Buy Phenoxymethylpenicillin (Pen V) 250mg Tablets For Sinusitis Online

When sinus pain strikes it can leave you feeling low. Your face throbs, your head aches and your nose feels stuffy, making it hard to concentrate on everyday tasks. If it’s viral it usually clears up on its own in a few days. But if your symptoms last for ten or more days without improvement it’s more likely to be bacterial sinusitis. This is when Phenoxymethylpenicillin (Pen V) can help.

It's the first-choice antibiotic treatment recommended by NICE to help relieve acute sinusitis and get you back to normal fast. So, if you’ve been suffering with sinusitis for a while now, it’s time to get in touch and speak to one of our healthcare professionals.

About Phenoxymethylpenicillin Tablets For Sinusitis

Phenoxymethylpenicillin (Pen V) is a penicillin-based antibiotic used to treat certain infections, including acute bacterial sinusitis. If you have a sinus infection which hasn’t cleared up after ten or more days, it could indicate it’s a bacterial rather than a viral infection, and our UK clinical team may prescribe Pen V to get rid of it.

It’s an effective antibiotic and considered the first-choice treatment for bacterial sinusitis, helping to reduce inflammation and ease symptoms like facial pain and congestion.

How Does Pen V Work?

Bacterial sinusitis occurs when bacteria infect your sinus cavities – the air-filled spaces behind your nose and face. This causes inflammation, congestion, pressure and pain in your head and face.

Pen V works by directly attacking these bacteria and supporting your immune system. It blocks their ability to produce strong cell walls which they need to survive. Without proper cell walls the bacteria weaken, break apart and die.

How To Take Phenoxymethylpenicillin For Sinusitis

NICE recommends you should take 500mg four times a day for five days on an empty stomach. This should be spaced evenly throughout the day, for example first thing in the morning, at midday, later afternoon and before bedtime.

Avoid taking Pen V at mealtimes because taking it with food can make it less effective. Instead, take it either 30 minutes before you eat or two hours after you’ve eaten.

Ingredients

The active ingredient in Pen V is phenoxymethylpenicillin. Each tablet contains 250mg phenoxymethylpenicillin as phenoxymethylpenicillin potassium.

The non-active ingredients are Calcium Hydrogen Phosphate Dihydrate, Maize Starch, Cellulose, Microcrystalline (E460), Magnesium Stearate (E572), Basic Butylated Methacrylate, Macrogol 6000, Sodium Lauryl Sulfate (E487), Stearic acid (E570) and Titanium Dioxide (E171).

The tablets contain 28mg potassium which may be harmful to people on low sodium diets or with reduced kidney function.

Side Effects

Like any medication, Pen V can cause side effects although not everyone will experience them. Common side effects include nausea, being sick, diarrhoea, thrush or inflammation of the vaginal area and soft stools. If you’re worried about anything related to your treatment, speak to our healthcare professionals.

However, if you experience severe diarrhoea, vomiting, signs of an allergic reaction such as difficulty breathing, swelling of the face, lips and throat, or unusual bleeding or bruising you should stop taking the medication and seek medical attention immediately.

Warnings

While Pen V is an effective antibiotic it’s not suitable for everyone. You should not take it if you’re allergic to penicillin or other antibiotics.

If you have kidney problems or other conditions which affect your metabolism it’s also not suitable. Some medications, such as methotrexate or blood thinners, may interact with Pen V and affect how it works. During your consultation, tell our healthcare professionals about any allergies, medical history, or other medicines you’re taking before starting treatment so we can ensure it’s safe for you.
