Cymbalta is a capsule that you take by mouth once a day. Prescriptions for CYMBALTA should be written for the smallest quantity of capsules consistent with good patient management, in order to reduce the risk of overdose.
Screening Patients For Bipolar Disorder A major depressive episode may be the initial presentation of bipolar disorder. Whether any of the symptoms described above represent such a conversion is unknown. However, prior to initiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression.
These cases have presented as hepatitis with abdominal pain, hepatomegaly , and elevation of transaminase levels to more than twenty times the upper limit of normal with or without jaundice , reflecting a mixed or hepatocellular pattern of liver injury. CYMBALTA should be discontinued in patients who develop jaundice or other evidence of clinically significant liver dysfunction and should not be resumed unless another cause can be established.
Cases of cholestatic jaundice with minimal elevation of transaminase levels have also been reported. Other postmarketing reports indicate that elevated transaminases, bilirubin, and alkaline phosphatase have occurred in patients with chronic liver disease or cirrhosis.
Liver transaminase elevations resulted in the discontinuation of 0. In most patients, the median time to detection of the transaminase elevation was about two months. Syncope and orthostatic hypotension tend to occur within the first week of therapy but can occur at any time during CYMBALTA treatment, particularly after dose increases.
The risk of falling appears to be related to the degree of orthostatic decrease in blood pressure as well as other factors that may increase the underlying risk of falls. In an analysis of patients from all placebo-controlled trials, patients treated with CYMBALTA reported a higher rate of falls compared to patients treated with placebo. Risk appears to be related to the presence of orthostatic decrease in blood pressure. As elderly patients tend to have a higher underlying risk for falls due to a higher prevalence of risk factors such as use of multiple medications, medical comorbidities and gait disturbances, the impact of increasing age by itself is unclear.
Serotonin Syndrome The development of a potentially life-threatening serotonin syndrome has been reported with SNRIs and SSRIs, including CYMBALTA, alone but particularly with concomitant use of other serotonergic drugs including triptans, tricyclic antidepressants , fentanyl, lithium , tramadol, tryptophan , buspirone, amphetamines, and St.
Serotonin syndrome symptoms may include mental status changes e. Patients should be monitored for the emergence of serotonin syndrome. No reports involved the administration of methylene blue by other routes such as oral tablets or local tissue injection or at lower doses. If concomitant use of CYMBALTA with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, buspirone, tryptophan, amphetamines, and St.
Any advice would be greatly appreciated. God bless you and keep you safe always. Read More I don't understand that. If they're at a loss for answers, then what's the harm to give me a test for it? I also have other issues and have been sick going on 2 yrs. I've lost trust in the medical profession. My son is now 31 but when he was a toddler I noticed that he was hungry a lot and ate a lot but was losing weight.
I took him to the doctor and they really didn't do anything.
