Siklos 174;, the first and only hydroxyurea-based treatment for pediatric patients with sickle cell anemia, now available in 100 mg scored tablets to help further optimize dosing

ROSEMONT, Pa., Oct. 19, 2020 /PRNewswire/ - Medunik USA is proud to announce that Siklos® (hydroxyurea), indicated to reduce the frequency of painful crises and to reduce the need for blood transfusions in children, 2 years of age and older, with sickle cell anemia with recurrent moderate to severe painful crises¹, is now available in a 100 mg scored tablet in addition to the 1,000 mg triple-scored tablets.

Siklos® has a Boxed Warning regarding low blood cell counts and cancer; please read Important Safety Information below.

“Medunik USA is proud to offer pediatric SCA patients a new option that helps optimize daily dosing. With the newly available Siklos® 100 mg scored tablets, dose adjustments can now be made in 50 mg increments. Coupled with Siklos® 1,000 mg triple-scored tablets (4 x 250 mg), this will offer more accurate dose adjustments and may make it more convenient than compounded hydroxyurea,” affirmed Tanya Carro, General Manager, at Medunik USA.

The importance of optimal dosing of hydroxyurea in sickle cell anemia (SCA) patients, based on patient body weight and biological and clinical response, has been well established.^2,3 This is particularly relevant in pediatric populations, where patient weight is constantly changing.

In addition to its flexible dosing, Siklos® may help increase patient compliance, as it is dissolvable in water for patients who are unable to swallow tablets whole.⁴ Siklos® tablets should be taken once daily, at the same time every day, with a glass of water. For patients who are not able to swallow the tablets, they can be dispersed immediately before use in a small quantity of water in a teaspoon.

“I can’t stress enough the importance of treating pediatric patients as early as possible. Why wait for painful episodes to occur and risk complications when you can give a child Siklos® and reduce the frequency of recurrent painful crises once they turn 2? There’s no reason to wait. Physicians and parents need to know about Siklos®!,” said Dr. Corey Hebert, MD, Chief Medical Officer at Dillard University and well-known medical broadcast journalist.

Medunik is committed to providing Siklos® at the lowest possible cost to all patients. That is why the company continues to offer cost savings and free home delivery through the Siklos At Home™ program.

Your healthcare provider will check your blood cell counts before and every 2 weeks during treatment with SIKLOS. Your healthcare provider may change your dose or tell you to stop taking SIKLOS if you have low blood cell counts. Tell your healthcare provider right away if you get any of the following symptoms: fever or chills; shortness of breath; body aches; unusual headache; feeling very tired; bleeding or unexplained bruising.
