Belbuca is taken as a buccal film, and should be left to sit in the cheek area in order to be absorbed. The use of the film is as follows:
- Properly wash hands before touching the drug.
- Open the package containing the buccal film. Do not cut or split the film.
- Position the film in your cheek against the back of your cheek. It must be positioned in a dry part of your mouth. The film will dissolve by itself over time.
- Do not swallow, chew, or cut the film because this can impact how the drug acts.
- Do not take anything to eat or drink at least 30 minutes after inserting the film so that the film dissolves and the drug gets absorbed correctly.
Anturol works by targeting the bladder’s smooth muscle. It blocks the action of a neurotransmitter called acetylcholine, which is responsible for sending signals that cause the bladder muscles to contract. This relaxation reduces urgency and decreases the frequency of urination, increasing bladder capacity and providing better control.
Like all medicines, Belbuca can have side effects, though they will not be experienced by everyone. Some of the common side effects are:
- Nausea and vomiting: These are common side effects, particularly when first starting the drug or when increasing the dose.
- Constipation: Opioid medications like Belbuca have the side effect of constipation, which is painful and may lead to gastrointestinal problems.
- Dizziness or lightheadedness: Some people may get dizzy, especially if they get up too quickly.
- Headache: Some Belbuca users may develop headaches.
- Dry mouth: Dry mouth is another side effect that may be experienced while using buccal films.
- Drowsiness: Others may become drowsy or sleepy too while taking Belbuca.
Severe side effects that may be experienced include:
- Respiratory depression: Though Belbuca is less likely to cause breathing difficulties compared to full opioid agonists, it also has the capability of inducing breathing difficulty, especially when consuming more than prescribed or in combination with other drugs with sedating properties.
- Addiction and withdrawal symptoms: Although the potential for addiction is lower than with other opioids, there is a potential for physical dependence and withdrawal symptoms when the medication is abruptly discontinued.
- Hypotension (low blood pressure): Belbuca, in some instances, can cause a decrease in blood pressure and may result in dizziness or fainting.
- Seek immediate medical attention if you have any severe side effects.
Belbuca may interact with other medications, with higher risk of adverse side effects. Some salient interactions include
- CNS Depressants: Belbuca should not be taken with other central nervous system depressants (such as benzodiazepines, alcohol, or sedatives) because it can cause excessive sedation, respiratory depression, or even overdose.
- Other Opioids: Belbuca should not be used with other opioid drugs because it can enhance the risk of opioid toxicity and overdose.
- CYP3A4 Inhibitors: Some drugs that block the CYP3A4 enzyme (e.g., ketoconazole, ritonavir, or clarithromycin) can raise the level of Belbuca in the blood and enhance side effects.
- Tell your doctor about other medications you are taking, including over-the-counter medications, supplements, or herbal remedies, so that drug interactions can be avoided.
Belbuca dosing is titrated individually based on the intensity of the pain and the patient’s prior response to opioid drugs. The initial dose is usually 300 mcg daily. The dose can be changed based on efficacy and tolerance. Maximum doses are usually no greater than 900 mcg daily. However, your doctor will decide on the best dosage for you considering your medical condition and history.
Belbuca is a Schedule III controlled drug since it has significant potential for abuse and dependence. It can be acquired only through a doctor’s prescription. Always adhere to all prescription refill instructions and under no circumstances share the drug with another person.
