Key points

  • Fludrocortisone, desmopressin, tolvaptan and testosterone are not interchangeable forms of hormone replacement.
  • Fluid balance, blood pressure, electrolytes, liver function or hormone levels may need monitoring, depending on treatment.
  • Severe weakness, confusion, collapse, repeated vomiting or a major change in thirst or urination require urgent assessment.

Select a listed product and pack to order online. Supply depends on stock and destination rules; ask your doctor or pharmacist whether it suits you.

How the medicine groups differ

  • Adrenal replacement: fludrocortisone replaces mineralocorticoid activity in selected adrenal disorders.
  • Fluid-balance medicines: desmopressin acts like vasopressin, while tolvaptan blocks vasopressin receptors. They have opposite effects in different conditions.
  • Androgen replacement: testosterone may be used only after compatible symptoms and low levels have been clinically assessed.

What these medicines are used for

Linked conditions include adrenal insufficiency and diabetes insipidus, alongside other diagnosed endocrine or fluid-balance disorders. These replace or mimic a hormone the body is not producing in the right amount, so dosing follows measured levels rather than symptoms alone. With several of them, stopping abruptly is more dangerous than the condition being treated.

Important safety checks

Electrolytes, fluid intake, blood pressure, liver or kidney health, pregnancy and interacting medicines can affect safety. Do not adjust fluid intake or stop adrenal replacement based only on catalogue information; follow the treating team’s sick-day and monitoring plan.

When to seek urgent care

Seek urgent help for collapse, confusion, seizure, repeated vomiting, severe weakness, inability to keep replacement medicine down, or a sudden major change in thirst, urination or fluid balance.
