1. What is Adnamil and what is it used for

Allopurinol, the active substance of Adnamil, and its main metabolite oxypurinol, reduce the concentration of uric acid in serum and urine by inhibiting the activity of xanthine oxidase, an enzyme that catalyzes the oxidation of hypoxanthine to xanthine and xanthine to uric acid.
Taking Adnamil is indicated to reduce the production of uric acid in diseases where its deposition has already occurred (e.g., gouty arthritis, gouty tophi, kidney stones) or in clinical conditions where there is such a risk (e.g., cancer treatment potentially leading to acute uric acid nephropathy).
The main clinical conditions where uric acid deposition may occur are:

• primary gout
• uric acid stones
• acute uric acid nephropathy
• cancer and myeloproliferative disorders with rapid cell turnover, where increased uric acid levels occur spontaneously or are induced by cytotoxic treatment
• disorders of certain enzyme functions, leading to overproduction of uric acid, e.g.:
• hypoxanthine-guanine phosphoribosyltransferase (e.g., Lesch-Nyhan syndrome);
• glucose-6-phosphatase (e.g., glycogen storage disease);
• phosphoribosylpyrophosphate synthetase;
• phosphoribosylpyrophosphate amidotransferase;
• adenine phosphoribosyltransferase.

Adnamil is indicated for the treatment of kidney stones with 2,8-dihydroxyadenine (2,8-DHA) stones, resulting from decreased activity of adenine phosphoribosyltransferase.
Adnamil is indicated for the treatment of recurrent kidney stones, with mixed calcium oxalate stones, with accompanying hyperuricosuria, in cases where dietary, fluid, and other treatments have been ineffective.

2. Important information before taking Adnamil

When not to take Adnamil

• if you are allergic to allopurinol or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Before starting to take Adnamil, discuss it with your doctor or pharmacist if you:

• are of Chinese, African, or Indian origin;
• have liver or kidney problems. Your doctor may use a lower dose or recommend taking the medicine less often than once a day. They will also closely monitor your condition;
• have heart problems or high blood pressure and are taking diuretics and/or ACE inhibitors;
• are currently having a gout attack;
• have thyroid problems.

If you are unsure whether any of the above applies to you, consult your doctor or pharmacist before taking allopurinol.

Special precautions while taking Adnamil

During treatment with allopurinol, severe skin reactions have been reported, including hypersensitivity syndrome, Stevens-Johnson syndrome, and toxic epidermal necrolysis.
Often, the rash can involve ulcers of the mouth, throat, nose, genitals, and conjunctivitis (red and swollen eyes). Such severe skin reactions are often preceded by symptoms similar to the flu, such as fever, headache, body aches (so-called flu-like symptoms). The rash may progress, leading to the formation of blisters and peeling of the skin. Such severe skin reactions may occur more frequently in people of Chinese (Han ethnic group), Thai, or Korean origin. Chronic kidney disease may also increase the risk in these patients.
If a rash or skin symptoms occur, stop taking allopurinol immediately and contact your doctor.
In cancer or Lesch-Nyhan syndrome, the amount of uric acid in the urine may increase. To prevent this, ensure adequate hydration of the patient to dilute the urine.
If you have kidney stones, they may decrease in size and enter the urinary tract.

Children

Taking Adnamil in children is rarely indicated, except for certain types of cancer (especially leukemia) and certain enzymatic disorders, such as Lesch-Nyhan syndrome.

Adnamil and other medicines

Tell your doctor or pharmacist about all medicines you are taking now or have recently taken, as well as any medicines you plan to take. This includes medicines available without a prescription, including herbal medicines. This is because Adnamil may affect the way some medicines work. Also, some other medicines may affect the way Adnamil works.
Tell your doctor or pharmacist if you are taking any of the following medicines:

• salicylates, including acetylsalicylic acid;
• theophylline, used for breathing problems;
• medicines used to treat seizures (epilepsy), phenytoin;
• vidarabine, used to treat viral infections;
• antibiotics (ampicillin, amoxicillin);
• didanosine, used to treat HIV infection;
• medicines used to treat cancer;
• medicines used to weaken the immune response (immunosuppressants), such as 6-mercaptopurine, azathioprine, and cyclosporine;
• chlorpropamide (a medicine used to treat diabetes);
• medicines used to treat heart problems or high blood pressure, such as ACE inhibitors or diuretics;
• medicines used to thin the blood (anticoagulants), such as warfarin;
• other medicines used to treat gout.

If you are taking aluminum hydroxide, allopurinol may have a reduced effect.
Keep a gap of at least 3 hours between taking both medicines.
Blood disorders occur more frequently when allopurinol is taken with cytostatics (e.g., cyclophosphamide, doxorubicin, bleomycin, procarbazine, alkyl halides) than when these active substances are taken alone. Therefore, regular blood morphology tests should be performed.

Allopurinol passes into breast milk. It is not recommended to take this medicine during breastfeeding.
