Ask your child's doctor if you don't know how much medication to give your child. Acetaminophen comes in combination with other medications to treat cough and cold symptoms. Ask your doctor or pharmacist for advice on which product is best for your symptoms. Check nonprescription cough and cold product labels carefully before using two or more products at the same time. These products may contain the same active ingredient s and taking them together could cause you to receive an overdose.
This is especially important if you will be giving cough and cold medications to a child. Place the orally disintegrating tablet 'Meltaways' in your mouth and allow to dissolve or chew it before swallowing. Shake the suspension well before each use to mix the medication evenly.
Always use the measuring cup or syringe provided by the manufacturer to measure each dose of the solution or suspension. Do not switch dosing devices between different products; always use the device that comes in the product packaging. Stop taking acetaminophen and call your doctor if your symptoms get worse, you develop new or unexpected symptoms, including redness or swelling, your pain lasts for more than 10 days, or your fever gets worse or lasts more than 3 days. Also stop giving acetaminophen to your child and call your child's doctor if your child develops new symptoms, including redness or swelling, or your child's pain lasts for longer than 5 days, or fever get worse or lasts longer than 3 days.
Do not give acetaminophen to a child who has a sore throat that is severe or does not go away, or that occurs along with fever, headache, rash, nausea, or vomiting. Call the child's doctor right away, because these symptoms may be signs of a more serious condition. Acetaminophen may also be used in combination with aspirin and caffeine to relieve the pain associated with migraine headache.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. This medication is usually taken as needed. If your doctor has told you to take acetaminophen regularly, take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Acetaminophen may cause other side effects. Call your doctor if you have any unusual problems while you are taking this medication. Keep this medication in the container it came in, tightly closed, and out of reach of children. In therapeutic doses paracetamol is a safe analgesic, but in overdosage it can cause severe hepatic necrosis. Its rate of oral absorption is predominantly dependent on the rate of gastric emptying, being delayed by food, propantheline, pethidine and diamorphine and enhanced by metoclopramide.
Paracetamol is also well absorbed from the rectum. The trial medication paracetamol, ibuprofen, and placebo was packed and masked by the Pharmacy of the Capital Region, Herlev, Denmark. A dose of trial medication consisted of 3 identical opaque capsules. Patients, staff, investigators, outcome assessors, and the statistician were blinded to the intervention. Based on the masked results, abstracts were written and agreed upon by the trial steering committee April 6, before revealing the identity of the groups Supplement 2.
The patients had either cementless or cemented components inserted. Patients received spinal preferred or general anesthesia. For spinal anesthesia, bupivacaine plain mg was used, combined with continuous propofol infusion if sedation was needed. For general anesthesia, propofol and remifentanil were preferred, and at the end of surgery, intravenous sufentanil 0.
According to the protocol, additional boluses of 2-mg morphine on patient request were allowed during the first postoperative hour. These additional dosages were added to the total PCA morphine consumption for the primary outcome. If any other opioid was administered during the first 24 hours postoperatively due to mistake, malfunction of PCA pump, or other such problem , this was converted to morphine equivalents and added to the PCA morphine.
No pain medication including peripheral regional anesthesia other than the trial medication and the PCA morphine was allowed. Patients usually treated with gabapentinoids, glucocorticoids, selective serotonin reuptake inhibitors, tramadol, or codeine continued these medications during the intervention period hours.
The trial had 2 co—primary outcomes: total morphine consumption for the first 24 hours postoperatively and proportion of patients with 1 or more modified SAEs from the surgery to 90 days postoperatively.
The outcome of proportion of modified SAEs was defined as SAE according to ICH-GCP guidelines 14 defined as any untoward medical occurrence that results in death; is life-threatening; requires hospitalization or prolongation of hospitalization; or results in significant or persistent disability or incapacity, birth defects, or a medical intervention to prevent 1 of the before-mentioned outcomes excluding prolongation of hospitalization because these could not be adjudicated because of differences in length of stay.
Data regarding postoperative hospitalization were collected from Danish National Patient Registry, and vital status was collected from the Danish Civil Registration System.
