Genetic testing

  • Uncovering Periodic Paralysis is a no-cost gene panel testing program for patients who may have PPP as well as their eligible first-degree family members
  • The Periodic Paralysis Panel includes analysis for both hyperkalemic and hypokalemic periodic paralysis, testing for the three most common associated genes: SCN4A, CACNA1S, KCNJ2, and RYR1
  • Visit to order a genetic test or request a specimen collection kit

Access assistance

*Eligible patients pay as little as $0 with a maximum annual savings of $10,000. The authorized specialty pharmacy will activate the copay card for eligible patients and apply for each prescription until the annual maximum has been reached. This card is not valid for prescriptions that may be reimbursed under a federal or state healthcare program, including Medicare, Medicaid, or any other similar federal or state healthcare program, including any state pharmacy assistance program. For additional questions about the co-pay program, including eligibility, call Strongbridge CareConnection at 844-KEVEYIS (538‑3947)



KEVEYIS is indicated for the treatment of primary hyperkalemic periodic paralysis, primary hypokalemic periodic paralysis, and related variants.

Important Safety Information

  • Hypersensitivity to dichlorphenamide or other sulfonamides
  • Concomitant use of KEVEYIS and high-dose aspirin
  • Severe pulmonary disease, limiting compensation to metabolic acidosis caused by KEVEYIS
  • Hepatic insufficiency: KEVEYIS may aggravate hepatic encephalopathy
Warnings and Precautions

Hypersensitivity and Other Life-Threatening Reactions

  • Fatalities associated with the administration of sulfonamides have occurred because of adverse reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anemia, and other blood dyscrasias.
  • Pulmonary involvement can occur in isolation or as part of a systemic reaction.
  • Discontinue KEVEYIS at the first appearance of skin rash or any sign of immune-mediated or other life-threatening adverse reaction.

Concomitant Use of Aspirin or Other Salicylates

  • Carbonic anhydrous inhibitors, including KEVEYIS, can cause metabolic acidosis, which can increase the risk of salicylate toxicity.
  • Anorexia, tachypnea, lethargy, and coma have been reported with concomitant use of dichlorphenamide and high-dose aspirin.
  • Concomitant use of KEVEYIS and high-dose aspirin is contraindicated. Use with caution and carefully monitor in patients receiving low-dose aspirin.


  • KEVEYIS increases potassium excretion and can cause hypokalemia.
  • The risk of hypokalemia is greater when KEVEYIS is used in patients with conditions associated with hypokalemia (e.g., adrenocortical excess, renal tubular acidosis type 1 and 2), and in patients receiving other drugs that may cause hypokalemia (e.g., loop diuretics, thiazide diuretics, laxatives, antifungals, penicillin, and theophylline).
  • Baseline and periodic measurements of serum potassium are recommended.
  • If hypokalemia develops or persists, consider reducing the dose or discontinuing KEVEYIS and correction of potassium levels.

Metabolic Acidosis

  • KEVEYIS can cause hyperchloremic non-anion gap metabolic acidosis.
  • Concomitant use of KEVEYIS with other drugs that cause metabolic acidosis may increase the severity of acidosis.
  • Concomitant use of KEVEYIS in compensated patients with respiratory acidosis, such as in advanced lung diseases, may lead to respiratory decompensation.
  • Baseline and periodic measurements of serum bicarbonate during KEVEYIS treatment are recommended.
  • If metabolic acidosis develops or persists, consider reducing the dose or discontinuing KEVEYIS.


  • KEVEYIS increases the risk of falls; risk is greater in the elderly and with higher doses.
  • Consider dose reduction or discontinuation of KEVEYIS in patients who experience falls while treated with KEVEYIS.
Pregnancy and Lactation

Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known in humans whether dichlorphenamide is excreted in human milk; exercise caution when administered to a nursing woman.

Adverse Reactions

The most common adverse reactions seen in clinical trials (incidence ≥ 10% and greater than placebo) include paresthesias, cognitive disorder, dysgeusia, and confusional state.
