Uses & Effectiveness
Insufficient Evidence for
- Cancer. One form of limonene (D-limonene) seems to build up in tumors in people with advanced cancer when it is taken by mouth. The high levels of limonene in the tumors may slow down the progress of the cancer, but their effect on the person's survival is uncertain.
- Obesity.
- Short-term swelling (inflammation) of the airways in the lungs (acute bronchitis).
- Other conditions.
Side Effects & Safety
When taken by mouth: Limonene is LIKELY SAFE when taken in food amounts. It is POSSIBLY SAFE for most people when taken by mouth in medicinal amounts for up to one year.When applied to the skin: Limonene is POSSIBLY SAFE when applied to the skin in amounts typically found in fragrances and personal hygiene products. It can cause skin reactions in people who are allergic to limonene.
Special Precautions & Warnings:
Pregnancy and breast-feeding: Limonene is LIKELY SAFE in food amounts, but there's not enough information to know if it's safe in larger medicinal amounts. Stay on the safe side and stick to the amounts found in foods.Interactions

Medications changed by the liver (Cytochrome P450 2C9 (CYP2C9) substrates) interacts with LIMONENE
Some medications are changed and broken down by the liver.
Limonene might increase how quickly the liver breaks down some medications. Taking limonene along with some medications that are changed by the liver can lead to a variety of effects and side effects. Before taking limonene talk to your healthcare provider if you take any medications that are changed by the liver.
Some of these medications that are changed by the liver include diclofenac (Cataflam, Voltaren), ibuprofen (Motrin), meloxicam (Mobic), and piroxicam (Feldene), amitriptyline (Elavil), warfarin (Coumadin), glipizide (Glucotrol), losartan (Cozaar), and others. -
Medications that decrease the break down of other medications by the liver (Cytochrome P450 2C19 (CYP2C19) inhibitors) interacts with LIMONENE
Limonene might be broken down by the liver. Taking limonene along with medications that decrease the break down of limonene in the liver might increase the effects and side effects of limonene.
Some medications that might decrease the breakdown of limonene in the liver include cimetidine (Tagamet), fluvoxamine (Luvox), omeprazole (Prilosec); ticlopidine (Ticlid), topiramate (Topamax), and others. -
Medications that decrease the break down of other medications by the liver (Cytochrome P450 2C9 (CYP2C9) inhibitors) interacts with LIMONENE
Limonene might be broken down by the liver. Taking limonene along with medications that decrease the break down of limonene in the liver might increase the effects and side effects of limonene.
Some medications that might decrease the breakdown of limonene in the liver include amiodarone (Cordarone), fluconazole (Diflucan), lovastatin (Mevacor), paroxetine (Paxil), zafirlukast (Accolate), and many others. -
Medications that increase the break down of other medications by the liver (Cytochrome P450 2C19 (CYP2C19) inducers) interacts with LIMONENE
Limonene might be broken down by the liver. Taking limonene along with medications that increase the break down of limonene in the liver might decrease the effects of limonene.
Some medications that might increase the breakdown of limonene in the liver include carbamazepine (Tegretol), prednisone (Deltasone), and rifampin (Rifadin, Rimactane). -
Medications that increase the break down of other medications by the liver (Cytochrome P450 2C9 (CYP2C9) inducers) interacts with LIMONENE
Limonene might be broken down by the liver. Taking limonene along with medications that increase the break down of limonene in the liver might decrease the effects of limonene.
Some medications that might increase the breakdown of limonene in the liver include rifampin (Rifadin, Rimactane) and secobarbital (Seconal).
Dosing
The appropriate dose of limonene depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for limonene. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
