Tukysa ^*

HER2-positive breast cancer is a type where cancer cells have excess levels of a protein called HER2, which promotes cell growth. Tukysa is a targeted therapy designed to block this specific protein. This type of cancer can be more aggressive than others. Your doctor performs a test on the tumor tissue to determine if the cancer is HER2-positive before prescribing this medication, as it is only effective for this subtype.

Tukysa is taken as a pill twice daily, while trastuzumab is given as an infusion and capecitabine is another oral pill. Your oncologist will provide a precise schedule for all three medications. It is critical to follow this schedule carefully to ensure the combination therapy is as effective as possible. Do not change the doses or schedule without consulting your doctor.

Diarrhea is a very common side effect of Tukysa and can be serious. You should contact your doctor at the first sign of diarrhea. They will likely recommend starting anti-diarrheal medication, like loperamide, and increasing your fluid intake to prevent dehydration. Do not wait for it to become severe before seeking medical advice, as it can lead to serious complications if unmanaged.

Tukysa can be taken with or without a meal, according to your preference. Taking it at the same time each day, about 12 hours apart, is the most important factor for maintaining a consistent level of the drug in your body. If you take it with food and experience nausea, try taking it on an empty stomach, or vice-versa, after consulting your pharmacist.

If you miss a dose of Tukysa, you should take it as soon as you remember, as long as it is more than 6 hours until your next scheduled dose. If it is less than 6 hours away, you should skip the missed dose completely and just take your next dose at the regular time. Do not take two doses at once to make up for a missed one.

Yes, while taking Tukysa your doctor will need to monitor you closely. This includes performing regular blood tests to check your liver function, as Tukysa can cause liver inflammation or damage. These tests help your doctor catch any potential problems early and adjust your treatment if necessary to keep you safe. Your overall health and blood counts will also be monitored.

Tukysa should be stored in its original container at room temperature, between 68°F to 77°F (20°C to 25°C). Keep the bottle tightly closed and in a dry place. It is important to keep this medication away from moisture, heat, and direct sunlight. As with all prescription drugs, keep it securely out of the reach of children and pets.

Tukysa is considered a targeted therapy, not a traditional chemotherapy. While it is used with the chemotherapy drug capecitabine, Tukysa itself works by specifically targeting the HER2 protein on cancer cells. This is different from traditional chemotherapy, which generally affects all rapidly dividing cells in the body, both cancerous and healthy. This targeted action can lead to different side effects.

Tukysa tablets must be swallowed whole. You should not crush, split, chew, or dissolve the tablets. Breaking the tablet can alter how the medication is absorbed by your body, which could change its effectiveness and potentially increase side effects. If you have trouble swallowing pills, you should discuss this with your doctor or pharmacist before starting treatment for possible solutions.

Tukysa itself is not strongly associated with significant hair loss (alopecia). However, it is used in a combination regimen that includes capecitabine, which can cause hair thinning or mild hair loss in some patients. The hair loss experienced is typically much less severe than with many traditional intravenous chemotherapy regimens. Discuss any concerns you have about this with your healthcare provider.

You will typically continue to take Tukysa for as long as it is effectively controlling your cancer and you are not experiencing unmanageable side effects. The duration of your treatment is a decision that you and your oncologist will make together based on your response to the therapy and regular evaluations. Do not stop taking Tukysa without your doctor's instruction.

You should discuss alcohol consumption with your doctor before taking Tukysa. Both alcohol and Tukysa can affect the liver. Combining them could potentially increase the risk of liver-related side effects. Your doctor can provide personalized advice based on your overall health, liver function, and other medications you are taking. It is often recommended to limit or avoid alcohol during cancer treatment.
