Others follow normal procedures and use legal medications like painkillers and pain relievers.

So today, Healthsoothe will be focusing on a pain reliever known as WES 303.

WES 303 is among many of the pain relievers out there that people use to alleviate or relieve their physical pains.

So if you are having pains due to arthritis or pains from a post-dental surgery and you are thinking about using WES 303 and you are wondering how safe this drug is, how it works, its benefits, side effects, and other things.

Then don’t worry, we got you covered here. This article will answer all these questions and more.

WES 303 – What is it?

It is a pain-relieving drug that is formed from the combination of two other medicines - Acetaminophen and Hydrocodone Bitartrate. It belongs to the drug class of narcotic analgesic combinations.

Narcotic analgesic combinations are products that contain a narcotic analgesic in combination with at least one other analgesic; for example, hydrocodone and acetaminophen, oxycodone, and acetaminophen.

Narcotic analgesic combinations should only be used to treat moderate-to-severe pain that is not responsive to other less potent analgesics. An analgesic is a name used to describe a medicine that relieves pain.

How does WES 303 work?

The active constituents or ingredients of WES 303 are the core function of the drug. These are Acetaminophen and Hydrocodone Bitartrate;

• Acetaminophen (fever reducer and pain reliever): This non-narcotic analgesic works by raising the threshold to pain; that is, higher stimulation of the neurons responsible for pain sensation is required for the pain to be sensed. It decreases fever by acting on the brain's temperature-regulating region.
• Hydrocodone Bitartrate (pain reliever and cough suppressant): This narcotic acts by inhibiting the receptors and synapses on nerve tissue and cells in the brain that cause pain sensations. It is comparable to codeine.

To relieve pain, hydrocodone and acetaminophen are often mixed. Together, they form the combination medicine – WES 303 is used to relieve moderate to severe pain.

How should I use WES 303?

It is administered orally, with or without meals.

If you're going to use an oral solution, be sure you complete the following:

• Use calibrated measuring equipment to determine the dosage.
• Before administration, double-check the dosage in milliliters and milligrams.

Please follow all of the instructions on your prescription label. Never use this medication in bigger doses or for a longer period than suggested.

An overdose might harm your liver or perhaps kill you. Inform your doctor if you have an increased desire to take this medication.

Never give this medication to anybody else, particularly someone who has a history of drug misuse or addiction. Misuse may lead to addiction, overdose, and death.

Keep the medication in a location where others cannot get it. It is illegal to sell or distribute WES 303 tablets.

Patients should be thoroughly monitored for respiratory depression during the first 24 to 72 hours after starting medication and after each dosage increase.

This is for the treatment of pain that is severe enough to need the use of an opioid analgesic which renders alternate therapies ineffective.

Adjustments of dose

In elderly or debilitated individuals, as well as those with prostatic hypertrophy, hypothyroidism, urethral stricture, or Addison's disease, acetaminophen-hydrocodone should be taken with caution; typically, begin at the lower end of the dose range and titrate cautiously.

See the following adjustments;

• Adjustments for liver dose: Caution is advised for persons with hepatic or liver issues who may have greater plasma concentrations of hydrocodone, and they should be continuously monitored for adverse effects.
• Kidney dose adjustments: Caution is advised for persons with renal or kidney issues who may have greater plasma concentrations of hydrocodone, and they should be continuously monitored for adverse effects.

The maximum acetaminophen dosage in 24 hours is 4g. When determining the daily dosage, include all acetaminophen products. To prevent an acetaminophen overdose, use just one product of acetaminophen at a time.

• Conversion due to other opioids: Due to substantial inter-patient variability in reaction to the strength of opioid medicines and formulations, a cautious approach is suggested; it is better to underestimate than overestimate and treat an unpleasant reaction due to overdose.
• The use of CYP450 3A4 inhibitors or inducers concurrently may need dosage modification (Check drug interactions section).

Therapy discontinuation in the addicted person or patient

• Gradually reduce or taper the dosage by 25-50% every 2-4 days.
• Monitor for withdrawal symptoms; if they occur, increase the dosage to the prior level and reduce or taper even more slowly.
• Do not suddenly stop treatment for the addict.

What if I miss significant doses of WES 303?

Nothing much will happen. Just that if you have missed significant doses of the drug, it will not be effective or potent enough to treat you for the ailment you took it for.

Do the following if you have missed dose on significant doses;

• If you forget to take one or more doses: take your next dose at the usual time and in the average amount. Do not take anymore than your doctor prescribed.
• If you miss one dose, skip it and continue with your normal schedule.
• Do not increase the dosage to catch up with the missed doses.
• You should consult your doctor on what to do if you don’t know what to do.

