Rayor side effects (more detail)

Side effects of Rayor in details

A side effect of any drug can be defined as the unwanted or undesired effect produced by the drug. The side effect can be major or in few medications minor that can be ignored. Side effects not only vary from drug to drug, but it also depends on the dose of the drug, the individual sensitivity of the person, brand or company which manufactures it. If side effects overweigh the actual effect of the medicine, it may be difficult to convince the patient to take the drug. Few patients get specific side effects to specific drugs; in that case, a doctor replaces the drug with another. If you feel any side effect and it troubles you, do not forget to share with your healthcare practitioner.

During clinical studies and the foreign postmarketing experience with Rayor® (Rayor mesylate, USP) Nasal Spray there have been no fatalities due to cardiac events.

Serious cardiac events, including some that have been fatal, have occurred following use of the parenteral form of Rayor mesylate (D.H.E. 45® Injection), but are extremely rare. Events reported have included coronary artery vasospasm, transient myocardial ischemia, myocardial infarction, ventricular tachycardia, and ventricular fibrillation..

Fibrotic complications have been reported in association with long term use of injectable Rayor mesylate.

Incidence in Controlled Clinical Trials

Of the 1,796 patients and subjects treated with Rayor® (Rayor mesylate, USP) Nasal Spray doses 2 mg or less in U.S. and foreign clinical studies, 26 (1.4%) discontinued because of adverse events. The adverse events associated with discontinuation were, in decreasing order of frequency: rhinitis 13, dizziness 2, facial edema 2, and one each due to cold sweats, accidental trauma, depression, elective surgery, somnolence, allergy, vomiting, hypotension, and paraesthesia.

The most commonly reported adverse events associated with the use of Rayor® (Rayor mesylate, USP) Nasal Spray during placebo-controlled, double-blind studies for the treatment of migraine headache and not reported at an equal incidence by placebo-treated patients were rhinitis, altered sense of taste, application site reactions, dizziness, nausea, and vomiting. The events cited reflect experience gained under closely monitored conditions of clinical trials in a highly selected patient population. In actual clinical practice or in other clinical trials, these frequency estimates may not apply, as the conditions of use, reporting behavior, and the kinds of patients treated may differ.

Rayor® (Rayor mesylate, USP) Nasal Spray was generally well tolerated. In most instances these events were transient and self-limited and did not result in patient discontinuation from a study. The following table summarizes the incidence rates of adverse events reported by at least 1% of patients who received Rayor® (Rayor mesylate, USP) Nasal Spray for the treatment of migraine headaches during placebo-controlled, double-blind clinical studies and were more frequent than in those patients receiving placebo.

Other Adverse Events During Clinical Trials

In the paragraphs that follow, the frequencies of less commonly reported adverse clinical events are presented. Because the reports include events observed in open and uncontrolled studies, the role of Rayor® (Rayor mesylate, USP) Nasal Spray in their causation cannot be reliably determined. Furthermore, variability associated with adverse event reporting, the terminology used to describe adverse events, etc., limit the value of the quantitative frequency estimates provided. Event frequencies are calculated as the number of patients who used Rayor (Rayor mesylate spray) ® (Rayor mesylate, USP) Nasal Spray in placebo-controlled trials and reported an event divided by the total number of patients (n=1796) exposed to Rayor® (Rayor mesylate, USP) Nasal Spray. All reported events are included except those already listed in the previous table, those too general to be informative, and those not reasonably associated with the use of the drug. Events are further classified within body system categories and enumerated in order of decreasing frequency using the following definitions: frequent adverse events are defined as those occurring in at least 1/100 patients; infrequent adverse events are those occurring in 1/100 to 1/1,000 patients; and rare adverse events are those occurring in fewer than 1/1,000 patients.

Skin and Appendages: Infrequent: petechia, pruritus, rash, cold clammy skin; Rare: papular rash, urticaria, herpes simplex.

Musculoskeletal: Infrequent: cramps, myalgia, muscular weakness, dystonia; Rare: arthralgia, involuntary muscle contractions, rigidity.

Central and Peripheral Nervous System: Infrequent: confusion, tremor, hypoesthesia, vertigo; Rare: speech disorder, hyperkinesia, stupor, abnormal gait, aggravated migraine.

Autonomic Nervous System: Infrequent: increased sweating.

Special Senses: Infrequent: sense of smell altered, photophobia, conjunctivitis, abnormal lacrimation, abnormal vision, tinnitus, earache; Rare: eye pain.

Psychiatric: Infrequent: nervousness, euphoria, insomnia, concentration impaired; Rare: anxiety, anorexia, depression.

Gastrointestinal: Infrequent: abdominal pain, dyspepsia, dysphagia, hiccup; Rare: increased salivation, esophagospasm.

Cardiovascular: Infrequent: edema, palpitation, tachycardia; Rare: hypotension, peripheral ischemia, angina.

Respiratory System: Infrequent: dyspnea, upper respiratory tract infections; Rare: bronchospasm, bronchitis, pleural pain, epistaxis.

