FAQ

A prescription is required to buy oral chloramphenicol from local pharmacies in the United Kingdom. Our store policy allows Chloromycetin 500 mg capsules to be ordered without a prescription and sent by mail. Because this antibiotic can cause serious adverse effects and requires appropriate monitoring, treatment should be discussed with a clinician.

Do not extend a chloramphenicol course without clinical review. Ongoing symptoms can mean that the infection needs reassessment, testing or a different treatment, while unnecessary prolonged use increases the risk of serious toxicity, including blood disorders.

Seek clinical reassessment rather than changing the dose or extending treatment yourself. Chloramphenicol is reserved for serious bacterial infections, so lack of improvement may require confirmation of the diagnosis, bacterial susceptibility or an alternative antibiotic.

The colour, size, capsule shell, markings and packaging may differ between products and manufacturers. These differences do not by themselves mean that a medicine is incorrect; confirm the active ingredient, 500 mg strength, oral capsule form, manufacturer and package details on receipt.

Store the capsules at 20°C to 25°C in a tightly closed, light-resistant container, protected from moisture. Keep them in their labelled packaging and out of the reach of children.

Chloromycetin contains chloramphenicol, an amphenicol antibiotic used for certain serious bacterial infections when safer antibiotics are ineffective or unsuitable. Established systemic uses include infections such as typhoid fever and cholera caused by susceptible bacteria. It is not appropriate for viral infections such as colds or flu.

Oral chloramphenicol should generally be avoided during pregnancy because it crosses the placenta and may cause fetal or neonatal toxicity, particularly near delivery. It should also be avoided while breastfeeding because it passes into breast milk and may cause serious adverse effects, including bone-marrow toxicity, in the infant.

These are oral capsules and should be swallowed whole with water, generally on an empty stomach unless a prescriber gives different instructions. The dose, dosing interval and treatment duration depend on the infection, age, body weight and kidney or liver function. Systemic chloramphenicol requires clinical supervision and blood-count monitoring because of the risk of severe blood disorders.

Description

Chloromycetin is a drug in the broad-spectrum antibiotic family. It reduces numerous bacterial infections, including those of the blood, brain, lung, and other major organs. However, it is ineffective for viral illnesses, colds, or the flu.

Even if you see improvements in your health, never stop taking Chloromycetin earlier than suggested by your doctor. If you stop taking the drug too soon, it could make things worse. Until you know how this drug affects you, take caution when operating machinery, driving, climbing, or performing other risky actions. Avoid consuming alcohol. Before giving this medicine to a child, always contact a doctor.

Consult a physician if any of the following apply to you or have previously affected you: cardiac conditions (such as irregular heart rhythms), kidney or liver disease, anemia or other blood conditions, allergy to chloramphenicol or related drugs, foods, coloring materials, or preservatives, digestive or intestine issues, particularly colitis, dental issues, pregnancy, nursing, or intending to get pregnant.

Chloromycetin250mg

Chloromycetin is available as a liquid solution and capsule for oral use.

This drug is often taken in 50 milligrams (mg). It is advised to take medication four times a day, on schedule.

Some fluids should accompany this medication. When using Chloromycetin, it is best to drink multiple glasses of water daily to protect your kidneys. You can take it on an empty stomach or with food. Taking the medication with food lessens gastrointestinal discomfort and facilitates your body's absorption of the medication.

It is recommended to swallow the capsules whole. Never open, chew, break, or crush them.

For the medicine to be evenly mixed, give the beverage a good shake before using it. Use a measuring spoon or medicine cup with a designated marking to ensure you are taking the right amount.

As directed by your doctor and on the label of your prescription, take this medication as directed.

Try to take the dose as soon as you remember if you miss it. Take just one dose if it's time for your next one. The dosage doesn't need to be doubled.

Any medication used in excess might have detrimental effects on your health. Consult your healthcare physician right away if you believe you have overdosed.

Talk to a doctor about using your medication with food, drink, or tobacco with your healthcare provider.

Customer questions

Asked by Aoife Martin, Lisburn, United Kingdom

I live in Lisburn, Northern Ireland. Can I check whether Chloromycetin can be delivered to my address before I pay?

Answered by Support team

Yes. Enter your delivery details at checkout to see the destination options available for your Lisburn address before completing payment. Availability is confirmed there rather than assumed for all Northern Ireland addresses.

Asked by Daniel Price, Birmingham, United Kingdom

Before ordering from Birmingham, can I use my postcode to check whether this medicine can be delivered to me?

Answered by Support team

Yes. Use your Birmingham postcode in the checkout delivery section to check the options shown for your address. This is the appropriate way to confirm destination availability before placing the order.

Asked by Hannah Wilson, Stoke-on-Trent, United Kingdom

My order to Stoke-on-Trent now says it has been dispatched. Does that mean it will arrive tomorrow?

Answered by Support team

Not necessarily. Dispatch means the order has been sent, while delivery is a separate step and an arrival date cannot be assumed from dispatch status alone.

Asked by Oliver Grant, Newcastle upon Tyne, United Kingdom

My parcel is later than expected and I need to know what happens next. What should I do?

Answered by Support team

Please contact our customer support team so we can check the parcel with the delivery service. If necessary, we can arrange a free replacement order or a refund.

Asked by Margaret Collins, London, United Kingdom

I take warfarin and have been advised to use Chloromycetin capsules. Can I take them together?

Answered by Support team
Medical reviewed by Mildred Torres

Chloramphenicol can slow the breakdown of warfarin and increase the risk of bleeding. The prescriber or anticoagulation clinic should review the combination and arrange any needed INR monitoring before treatment starts.
