This is not a complete list of all possible side effects. Contact your healthcare provider if you experience any unexpected symptoms. For serious or life-threatening side effects, seek emergency medical attention immediately.
6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Myelosuppression [see Warnings and Precautions (5.1) ] Interstitial Lung Disease [see Warnings and Precautions (5.2) ] Extravasation and Tissue Injury [see Warnings and Precautions (5.3) ] The most common Grade 3 or 4 hematologic adverse reactions (incidence >5%) were: neutropenia , anemia , thrombocytopenia, and febrile neutropenia.
( 6.1 ) The most common non-hematologic adverse reactions (incidence >5%) (all grades) were asthenia, dyspnea, nausea, pneumonia, abdominal pain, and fatigue.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The data in Warnings and Precautions reflect exposure to topotecan from 8 trials in which 879 patients with small cell lung cancer (SCLC) and other solid tumors received topotecan 1.5 mg/m 2 by intravenous infusion daily for 5 consecutive days, starting on Day 1 of a 21-day cycle.
Small Cell Lung Cancer (SCLC) The safety of topotecan was evaluated in randomized, comparative trial in patients with recurrent or progressive SCLC (Study 090) [see Clinical Studies (14.1) ].
Table 1 shows the Grade 3 or 4 hematologic and non-hematologic adverse reactions in patients with SCLC.
Adverse Reactions Occurring in ≥5% of Patients with Small Cell Lung Cancer in Study 090 Adverse Reactions Topotecan (n = 107) CAV CAV = cyclophosphamide, doxorubicin and vincristine.

5 WARNINGS AND PRECAUTIONS Interstitial lung disease (ILD): Fatal cases have occurred.
Permanently discontinue if ILD confirmed.
( 5.2 ) Extravasation and tissue injury : Severe cases have occurred.
If extravasation occurs, immediately stop administration and institute recommended management procedures.
( 5.3 ) Embryo-fetal toxicity : Can cause fetal harm.
Like all medications, Topotecan can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
