Aspirin
In a study of people hospitalized with heart disease, those who had been taking aspirin were nearly twice as likely as nonusers to have a low or marginally low blood level of vitamin B12. That finding by itself does not prove that taking aspirin causes vitamin B12 deficiency. However, aspirin is known to damage the stomach in some cases, and the stomach plays a key role in vitamin B12 absorption (by secreting hydrochloric acid and intrinsic factor).

Vitamin B12
Carbamazepine
Anemia is an uncommon side effect experienced by people taking anticonvulsant drugs. Though many researches believe that low blood levels of folic acid are involved, the effects might be caused by a vitamin B12 deficiency. Deficiencies of folic acid and vitamin B12 can lead to nerve and mental problems. One study revealed that individuals on long-term anticonvulsant therapy, despite having no laboratory signs of anemia, had dramatically lower levels of vitamin B12 in their cerebrospinal fluid (the fluid that bathes the brain) when compared with people who were not taking seizure medications. Improvement in mental status and nerve function was observed in a majority of symptomatic individuals after taking 30 mcg of vitamin B12 daily for a few days. Another study found that long-term anticonvulsant therapy had no effect on blood levels of vitamin B12. The results of these two studies indicate that people taking anticonvulsant drugs might experience side effects of vitamin B12 deficiency, and that the deficiency is not easily detected by the usual blood tests. Therefore, individuals taking anticonvulsant drugs for several months or years might prevent nerve and mental problems by supplementing with vitamin B12.

Cimetidine
Hydrochloric acid is needed to release vitamin B12 from food so it can be absorbed by the body. Cimetidine, which reduces stomach acid, may decrease the amount of vitamin B12 available for the body to absorb. The vitamin B12 found in supplements is available to the body without the need for stomach acid. Lab tests can determine vitamin B12 levels in people.

Vitamin B12
Felbamate
Anemia is an uncommon side effect experienced by people taking anticonvulsant drugs. Though many researches believe that low blood levels of folic acid are involved, the effects might be caused by a vitamin B12 deficiency. Deficiencies of folic acid and vitamin B12 can lead to nerve and mental problems. One study revealed that individuals on long-term anticonvulsant therapy, despite having no laboratory signs of anemia, had dramatically lower levels of vitamin B12 in their cerebrospinal fluid (the fluid that bathes the brain) when compared with people who were not taking seizure medications. Improvement in mental status and nerve function was observed in a majority of symptomatic individuals after taking 30 mcg of vitamin B12 daily for a few days. Another study found that long-term anticonvulsant therapy had no effect on blood levels of vitamin B12. The results of these two studies indicate that people taking anticonvulsant drugs might experience side effects of vitamin B12 deficiency, and that the deficiency is not easily detected by the usual blood tests. Therefore, individuals taking anticonvulsant drugs for several months or years might prevent nerve and mental problems by supplementing with vitamin B12.

Levetiracetam
Anemia is an uncommon side effect experienced by people taking anticonvulsant drugs. Though many researches believe that low blood levels of folic acid are involved, the effects might be caused by a vitamin B12 deficiency. Deficiencies of folic acid and vitamin B12 can lead to nerve and mental problems. One study revealed that individuals on long-term anticonvulsant therapy, despite having no laboratory signs of anemia, had dramatically lower levels of vitamin B12 in their cerebrospinal fluid (the fluid that bathes the brain) when compared with people who were not taking seizure medications. Improvement in mental status and nerve function was observed in a majority of symptomatic individuals after taking 30 mcg of vitamin B12 daily for a few days. Another study found that long-term anticonvulsant therapy had no effect on blood levels of vitamin B12. The results of these two studies indicate that people taking anticonvulsant drugs might experience side effects of vitamin B12 deficiency, and that the deficiency is not easily detected by the usual blood tests. Therefore, individuals taking anticonvulsant drugs for several months or years might prevent nerve and mental problems by supplementing with vitamin B12.

