prior intravesical therapy completed 4 weeks prior to enrollment and adjuvant/neoadjuvant chemotherapy completed more than 6 months prior to diagnosis of advanced disease are permitted~* Zubrod performance status =\< 2 (Karnofsky \>= 60%)~* Life expectancy of greater than 3 months~* Leukocytes \>= 3,000/mcL~* Absolute neutrophil count \>= 1,500/mcL~* Platelets \>= 100,000/mcL~* Total bilirubin \< 1.5 times the upper limit of normal (x ULN) for the institution~* Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 3 x institutional upper limit of normal~* Creatinine clearance; calculated creatinine clearance (CrCl) \>= 30 mL/min and \< 60 mL/min (Cockroft-Gault) unless the patient qualified based on hearing loss or neuropathy~* Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of gemcitabine and eribulin administration~* Ability to understand and the willingness to sign a written informed consent document~Exclusion Criteria:~* Patients with a small cell component in their histology are excluded~* Patients who have had chemotherapy for the treatment of the advanced or unresectable urothelial cancer of the bladder are not eligible; patients who were previously treated for local disease must not have received radiotherapy or chemotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study and must have recovered from adverse events due to agents administered more than 4 weeks earlier; patients who have received neoadjuvant or adjuvant chemotherapy must have completed treatment at least 6 months prior to diagnosis of metastatic disease~* Patients who are receiving any other investigational agents~* Patients with known brain metastases should be excluded from this clinical trial~* History of allergic reactions attributed to compounds of similar chemical or biologic composition to gemcitabine and eribulin~* Uncontrolled intercurrent illness including, but not limited to, a second cancer diagnosis within the past 5 years, or a cancer undergoing any treatment, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements~* Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with eribulin and gemcitabine~* Human immunodeficiency virus (HIV)-positive patients with inadequate cluster of differentiation (CD)4 counts or those who are on combination antiretroviral therapy with strong cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) effects are ineligible for this trial~* Patients with baseline corrected QT (QTc) prolongation greater than grade 1 are excluded from this study; patients with grade 1 QTc elevation are eligible but must be monitored with electrocardiogram (ECG) (EKG) exams, for the first 3 cycles of treatment; eribulin time to maximum concentration (Cmax) after infusion is about 10 minutes, and half life is 40 minutes; ECG (EKG) should be performed between 10 to 40 minutes after eribulin administration (on day 1 and day 8 of treatment); continued ECG (EKG) monitoring beyond cycle 3 can be done at the discretion of the treating physician~* Patients with congenital long QT syndrome are excluded from this study~* Other medications known to prolong QT interval should be discontinued and if not possible, patient is excluded from this study

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Treatment (eribulin mesylate and gemcitabine hydrochloride) (Type: EXPERIMENTAL): Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 and eribulin mesylate IV over 2-5 minutes on days 1 and 8. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
