What it is and what it is used for

for The active ingredient in Sulfasalazine Suspension is sulfasalazine which is an antiinflammatory drug and belongs to a group of medicines called aminosalicylates. Your doctor may give you Sulfasalazine to treat and manage inflammatory bowel disease. Inflammatory bowel disease The main forms of inflammatory bowel disease are Ulcerative Colitis and Crohn's disease. Although the diseases have some features in common, there are some important differences.

  • Ulcerative Colitis is an inflammatory disease which affects only the large bowel (colon and back passage). The lining of the bowel becomes inflamed (red and swollen) and symptoms include abdominal pain and diarrhoea (which may contain blood and mucus). Sulfasalazine is used to control the flare-ups of ulcerative colitis. It may also be used at lower doses to prevent more flare-ups of ulcerative colitis.
  • Crohn's disease is an inflammatory disease which may affect any part of the digestive system from the mouth to the anus, but it most commonly affects the last part of the small bowel and the first part of the large bowel. Symptoms include abdominal pain and diarrhoea (which may be bloody). Sulfasalazine is used to control the flare-ups of Crohn's Disease.

You must talk to a doctor if you do not feel better or if you feel worse.

What you need to know before you take it

e Sulfasalazine Suspension Your doctor will perform complete blood counts and liver function tests before starting Sulfasalazine and every second week during the first three months of therapy. During the second three months, the same tests should be done once monthly and thereafter once every three months and as clinically indicated. Urine analysis and an assessment of kidney function should also be done in all patients initiating treatment with Sulfasalazine. For patients with baseline renal impairment, treatment with Sulfasalazine should only be initiated if the benefits are considered to outweigh risk. Thereafter, periodic renal function monitoring, especially in the early months of treatment, should be conducted by your doctor during treatment with Sulfasalazine. Treatment should be discontinued if renal function deteriorates. Do not take Sulfasalazine:

  • if you are allergic (hypersensitive) to any of the ingredients of Sulfasalazine Suspension
  • if you are allergic (hypersensitive) to salicylates (e.g. aspirin) or sulfonamides (e.g. a certain type of antibiotic)
  • if you have a disease known as porphyria (a rare blood pigment disorder). Your doctor will have already told you if you have this disease. Sulfasalazine should not be used in children under 2 years of age. Warnings and precautions Tell your doctor if you are taking or have recently taken Sulfasalazine, or any other sulfasalazine containing products, because they may affect results of blood and urine tests. Talk to your doctor or pharmacist before taking Sulfasalazine: • •

• • •

if you have ever had any problems with your liver or kidneys if you have been told by your doctor that you have an inherited condition in which the body doesn't have enough of an enzyme known as glucose-6-dehydrogenase which helps red blood cells function normally if you have ever had asthma if you are a child and have arthritis if you have a history of recurring chronic infections or an underlying condition which may predispose you to infections.

Oral sulfasalazine inhibits the absorption and metabolism of folic acid and may cause folic acid deficiency potentially resulting in serious blood disorders (e.g., red blood cells that are larger than normal and lower-than-normal number of red and white blood cells and platelets in the blood), this can be normalised by administration of folic acid or folinic acid (leucovorin). Because sulfasalazine causes crystalluria and kidney stone formation, adequate fluid intake should be ensured during treatment.

Potentially life-threatening skin rashes (exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis) have been reported with the use of Sulfasalazine, appearing initially as reddish target-like spots or circular patches often with central blisters on the trunk. Additional signs to look for include ulcers in the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes). These potentially life-threatening skin rashes are often accompanied by flu-like symptoms. The rash may progress to widespread blistering or peeling of the skin. The highest risk for occurrence of serious skin reactions is within the first weeks of treatment. If you have developed exfoliative dermatitis, Stevens-Johnson syndrome or toxic epidermal necrolysis with the use of Sulfasalazine you must not be re-started on Sulfasalazine at any time. If you develop a rash or these skin symptoms, stop taking Sulfasalazine, seek immediate advice from a doctor and tell your doctor that you are taking this medicine. Severe, life-threatening allergic reactions such as Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) have been reported in patients taking various drugs including Sulfasalazine. It is important to note that early signs of severe allergy, such as fever or swollen lymph nodes, may be present even though rash is not evident. If such signs or symptoms are present, you should seek immediate advice from a doctor. Sulfasalazine should be discontinued if an alternative cause for the signs or symptoms cannot be established. Children and adolescents Sulfasalazine is not recommended if you are a child and have systemic-onset juvenile rheumatoid arthritis (Stills disease). Tests on your blood, kidneys, liver and urine Your doctor will be taking blood tests to check your blood, your kidneys before you start treatment and regularly during treatment. They will also measure substances produced by your liver known as enzymes (liver function tests) before you start treatment and at regular intervals. They may also test your urine for protein and blood. Other medicines and Sulfasalazine Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. In particular, the following medicines may interact with Sulfasalazine:

  • any medicine for high blood sugar/diabetes
  • methenamine, an antibiotic for treating urinary tract infections
  • digoxin, used to treat heart failure
  • folate, sometimes taken during the first few weeks of pregnancy to reduce the risk of birth defects of the brain, spine or spinal cord, e.g. Spina Bifida
  • azathioprine and mercaptopurine, drugs used to help to suppress your body's immune response in organ transplantation and certain chronic inflammations (e.g. rheumatoid arthritis)
  • methotrexate, used to treat rheumatoid arthritis. Sulfasalazine Suspension with food and drink Sulfasalazine Suspension should be taken with or after food.

Pregnancy, breast-feeding and fertility If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby you MUST ask your doctor or pharmacist for advice before taking this medicine. You should avoid breast-feeding while taking this medicine. There have been reports of diarrhoea or blood in the stools of babies of breast-feeding mothers taking sulfasalazine. If this happens you must stop taking Sulfasalazine and see your doctor as soon as possible. There have been reports of babies with birth defects of the brain, spine or spinal cord born to mothers who were exposed to sulfasalazine during pregnancy, although the role of sulfasalazine in these defects has not been established. Low sperm count and infertility may occur in men treated with sulfasalazine. Discontinuation of the medicine appears to reverse these effects within 2 to 3 months. Ask your doctor or pharmacist for advice before taking any medicine. Driving and using machines Sulfasalazine is unlikely to affect your ability to drive or use machines. Sulfasalazine Suspension contains: –

This medicine contains 5 mg sodium benzoate in each 5ml. This medicine contains less than 1 mmol sodium (23 mg) per 5ml, that is to say essentially 'sodium-free'.

How to take it

Sulfasalazine Suspension The suspension should be taken with food. The doses should be evenly divided during the day. Unless your doctor has told you otherwise, the usual doses for the following conditions are: Ulcerative Colitis and Crohn's Disease Adults and the Elderly Severe flare-ups: 20-40 ml four times a day, with other medicines such as steroids. Do not leave more than 8 hours between the evening and the following morning dose. Mild/Moderate flare-ups: 20-40 ml four times a day, but not always with other medicines Ulcerative Colitis Maintenance: Once the flare-up is controlled the dose is slowly reduced to 40 ml each day. Your doctor will tell you how to reduce your dose. This lower dose may be continued for some time to help stop other flare-ups. Children 2 years of age and over Your doctor will tell you what dose your child will need to use. This will be based on your child's weight. How long should you use Sulfasalazine?

This depends on how well the suspension suits you. The suspension starts to work in a few days. If it works well, you may be using it for some time. Do not stop using the suspension just because you feel better without first talking to your doctor. Ensure that you drink adequate fluids whilst you are taking this medicine. This is to avoid problems with your kidneys. If you take more Sulfasalazine than you should Contact your nearest hospital casualty department or tell your doctor immediately, if you have taken too much suspension or if a child has taken your medicine. Please take this leaflet and the suspension with you to the hospital casualty department or to your doctor. If you forget to take Sulfasalazine If you forget to take a dose, take the next dose as usual. Do not take a double dose to make up for a missed one. 4. Possible side effects Like all medicines, Sulfasalazine can cause side effects, although not everybody gets them. Stop taking Sulfasalazine and tell your doctor immediately if you experience any of the following symptoms after taking this medicine. • •

• •

An allergic reaction such as sudden wheeziness, difficulty in breathing, swelling of eyelids, face or lips, rash or itching (especially affecting the whole body). If you develop a severe skin rash that causes blistering, (this can affect the mouth and tongue).

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Induction and maintenance of remission of ulcerative colitis and treatment of active Crohn's disease.

4.2. Posology and method of administration

The dose is adjusted according to the severity of the disease and the patient's tolerance of the drug, as detailed below.