Omeprazole
Omeprazole interferes with the absorption of vitamin B12 from food (though not from supplements) in some but not all studies. A true deficiency state, resulting in vitamin B12-deficiency anemia, has only been reported in one case. The fall in vitamin B12 status may result from the decrease in stomach acid required for vitamin B12 absorption from food caused by the drug. This problem may possibly be averted by drinking acidic juices when eating foods containing vitamin B12.
However, all people taking omeprazole need to either supplement with vitamin B12 or have their vitamin B12 status checked on a yearly basis. Even relatively small amounts of vitamin B12 such as 10–50 mcg per day, are likely to protect against drug induced vitamin depletion.

Oxcarbazepine
Anemia is an uncommon side effect experienced by people taking anticonvulsant drugs. Though many researches believe that low blood levels of folic acid are involved, the effects might be caused by a vitamin B12 deficiency. Deficiencies of folic acid and vitamin B12 can lead to nerve and mental problems. One study revealed that individuals on long-term anticonvulsant therapy, despite having no laboratory signs of anemia, had dramatically lower levels of vitamin B12 in their cerebrospinal fluid (the fluid that bathes the brain) when compared with people who were not taking seizure medications. Improvement in mental status and nerve function was observed in a majority of symptomatic individuals after taking 30 mcg of vitamin B12 daily for a few days. Another study found that long-term anticonvulsant therapy had no effect on blood levels of vitamin B12. The results of these two studies indicate that people taking anticonvulsant drugs might experience side effects of vitamin B12 deficiency, and that the deficiency is not easily detected by the usual blood tests. Therefore, individuals taking anticonvulsant drugs for several months or years might prevent nerve and mental problems by supplementing with vitamin B12.

Primidone
Anemia is an uncommon side effect experienced by people taking anticonvulsant drugs. Though many researches believe that low blood levels of folic acid are involved, the effects might be caused by a vitamin B12 deficiency. Deficiencies of folic acid and vitamin B12 can lead to nerve and mental problems. One study revealed that individuals on long-term anticonvulsant therapy, despite having no laboratory signs of anemia, had dramatically lower levels of vitamin B12 in their cerebrospinal fluid (the fluid that bathes the brain) when compared with people who were not taking seizure medications. Improvement in mental status and nerve function was observed in a majority of symptomatic individuals after taking 30 mcg of vitamin B12 daily for a few days. Another study found that long-term anticonvulsant therapy had no effect on blood levels of vitamin B12. The results of these two studies indicate that people taking anticonvulsant drugs might experience side effects of vitamin B12 deficiency, and that the deficiency is not easily detected by the usual blood tests. Therefore, individuals taking anticonvulsant drugs for several months or years might prevent nerve and mental problems by supplementing with vitamin B12.

Topiramate
Anemia is an uncommon side effect experienced by people taking anticonvulsant drugs. Though many researches believe that low blood levels of folic acid are involved, the effects might be caused by a vitamin B12 deficiency. Deficiencies of folic acid and vitamin B12 can lead to nerve and mental problems. One study revealed that individuals on long-term anticonvulsant therapy, despite having no laboratory signs of anemia, had dramatically lower levels of vitamin B12 in their cerebrospinal fluid (the fluid that bathes the brain) when compared with people who were not taking seizure medications. Improvement in mental status and nerve function was observed in a majority of symptomatic individuals after taking 30 mcg of vitamin B12 daily for a few days. Another study found that long-term anticonvulsant therapy had no effect on blood levels of vitamin B12. The results of these two studies indicate that people taking anticonvulsant drugs might experience side effects of vitamin B12 deficiency, and that the deficiency is not easily detected by the usual blood tests. Therefore, individuals taking anticonvulsant drugs for several months or years might prevent nerve and mental problems by supplementing with vitamin B12.

The results of these two studies indicate that people taking anticonvulsant drugs might experience side effects of vitamin B12 deficiency, and that the deficiency is not easily detected by the usual blood tests. Therefore, individuals taking anticonvulsant drugs for several months or years might prevent nerve and mental problems by supplementing with vitamin B12.
