Had strep three weeks ago. Amoxicillin for 10days 500mg twice a day. It's back now. What is best treatment this time?

Strep throat: I would be concerned that is wasn't strep throat. given that its back I would go to the doctor to culture the back of your tonsils, then start a different antibiotic. since your a breastfeeding F/U with your OB to be placed on an antibiotic that is safe during breast feeding. Ideally you need something different than a penicillin or amoxicillin. after they obtain cultures you can taper antibiotics. ...Read more

My son doesn't respond well to amoxicillin for ear infections/strep, what would be the best antibiotic for him to take?

My son doesn't respond well to amoxicillin for ear infections/strep, what would be the best antibiotic for him to take?

Hard to say: The strep germ is universally sensitive to any penicillin drug, so any perceived failure to amoxicillin is likely a reinfection or a strep carrier problem. The 1st drug tried for an otitis fails about 10% of the time regardless of drug used. The drug that will work depends on the sensitivity of the germ, that changes with each infection, so there is no perfect choice. Luckily we have several ...Read more

My son is on day 4 of Amoxicillin for strep. Fever is gone but he can hardly swollen without crying in pain. Is it typical?

My son is on day 4 of Amoxicillin for strep. Fever is gone but he can hardly swollen without crying in pain. Is it typical?

Maybe: Strep verified by testing? If so, Amoxicillin is an effective treatment when given in proper amounts. The response varies with the patient and co-factors. Kids can have a throat infection virus and carry strep at the same time. This slows improvement. Time delay before treatment also means there will be a slower response. The lack of fever is a good sign. I'd call your docs office for guidance ...Read more

Day 7 of amoxicillin for Strep got yeast infection. Stopped the amoxicillin. Should I be worried for complications from strep stopping it 3 days early?

Be very worried!: You must take all 10 days of the antibiotic to prevent the risk of rheumatic fever and of developing drug-resistant bacteria. Continue it and treat the yeast infection. Call your doc, to see if a a different antibiotic can be used. Or use otc yeast meds and take amoxicillin with 8 oz of water. ...Read more

I finished a course of amoxicillin for strep throat a few days ago and now my throat hurts again. How likely is it that I have strep again?

Strep throat: Do not know how your strep throat was diagnosed, but this can recur for a variety of reasons. Failure of the first therapy because other bacteria were producing enzymes that destroyed the antibiotic, reinfection, wrong diagnosis, and so on and so on. See a doctor. ...Read more

I currently have the Nexplanon implant in my arm. I was prescribed 500 mg of amoxicillin for strep throat. Will this affect my birth control? How long?

I currently have the Nexplanon implant in my arm. I was prescribed 500 mg of amoxicillin for strep throat. Will this affect my birth control? How long?

Probably no effect: Since the hormones in Nexplanon bypass your gastrointestinal tract and are delivered directly through your arm into your circulation, oral antibiotics like amoxicillin are not likely to affect the contraceptive effectiveness of the subdermal implant. ...Read more

How much amoxicillin 400mg should I give me son that weights 41 pounds and is 6 for strep?

Dose for strep: You can give him roughly 25 mg/kg per dose, twice daily dosing for 10 days. If you have the 400 mg/5 ml suspension of amoxicillin, you could give him 6 ml (=480 mg) twice daily for 10 days. Make sure to give him the full 10 day course even if he is feeling well after a couple of days. ...Read more

My child was prescribed 12.5ml amoxicillin once a day for strep...... should this be at least twice a day?

What's the correct dosage for amoxicillin and how much a day for my 3 1/2 year old. Weighing 37 pounds. She has strep.

Rx'd by physician?: Was the strep throat formally diagnosed by a physician? Strep should be diagnosed by a physician via a rapid test or culture, you don't want to treat with antibiotics for a viral pharyngitis. The physician would have prescribed the amoxicillin in the dosage that is correct. As a general rule, it is 40 mg/kg per day divided into 2-3 doses for a strep infection. Amount depends on concentration. ...Read more

Would 500mg amoxicillin 2x day for 4 days be adequate to rid me of strep?

