Cloxacillin
About Cloxacillin
Cloxacillin is an antibiotic prescribed to treat a variety of bacterial infections, particularly those affecting the skin, respiratory tract, and bones. It works by targeting and destroying the specific bacteria causing the infection, helping your body recover completely. Your doctor will determine the right length of treatment based on the severity of your infection.
To get the best results, you must take this medicine consistently and at evenly spaced intervals throughout the day. It is highly recommended to take this medication on an empty stomach, either one hour before or two hours after a meal, as food can interfere with how well your body absorbs it. Staying well-hydrated and resting during your treatment also supports a faster recovery.
While taking Cloxacillin, some people may experience mild side effects like an upset stomach, nausea, or mild diarrhoea. Most of these symptoms are temporary, but you should contact your doctor immediately if you develop severe watery diarrhoea, a skin rash, or difficulty breathing.
Before starting this medicine, tell your doctor if you have a history of kidney disease or asthma. Do not take this if you have ever had a severe allergic reaction to penicillin or similar antibiotic medications, as this can lead to a dangerous reaction.
This medicine may interact with certain medicines, such as blood thinners and methotrexate. Current evidence does not support a clinically meaningful interaction between cloxacillin and combined oral contraceptives. If you have concerns about contraception while taking antibiotics, discuss them with your doctor or pharmacist. It is also wise to avoid alcohol during treatment to prevent worsening stomach upset, and if you are pregnant, breastfeeding, or an older adult, you should consult your doctor before starting therapy.

Medicines Containing this Salt
View AllDrug Warnings
- Do not stop taking this medicine early, even if you feel completely better, to prevent the infection from returning or becoming drug-resistant.
- Never share your medication with another person, even if they appear to have the exact same symptoms.
- Always inspect the packaging before use; do not take the medication if the seal is broken or if the capsules appear damaged.
- If using the liquid suspension form, always shake the bottle well before measuring each dose, and use the official oral syringe or measuring cup provided.
- Contact your doctor immediately if you develop a new fever, joint pain, or skin rash during your treatment course, as these can be delayed signs of an allergic reaction.
Drug Interactions
- Combined oral contraceptives: Current evidence does not indicate a clinically meaningful pharmacokinetic interaction between cloxacillin and combined oral contraceptives. Additional contraceptive precautions are not routinely required solely because of cloxacillin use. However, if vomiting or severe diarrhoea occurs, contraceptive effectiveness may be reduced because pill absorption can be affected. Consult your doctor if you are concerned.
- Methotrexate: May increase the risk of serious side effects by slowing down how quickly your body clears methotrexate.
- Blood thinners (like warfarin): May increase the risk of bleeding; your doctor may need to monitor your blood clotting tests more closely.
- Probenecid: May increase the levels of Cloxacillin in your blood by slowing its elimination through the kidneys, which can raise your risk of side effects.

Habit Forming
Diet & Lifestyle Advise
- Maintain a strict empty-stomach schedule: Always take this medicine 1 hour before or 2 hours after your meals, as food significantly blocks its absorption.
- Stay fully hydrated: Drink plenty of water throughout the day to help your kidneys filter and eliminate the medication safely.
- Support your gut health: Consider eating probiotic-rich foods (like yoghurt) or taking a probiotic supplement at least 2 hours before or after your antibiotic dose to help protect your gut microbiome.
- Keep the infection site clean: If you are treating a skin infection, wash the area gently with mild soap, keep it dry, and keep it covered as directed to prevent bacteria from spreading.

Current evidence does not show that cloxacillin meaningfully reduces the effectiveness of combined oral contraceptive pills. However, if you experience vomiting or severe diarrhoea while taking this medicine, your contraceptive pill may not be absorbed properly, which could reduce its effectiveness. Follow the instructions in your contraceptive's patient leaflet for missed pills due to vomiting or diarrhoea, and consult your doctor or pharmacist if you have any concerns.
Take the missed dose as soon as you remember, but skip it if it is almost time for your next regular dose. Do not take two doses at once to make up for a missed one. Talk to your doctor or pharmacist if you frequently forget your doses.