What if I overdose on WES 303?

Excessive sleepiness, extremely slow-paced breathing, coma, severe muscular weakness, and pinpoint pupils may also result from an overdose.

A WES 303 tablet overdose may be lethal. appetite loss, vomiting, nausea, stomach discomfort, sweating, and disorientation or weakness are the initial indicators of an acetaminophen overdose.

Symptoms that may come later include upper stomach discomfort, black urine, and yellow skin or whites of your eyes. Seek immediate medical treatment or call 1-800-222-1222 for Poison Help.

Uses of WES 303 pill

Its main function is being a pain reliever. It also acts as an antipyretic – fever reducer. It is used to treat moderate to severe pain.

This medicine may be used for other purposes, and you can also ask your healthcare provider or pharmacist if you have questions.

Side effects of WES 303 pill

• Common side effects include:
• Headache
• Fatigue or tiredness
• Drowsiness/Dizziness
• Nausea
• Constipation
• Vomiting
• Stomach pain

If you experience hives, trouble breathing, or swelling of your face, lips, tongue, or neck, get immediate medical attention. Opioids may cause your respiration to slow or stop, and death is possible.

If you have sluggish breathing with extended pauses, blue-colored lips, or difficulty waking up, someone caring for you should seek immediate medical treatment.

Acetaminophen may induce a severe skin response that can be deadly in rare situations. This might happen even if you have previously taken acetaminophen without experiencing any side effects.

If you have skin redness or a rash that spreads and causes blistering and peeling, stop taking this medication and contact your doctor straight once.

Call your doctor at once if you have:

• Low cortisol levels — nausea, vomiting, loss of appetite, dizziness, worsening tiredness, or weakness.
• A light-headed feeling, like you, might pass out
• Noisy breathing, sighing, shallow breathing, breathing that stops during sleep;
• Liver problems –nausea, upper stomach pain, tiredness, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes)

Seek medical attention right away if you have symptoms of serotonin syndrome, such as agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

Serious side effects may be more likely in older adults and those who are overweight, malnourished, or debilitated.

Long-term use of opioid medication may affect fertility (ability to have children) in men or women. It is not known whether opioid effects on fertility are permanent.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088 or your healthcare provider or doctor.

Warnings and precautions for taking WES 303

The following warnings and precautions are to be noted and observed;

• When used with benzodiazepines or other CNS depressants, such as alcohol, it may cause extreme drowsiness, respiratory depression, coma, and death. Concomitant usage should be reserved for individuals who have exhausted all other therapy options. Limit the dosage and duration as needed, and monitor patients for signs and symptoms of respiratory depression and drowsiness.
• Accidental Ingestion: Inadvertent ingestion, particularly by youngsters, may result in a lethal overdose.
• Serious, life-threatening, or deadly respiratory depression: Serious, life-threatening, or fatal respiratory depression may occur, particularly during or after a dosage increase.
• Addiction, abuse, and misuse: This medication puts patients and other users at risk of opioid addiction, abuse, and misuse, which may result in overdose and death. Before prescription, assess each patient's risk and frequently monitor all patients for the development of these habits or disorders.
• Hepatotoxicity: Acetaminophen has been linked to cases of acute liver failure, sometimes resulting in liver transplantation and death; most cases of liver injury are linked to acetaminophen use at doses greater than 4000 mg per day, and frequently involve more than one acetaminophen-containing product.
• Interaction with CYP450 3A4 inhibitors: Using CYP450 3A4 inhibitors concurrently may result in higher hydrocodone plasma concentrations, which may exacerbate or prolong undesirable pharmacological effects and induce possibly deadly respiratory depression. Furthermore, discontinuing a concurrently taken CYP450 3A4 inducer may result in higher hydrocodone plasma concentrations. Patients receiving any CYP450 3A4 inhibitor or inducer should be closely monitored.
• Opioid withdrawal syndrome in infants: Prolonged usage during pregnancy may cause newborn opioid withdrawal syndrome, which can be fatal if not diagnosed and treated, and necessitates therapy according to neonatology specialists' guidelines. If an opioid is needed for an extended length of time in a pregnant woman, the patient should be informed about the danger of neonatal opioid withdrawal syndrome and ensure that proper therapy is provided. To find out about the best therapy and treatment for opioid addiction and dependency, ANR Clinic will help you explore the wonders of the Accelerated Neuro-Regulation approach.
• Medication error risks: When prescribing, dispensing, and delivering hydrocodone/acetaminophen oral solution, ensure accuracy; dosage mistakes caused by a misunderstanding between mg and ml, as well as other hydrocodone/acetaminophen oral solutions of varying concentrations, may result in accidental overdose and death.
• Oral liquid/solution safety and effectiveness in patients less than 2 years old have not been demonstrated.
• Oral pills have not been proven safe or effective in individuals under the age of 18.

