Zubsolv

Zubsolv is a prescription medication used to treat adults who are addicted to opioid drugs (either prescription or illegal) as part of a complete treatment program that also includes counseling and behavioral therapy.

Zubsolv comes in tablets to be dissolved under the tongue, once daily. Do not cut, chew, or swallow Zubsolv tablets. 

Common side effects include headache, drug withdrawal syndrome, nausea, and decrease in sleep.

Zubsolv can also cause blurred vision, drowsiness, and dizziness. Do not drive or operate heavy machinery until you know how Zubsolv affects you.

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Zubsolv falls into category C. There are no well-controlled studies that have been done in pregnant women. Zubsolv should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.

Tell your doctor if you are breastfeeding or plan to breastfeed.

Buprenorphine has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from Zubsolv, a choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.

Take Zubsolv exactly as prescribed.

Zubsolv is available as a tablet that is applied sublingually (under the tongue). Avoid eating or drinking until the tablet has dissolved entirely. The various forms of buprenorphine and naloxone medication are not interchangeable.

If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of Zubsolv at the same time.

Take this medication exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

The dose your doctor recommends may be based on the following:

• the condition being treated
• how you respond to this medication

The dose of Zubsolv (buprenorphine and naloxone) should be increased slowly until reaching a level that maintains the patient’s treatment and suppresses signs and symptoms of opioid withdrawl.

If you take too much Zubsolv, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

If Zubsolv is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.

• Store Zubsolv at 20-25°C (68-77°F).
• Keep this and all medicines out of the reach of children.
