Take special care with DYNAVAL CO:

  • Should you become pregnant while taking DYNAVAL CO, stop taking the tablets immediately and contact your doctor. A switch to a different treatment should be carried out before a planned pregnancy.
  • If you are on a low-salt diet, have lost a lot of fluids recently (due to excessive sweating, diarrhoea, vomiting, dialysis) or are taking high doses of water tablets.

  • If you have systemic lupus erythematosus (also called “lupus” or “SLE”). (Symptoms include pain in the joints or weakness in the muscles.)

The first dose may cause a bigger fall in blood pressure than the following doses.  You may notice this as a feeling of weakness or dizziness, and it may help to lie down.  Contact your doctor if you are worried.  In order to prevent an extreme fall in blood pressure with the first dose, existing therapy with diuretics (“water tablets”) should be discontinued 2 to 3 days before taking DYNAVAL CO.  Your doctor should check the electrolyte content of your blood thereafter.
