Required information to disclose and storage requirements before taking alectinib
To ensure medication safety, before the first dose of alectinib, you must fully disclose the following health information to your physician and strictly follow the storage guidelines:
Personal conditions that must be disclosed to the doctor:
Liver disease history
If you have a history of hepatitis, cirrhosis, alcoholic liver disease, or abnormal liver function after prior chemotherapy, baseline liver function should be assessed in advance, and the starting dose may need adjustment.
Respiratory system diseases
If you have interstitial pneumonia, pulmonary fibrosis, or chronic obstructive pulmonary disease, the risk of pulmonary complications during treatment is increased, and enhanced imaging monitoring is required.
Cardiac conduction abnormalities
If you have a known history of bradycardia, sick sinus syndrome, atrioventricular block, or syncope, a 24‑hour Holter electrocardiogram should be performed before initiating therapy.
Pregnancy and breastfeeding status
Alectinib may cause harm to the fetus. Women of childbearing age must use highly effective contraceptive measures during treatment and for at least 3 months after the last dose. If you are pregnant or planning to become pregnant, inform your doctor immediately. Breastfeeding is contraindicated because the drug may be excreted into breast milk, and the potential risk to the infant is unknown. It is recommended to wait at least 7 days after the last dose before considering resuming breastfeeding (follow specific medical advice).
Storage precautions (critical for maintaining drug efficacy):
Temperature and container
Store in the original container; do not transfer to other containers. The ambient temperature must not exceed 30°C (86°F). Do not place in bathrooms, kitchens, or other humid and hot areas.
Moisture and light protection
Keep capsules dry. Close the cap tightly immediately after each use, and avoid direct sunlight or prolonged exposure to strong indoor light.
Child safety
All medications must be kept out of children's reach, either in a high place or a locked cabinet, to prevent accidental ingestion.
Key contraindications during alectinib treatment
Adhering to the standard dosing regimen and avoiding risky behaviors are essential for ensuring efficacy and reducing adverse reactions. Please strictly observe the following details:
Administration method (to be followed daily):
Dose and frequency
Take strictly according to the prescribed dose, usually twice daily (morning and evening), with an interval of approximately 12 hours between doses. Do not increase, decrease, or discontinue the dose on your own; any adjustment must be evaluated by the attending physician.
Meal requirements
Each dose must be taken with food (e.g., during breakfast or dinner). Taking with food improves drug absorption and reduces gastrointestinal irritation. Avoid taking on an empty stomach.
Swallow whole
Capsules must be swallowed whole without chewing, crushing, opening, or dissolving the contents. If you have difficulty swallowing, consult your doctor about alternative dosage forms, but do not change the form on your own.
Missed dose management
If you forget to take a dose and it is more than 6 hours before the next scheduled dose, you may take the missed dose. If it is less than 6 hours to the next dose, skip the missed dose and take the next one as scheduled. Never double up to make up for the missed dose.
Management after vomiting
If vomiting occurs immediately (within 15‑30 minutes) after taking the dose, it is usually not recommended to retake the dose; just take the next dose at the regular time. If vomiting occurs more than 1 hour after administration, the drug has been largely absorbed and no additional action is required.
Behaviors that must be avoided (throughout treatment and for 7 days after the last dose):
Strict photoprotection
This drug is photosensitive. Exposure to sunlight or UV light can easily cause severe sunburn, blistering, or hyperpigmentation. When going outdoors, apply a broad‑spectrum sunscreen with SPF ≥50 to all exposed skin (including face, neck, and back of hands), and use a lip balm with sun protection. Wear long‑sleeved clothing, a wide‑brimmed hat, and sunglasses.
Other restrictions
Avoid concomitant use of drugs known to prolong the QT interval or slow heart rate (e.g., amiodarone, clarithromycin). If co‑administration is unavoidable, enhanced electrocardiographic monitoring is required. In addition, alcohol consumption is prohibited during treatment to avoid increasing liver burden.
