Disease interactions
21 potential interactions Applies to: 20 conditions, including Seizures, Arrhythmia, Psoriasis, Hypoglycemia, and Myasthenia Gravis.
Alcoholism
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Alcoholism.
Aminoquinolines may concentrate in the liver. Isolated cases of abnormal liver function and fulminant hepatic failure have been reported. Therapy with aminoquinolines should be administered cautiously in patients with hepatic disease or alcoholism and in patients receiving other hepatotoxic drugs. Periodic evaluation of hepatic function should be performed during prolonged therapy.
Arrhythmia
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Arrhythmia.
The use of 4-aminoquinolines such as hydroxychloroquine and chloroquine prolong the QT interval. Ventricular arrhythmias and torsades de pointes have been reported in patients taking these agents. Care should be exercised in patients with a prolonged QT interval at baseline or at increased risk for arrythmia. A baseline electrocardiogram should be obtained to assess for QT interval prolongation and other abnormalities. It is recommended to use appropriate diagnostic tools such as ECG to monitor patients during therapy.
Bone Marrow Depression/Low Blood Counts
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.
Adverse hematologic effects including neutropenia, agranulocytosis, aplastic anemia, and thrombocytopenia have been rarely associated with 4-aminoquinolines. Therapy with 4-aminoquinolines should be administered cautiously in patients with preexisting bone marrow suppression. A complete blood count should be performed periodically in patients on prolonged therapy. If any severe blood disorder appears which is not attributable to the disease under treatment, discontinuance of the drug should be considered.
Cardiomyopathy
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Cardiomyopathy.
Cardiomyopathy has been rarely reported with high daily dosages of hydroxychloroquine. Therapy with hydroxychloroquine should be monitored in patients with heart conditions. If cardiotoxicity is suspected, it is recommended to discontinue treatment with hydroxychloroquine to prevent life-threatening complications.
Cardiovascular Conditions and Disorders
Major:
ritlecitinib
Ritlecitinib has a major potential interaction with Cardiovascular Conditions and Disorders.
In a major safety study of a Janus kinase (JAK) inhibitor, tofacitinib, in rheumatoid arthritis patients 50 years and older with at least 1 cardiovascular risk factor, higher rates of all-cause mortality (including sudden cardiovascular death) and major adverse cardiovascular events (MACE) (defined as cardiovascular death, myocardial infarction, and stroke) were observed with the JAK inhibitor when compared with tumor necrosis factor (TNF) blockers. Patients who were current or past smokers had an additional increased risk. Based on a shared mechanism of action, this risk should be considered for other JAK inhibitors, including baricitinib, upadacitinib, ruxolitinib, fedratinib, ritlecitinib, deuruxolitinib, and pacritinib. Consider the benefits and risks for each individual patient prior and during treatment with JAK inhibitors, especially in patients with other cardiovascular risk factors, history of cardiovascular events, and patients who are current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and what to do if they occur.
Diabetes Mellitus
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Diabetes Mellitus.
Hydroxychloroquine has been shown to cause severe hypoglycemia including loss of consciousness that could be life threatening in patients treated with or without antidiabetic. Care should be exercised when using hydroxychloroquine in diabetic patients. Patients presenting with clinical symptoms suggestive of hypoglycemia during treatment with hydroxychloroquine should have their blood glucose checked and treatment instituted as necessary.
G-6-PD Deficiency
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with G-6-PD Deficiency.
Hemolysis and acute renal failure have been reported during use of aminoquinolines in patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. Therapy with aminoquinolines should be administered cautiously in these patients. Blood cell counts and hemoglobin determinations should be performed regularly. Aminoquinoline therapy should be discontinued immediately if signs suggestive of hemolytic anemia occur, such as marked darkening of the urine or sudden decrease in hemoglobin concentration or erythrocytic count.
Hearing Loss
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Hearing Loss.
The use of 4-aminoquinolines has been associated rarely with ototoxicity. Nerve-type deafness, which is usually irreversible, has occurred during long-term, high-dose therapy. Deafness may not be apparent until several weeks after 4-aminoquinoline therapy. Tinnitus and reduced hearing have been reported in patients with preexisting auditory damage. Therapy with 4-aminoquinolines should be administered cautiously in such patients. If new auditory defects develop or if hearing loss becomes worse, therapy should be immediately discontinued and the patient closely monitored.
History, Tuberculosis
Major:
ritlecitinib
Ritlecitinib has a major potential interaction with History, Tuberculosis.
Avoid the use of ritlecitinib in patients with an active, serious infection. Consider the risks and benefits of treatment in patients with chronic or recurrent infection, exposed to tuberculosis (TB), with a history of serious infection or an opportunistic infection, who have resided or traveled in areas of endemic TB or mycoses, or with underlying conditions that may predispose them to infection. Patients should be screened for TB before treatment initiation. This drug should not be given to patients with active TB or untreated latent TB; anti-TB therapy should be started prior to initiating treatment. Screening for viral hepatitis should be performed in accordance with clinical guidelines before starting therapy. Treatment interruption should be considered in patients with viral reactivation (e.g., herpes zoster).
Hypoglycemia
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Hypoglycemia.
Hydroxychloroquine has been shown to cause severe hypoglycemia including loss of consciousness that could be life threatening in patients treated with or without antidiabetic. Care should be exercised when using hydroxychloroquine in diabetic patients. Patients presenting with clinical symptoms suggestive of hypoglycemia during treatment with hydroxychloroquine should have their blood glucose checked and treatment instituted as necessary.
Immunodeficiency
Major:
ritlecitinib
Ritlecitinib has a major potential interaction with Immunodeficiency.