Urinary System: Infrequent: increased frequency of micturition, cystitis.

Reproductive, Female: Rare: pelvic inflammation, vaginitis.

Body as a Whole - General: Infrequent: feeling cold, malaise, rigors, fever, periorbital edema; Rare: flu-like symptoms, shock, loss of voice, yawning.

Application Site: Infrequent: local anesthesia.

Post-introduction Reports

Voluntary reports of adverse events temporally associated with Rayor products used in the management of migraine that have been received since the introduction of the injectable formulation are included in this section save for those already listed above. Because of their source (open and uncontrolled clinical use), whether or not events reported in association with the use of Rayor are causally related to it cannot be determined. There have been reports of pleural and retroperitoneal fibrosis in patients following prolonged daily use of injectable Rayor mesylate. Rayor® (Rayor mesylate, USP) Nasal Spray is not recommended for prolonged daily use.

Drug Abuse And Dependence

Currently available data have not demonstrated drug abuse or psychological dependence with Rayor. However, cases of drug abuse and psychological dependence in patients on other forms of ergot therapy have been reported. Thus, due to the chronicity of vascular headaches, it is imperative that patients be advised not to exceed recommended dosages.

What is the most important information I should know about Rayor?

Rayor contraindications

Contraindication can be described as a special circumstance or a disease or a condition wherein you are not supposed to use the drug or undergo particular treatment as it can harm the patient; at times, it can be dangerous and life threatening as well. When a procedure should not be combined with other procedure or when a medicine cannot be taken with another medicine, it is called Relative contraindication. Contraindications should be taken seriously as they are based on the relative clinical experience of health care providers or from proven research findings.

There have been a few reports of serious adverse events associated with the coadministration of Rayor and potent CYP 3A4 inhibitors, such as protease inhibitors and macrolide antibiotics, resulting in vasospasm that led to cerebral ischemia and/or ischemia of the extremities. The use of potent CYP 3A4 inhibitors (ritonavir, nelfinavir, indinavir, erythromycin, clarithromycin, troleandomycin, ketoconazole, itraconazole) with Rayor is, therefore contraindicated.

Rayor® (Rayor mesylate, USP) Nasal Spray should not be given to patients with ischemic heart disease (angina pectoris, history of myocardial infarction, or documented silent ischemia) or to patients who have clinical symptoms or findings consistent with coronary artery vasospasm including Prinzmetal's variant angina.

Because Rayor® (Rayor mesylate, USP) Nasal Spray may increase blood pressure, it should not be given to patients with uncontrolled hypertension.

Rayor® (Rayor mesylate, USP) Nasal Spray, 5-HT1 agonists (e.g., sumatriptan), ergotamine-containing or ergot-type medications or methysergide should not be used within 24 hours of each other.

Rayor® (Rayor mesylate, USP) Nasal Spray should not be administered to patients with hemiplegic or basilar migraine.

In addition to those conditions mentioned above, Rayor® (Rayor mesylate, USP) Nasal Spray is also contraindicated in patients with known peripheral arterial disease, sepsis, following vascular surgery, and severely impaired hepatic or renal function.

Rayor® (Rayor mesylate, USP) Nasal Spray may cause fetal harm when administered to a pregnant woman. Rayor possesses oxytocic properties and, therefore, should not be administered during pregnancy. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.

There are no adequate studies of Rayor in human pregnancy, but developmental toxicity has been demonstrated in experimental animals. In embryofetal development studies of Rayor mesylate nasal spray, intranasal administration to pregnant rats throughout the period of organogenesis resulted in decreased fetal body weights and/or skeletal ossification at doses of 0.16 mg/day (associated with maternal plasma Rayor exposures [AUC] approximately 0.4 -1.2 times the exposures in humans receiving the MRDD of 4 mg) or greater. A no effect level for embryo-fetal toxicity was not established in rats. Delayed skeletal ossification was also noted in rabbit fetuses following intranasal administration of 3.6 mg/day (maternal exposures approximately 7 times human exposures at the MRDD) during organogenesis. A no effect level was seen at 1.2 mg/day (maternal exposures approximately 2.5 times human exposures at the MRDD). When Rayor mesylate nasal spray was administered intranasally to female rats during pregnancy and lactation, decreased body weights and impaired reproductive function (decreased mating indices) were observed in the offspring at doses of 0.16 mg/day or greater. A no effect level was not established. Effects on development occurred at doses below those that produced evidence of significant maternal toxicity in these studies. Rayor-induced intrauterine growth retardation has been attributed to reduced uteroplacental blood flow resulting from prolonged vasoconstriction of the uterine vessels and/or increased myometrial tone.

Rayor® (Rayor mesylate, USP) Nasal Spray is contraindicated in patients who have previously shown hypersensitivity to ergot alkaloids.

Rayor mesylate should not be used by nursing mothers.

Rayor mesylate should not be used with peripheral and central vasoconstrictors because the combination may result in additive or synergistic elevation of blood pressure.
