IV iron therapy is recommended if not receiving the necessary iron from blood transfusions but the dosing is unclear.Diuretics are generally not used because of the decrease in blood volume which can cause a person with SCD to have a sickle cell crisis but it can help treat circulatory overload; a condition caused from blood transfusions where there is too much fluid in the circulatory system. Loop diuretics (furosemide) have also been used in treating severe hematuria by increasing urine flow. == References ==
This is consistent with the observation that animal screening models indicate putative antidepressant activity for this compound, although one study has been negative. Formal clinical trials in depressed patients have not been reported.It has also been investigated for use in the treatment of cancer. Captopril stereoisomers were also reported to inhibit some metallo-β-lactamases. Adverse effects
Adverse effects of captopril include cough due to increase in the plasma levels of bradykinin, angioedema, agranulocytosis, proteinuria, hyperkalemia, taste alteration, teratogenicity, postural hypotension, acute renal failure, and leukopenia. Except for postural hypotension, which occurs due to the short and fast mode of action of captopril, most of the side effects mentioned are common for all ACE inhibitors. Among these, cough is the most common adverse effect. Hyperkalemia can occur, especially if used with other drugs which elevate potassium level in blood, such as potassium-sparing diuretics. Other side effects are:

Itching
Headache
Tachycardia
Chest pain
Palpitations
Dysgeusia
WeaknessThe adverse drug reaction (ADR) profile of captopril is similar to other ACE inhibitors, with cough being the most common ADR. However, captopril is also commonly associated with rash and taste disturbances (metallic or loss of taste), which are attributed to the unique thiol moiety. Overdose
ACE inhibitor overdose can be treated with naloxone. History
In the late 1960s, John Vane of the Royal College of Surgeons of England was working on mechanisms by which the body regulates blood pressure. He was joined by Sérgio Henrique Ferreira of Brazil, who had been studying the venom of a Brazilian pit viper, the jararaca (Bothrops jararaca), and brought a sample of the vipers venom.