A) Ulcerative Colitis

Adults and the Elderly

Severe attacks: 20 to 40 ml four times a day may be given in conjunction with steroids as part of an intensive management regime. Rapid passage of the suspension may reduce the effect of the drug.

The night time interval between doses should not exceed 8 hours.

Moderate attacks: 20 ml four times a day may be taken with or without steroids.

Maintenance therapy: With induction of remission, reduce the dose gradually to 40 ml per day. This dosage should be continued indefinitely, since discontinuance even several years after an acute attack is associated with a four-fold increase in relapse.

Children

The dose is reduced in proportion to body weight.

Acute attack or relapse: 0.8 - 1.2 ml/kg/day.

Maintenance dosage: 0.4 - 0.6 ml/kg/day.

B) Crohn's Disease

In active Crohn's Disease, sulfasalazine should be administered as in attacks of ulcerative colitis (see above).

4.3. Contraindications

Sulfasalazine is contraindicated in:

▪ Infants under the age of two years.

▪ Patients with a known hypersensitivity to sulfasalazine, its metabolites or any of the excipients as well as sulfonamides, salicylates or the sodium benzoate preservative.

▪ Patients with porphyria.

4.4. Special warnings and precautions for use

Serious infections associated with myelosuppression, including sepsis and pneumonia, have been reported. Patients who develop a new infection while undergoing treatment with sulfasalazine should be monitored closely. Administration of sulfasalazine should be discontinued if a patient develops a serious infection. Caution should be exercised when considering the use of sulfasalazine in patients with a history of recurring or chronic infections or with underlying conditions which may predispose patients to infections.

Complete blood counts, including differential white cell count and liver function tests, should be performed before starting sulfasalazine, and every second week during the first three months of therapy. During the second three months, the same tests should be done once monthly and thereafter once every three months, and as clinically indicated.

Baseline assessment of renal function (including urinalysis) is required to be performed in all patients initiating treatment with sulfasalazine. For patients with baseline renal impairment, treatment with sulfasalazine should only be initiated if the benefits are considered to outweigh risk. Thereafter, periodic renal function monitoring, especially in the early months of treatment, should be conducted based on clinical judgment taking baseline renal function into account. Treatment should be discontinued if renal function deteriorates.

The patient should also be counselled to report immediately with any sore throat, fever, malaise, pallor, purpura, jaundice or unexpected non-specific illness during sulfasalazine treatment, this may indicate myelosuppression, haemolysis or hepatoxicity. Treatment should be stopped immediately while awaiting the results of blood tests. Please see Section 4.4 “Interference with laboratory testing”.

Sulfasalazine should not be given to patients with impaired hepatic or renal function or with blood dyscrasias, unless the potential benefit outweighs the risk.

Sulfasalazine should be given with caution to patients with severe allergy or bronchial asthma.

Severe hypersensitivity reactions may include internal organ involvement, such as hepatitis, nephritis, myocarditis, mononucleosis-like syndrome (i.e., pseudomononucleosis), hematological abnormalities (including hematophagic histiocytosis), and/or pneumonitis including eosinophilic infiltration.

Use in children with the concomitant condition systemic onset juvenile rheumatoid arthritis may result in a serum sickness like reaction; therefore sulfasalazine is not recommended in these patients.

Since sulfasalazine may cause haemolytic anaemia, it should be used with caution in patients with glucose-6-phosphate dehydrogenase deficiency.

Oral sulfasalazine inhibits the absorption and metabolism of folic acid and may cause folic acid deficiency (see section 4.6) potentially resulting in serious blood disorders (e.g. macrocytosis and pancytopenia), this can be normalised by administration of folic acid or folinic acid (leucovorin).

Because sulfasalazine causes crystalluria and kidney stone formation, adequate fluid intake should be ensured during treatment.

Oligospermia and infertility may occur in men treated with sulfasalazine. Discontinuation of the drug appears to reverse these effects within 2 to 3 months.

Serious skin reactions, some of them fatal, including exfoliative dermatitis, Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported very rarely in association with the use of sulfasalazine. Patients should be advised of the signs and symptoms and monitored closely for skin reactions. The highest risk for occurrence of SJS or TEN is within the first month of treatment. Sulfasalazine should be discontinued at the first appearance of skin rash, mucosal lesions or any other sign of hypersensitivity. Severe, life-threatening, systemic hypersensitivity reactions such as Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) have been reported in patients taking various drugs including sulfasalazine. It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident. If such signs or symptoms are present, the patient should be evaluated immediately. Sulfasalazine should be discontinued if an alternative aetiology for the signs or symptoms cannot be established. The best results in managing SJS and TEN come from early diagnosis and immediate discontinuation of any suspect drug. Early withdrawal is associated with a better prognosis. If the patient has developed SJS or TEN with the use of sulfasalazine, sulfasalazine must not be re-started in this patient at any time.