You should not use this medicine if you are allergic to acetaminophen or hydrocodone, or if you have;

• Breathing problems
• A blockage in your intestines or stomach
• Severe asthma

Tell your doctor if you have ever had;

• Problems with your pancreas, gallbladder, and thyroid
• Seizures
• Breathing problems
• An alcohol or drug problem or addiction
• Sleep apnea
• Urination problems
• Liver disease
• Kidney problem or disease
• A head injury

WES 303 and pregnancy/breastfeeding

If you take opioid medications while pregnant, your kid may grow addicted to the substance. This may result in life-threatening withdrawal symptoms in the newborn after birth. Babies born addicted to opioids may need medical care for many weeks.

Breastfeeding is not permitted. This medication may enter the breast milk and induce sleepiness, respiratory difficulties, or death in a breastfeeding infant.

Avoid driving or operating equipment until you have a better understanding of how this medication may affect you. Dizziness and sleepiness may lead to falls, accidents, and serious injury. Do not consume alcohol.

Dangerous adverse effects including death are possible. Before using any other acetaminophen-containing medication, consult your doctor or pharmacist (sometimes abbreviated as APAP). Combining some drugs may result in a lethal overdose.

WES 303 should only be taken during pregnancy if the benefits exceed the hazards. This is why it is classified as pregnancy category C by the US FDA. It should be handled with extreme care.

Prolonged opiate usage during pregnancy may lead to physical dependency in the newborn; women should be informed about the danger of neonatal abstinence syndrome and ensure that proper treatment is provided.

Monitor newborns who have been exposed to opioid analgesics for symptoms of excessive sedation and respiratory depression.

Opioid analgesics pass through the placenta. The use of hydrocodone during childbirth may result in respiratory depression in the newborn baby.

Prolonged opiate usage during pregnancy might cause physical dependence in the neonate as well as neonatal opioid withdrawal syndrome soon after delivery.

The onset, length, and severity of the condition will differ depending on maternal usage (duration of use, timing, and quantity of last use) and the newborn's rate of elimination.

Although animal studies have shown deleterious effects at clinically relevant levels, acetaminophen has not been linked to significant congenital abnormalities.

Because of methodological constraints, epidemiologic studies do not reveal a link between oral acetaminophen and significant birth abnormalities, miscarriage, or unfavorable maternal or fetal outcomes when taken during pregnancy, but cannot prove the lack of any risk.

Fetotoxicity (lower fetal weight and length) and dosage-related increases in bone variations (reduced ossification and rudimentary rib alterations) were detected in pregnant rats taking the oral medicines at doses up to 0.88 times the maximum human daily dose (MHDD) during organogenesis.

When pregnant rats were administered oral medicines at dosages 1.2 times the maximum human daily dose throughout gestation, areas of necrosis in both the liver and kidney of pregnant rats and fetuses were found. Human pregnancy has no controlled data.

Chronic opioid usage may impair fertility; however, it is uncertain if these effects are reversible.

Animal reproduction studies have shown an unfavorable impact on the fetus, and there has been no appropriate and well-controlled human research, although possible advantages may justify the drug's usage in pregnant women despite potential dangers.

Breastfed babies of moms who consume opioids, particularly neonates, might develop sleepiness, CNS depression, and even death.

A study of 30 nursing mothers discovered mean and median hydrocodone baby daily doses of 3.9 and 2.1 mcg/kg, which equates to 2.4 and 1.6 percent of weight-adjusted maternal dosages, respectively.

Hydrocodone is broken down into six active metabolites, one of which is hydromorphone. The mean and median hydromorphone daily dosages were 2.1 and 0.3 mcg/kg, respectively.

Two women excreted much more hydromorphone than the others, suggesting that they are ultrarapid CYP450 2D6 metabolizers.

Given the value of the medicine to the mother, a choice should be taken to terminate breastfeeding or discontinue this drug. WES ingredients (acetaminophen and hydrocodone) are excreted in human milk.

Breastfed newborns should be examined for excessive sedation and respiratory depression; if the child has breathing problems or limpness, seek emergency medical assistance.

When a mother's drug usage or nursing is discontinued, her breastfed babies may experience withdrawal symptoms.

Make sure to discuss this with your healthcare provider before taking the WES 303 pill.
