Fire Brand Chemicals – Fentanyl Hcl – Medical uses.
Why is Fentanyl Hcl prescribed?
Fentanyl Hcl is used to treat breakthrough pain (sudden episodes of pain that occur despite round the clock treatment with pain medication) in cancer patients at least 18 years of age (or at least 16 years of age if using Actiq brand lozenges).
Who are taking regularly scheduled doses of another narcotic (opiate) pain medication, and who are tolerant (used to the effects of the medication) to narcotic pain medications. Fentanyl is in a class of medications called narcotic (opiate) analgesics.
It works by changing the way the brain and nervous system respond to pain.
How should Fentanyl Hcl be used?
Fentanyl comes as a lozenge on a handle (Actiq), a sublingual (underneath the tongue) tablet (Abstral), a film (Onsolis), and a buccal (between the gum and cheek) tablet (Fentora) to dissolve in the mouth.
Fentanyl is used as needed to treat breakthrough pain but not more often than four times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
Your doctor will probably start you on a low dose of fentanyl and gradually increase your dose until you find the dose that will relieve your breakthrough pain.
If you still have pain 30 minutes after using fentanyl films (Onsolis), your doctor may tell you to use another pain medication to relieve that pain, and may increase your dose of fentanyl films (Onsolis) to treat your next episode of pain .
Talk to your doctor about how well the medication is working and whether you are experiencing any side effects so that your doctor can decide whether your dose should be adjusted.
Do not use fentanyl more than four times a day. Call your doctor if you experience more than four episodes of breakthrough pain per day.
Your doctor may need to adjust the dose of your other pain medication(s) to better control your pain.
Swallow the buccal tablet whole; do not split, chew, or crush. Also do not chew or bite the lozenge on a handle; only suck on this medication as directed.
Do not stop using fentanyl without talking to your doctor. Your doctor may decrease your dose gradually. If you suddenly stop using fentanyl, you may experience unpleasant withdrawal symptoms.
To use Fentanyl Hcl lozenges (Actiq), follow these steps:
- Check the blister package and the handle of the lozenge to make sure the lozenge contains the dose of medication you have been prescribed.
- Use scissors to cut open the blister package and remove the lozenge. Do not open the blister package until you are ready to use the medication.
- Place the lozenge in your mouth, between your cheek and gum. Actively suck on the lozenge, but do not chew, crush, or bite it. Move the lozenge around in your mouth, from one side to the other, using the handle. Twirl the handle often.
- Do not eat or drink anything while the lozenge is in your mouth.
- Finish the lozenge in about 15 minutes.
- If you begin to feel dizzy, very sleepy, or nauseated before you have finished the lozenge, remove it from your mouth. Dispose of it immediately as described below or put it in the temporary storage bottle for later disposal.
- If you finish the entire lozenge, throw the handle away in a garbage can that is out of the reach of children. If you did not finish the entire lozenge, hold the handle under hot running water to dissolve all the medication, and then throw the handle away in a garbage can that is out of the reach of children and pets.
To use Fentanyl Hcl buccal tablets (Fentora), follow these steps:
- Separate one blister unit from the blister card by tearing along the perforations. Peel back the foil to open the blister unit. Do not try to push the tablet through the foil. Do not open the blister unit until you are ready to use the tablet.
- Place the tablet in your mouth above one of your upper back teeth between your cheek and your gum.
- Leave the tablet in place until it dissolves completely. You may notice a gentle bubbling feeling between your cheek and gum as the tablet dissolves. It may take 14 to 25 minutes for the tablet to dissolve. Do not split, chew, bite, or suck the tablet.
- If any of the tablet is left in your mouth after 30 minutes, swallow it with a drink of water.
- If you begin to feel dizzy, very sleepy, or nauseated before the tablet dissolves, rinse your mouth with water and spit the remaining pieces of tablet into the sink or toilet. Flush the toilet or rinse the sink to wash away the tablet pieces.
1). Fentanyl Hcl Anesthesia
To maintain anesthesia, inhaled anesthetics and additional fentanyl may be used. These are often given in 15–30-minute intervals throughout procedures such as endoscopy, surgeries, and emergency rooms.
For pain relief after surgery, use can decrease the amount of inhalational anesthetic needed for emergence from anesthesia.
Balancing this medication and titrating the drug based on expected stimuli and the person’s responses can result in stable blood pressure and heart rate throughout a procedure and a faster emergence from anesthesia with minimal pain.
2). Obstetrics of Fentanyl Hcl
Because of fentanyl’s high lipid solubility, its effects are more localized than morphine, and some clinicians prefer to use morphine to get a wider spread of analgesia.
However, it is widely used in obstetrical anesthesia because of its short time to action peak (about 5 min), the rapid termination of its effect after a single dose, and the occurrence of relative cardiovascular stability.
In obstetrics, the dose must be closely regulated in order to prevent large amounts of transfer from mother to fetus. At high doses, the drug may act on the fetus to cause postnatal respiratory distress.
For this reason, shorter-acting agents such as alfentanyl or remifentanil may be more suitable in the context of inducing general anesthesia.
3). Pain management of Fentanyl Hcl
The bioavailability of intranasal fentanyl is about 70–90%, but with some imprecision due to clotted nostrils, pharyngeal swallow, and incorrect administration.
For both emergency and palliative use, intranasal fentanyl is available in doses of 50, 100, and 200 µg.
In emergency medicine, safe administration of intranasal fentanyl with a low rate of side effects and a promising pain-reducing effect was demonstrated in a prospective observational study in about 900 out-of-hospital patients.
In children, intranasal fentanyl is useful for the treatment of moderate and severe pain and is well tolerated.
Adverse effects of Fentanyl Hcl
Fentanyl HCL’s most common side effects, which affect more than 10% of people, include diarrhea, nausea, constipation, dry mouth, somnolence, confusion, asthenia (weakness), sweating. Less frequently, in 3-10% of people.
Fentanyl can cause abdominal pain, headache, fatigue, anorexia and weight loss, dizziness, nervousness, hallucinations, anxiety, depression, flu-like symptoms, dyspepsia (indigestion), shortness of breath, hypoventilation, apnoea, and urinary retention.
