What are the possible side effects of Swithro 200?
Get emergency medical help if you have signs of an allergic reaction to Swithro 200: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
In rare cases, Swithro 200 may cause a severe skin reaction that can be fatal if it spreads to other parts of the body. Seek medical treatment if you have a new or worsening skin rash with fever, swollen glands, flu symptoms, or severe tingling or numbness.
Call your doctor at once if you have:
severe stomach pain, diarrhea that is watery or bloody;
headache with chest pain and severe dizziness, fainting, fast or pounding heartbeats;
liver problems - nausea, upper stomach pain, itching, tired feeling, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes); or
severe skin reaction - fever, sore throat, swelling in your face or tongue, burning in your eyes, skin pain followed by a red or purple skin rash that spreads (especially in the face or upper body) and causes blistering and peeling.
Older adults may be more likely to have side effects on heart rhythm, including a life-threatening fast heart rate.
Common Swithro 200 side effects may include:
nausea, vomiting, stomach pain; or
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Side effects of Swithro 200 in details
A side effect of any drug can be defined as the unwanted or undesired effect produced by the drug. The side effect can be major or in few medications minor that can be ignored. Side effects not only vary from drug to drug, but it also depends on the dose of the drug, the individual sensitivity of the person, brand or company which manufactures it. If side effects overweigh the actual effect of the medicine, it may be difficult to convince the patient to take the drug. Few patients get specific side effects to specific drugs; in that case, a doctor replaces the drug with another. If you feel any side effect and it troubles you, do not forget to share with your healthcare practitioner.
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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In clinical trials, most of the reported adverse reactions were mild to moderate in severity and were reversible upon discontinuation of the drug. Approximately 0.7% of the patients from the multiple-dose clinical trials discontinued Swithro 200 therapy because of treatment-related adverse reactions. Serious adverse reactions included angioedema and cholestatic jaundice. Most of the adverse reactions leading to discontinuation were related to the gastrointestinal tract, e.g., nausea, vomiting, diarrhea, or abdominal pain.
Overall, the most common adverse reactions in adult patients receiving a multiple-dose regimen of Swithro 200 were related to the gastrointestinal system with diarrhea/loose stools (5%), nausea (3%), and abdominal pain (3%) being the most frequently reported.
No other adverse reactions occurred in patients on the multiple-dose regimen of Swithro 200 with a frequency greater than 1%. Adverse reactions that occurred with a frequency of 1% or less included the following:
Cardiovascular:Palpitations and chest pain.
Gastrointestinal:Dyspepsia, flatulence, vomiting, melena, and cholestatic jaundice.
Genitourinary:Monilia, vaginitis, and nephritis.
Nervous System:Dizziness, headache, vertigo, and somnolence.
Allergic:Rash, photosensitivity, and angioedema.
Chronic therapy with 1200 mg weekly regimen
The nature of adverse reactions seen with the 1200 mg weekly dosing regimen for the prevention of Mycobacterium avium infection in severely immunocompromised HIV-infected patients were similar to those seen with short-term dosing regimens.
Chronic therapy with 600 mg daily regimen combined with ethambutol
The nature of adverse reactions seen with the 600 mg daily dosing regimen for the treatment of Mycobacterium avium complex infection in severely immunocompromised HIV-infected patients were similar to those seen with short term dosing regimens. Five percent of patients experienced reversible hearing impairment in the pivotal clinical trial for the treatment of disseminated MAC in patients with AIDS. Hearing impairment has been reported with macrolide antibiotics, especially at higher doses. Other treatment-related adverse reactions occurring in > 5% of subjects and seen at any time during a median of 87.5 days of therapy include: abdominal pain (14%), nausea (14%), vomiting (13%), diarrhea (12%), flatulence (5%), headache (5%), and abnormal vision (5%). Discontinuations from treatment due to laboratory abnormalities or adverse reactions considered related to study drug occurred in 8 of 88 (9.1%) of subjects.
The following adverse reactions have been identified during post approval use of Swithro 200. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Adverse reactions reported with Swithro 200 during the postmarketing period in adult and/or pediatric patients for which a causal relationship may not be established include:
Allergic:Arthralgia, edema, urticaria, and angioedema.
Cardiovascular:Arrhythmias, including ventricular tachycardia, and hypotension. There have been reports of QT prolongation and torsades de pointes.
Nervous System:Convulsions, dizziness/vertigo, headache, somnolence, hyperactivity, nervousness, agitation, and syncope.
Psychiatric:Aggressive reaction and anxiety.
Skin/Appendages:Pruritus, and serious skin reactions including erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and DRESS.
Special Senses:Hearing disturbances including hearing loss, deafness, and/or tinnitus, and reports of taste/smell perversion and/or loss.
Significant abnormalities (irrespective of drug relationship) occurring during the clinical trials were reported as follows:
With an incidence of 1 to 2%, elevated serum creatine phosphokinase, potassium, ALT (SGPT), GGT, and AST (SGOT).
With an incidence of less than 1%, leukopenia, neutropenia, decreased platelet count, elevated serum alkaline phosphatase, bilirubin, BUN, creatinine, blood glucose, LDH, and phosphate.
When follow-up was provided, changes in laboratory tests appeared to be reversible.
In multiple-dose clinical trials involving more than 3000 patients, 3 patients discontinued therapy because of treatment-related liver enzyme abnormalities and 1 because of a renal function abnormality.
In a phase 1 drug interaction study performed in normal volunteers, 1 of 6 subjects given the combination of Swithro 200 and rifabutin, 1 of 7 given rifabutin alone, and 0 of 6 given Swithro 200 alone developed a clinically significant neutropenia (< 500 cells/mm3).
Laboratory abnormalities seen in clinical trials for the prevention of disseminated Mycobacterium avium disease in severely immunocompromised HIV-infected patients.
Chronic therapy (median duration: 87.5 days, range: 1 to 229 days) that resulted in laboratory abnormalities in > 5% of subjects with normal baseline values in the pivotal trial for treatment of disseminated MAC in severely immunocompromised HIV-infected patients treated with Swithro 200 600 mg daily in combination with ethambutol include: a reduction in absolute neutrophils to < 50% of the lower limit of normal (10/52, 19%) and an increase to five times the upper limit of normal in alkaline phosphatase (3/35, 9%). These findings in subjects with normal baseline values are similar when compared to all subjects for analyses of neutrophil reductions (22/75, 29%) and elevated alkaline phosphatase (16/80, 20%). Causality of these laboratory abnormalities due to the use of study drug has not been established.
