What is Swenac SR?
Swenac SR is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and other symptoms of arthritis of the joints (eg, osteoarthritis), such as inflammation, swelling, stiffness, and joint pain. However, Swenac SR does not cure osteoarthritis and will help you only as long as you continue to use it.
Swenac SR topical 3% gel is also used to treat actinic keratosis, a skin problem that may become cancerous if not treated. The exact way that topical Swenac SR helps this condition is unknown.
Swenac SR topical solution is used to treat pain and swelling caused by osteoarthritis of the knees.
Swenac SR topical patch is used to treat acute pain caused by minor strains, sprains, and contusions (bruises).
Swenac SR is available only with your doctor's prescription.
Swenac SR indications

How should I use Swenac SR?
Use Swenac SR as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Swenac SR comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Swenac SR refilled.
- Do not apply Swenac SR to infected skin; open wounds; or red, swollen, or peeling skin.
- Wash your hands immediately before and after using Swenac SR.
- Wash the affected area and dry completely before using Swenac SR.
- To apply Swenac SR, dispense 10 drops at a time onto the knee or into your hand. Spread Swenac SR evenly around the front, back, and sides of the knee. Repeat until you have used the whole dose.
- Be sure that you cover your entire knee with your dose of Swenac SR. Do not use more than the recommended amount.
- Do not apply sunscreens, cosmetics, insect repellants, other topical medicines, or any other substance to the treated area until it is completely dry.
- Do not put on clothes over the treated area until it is completely dry.
- Do not wrap, bandage, or apply heat to the treated area.
- Let the treated skin dry before touching it or letting it touch anyone else's skin.
- Do not shower, bathe, or wash the treated area for at least 30 minutes after you use Swenac SR.
- If you miss a dose of Swenac SR, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use Swenac SR.

