According to the NHS, folic acid can also affect the way other medicines work.
“Do not take your folic acid within two hours before or after taking indigestion remedies (antacids containing aluminium or magnesium), as they may stop folic acid being properly absorbed,” warns the health body.
Tell your doctor if you’re taking these medicines before you start taking folic acid:
- Methotrexate, a medicine used to treat rheumatoid arthritis, Crohn’s disease, psoriasis and some types of cancer
- Phenytoin, fosphenytoin, phenobarbital or primidone, medicines used to treat epilepsy
- Fluorouracil, capecitabine, raltitrexed or tegafur, medicines used to treat some types of cancer
- Antibiotics, medicines used to treat or prevent bacterial infection
- Medicines or alternative remedies that contain zinc (including throat lozenges and cold remedies)
- Sulfasalazine, a medicine used to treat the inflammatory bowel conditions ulcerative colitis and Crohn’s disease
- Cholestyramine, a medicine used to reduce cholesterol.
