Administration Instructions for Ruxolitinib

Ruxolitinib is taken orally and can be administered with or without food. To maintain consistent levels of the medication in your body, take it at the same time each day. If you miss a dose, take it as soon as you remember. However, if it is close to the time of your next scheduled dose, skip the missed dose and resume your regular schedule.

Contraindications for Ruxolitinib Treatment

A contraindication refers to a condition or circumstance in which a medication should not be used because it may pose significant risks. For individuals considering Ruxolitinib treatment, certain health conditions can make this medication unsafe. Below are the primary contraindications associated with Ruxolitinib:

Severe Liver Impairment: Ruxolitinib is processed by the liver. If liver function is severely compromised, the drug may accumulate in the body, increasing the likelihood of toxicity and adverse effects.

Severe Kidney Impairment: The kidneys play a critical role in eliminating Ruxolitinib from the body. When kidney function is significantly impaired, the drug may build up in the bloodstream, raising the risk of harmful side effects.

Active, Serious Infections: As a JAK inhibitor, Ruxolitinib suppresses the immune system, which can make it more difficult for the body to fight infections. If you have a serious or ongoing infection, this medication could potentially worsen your condition.

Low Blood Cell Counts: Ruxolitinib can reduce levels of red blood cells, white blood cells, and platelets. If you already have low blood cell counts, taking this medication may increase the risk of complications such as anemia, infections, or bleeding.

If you have any of these conditions, it is essential to discuss them with your healthcare provider before starting Ruxolitinib treatment. Our telemedicine providers are available to review your medical history and help determine whether Ruxolitinib is a safe and appropriate option for you.

Drug-to-Drug Interactions with Ruxolitinib

Ruxolitinib can interact with other medications, potentially leading to side effects or reducing the effectiveness of your treatment. Below are some common medications that may interact with Ruxolitinib:

1. Ketoconazole (Nizoral): This antifungal medication can increase Ruxolitinib levels in the bloodstream, heightening the risk of side effects.
2. Fluconazole (Diflucan): Another antifungal that may elevate Ruxolitinib levels, potentially leading to toxicity.
3. Rifampin (Rifadin): This antibiotic can decrease Ruxolitinib concentrations, which may reduce its effectiveness.
4. Clarithromycin (Biaxin): This antibiotic may raise Ruxolitinib levels in the body, increasing the likelihood of adverse effects.
5. Warfarin (Coumadin): When combined with blood thinners like Warfarin, Ruxolitinib may elevate the risk of bleeding complications.

It is crucial to inform your healthcare provider about all medications you are currently taking, including over-the-counter drugs, herbal supplements, and vitamins. If you have concerns about potential interactions, our telemedicine team can review your medication list and adjust your treatment plan to ensure your safety.
