Usage:
Selumetinib is administered in capsule form and should be taken orally. Here are the recommended steps:
• Take selumetinib twice daily, ideally on an empty stomach. Ensure there's a 2-hour gap before and a 1-hour gap after each dose without food. Try to maintain approximately 12-hour intervals between doses.
• Follow your prescription label's instructions meticulously, and don't hesitate to seek clarification from your doctor or pharmacist if any details are unclear. It's crucial to adhere to the prescribed regimen—neither exceed nor reduce the dose and avoid taking it more frequently than directed.
• Swallow the capsules whole with water, refraining from opening, chewing, or crushing them.

| Storage |
Storage:
Store this medication in its original container, securely closed, and away from children. Keep it at room temperature, avoiding excess heat and moisture (do not store it in the bathroom). Retain the desiccant (small moisture-absorbing packet) in the bottle.
Protect children from potential harm by keeping all medications out of their sight and reach. Many containers, including those for eye drops, creams, patches, and inhalers, are not child-resistant and can be easily opened by young children. To prevent accidental poisoning, always secure safety caps and promptly store medications in a safe location that is inaccessible to children.
Dispose of any unused medications properly to prevent accidental consumption by pets, children, or others. Do not flush this medication down the toilet. Instead, utilize a medicine take-back program. Consult your pharmacist or contact your local garbage/recycling department to inquire about available take-back programs in your community.

| Special Precautions |
Special Precautions:
Before starting selumetinib treatment, it's essential to communicate the following information to your doctor and pharmacist:
• Any known allergies to selumetinib, other medications, or any components in selumetinib capsules. Request a list of ingredients from your pharmacist if needed.
• A comprehensive list of all prescription and nonprescription medications, vitamins, supplements, and herbal products you are taking or intend to take. Highlight medications like blood thinners, antifungals, corticosteroids, HIV medications, and others, as they may interact with selumetinib. Your doctor may need to adjust dosages or monitor you for potential side effects.
• Mention any herbal products you use, especially St. John's wort.
• Provide your medical history, including any vision problems, difficulty swallowing, or heart/liver conditions.
• If you are pregnant, planning pregnancy, or considering fathering a child, your doctor needs to know. Female patients should undergo a pregnancy test before beginning treatment and use contraception throughout the treatment period and for at least one week after the final dose. Male patients and their partners should also use birth control during treatment and for one week following the last dose. If pregnancy occurs during selumetinib treatment, contact your doctor immediately, as selumetinib may pose risks to the fetus.
• If you are breastfeeding, refrain from doing so while taking selumetinib and for one week after completing treatment.
Open and honest communication with your healthcare provider is essential for your safety and effective treatment. Your doctor will use this information to ensure your well-being and provide the best possible care.
