Solal Quercetin is a flavonoid extracted from fruit. It supports healthy immune function and has anti-allergy and antiviral effects. Quercetin also reduces the risk of death from coronary artery disease. Ordinarily quercetin is not well absorbed from the intestine, but bromelain enzymes are included in SOLAL Quercetin for improved quercetin absorption and effectiveness.

Side effects include headache, allergy, gastrointestinal upset and tingling of the extremities. Doses exceeding 6 capsules per day may be damaging to the kidney.
Cyclosporine: Quercetin increases plasma levels and prolongs the half-life of cyclosporine.
Cytochrome P450 2C8, 2C9, 2D6, 3A4: Preliminary evidence indicated that quercetin inhibits these enzymes and this may lead to reduced elimination and higher plasma levels of medicines metabolised by these substrates.
Some medicines that could be affected include: amiodarone, docetaxel, tretinoins, repaglinide, verapamil, celecoxib, diclofenac, fluvastatin, glipizide, ibuprofen, irbesartan, losartan, phenytoin, piroxicam, tamoxifen, tolbutamide, torsemide, warfarin, amitriptyline, codeine, flecainide, haloperidol, imipramine, metoprolol, ondansetron, paroxetine, risperidone, tramadol, venlafaxine, calcium channel blockers, chemotherapeutic agents antifungals, glucocorticoids, alfentanil, fentanyl, losartan, fluoxetine, midazolam, omeprazole, lansoprazole, propranolol, fexofenadine, amitriptyline, amiodarone, citalopram, sertraline and numerous others.
P-Glycoprotein substrates: There is preliminary evidence that the quercetin inhibits the gastrointestinal P-glycoprotein efflux pump. This may increase the bioavailability and the serum levels of drugs transported by the pump. Medicines transported by the pump include: paclitaxel, diltiazem, cyclosporine, saquinavir, digoxin, chemotherapeutic agents (etoposide, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), protease inhibitors (amprenavir, indinavir, nelfinavir), H2 antagonists (cimetidine, ranitidine), verapamil, corticosteroids, erythromycin, zexofenadine, loperamide, quinidine, and others.
Quinolone antibiotics: Quercetin might competitively inhibit quinolone antibiotics by binding to the DNA gyrase site on bacteria. Quinolones include: ciprofloxacin, levofloxacin, ofloxacin, moxifloxacin, gatifloxacin and others.
Pineapple allergy: Individuals allergic to pineapples should use caution, as bromelain is made from pineapples.