No, AND...: 500 mg of amoxicillin, twice a day, would need to be taken for 10-14 days to cure a moderate strep throat infection. It might not be sufficient for a severe infection.

If you are considering self-treating a throat infection, I would recommend you see a doctor instead. Some things which look like strep to the naked eye are viral infections, which don't respond to antibiotics at all.

How long are you contagious with strep after you have started taking amoxicillin?

Generally 24 hours: Once on the antibiotic for 24 hours is typically when schools allow students to go back to class, but I would also recommend reducing your exposure to others until the fever is gone and you start to feel better. ...Read more

My son was given amoxicillin 400 mg/ 5 ml for strep. It says to give 20.5 ml 2 times a day. He wEighs 93 lbs is this safe?

Safe=yes, needed=no: This is a dose that I might use to get the meds into the thick muck of a sinus or middle ear infection but it is not needed to treat simple strep.10ml of this preparation 2X/day would be adequate therapy. If the doc saw an ear or sinus infection & didn't tell you, that's a different issue. Any excess med would exit though his kidneys within hours, he might be more likely to have loose stools. ...Read more

My daughter &son weregiven amoxicillin for strep in august, my daughter has become sick again so I gave her this med (exp shows 2014) is this ok?

Bad idea: If it was a liquid med, it begins to deteriorate as soon as water is added and Amoxicillin is no longer good after 2 wks in thr refrigerator or 1 week at room temperature. (no matter what the expiration for the dry powder). If a pill, it would be still in date, but without a proper test proven strep, the treatment may be wrong. If mono, you may be rewarded with an interesting rash. ...Read more

My daughter was on amoxicillin for 3 days prior to being exposed to strep. Is it still possible she can get it even though she's been on her meds?

My daughter was on amoxicillin for 3 days prior to being exposed to strep. Is it still possible she can get it even though she's been on her meds?

Unlikely: Since strep is killed off by amoxicillin, she is not going to get a new strep infection while on it. It will not prevent her from getting a virus that sometimes mimics a strep infection. ...Read more

Prescribed amoxicillin for strep. Rapid test showed very very faint line. Took 1st dose @ 2 pm. Can I take second dose now a@ 11 pm instead of 2 am?

Sounds fine: People who are taking amoxicillin twice a day can take one capsule in the morning, and one in the evening or at bedtime, without being exactly 12 hours apart... but the goal is to be 10-14 hours apart. A person with strep throat usually takes her amoxicillin for 10 days. ...Read more

My 3 year old son is 32pounds and was given amoxicillin 400mg/5ml 100ml to take 5ml twice a day for strep. Take all&finish. Isn't the dosage too much

No, that dose is: Fine. There is a dosing range depending on the child's weight, which is 40-80 mg/kg/day. He is 14.5 kg, so this dose is 55mg/kg/day, which is perfectly fine. ...Read more

Last Saturday daughter was prescribed amoxicillin 400mb/5ml 5ml/twice daily for strep, she weighs 92 lbs, and hasn't bounced back, is dosage correct?

Yes: It takes some time for a kid to come back from any infection. Was the strep verified by test? All strep A is killed by amoxicillin. There is always the possibility a co-infection with mono or other virus can amplify the symptoms and delay response. ...Read more

Tested positive for strep. On day 6 of 10 of amoxicillin, and I got a tattoo today. Am I okay?

Depends: You are okay as far as your sore throat is concerned, but there is question about your thought process. Tattooing is a form of self-mutilation.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex.
Get HPV vaccine ...Read more

I was diagnosed with strep pharyngitis on Tuesday and started Amoxicillin at 2pm. I still can't sleep or function. When should I feel better?

Antibiotic effect: Imagine millions of bacteria where, in a wave of antibiotic, - most of these bacteria explode, with their guts and toxins spilling out all over the place- it's a total mess. This mess attracts thousands of white blood cells, and an inflammatory response ensues that cleans this mess up- resulting in increased tenderness, redness, warmth, and swelling. The area will improve in a few days. ...Read more