All patients were interviewed by phone at 90 days postoperatively to investigate if there had been any events requiring medical intervention since surgery.
The exploratory outcomes were level of nausea, sedation, dizziness none, mild, moderate, and severe; patients indicated their own level ; vomiting number of vomiting episodes ; use of antiemetic ondansetron, milligrams ; blood loss during the surgical procedure milliliters ; and days alive and outside hospital within 90 days postrandomization. To maintain an overall familywise error rate of less than. Furthermore, the threshold for type I error rate was adjusted for the pairwise comparisons between the 4 groups 6 comparisons to.
Because there was no prior literature clearly identifying what a minimal clinically important difference MCID would be for the reduction of morphine use after surgery, we established the MCID based on our clinical experience.
For the co—primary outcome of the proportion of modified SAEs, a power of 0. Analyses were performed by an independent statistician J. The primary analyses were by the intention-to-treat principle and the primary analysis population was composed of randomized patients who underwent THA surgery.
The primary analysis of the co—primary outcome of morphine consumption was pairwise comparisons between groups using the Van Elteren test, due to nonnormally distributed data.
Secondary analyses included adjusted analyses for sex, age, prior use of NSAIDs, and prior use of paracetamol and analyses based on the strictly per-protocol population. All analyses were stratified for site. For the primary and secondary outcomes, site and variables used in the adjusted analyses were tested for interaction with intervention groups by adding an interaction term in the generalized estimating equation model using the STATA 15 command XTGEE.
Data are presented as means with standard deviations for normally distributed data and medians with The level of significance and corresponding confidence interval were. From December to October , a total of participants were enrolled in this trial. Following randomization, surgery was canceled for 3 participants; thus, patients were included in the primary analysis population Figure 1. The demographic, surgical, and anesthesia characteristics Table 1 were comparable between groups.
Multiple imputation was not used for any outcome because there were few missing data. The final date of follow-up was January 1, In the pairwise comparisons Table 2 , the median difference was 16 mg The difference was 8 mg The differences between the paracetamol plus ibuprofen group and the half-strength paracetamol plus ibuprofen group 8 mg [ There was no significant difference between the ibuprofen-alone group and the half-strength paracetamol plus ibuprofen group 2 mg [ For the comparison between the paracetamol plus ibuprofen group and the half-strength paracetamol plus ibuprofen group, we found a qualitative and statistically significant interaction between intervention and site eTables 1 and 2 in Supplement 2.
The corresponding RR was 1. At 6 hours, the only statistically significant difference in pain scores Table 3 was between the parecetamol plus ibuprofen group and the paracetamol-alone group at rest 8 mm [ At 24 hours, the paracetamol plus ibuprofen group had lower pain scores than the paracetamol-alone group 11 mm [ At 24 hours, the paracetamol plus ibuprofen group had lower pain scores at rest than all other groups compared with the paracetamol-alone group 11 mm [ There were no significant differences in adverse events in any pairwise comparison Table 3 ; eTable 5 in Supplement 2.
Key exploratory findings were reduced risk of nausea at 24 hours for group paracetamol plus ibuprofen group compared with all other groups paracetamol-alone group [RR, 0. Key findings from the secondary analyses were that the differences in morphine consumption between the paracetamol plus ibuprofen group and the ibuprofen-alone group were not statistically significant in adjusted analyses and analyses in the per-protocol population, contrary to the main unadjusted analysis in the primary analysis population.
All exploratory outcomes and results from secondary analyses are found online eTables 6 to 13 in Supplement 2. This trial demonstrated that a combination of paracetamol mg and ibuprofen mg resulted in a clinically relevant reduction in morphine consumption compared with paracetamol mg alone on the first postoperative day after THA.
For all other comparisons, the differences in morphine consumption were less than the predefined minimal clinically relevant difference of 10 mg the difference in morphine consumption between the paracetamol [ mg] plus ibuprofen [ mg] group vs the ibuprofen [ mg]—alone group was 6 mg. Further, the trial showed a substantial proportion of patients with 1 or more SAEs within 90 days after surgery; however, there was no statically significant difference in patients randomized to receuve ibuprofen compared with patients randomized to receive paracetamol only.
