This section covers information about the recommended dosage of Piqray.
Piqray comes as an oral tablet.
Piqray is available in three strengths:
- 50 milligrams (mg)
- 150 mg
- 200 mg
The following information describes the dosing schedule that’s commonly used or recommended for Piqray. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.
For treating breast cancer, the usual starting dosage of Piqray is 300 mg once daily with food. For this dose, you’ll take two 150-mg tablets.
During your Piqray treatment, your doctor will monitor you for any side effects. Make sure to tell your doctor about any possible side effects you have during treatment. Your doctor may also prescribe other treatments to help manage certain side effects. (For more information about side effects, see this article.)
However, if you can’t tolerate certain side effects, your doctor will likely recommend dose adjustments. This includes lowering your dosage to 250 mg once daily and then to 200 mg once daily, if needed. Depending on the type or severity of side effects or how long they last, your doctor may pause or stop your treatment.
It’s important to note you should not change your dose or stop taking Piqray unless your doctor recommends you to do so.
Piqray is meant to be a long-term treatment. If you and your doctor determine that Piqray is safe and effective for you, you’ll likely take it long term.
Piqray is meant to be taken at the same time each day. If you miss a dose, what to do next depends on how many hours ago you were supposed to take the dose.
- If you miss a dose by 9 hours or less, take the missed dose as soon as possible.
- If you miss a dose by more than 9 hours, skip that day’s dose. Then, take your usual dose the next day at your regular time.
You should not take a double dose of Piqray to make up for a missed dose.
To help make sure you don’t miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.
Piqray comes as an oral tablet that you’ll swallow whole. You should not crush, cut, chew, or split the tablets. And you should not swallow Piqray tablets that look cracked, broken, or damaged. This is to ensure you’re getting the right amount of medication at the right time.
You’ll take your dose of Piqray once daily with food. There isn’t a best time of day to take Piqray. However, you should take it at about the same time each day.
It’s important that you do not take more Piqray than your doctor advises. If you take more Piqray than your doctor prescribes, you may develop serious side effects.
