Uses for trilaciclib

Trilaciclib injection is used to help reduce myelosuppression (bone marrow problem) caused by certain cancer medicines (eg, platinum/etoposide, topotecan) to treat patients with extensive-stage small cell lung cancer (ES-SCLC).

Trilaciclib is to be given only by or under the direct supervision of your doctor.

Before using trilaciclib

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For trilaciclib, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to trilaciclib or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of trilaciclib injection in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of trilaciclib injection in the elderly.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving trilaciclib, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using trilaciclib with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

  • Cisplatin
  • Dalfampridine
  • Dofetilide

Interactions with food/tobacco/alcohol

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Other medical problems

The presence of other medical problems may affect the use of trilaciclib. Make sure you tell your doctor if you have any other medical problems, especially:

  • Liver disease, moderate or severe—Use is not recommended in patients with this condition.
  • Lung problems—Use with caution. May make this condition worse.

Proper use of trilaciclib

A nurse or other trained health professional will give you trilaciclib in a medical facility. It is given through a needle placed into one of your veins. Trilaciclib must be given slowly, so the needle will have to remain in place for at least 30 minutes. It is given within 4 hours before you receive your cancer treatment.

Missed dose

Call your doctor or pharmacist for instructions.

Precautions while using trilaciclib

It is very important that your doctor check your progress closely and at regular visits to make sure that trilaciclib is working properly. Blood tests may be needed to check for unwanted effects.

Receiving trilaciclib while you are pregnant can harm your unborn baby. If you are a woman who can get pregnant, your doctor may do tests to make sure you are not pregnant before starting treatment. Use an effective form of birth control to keep from getting pregnant during treatment and for at least 3 weeks after the last dose. If you think you have become pregnant while receiving the medicine, tell your doctor right away.

Trilaciclib may cause serious injection-site reactions (eg, phlebitis, thrombophlebitis). Check with your doctor right away if you have bluish color, changes in skin color, or pain, tenderness, or swelling at the injection site.

Trilaciclib may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Check with your doctor right away if you have a rash, itching, hives or welts, redness of the skin, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, mouth, or tongue while you are using trilaciclib.

Trilaciclib may cause lung or breathing problems (eg, interstitial lung disease, pneumonitis), which can be life-threatening. Check with your doctor right away if you have chest pain, chills, cough, fever, general feeling of discomfort or illness, thickening of bronchial secretions, or trouble breathing.

Talk with your doctor before using trilaciclib if you plan to have children. Some women who use trilaciclib have become infertile (unable to have children).

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
