Can augmentin (amoxicillin and clavulanate) cause rashes and if so how long will they last after stopping the antibiotic?

Yes. Up to 2 weeks.: Augmentin (amoxicillin and clavulanate) is Amoxicillin augmented with clavulanic acid. It enables Augmentin (amoxicillin and clavulanate) to kill bacteria resistant to amoxicillin. Like Amoxicillin Augmentin (amoxicillin and clavulanate) can cause an allergic rash - hives and angioedema usually appearing right after the 1st dose - or an Amoxicillin rash - red flat or raised spots that don't itch appearing on the 7-10th day of treatment. Once drug is stopped each rash is gone in 2 weeks. ...Read more

Is it normal for an itchy rash from augmentin (amoxicillin and clavulanate) to persist after being treated with 5 days of prednisone? This is day 5 after stopping pred, still spread

Is it normal for an itchy rash from augmentin (amoxicillin and clavulanate) to persist after being treated with 5 days of prednisone? This is day 5 after stopping pred, still spread

It can: It really depends on the mechanism causing the rash, the amount of augmentin (amoxicillin and clavulanate) taken before the rash developed, whether you are still taking the augmentin (amoxicillin and clavulanate), and of course, whether the augmentin (amoxicillin and clavulanate) was really the cause of the rash in the first place. One would need to consider a more prolonged prednisone taper or revisiting the original diagnosis. An Allergist can help ...Read more

I accidently took a double dose of Augmentin (amoxicillin and clavulanate) this morning. I got a rash from it. Should I hold off on taking it again tonight?

I accidently took a double dose of Augmentin (amoxicillin and clavulanate) this morning. I got a rash from it. Should I hold off on taking it again tonight?

Allergic rash: A double dose of Augmentin (amoxicillin and clavulanate) isn't harmful if not repeated several times. The higher dose probably isn't the reason for the rash. Allergic drug reactions like rash have nothing to do with dose. Because of the rash (not because of the double dose) you should check with your doctor before taking more. If your doc isn't available over the weekend, probably someone is covering for her, so call today. ...Read more

I took penicillin but I have an augmentin (amoxicillin and clavulanate) allergy, and now have rash?

I took penicillin but I have an augmentin (amoxicillin and clavulanate) allergy, and now have rash?

Not surprising-: Augmentin (amoxicillin and clavulanate) has two drugs in it- Amoxicillin and clavulanate.

When is a rash in reaction to Augmentin (amoxicillin and clavulanate) more severe than a "side effect? " I have a rash that is very itchy and spreading.

When is a rash in reaction to Augmentin (amoxicillin and clavulanate) more severe than a "side effect? " I have a rash that is very itchy and spreading.

Stop drug, call doc: There is no difference between "side effect" and a severe reaction. Any side effect can be mild or severe. An itchy rash may not seem dangerous, but sometimes can progress and become serious very quickly. Stop the Augmentin (amoxicillin and clavulanate) immediately and contact the doctor who prescribed it. Most likely s/he will switch to a different antibiotic, and you may need to avoid penicillin-related drugs in the future. ...Read more

Hi...I was taking Augmentin for 2 days and developed a rash on my leg and on the head of my penis, the redness on my leg is going away but on my peni?

Reasonable to. ..: To suspect skin reaction (allergy) after taking a drug like Augmentin (amoxicillin and clavulanate) is reasonable but not confirmative. Being not anaphylactic in nature, future repetitive experience may tell. At present, just leave it alone if bearable or just apply steroid-containing skin cream lightly 1-2 times daily and watch for 3-5 days; if not resolving as wished or worsening, seek evaluation and counseling timely. ...Read more

My toddler is on augmentin es 600 for tonsilitis but developed a skin rash. Tomorrow is her last day of treatment. Do I stop treatment now?

Yes or No, but...: Yes or No, meaning it doesn't matter much in real life whether a person take 9 days of Augmentin instead of 10 days, because life is not that exact. The standard is 10 days in the US. More importantly, the doctor wants to hear about the rash or see the rash, to help decide whether or not it was an allergic reaction to Augmentin (it might not be)... to decide whether she is allergic to penicillins. ...Read more

Can augmentin (amoxicillin and clavulanate) cause a non-allergenic rash if pt has virus infection due to viral antibodies?

Call your doctor: Call the doctor who prescribed the antibiotics. Not all rashes are the same. They look different and can be caused by different things depending on if your child has had the antibiotic before and how many doses the child has taken. Rashes in a child may be due to a virus and not antibiotics. Call your doctor. ...Read more

Talk with prescriber: Rash w antibiotic = stop antibiotic &call prescriber ASAP.

Augmentin contains amoxicillin - a rash can occur if URI is mononucleosis (virus). A + strep culture does not necessarily mean strep infection - you can "carry" strep without being "infected."

However, rash can be an allergy to the med.

Bx said spongiotic dermatitis drug reaction likely. EM type rash only on extremities, hands/feet extreme itch and blisters several days after augmentin (amoxicillin and clavulanate). Never had allergy. Why such delayed reaction.?

Need allergy testing: Your body has to have an initial exposure to the drug to develop allergic reaction. This can take time to develop. The symptoms likely started after several doses and then escalated rapidly as your body increased the reaction. Also, this may be more of an adverse reaction to the med. Rather than allergy.

How long does an itchy rash from Amox-Clav typically last after stopping taking the drug?

A few days: Allergic reactions to antibiotics are not common but it may happen. An IgE mediated reaction to a medication may usually present early and with hives and may need interventions such as medications. A late reaction to a medication (a few days later) that is non-IgE mediated will typically go away on its own once medication is stopped, but it may take another 24-72 hrs to resolve. ...Read more

My Daughter has diarrhea, buttocks sores and buttock rash. She's taking amox-clav. I've tried Destin, cortisone & clotrimizole. What can I use?

Amox-clav: Amoxicillin- clavulanate can cause diarrhea and diaper rash. Probiotics such as yoghurt with active cultures can help with the diarrhea.

Desitin can be used layered over the antifungal cream to serve as a barrier to diarrhea. ...Read more