Avoid the use of ritlecitinib in patients with an active, serious infection. Consider the risks and benefits of treatment in patients with chronic or recurrent infection, exposed to tuberculosis (TB), with a history of serious infection or an opportunistic infection, who have resided or traveled in areas of endemic TB or mycoses, or with underlying conditions that may predispose them to infection. Patients should be screened for TB before treatment initiation. This drug should not be given to patients with active TB or untreated latent TB; anti-TB therapy should be started prior to initiating treatment. Screening for viral hepatitis should be performed in accordance with clinical guidelines before starting therapy.

Consider the risks and benefits of treatment in patients with chronic or recurrent infection, exposed to tuberculosis (TB), with a history of serious infection or an opportunistic infection, who have resided or traveled in areas of endemic TB or mycoses, or with underlying conditions that may predispose them to infection. Patients should be screened for TB before treatment initiation. This drug should not be given to patients with active TB or untreated latent TB; anti-TB therapy should be started prior to initiating treatment. Screening for viral hepatitis should be performed in accordance with clinical guidelines before starting therapy. Treatment interruption should be considered in patients with viral reactivation (e.g., herpes zoster).
Liver Disease
Moderate:
ritlecitinib
Ritlecitinib has a moderate potential interaction with Liver Disease.
Ritlecitinib is not recommended in patients with severe (Child Pugh C) hepatic impairment.
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Liver Disease.
Aminoquinolines may concentrate in the liver. Isolated cases of abnormal liver function and fulminant hepatic failure have been reported. Therapy with aminoquinolines should be administered cautiously in patients with hepatic disease or alcoholism and in patients receiving other hepatotoxic drugs. Periodic evaluation of hepatic function should be performed during prolonged therapy.
Myasthenia Gravis
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Myasthenia Gravis.
Certain aminoquinolines such as chloroquine, and hydroxychloroquine should be used with caution in patients with myasthenia gravis (MG). These agents may exacerbate or trigger new onset of symptoms in patients with previously diagnosed MG. It is recommended to advise patients with MG about this possible side effect.
Porphyria
Major:
Sovuna
The hydroxychloroquine in Sovuna has a major potential interaction with Porphyria.
The use of aminoquinolines in patients with porphyria may exacerbate the condition. Aminoquinolines should not be used in these patients unless the potential benefits are anticipated to outweigh the risks.
Psoriasis
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Psoriasis.
The use of aminoquinolines in patients with psoriasis may precipitate a severe attack of psoriasis. Aminoquinolines should not be used in these patients unless the potential benefits are anticipated to outweigh the risks.
Renal Dysfunction
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Renal Dysfunction.
Hydroxychloroquine is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. A dosage adjustment is not required for patients with renal impairment. Caution and monitoring should be exercised in patients with impaired renal function.
Retinal Disorders
Major:
Sovuna
The hydroxychloroquine in Sovuna has a major potential interaction with Retinal Disorders.
The use of 4-aminoquinolines is generally considered contraindicated in the presence of retinal or visual field changes, whether attributable to 4-aminoquinoline compounds or to any other etiology. However, in the treatment of acute attacks of malaria caused by susceptible strains of plasmodia, these agents may be considered if potential benefits are anticipated to outweigh the risks. 4-aminoquinolines are oculotoxic and can cause dose-related, irreversible retinal damage and vision loss during and up to several years after long-term or high-dose therapy (e.g., in the treatment of systemic lupus erythematosus or rheumatoid arthritis). Ophthalmologic monitoring, including visual acuity, expert slit-lamp, funduscopic, and visual field tests, is recommended at baseline and every three months during prolonged use. Therapy should be discontinued immediately if abnormalities develop in visual acuity, visual field, or retinal macular areas (e.g., pigmentary changes, loss of foveal reflex), or if the patient experiences visual symptoms such as light flashes and streaks that are not fully explainable by difficulties of accommodation or corneal opacities. Other common symptoms that may indicate retinopathy include nyctalopia, photophobia, blurred distance vision, difficulty reading or seeing (e.g., words or letters disappearing or parts of objects missing; misty vision; fog before the eyes), and missing or blacked out areas in the central or peripheral visual field. Retinal changes and visual disturbances may progress even after cessation of therapy. However, in a number of patients, early retinopathy (macular pigmentation sometimes with central field defects) diminished or regressed completely after therapy was discontinued. Paracentral scotoma to red targets, sometimes termed premaculopathy, is indicative of early retinal dysfunction and is usually reversible with cessation of therapy.
Seizures
Moderate:
Sovuna
The hydroxychloroquine in Sovuna has a moderate potential interaction with Seizures.
4-aminoquinolines may cause epileptic seizures in susceptible individuals. Patients with epilepsy or an otherwise low seizure threshold may be at greater risk. Therapy with 4-aminoquinolines, particularly chloroquine, should be administered cautiously in patients with epilepsy.
Smoking
Major:
ritlecitinib
Ritlecitinib has a major potential interaction with Smoking.
In a major safety study of a Janus kinase (JAK) inhibitor, tofacitinib, in rheumatoid arthritis patients 50 years and older with at least 1 cardiovascular risk factor, higher rates of all-cause mortality (including sudden cardiovascular death) and major adverse cardiovascular events (MACE) (defined as cardiovascular death, myocardial infarction, and stroke) were observed with the JAK inhibitor when compared with tumor necrosis factor (TNF) blockers. Patients who were current or past smokers had an additional increased risk. Based on a shared mechanism of action, this risk should be considered for other JAK inhibitors, including baricitinib, upadacitinib, ruxolitinib, fedratinib, ritlecitinib, deuruxolitinib, and pacritinib. Consider the benefits and risks for each individual patient prior and during treatment with JAK inhibitors, especially in patients with other cardiovascular risk factors, history of cardiovascular events, and patients who are current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and what to do if they occur.