Swenac SR description
A non-steroidal anti-inflammatory agent (NSAID) with antipyretic and analgesic actions. It is primarily available as the sodium salt.
Swenac SR dosage
Carefully consider the potential benefits and risks of Swenac SR extended-release tablets, and other treatment options before deciding to use Swenac SR extended-release tablets. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
After observing the response to initial therapy with Swenac SR extended-release tablets the dose and frequency should be adjusted to suit an individual patient’s needs.
For the relief of osteoarthritis, the recommended dosage is 100 mg daily.
For the relief of rheumatoid arthritis, the recommended dosage is 100 mg daily. In the rare patient where Swenac SR extended-release tablets 100 mg/day is unsatisfactory, the dose may be increased to 100 mg twice a day if the benefits outweigh the clinical risks of increased side effects.
Different formulations of Swenac SR (Swenac SR enteric-coated tablets; Swenac SR extended-release tablets; Swenac SR potassium immediate-release tablets) are not necessarily bioequivalent even if the milligram strength is the same.
Swenac SR interactions
See also:
What other drugs will affect Swenac SR?
Aspirin: Concomitant administration of Swenac SR and aspirin is not recommended because Swenac SR is displaced from its binding sites during the concomitant administration of aspirin, resulting in lower plasma concentrations, peak plasma levels, and AUC values.
Anticoagulants: While studies have not shown Swenac SR to interact with anticoagulants of the warfarin type, caution should be exercised, nonetheless, since interactions have been seen with other NSAIDs. Because prostaglandins play an important role in hemostasis, and NSAIDs affect platelet function as well, concurrent therapy with all NSAIDs, including Swenac SR, and warfarin requires close monitoring of patients to be certain that no change in their anticoagulant dosage is required.
Digoxin, Methotrexate, Cyclosporine: Swenac SR, like other NSAIDs, may affect renal prostaglandins and increase the toxicity of certain drugs. Ingestion of Swenac SR may increase serum concentrations of digoxin and methotrexate and increase cyclosporineís nephrotoxicity. Patients who begin taking Swenac SR or who increase their Swenac SR dose or any other NSAID while taking digoxin, methotrexate, or cyclosporine may develop toxicity characteristics for these drugs. They should be observed closely, particularly if renal function is impaired. In the case of digoxin, serum levels should be monitored.
Lithium: Swenac SR decreases lithium renal clearance and increases lithium plasma levels. In patients taking Swenac SR and lithium concomitantly, lithium toxicity may develop.
Oral Hypoglycemics:
Swenac SR does not alter glucose metabolism in normal subjects nor does it alter the effects of oral hypoglycemic agents. There are rare reports, however, from marketing experiences, of changes in effects of insulin or oral hypoglycemic agents in the presence of Swenac SR that necessitated changes in the doses of such agents. Both hypo- and hyperglycemic effects have been reported. A direct causal relationship has not been established, but physicians should consider the possibility that Swenac SR may alter a diabetic patientís response to insulin or oral hypoglycemic agents.
Diuretics: Swenac SR and other NSAIDs can inhibit the activity of diuretics. Concomitant treatment with potassium-sparing diuretics may be associated with increased serum potassium levels.
Other Drugs: In small groups of patients (7-10/interaction study), the concomitant administration of azathioprine, gold, chloroquine, D-penicillamine, prednisolone, doxycycline, or digitoxin did not significantly affect the peak levels and AUC values of Swenac SR. Phenobarbital toxicity has been reported to have occurred in a patient on chronic phenobarbital treatment following the initiation of Swenac SR therapy.
Protein Binding
In vitro, Swenac SR interferes minimally or not at all with the protein binding of salicylic acid (20% decrease in binding), tolbutamide, prednisolone (10% decrease in binding), or warfarin. Benzylpenicillin, ampicillin, oxacillin, chlortetracycline, doxycycline, cephalothin, erythromycin, and sulfamethoxazole have no influence in vitro on the protein binding of Swenac SR in human serum.
Drug/Laboratory Test Interactions
Effect on Blood Coagulation: Swenac SR increases platelet aggregation time but does not affect bleeding time, plasma thrombin clotting time, plasma fibrinogen, or factors V and VII to XII. Statistically significant changes in prothrombin and partial thromboplastin times have been reported in normal volunteers. The mean changes were observed to be less than 1 second in both instances, however, and are unlikely to be clinically important. Swenac SR is a prostaglandin synthetase inhibitor, however, and all drugs that inhibit prostaglandin synthesis interfere with platelet function to some degree; therefore, patients who may be adversely affected by such an action should be carefully observed.

What are the possible side effects of Swenac SR?
Ocular
Transient burning and stinging were reported in approximately 15% of patients across studies with the use of Swenac SR ophthalmic solution, 0.1%. In cataract surgery studies, keratitis was reported in up to 28% of patients using Swenac SR ophthalmic solution, 0.1%, although in many of these cases keratitis was initially noted prior to the initiation of treatment. Elevated intraocular pressure following cataract surgery was reported in approximately 15% of patients undergoing cataract surgery. Lacrimation complaints were reported in approximately 30% of case studies undergoing incisional refractive surgery. The following adverse reactions were reported in approximately 10% or less of the patients: abnormal vision, acute elevated IOP, blurred vision, conjunctivitis, corneal deposits, corneal edema, corneal opacity, corneal lesions, discharge, eyelid swelling, eye pain, injection (redness), iritis, irritation, itching, lacrimation disorder, and ocular allergy.
Systemic
The following adverse reactions were reported in 3% or less of the patients: abdominal pain, asthenia, chills, dizziness, facial edema, fever, headache, insomnia, nausea, pain, rhinitis, viral infection and vomiting.
Clinical Practice
The following reactions have been identified during postmarketing use of topical Swenac SR ophthalmic solution, 0.1% in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. The reactions, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to topical Swenac SR ophthalmic solution, 0.1%, or a combination of these factors, include corneal erosion, corneal infiltrates, corneal perforation, corneal thinning, corneal ulceration and epithelilal breakdown.
