WARNINGS Reye’s Syndrome may develop in individuals who have chicken pox, influenza, or flu symptoms. Some studies suggest possible association between the development of Reye’s Syndrome and the use of medicines containing salicylate or aspirin. Orphenadrine Citrate, Aspirin and Caffeine Tablets 25 mg/ 385 mg/ 30 mg contain aspirin and therefore are not recommended for use in patients with chicken pox, influenza, or flu symptoms. Orphenadrine Citrate, Aspirin and Caffeine Tablets may impair the ability of the patient to engage in potentially hazardous activities such as operating machinery or driving a motor vehicle; ambulatory patients should therefore be cautioned accordingly. Aspirin should be used with extreme caution in the presence of peptic ulcers and coagulation abnormalities. Pregnancy Risk Summary Use of NSAIDs, including aspirin, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. Because of these risks, limit dose and duration of Orphenadrine Citrate, Aspirin and Caffeine Tablets use between about 20 and 30 weeks of gestation, and avoid Orphenadrine Citrate, Aspirin and Caffeine Tablets use at about 30 weeks of gestation and later in pregnancy [ see WARNINGS; Fetal Toxicity ]. Premature Closure of Fetal Ductus Arteriosus Use of NSAIDs, including aspirin, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Oligohydramnios/Neonatal Renal Impairment Use of NSAIDs at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. Data from observational studies regarding other potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as aspirin, resulted in increased pre- and post-implantation loss. Prostaglandins also have been shown to have an important role in fetal kidney development. In published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses. The estimated background risk of major birth defects and miscarriage for the indicated population(s) is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Premature Closure of Fetal Ductus Arteriosus: Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy, because NSAIDs, including Orphenadrine Citrate, Aspirin and Caffeine Tablets, can cause premature closure of the fetal ductus arteriosus (see WARNINGS; Fetal Toxicity ) . Oligohydramnios/Neonatal Renal Impairment If an NSAID is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. If Orphenadrine Citrate, Aspirin and Caffeine Tablets treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. If oligohydramnios occurs, discontinue Orphenadrine Citrate, Aspirin and Caffeine Tablets and follow up according to clinical practice (see WARNINGS; Fetal Toxicity ) . Data Human Data Premature Closure of Fetal Ductus Arteriosus: Published literature reports that the use of NSAIDs at about 30 weeks of gestation and later in pregnancy may cause premature closure of the fetal ductus arteriosus. Oligohydramnios/Neonatal Renal Impairment: Published studies and postmarketing reports describe maternal NSAID use at about 20 weeks gestation or later in pregnancy associated with fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation. In many cases, but not all, the decrease in amniotic fluid was transient and reversible with cessation of the drug. There have been a limited number of case reports of maternal NSAID use and neonatal renal dysfunction without oligohydramnios, some of which were irreversible. Some cases of neonatal renal dysfunction required treatment with invasive procedures, such as exchange transfusion or dialysis. Methodological limitations of these postmarketing studies and reports include lack of a control group; limited information regarding dose, duration, and timing of drug exposure; and concomitant use of other medications. These limitations preclude establishing a reliable estimate of the risk of adverse fetal and neonatal outcomes with maternal NSAID use. Because the published safety data on neonatal outcomes involved mostly preterm infants, the generalizability of certain reported risks to the full-term infant exposed to NSAIDs through maternal use is uncertain. Usage in Children: The safe and effective use of this drug in children has not been established. Usage of this drug in children under 12 years of age is not recommended. Fetal Toxicity Premature Closure of Fetal Ductus Arteriosus: Avoid use of NSAIDs, including Orphenadrine Citrate, Aspirin and Caffeine Tablets, in pregnant women at about 30 weeks gestation and later. NSAIDs including Orphenadrine Citrate, Aspirin and Caffeine Tablets, increase the risk of premature closure of the fetal ductus arteriosus at approximately this gestational age. Oligohydramnios/Neonatal Renal Impairment: Use of NSAIDs, including Orphenadrine Citrate, Aspirin and Caffeine Tablets, at about 20 weeks gestation or later in pregnancy may cause fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation. Oligohydramnios is often, but not always, reversible with treatment discontinuation. Complications of prolonged oligohydramnios may, for example, include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures such as exchange transfusion or dialysis were required. If NSAID treatment is necessary between about 20 weeks and 30 weeks gestation, limit Orphenadrine Citrate, Aspirin and Caffeine Tablets use to the lowest effective dose and shortest duration possible. Consider ultrasound monitoring of amniotic fluid if Orphenadrine Citrate, Aspirin and Caffeine Tablets treatment extends beyond 48 hours. Discontinue Orphenadrine Citrate, Aspirin and Caffeine Tablets if oligohydramnios occurs and follow up according to clinical practice [ see PRECAUTIONS; Pregnancy ] . Serious Skin Reactions NSAIDs, including aspirin, a component of Orphenadrine Citrate, Aspirin and Caffeine Tablets, can cause serious skin adverse reactions such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. NSAIDs can also cause fixed drug eruption (FDE). FDE may present as a more severe variant known as generalized bullous fixed drug eruption (GBFDE), which can be life-threatening. These serious events may occur without warning. Inform patients about the signs and symptoms of serious skin reactions, and to discontinue the use of Orphenadrine Citrate, Aspirin and Caffeine Tablets at the first appearance of skin rash or any other sign of hypersensitivity. Orphenadrine Citrate, Aspirin and Caffeine Tablets is contraindicated in patients with previous serious skin reactions to NSAIDs [ see Contraindications ]. Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported in patients taking NSAIDs such as Orphenadrine Citrate, Aspirin and Caffeine Tablets. Some of these events have been fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling. Other clinical manifestations may include hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis. Sometimes symptoms of DRESS may resemble an acute viral infection. Eosinophilia is often present. Because this disorder is variable in its presentation, other organ systems not noted here may be involved. It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident. If such signs or symptoms are present, discontinue Orphenadrine Citrate, Aspirin and Caffeine Tablets and evaluate the patient immediately.
Adverse reactions▾
ADVERSE REACTIONS Side effects of Orphenadrine Citrate, Aspirin and Caffeine Tablets are those seen with aspirin and caffeine or those usually associated with mild anti-cholinergic agents. These may include tachycardia, palpitation, urinary hesitancy or retention, dry mouth, blurred vision, dilation of the pupil, increased intraocular tension, weakness, nausea, vomiting, headache, dizziness, constipation, drowsiness, and rarely, urticaria and other dermatosis. Infrequently, an elderly patient may experience some degree of confusion. Mild central excitation and occasional hallucinations may be observed. These mild side effects can usually be eliminated by reduction in dosage. One case of aplastic anemia associated with the use of orphenadrine citrate, aspirin and caffeine has been reported. No causal relationship has been established. Rare G.I. hemorrhage due to aspirin content may be associated with the administration of Orphenadrine Citrate, Aspirin and Caffeine Tablets. Some patients may experience transient episodes of light-headedness, dizziness or syncope. Orphenadrine Citrate, Aspirin and Caffeine Tablets may also cause exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), toxic epidermal necrosis (TEN), and fixed drug eruption (FDE) ( see WARNINGS ).
