Robitussin Sinus Relief ophthalmic causes constriction of blood vessels in the eyes. It also enlarges the pupils, reduces the production of fluid in the eyes, and increases the amount of fluid that drains from the eyes.
Robitussin Sinus Relief ophthalmic available over-the-counter is used to relieve redness, burning, irritation, and dryness of the eye caused by wind, sun, and other minor irritants. Prescription-strength Robitussin Sinus Relief ophthalmic is used to constrict blood vessels in the eye and to dilate (make bigger) the pupil for conditions such as glaucoma, before surgery, and before eye examinations.
Robitussin Sinus Relief ophthalmic may also be used for purposes other than those listed in this medication guide.
Robitussin Sinus Relief indications
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.
Robitussin Sinus Relief is used for the temporary relief of stuffy nose, sinus, and ear symptoms caused by the common cold, flu, allergies, or other breathing illnesses (e.g., sinusitis, bronchitis). This medication works by decreasing swelling in the nose and ears, thereby lessening discomfort and making it easier to breathe.

Uses of Robitussin Sinus Relief in details
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.
Use: Labeled Indications
Hypotension/shock: Treatment of hypotension, vascular failure in shock. Note: Not recommended for routine use in the treatment of septic shock; use should be limited until more evidence demonstrating positive clinical outcomes becomes available (Rhodes 2017).
Cardiogenic shock: The 2017 American Heart Association (AHA) scientific statement for the Contemporary Management of Cardiogenic Shock recommends Robitussin Sinus Relief, if needed, be considered for initial vasoactive management of cardiogenic shock due to aortic stenosis, mitral stenosis, or dynamic left ventricular outflow tract (LVOT) obstruction (AHA [van Diepen 2017]).
Hypotension during anesthesia: As a vasoconstrictor in regional analgesia
Nasal congestion: As a decongestant [OTC]
Off Label Uses
Hypotension in patients with obstructive hypertrophic cardiomyopathy
Robitussin Sinus Relief is a pure alpha1 agonist that will increase systemic vascular resistance without increasing heart rate or contractility. This is advantageous in patients with obstructive hypertrophic cardiomyopathy and hypotension since increases in both heart rate and contractility may cause the obstruction to worsen, leading to a decrease in cardiac output. Other vasopressors like dopamine, epinephrine, and norepinephrine may increase contractility and/or heart rate. Additional trials may be necessary to further define the role of Robitussin Sinus Relief in this condition.
Based on the American Urological Association guidelines for the management of priapism, due to the low risk of cardiovascular side effects intracavernous injection of Robitussin Sinus Relief is recommended for ischemic priapism that persists following aspiration/irrigation.
Robitussin Sinus Relief description
Robitussin Sinus Relief is a sympathomimetic amine that acts predominantly on α-adrenergic receptors. It is mainly used to treat nasal congestion, but may also be useful in treating hypotension and shock, hypotension during spinal anaesthesia, prolongation of spinal anaesthesia, paroxysmal supraventricular tachycardia, symptomatic relief of external or internal hemorrhoids, and to increase blood pressure as an aid in the diagnosis of heart murmurs.
Robitussin Sinus Relief dosage
Prolonged exposure to air or strong light may cause oxidation and discoloration. Do not use if solution is brown or contains a precipitate.
Vasoconstriction and Pupil Dilatation
Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride 10 percent ophthalmic solutions are especially useful when rapid and powerful dilatation of the pupil and reduction of congestion in the capillary bed are desired. A drop of a suitable topical anesthetic may be applied, followed in a few minutes by 1 drop of the Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride 10 percent ophthalmic solutions on the upper limbus. The anesthetic prevents stinging and consequent dilution of the solution by lacrimation. It may occasionally be necessary to repeat the instillation after one hour, again preceded by the use of the topical anesthetic.
Uveitis: Posterior Synechiae
Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride 10 percent ophthalmic solutions may be used in patients with uveitis when synechiae are present or may develop. The formation of synechiae may be prevented by the use of the 10 percent ophthalmic solutions and atropine to produce wide dilatation of the pupil. It should be emphasized, however, that the vasoconstrictor effect of Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride may be antagonistic to the increase of local blood flow in uveal infection.
To free recently formed posterior synechiae, 1 drop of the 10 percent ophthalmic solutions may be applied to the upper surface of the cornea. On the following day, treatment may be continued if necessary. In the interim, hot compresses should be applied for five or ten minutes three times a day, with 1 drop of a 1 or 2 percent solution of atropine sulfate before and after each series of compresses.
In certain patients with glaucoma, temporary reduction of intraocular tension may be attained by producing vasoconstriction of the intraocular vessels; this may be accomplished by placing 1 drop of the 10 percent ophthalmic solutions on the upper surface of the cornea. This treatment may be repeated as often as necessary.
Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride may be used with miotics in patients with wide angle glaucoma. It reduces the difficulties experienced by the patient because of the small field produced by miosis, and still it permits and often supports the effect of the miotic in lowering the intraocular pressure. Hence, there may be marked improvement in visual acuity after using Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride in conjunction with miotic drugs.
When a short-acting mydriatic is needed for wide dilatation of the pupil before intraocular surgery, the 10 percent ophthalmic solutions or 2.5 percent ophthalmic solution may be applied topically from 30 to 60 minutes before the operation.
Prior to determination of refractive errors, Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride 2.5 percent ophthalmic solution may be used effectively with homatropine hydrobromide, atropine sulfate, or a combination of homatropine and cocaine hydrochloride.
For adults, a drop of the preferred cycloplegic is placed in each eye, followed in five minutes by 1 drop of Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride 2.5 percent ophthalmic solution and in ten minutes by another drop of the cycloplegic. In 50 to 60 minutes, the eyes are ready for refraction.
For children, a drop of atropine sulfate 1 percent is placed in each eye, followed in 10 to 15 minutes by 1 drop of Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride 2.5 percent ophthalmic solution and in five to ten minutes by a second drop of atropine sulfate 1 percent. In one to two hours, the eyes are ready for refraction.
For a “one application method,” Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride 2.5 percent ophthalmic solution may be combined with a cycloplegic to elicit synergistic action. The additive effect varies depending on the patient. Therefore, when using a “one application method,” it may be desirable to increase the concentration of the cycloplegic.
One drop of Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride 2.5 percent ophthalmic solution is placed in each eye. Sufficient mydriasis to permit examination is produced in 15 to 30 minutes. Dilatation lasts from one to three hours.
Provocative Test for Angle Block in Patients with Glaucoma:The 2.5 percent ophthalmic solution may be used as a provocative test when latent increased intraocular pressure is suspected. Tension is measured before application of Robitussin Sinus Relief (Robitussin Sinus Relief hydrochloride ophthalmic solution) hydrochloride and again after dilatation. A 3 to 5 mm of mercury rise in pressure suggests the presence of angle block in patients with glaucoma; however, failure to obtain such a rise does not preclude the presence of glaucoma from other causes.
Shadow Test (Retinoscopy): When dilatation of the pupil without cycloplegic action is desired for the shadow test, the 2.5 percent ophthalmic solution may be used alone.
Blanching Test:One or 2 drops of the 2.5 percent ophthalmic solution should be applied to the injected eye. After five minutes, examine for perilimbal blanching. If blanching occurs, the congestion is superficial and probably does not indicate iritis.
