Use of colestipol for six months has been shown to significantly lower blood levels of carotenoids including beta-carotene.

This interaction is based on this drug belonging to a drug class. While this drug may differ from the text and references below, drugs within this class work in a similar way and this interaction is applicable to drugs within the same class.

Omeprazole, a drug closely related to lansoprazole, taken for seven days led to a near-total loss of stomach acid in healthy people and interfered with the absorption of a single administration of 120 mg of beta-carotene. It is unknown whether repeated administration of beta-carotene would overcome this problem or if absorption of carotenoids from food would be impaired. Persons taking omeprazole and related acid-blocking drugs for long periods may want to have carotenoid blood levels checked, eat plenty of fruits and vegetables, and consider supplementing with carotenoids.

Colchicine has been associated with impaired absorption of beta-carotene, fat, lactose (milk sugar), potassium, and sodium.

Mineral oil has interfered with the absorption of many nutrients, including beta-carotene, phosphorus, potassium, and vitamins A, D, K, and E in some, but not all, research. Taking mineral oil on an empty stomach may reduce this interference. It makes sense to take a daily multivitamin-mineral supplement two hours before or after mineral oil. It is important to read labels, because many multivitamins do not contain vitamin K or contain inadequate (less than 100 mcg per day) amounts.

Neomycin can decrease absorption or increase elimination of many nutrients, including calcium, carbohydrates, beta-carotene, fats, folic acid, iron, magnesium, potassium, sodium, and vitamin A, vitamin B12, vitamin D, and vitamin K. Surgery preparation with oral neomycin is unlikely to lead to deficiencies. It makes sense for people taking neomycin for more than a few days to also take a multivitamin-mineral supplement.

One well-controlled study showed that taking orlistat greatly reduces the absorption of beta-carotene. Therefore, individuals taking orlistat for long periods of time should probably supplement with beta-carotene.

Chemotherapy frequently causes mouth sores. In one trial, people were given approximately 400,000 IU of beta-carotene per day for three weeks and then 125,000 IU per day for an additional four weeks. Those taking beta-carotene still suffered mouth sores, but the mouth sores developed later and tended to be less severe than mouth sores that formed in people receiving the same chemotherapy without beta-carotene.

In a study of chemotherapy-induced mouth sores, six of nine patients who applied vitamin E directly to their mouth sores had complete resolution of the sores compared with one of nine patients who applied placebo. Others have confirmed the potential for vitamin E to help people with chemotherapy-induced mouth sores. Applying vitamin E only once per day was helpful to only some groups of patients in another trial, and not all studies have found vitamin E to be effective. Until more is known, if vitamin E is used in an attempt to reduce chemotherapy-induced mouth sores, it should be applied topically twice per day and should probably be in the tocopherol (versus tocopheryl) form.

In a preliminary study, the addition of oral vitamin E (300 IU per day) to cisplatin chemotherapy significantly reduced the incidence of drug-induced damage to the nervous system (neurotoxicity). A similar protective effect was seen in another trial in which 600 IU of vitamin E per day was used.

Applying vitamin E only once per day was helpful to only some groups of patients in another trial, and not all studies have found vitamin E to be effective. Until more is known, if vitamin E is used in an attempt to reduce chemotherapy-induced mouth sores, it should be applied topically twice per day and should probably be in the tocopherol (versus tocopheryl) form.

Chemotherapy frequently causes mouth sores. In one trial, people were given approximately 400,000 IU of beta-carotene per day for three weeks and then 125,000 IU per day for an additional four weeks. Those taking beta-carotene still suffered mouth sores, but the mouth sores developed later and tended to be less severe than mouth sores that formed in people receiving the same chemotherapy without beta-carotene.

In a study of chemotherapy-induced mouth sores, six of nine patients who applied vitamin E directly to their mouth sores had complete resolution of the sores compared with one of nine patients who applied placebo. Others have confirmed the potential for vitamin E to help people with chemotherapy-induced mouth sores. Applying vitamin E only once per day was helpful to only some groups of patients in another trial, and not all studies have found vitamin E to be effective. Until more is known, if vitamin E is used in an attempt to reduce chemotherapy-induced mouth sores, it should be applied topically twice per day and should probably be in the tocopherol (versus tocopheryl) form. In another study, supplementation with vitamin E orally (600 IU per day) reduced the incidence of paclitaxel-induced nerve damage.

In a preliminary study, the addition of oral vitamin E (300 IU per day) to cisplatin chemotherapy significantly reduced the incidence of drug-induced damage to the nervous system (neurotoxicity). A similar protective effect was seen in another trial in which 600 IU of vitamin E per day was used.

Some people taking quinidine develop sensitivity to ultraviolet radiation from the sun. In a preliminary study, three people with quinidine-induced skin inflammation were able to tolerate intense sun exposure without recurrence of the rash after supplementing with 90–180 mg of beta-carotene each day. Further research is needed to confirm that people taking quinidine can prevent side effects by supplementing with beta-carotene.
