Warnings

  • Blood pressure lowering medicines such as Calchan Mr can occasionally make you feel dizzy or weary. If you are affected, you should take care when driving or operating machinery.
  • If you experience any chest pain after taking this medicine you should not take a further dose until you have consulted your doctor.
  • Calchan Mr should not be used to treat an attack of angina, as it won't work quickly enough.
  • There are several different brands of long-acting or slow-release nifedipine available in the UK. These can usually be identified because their names end in XL, MR, LA, SR and so on. The way that the nifedipine is released from different brands can vary and this means that different brands can have different clinical effects. For this reason, it is important that you always take the same brand of nifedipine. You should make sure you know which brand you take and check that you have been given the correct one each time your medicine is dispensed. (Your pharmacist will usually ask you, or call your doctor if this is not written on your prescription).
