7. Precautions and Warnings

Allergic Reactions

It is important to note that some individuals may be allergic to Cephalexin or other cephalosporin antibiotics. If you have a known allergy to cephalosporins or have had an allergic reaction to any other medication in the past, make sure to inform your healthcare provider before starting Keftab. Allergic reactions to Cephalexin can range from mild skin rashes to severe and life-threatening anaphylaxis. If you experience any signs of an allergic reaction such as swelling, itching, difficulty breathing, or hives, seek medical attention immediately.

Pregnancy and Breastfeeding

It is advisable to discuss the potential risks and benefits of using Keftab with your healthcare provider if you are pregnant or planning to become pregnant. While there is limited data available on the use of Cephalexin during pregnancy, some studies have shown potential harm to the fetus in animal models. However, the decision to use Keftab during pregnancy should be based on careful consideration of the potential benefits and risks.

Cephalexin can pass into breast milk and may cause harm to a nursing infant. Therefore, it is generally recommended to avoid using Keftab while breastfeeding. If the use of Keftab is deemed necessary, your healthcare provider may advise discontinuing breastfeeding for the duration of the treatment.

Kidney Function

Patients with impaired kidney function require dosage adjustments when taking Keftab. The drug is primarily eliminated through the kidneys, and a reduction in dosage or extended dosing intervals may be required for individuals with renal impairment. It is essential to inform your healthcare provider about any pre-existing kidney conditions or if you are taking any other medications that may affect kidney function. Close monitoring of kidney function and regular follow-ups with your healthcare provider are important to ensure the safe and effective use of Keftab in these patients.

Drug Interactions

Keftab may interact with other medications, resulting in reduced effectiveness or increased side effects. It is vital to inform your healthcare provider and pharmacist about all the medications you are currently taking, including prescription drugs, over-the-counter medicines, herbal supplements, and vitamins. Certain drugs, such as probenecid, may increase the levels of Cephalexin in the blood, leading to a higher risk of side effects. On the other hand, medications like oral contraceptives may be less effective when used concomitantly with Keftab. Your healthcare provider will assess the potential drug interactions and adjust the dosage or provide suitable alternatives if necessary.

Safety in Pediatric Patients

Keftab is generally considered safe for use in children, but dosage adjustments may be required based on the child’s weight and age. It is important to follow the dosage instructions provided by your healthcare provider and report any unusual side effects to your child’s doctor.

Monitoring and Follow-up

Regular monitoring of kidney function, blood counts, and liver function is necessary while taking Keftab for an extended period. Your healthcare provider may order laboratory tests and schedule follow-up appointments to ensure the medication is working effectively and not causing any harm. It is important to attend these appointments and report any concerns or side effects promptly.
