Selexid belongs to a group of medicines called penicillins. It is a type of antibiotic. Selexid works by killing the bacteria that cause infections.

Antibiotics are used to treat bacterial infections and are not effective against viral infections.

It is important that you follow the instructions regarding the dose, administration interval, and treatment duration indicated by your doctor.

Do not store or reuse this medicine. If you have any leftover antibiotic after finishing the treatment, return it to the pharmacy for proper disposal. Do not throw away medicines via wastewater or household waste.

Selexid is used to treat bladder infections (cystitis) in adults.

2. What you need to know before you take Selexid

Your doctor may have prescribed a different use or dose than what is indicated in this information. Follow your doctor's instructions exactly.

Do not take Selexid:

  • If you are allergic (hypersensitive) to pivmecillinam or any of the other ingredients of this medicine (listed in section 6).
  • If you are allergic (hypersensitive) to other antibiotics. These antibiotics include penicillins and cephalosporins.
  • If you have ever experienced a severe skin rash, skin peeling, blisters, and/or mouth ulcers after taking Selexid 400 mg film-coated tablets EFG or other beta-lactam antibiotics (such as amoxicillin, penicillin V, and flucloxacillin).
  • If you have a narrowing of the digestive tract.
  • If you have a disorder that can reduce the amount of a substance called carnitine in your body. These disorders include a carnitine transporter defect, methylmalonic aciduria, and propionic acidemia.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Selexid. The tablets should be taken with at least half a glass of liquid to avoid the tablets getting stuck in the digestive tract.

Before starting treatment, inform your doctor:

  • If you have porphyria.
  • If you have recently used Selexid, as prolonged use can reduce the amount of carnitine in your body.

During treatment:

  • Severe skin reactions (SSR), including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported in relation to treatment with Selexid 400 mg film-coated tablets EFG. Stop treatment with Selexid 400 mg film-coated tablets EFG and seek immediate medical attention if you experience any of the symptoms related to severe skin reactions described in section 4.
  • If you experience sudden diarrhea while taking Selexid, inform your doctor immediately. This may be due to inflammation of the intestine (colitis).
  • Taking pivmecillinam shortly before birth may affect the results of neonatal tests for detecting hereditary metabolic disorders and give a false positive result. A "false positive" means that the result incorrectly indicates that the baby has a disorder. There is no risk to the neonate, but you should inform your doctor that you have taken Selexid shortly before birth.

Children and adolescents

Do not give this medicine to children and adolescents under 18 years of age, as the potential benefits may not outweigh the risks.

Taking Selexid with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Inform your doctor or pharmacist if you are taking any of the following medicines:

  • Probenecid (for the treatment of gout). This may enhance the effect of Selexid.
  • Methotrexate (for the treatment of rheumatism and cancer). The excretion of methotrexate from your body may be slower if used with Selexid.
  • Valproate or valproic acid (for the treatment of epilepsy). This increases the risk of having too low a level of carnitine in your body if used with Selexid.
  • Other antibiotics (e.g., tetracyclines, erythromycin, other beta-lactam antibiotics).

This may affect the effect of Selexid.

Taking Selexid with food and drinks

You can take the medicine with or immediately after a meal. Selexid should be taken with at least half a glass of water. It is important that you take your medicine with plenty of liquid and a long time before going to bed. This will prevent digestive tract disorders.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Selexid can be used during pregnancy.

There have been reports of false positives in neonatal screening tests, where it has simulated the presence of isovaleric acidemia. Taking pivmecillinam shortly before birth may affect the results of neonatal tests for detecting hereditary metabolic disorders and give a false positive result. A "false positive" means that the result incorrectly indicates that the baby has a disorder. There is no risk to the neonate, but you should inform your doctor that you have taken Selexid shortly before birth.

Breastfeeding

Selexid can be used during breastfeeding.

Fertility

No clinical studies have been conducted regarding fertility.

Driving and using machines

The influence of Selexid on the ability to drive and use machines is negligible.
