CEPHALEXIN antibiotic education | Uses, doses, side effects and more

In this video, I’m going to cover essential insights about Cefalexin, a medication that plays a crucial role in treating various infections. Whether you’re dealing with a urinary tract infection (UTI), pneumonia, or certain skin infections, understanding how Cefalexin works and its potential side effects is vital for your health and well-being.

Cefalexin, also known by its brand name Keflex, is an antibiotic that belongs to the cephalosporin class. These antibiotics work by disrupting the cell wall synthesis of bacteria, effectively stopping their growth and helping your body to fight off the infection. In the UK, Cefalexin is available only by prescription and comes in various forms, including capsules, tablets, and liquid.

When it comes to who can take Cefalexin, most adults and children can safely use it. However, it’s essential to consult your doctor if you have a history of allergic reactions to Cefalexin or any other medications, kidney problems, or if you’ve experienced severe skin reactions or gastrointestinal issues after taking antibiotics in the past. This ensures that Cefalexin is safe for you or your child.

Now, let’s discuss how and when to take Cefalexin. Always follow your doctor’s instructions regarding dosage. For most infections, adults typically take 500 mg two to three times a day. However, your doctor may adjust this based on the severity of your infection. If you’re taking capsules or tablets, swallow them whole with a glass of water—do not chew or break them. If you’re using the liquid form, it’s usually prepared by a pharmacist, and you should use a proper measuring device to ensure you’re taking the correct dose.

It’s important to space your doses evenly throughout the day. For example, if you’re taking it three times a day, you might take it in the morning, mid-afternoon, and just before bedtime. The duration of treatment will depend on the type of infection, but it’s crucial to complete the full course as prescribed, even if you start feeling better. Stopping early can lead to antibiotic resistance, a significant public health concern.

If you forget a dose, take it as soon as you remember unless it’s almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Never take two doses at once to make up for a forgotten one.

Like all medications, Cefalexin can cause side effects. Many people experience no side effects or only mild ones. Common side effects include nausea, diarrhea, and mild stomach discomfort, which usually resolve within a couple of days. If these side effects persist or worsen, consult your doctor or pharmacist.

Serious side effects are rare but can occur. If you experience severe diarrhea, especially if it contains blood or mucus, or if you notice yellowing of your skin or eyes, seek medical attention immediately. These could be signs of liver problems or other serious conditions. Anaphylaxis, a severe allergic reaction, is also a possibility, though rare. If you experience swelling of the face, tongue, or lips, seek emergency help right away.

For those who are pregnant or breastfeeding, Cefalexin is generally considered safe. There’s no evidence to suggest it harms the baby during pregnancy, and only small amounts pass into breast milk. However, it’s crucial to treat infections during these times to avoid complications. There’s also no evidence that Cefalexin affects fertility in either men or women.

If you’re taking other medications or supplements, it’s essential to inform your doctor or pharmacist. Certain medications, such as those for gout or diabetes, and diuretics can interact with Cefalexin. Additionally, avoid taking Cefalexin with zinc supplements, as zinc can reduce the effectiveness of the antibiotic.

A common question I often receive is whether it’s safe to drink alcohol while taking Cefalexin. The answer is yes; moderate alcohol consumption is generally acceptable. There are no specific foods or drinks you need to avoid while on this medication, so you can maintain your regular diet.

In summary, Cefalexin is a valuable antibiotic for treating various infections, but it’s essential to use it responsibly. Always follow your healthcare provider’s instructions, complete your course of treatment, and communicate any concerns or side effects you may experience.