Sulfasalazine may colour the urine orange-yellow.

Interference with laboratory testing

Several reports of possible interference with measurements, by liquid chromatography, of urinary normetanephrine causing a false-positive test result have been observed in patients exposed to sulfasalazine or its metabolite, mesalamine/mesalazine.

Sulfasalazine or its metabolites may interfere with ultraviolet absorbance, particularly at 340 nm, and may cause interference with some laboratory assays that use NAD(H) or NADP(H) to measure ultraviolet absorbance around that wavelength. Examples of such assays may include urea, ammonia, LDH, α-HBDH and glucose. It is possible that alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase-muscle/brain (CK-MB), glutamate dehydrogenase (GLDH), or thyroxine may also show interference when sulfasalazine treatment is given at high doses. Consult with the testing laboratory regarding the methodology used. Caution should be exercised in the interpretation of these laboratory results in patients who are receiving sulfasalazine. Results should be interpreted in conjunction with clinical findings.

Excipient warnings

- This medicine contains 5 mg sodium benzoate in each 5ml.

- This medicine contains less than 1 mmol sodium (23 mg) per 5ml, that is to say essentially 'sodium-free'.

4.5. Interaction with other medicinal products and other forms of interaction

Certain types of extended wear soft contact lenses may be permanently stained during therapy.

Reduced absorption of digoxin, resulting in non-therapeutic serum levels, has been reported when used concomitantly with oral sulfasalazine.

Sulfonamides bear certain chemical similarities to some oral hypoglycemic agents. Hypoglycemia has occurred in patients receiving sulfonamides. Patients receiving sulfasalazine and hypoglycemic agents should be closely monitored.

Due to inhibition of thiopurine methyltransferase by sulfasalazine, bone marrow suppression and leucopenia have been reported when the thiopurine 6-mercaptopurine or its prodrug, azathioprine, and oral sulfasalazine were used concomitantly.

Co-administration of oral sulfasalazine and methotrexate to rheumatoid arthritis patients did not alter the pharmacokinetic disposition of the drugs. However, an increased incidence of gastrointestinal adverse events, especially nausea, was reported.

4.6. Fertility, pregnancy and lactation

Pregnancy

Reproduction studies in rats and rabbits have revealed no evidence of harm to the foetus. Oral sulfasalazine inhibits the absorption and metabolism of folic acid and may cause folic acid deficiency. There have been reports of babies with neural tube defects born to mothers who were exposed to sulfasalazine during pregnancy, although the role of sulfasalazine in these defects has not been established. Because the possibility of harm cannot be completely ruled out, sulfasalazine should be used during pregnancy only if clearly needed.

Lactation

Sulfasalazine and sulfapyridine are found in low levels in breast milk. Patients should avoid breastfeeding while taking this medicine. There have been reports of bloody stools of diarrhoea in infants who were breastfeeding from mothers on sulfasalazine. In cases where the outcome was reported, bloody stools or diarrhoea resolved in the infant after discontinuation of sulfasalazine in the mother.

4.7. Effects on ability to drive and use machines

No specific effects.

4.8. Undesirable effects

Overall, about 75% of ADRs occur within three months of treatment and over 90% by six months. Some unwanted effects are dose-dependent and symptoms can often be alleviated by reduction of the dose.

General

Sulfasalazine is split by intestinal bacteria to sulfapyridine and 5-amino salicylate so ADRs to either sulfonamide or salicylate are possible. Patients with slow acetylator status are more likely to experience ADRs related to sulfapyridine. The most commonly encountered ADRs are nausea, headache, rash, loss of appetite and raised temperature.

Specific

The adverse reactions observed during clinical studies conducted with Sulfasalazine have been provided in a single list below by class and frequency (very common (≥1/10); common (≥1/100 to< 1/10); uncommon (≥1/1000 to < 1/100); rare (≥1/10,000 to <1/1000); very rare (<1/10,000); not known (cannot be estimated from available data)).
