Cautions with other medicines
There are some medicines that can affect the way Gaviscon works.
Do not take Gaviscon within 2 hours before or after taking:
- antihistamines
- some antibiotics (quinolones and tetracyclines)
- iron tablets
- medicines to treat fungal infections
- beta blockers (for heart problems)
- penicillamine (for rheumatoid arthritis)
- steroids (for inflammatory and autoimmune disorders)
- antipsychotic medicines (for mental health problems like bipolar disorder and schizophrenia)
- chloroquine (for malaria)
- estramustine (for prostate cancer)
- bisphosphonates such as alendronic acid (to treat and prevent bone problems such as osteoporosis)
- levothyroxine
If you take Gaviscon, speak to a doctor or pharmacist before starting to take any of these medicines.
These are not all the medicines that may cause problems if you take them with Gaviscon. For a full list, see the leaflet inside your medicine packet.
Taking Gaviscon with painkillers
It's safe to take paracetamol at the same time as Gaviscon. But do not take other painkillers, like ibuprofen or aspirin, with Gaviscon without talking to your doctor or pharmacist first. These can make your symptoms worse.
