I have been suffering from acne for a couple years and have been taking bactrim (sulfamethoxazole and trimethoprim) for 4 months. Acne has cleared so can I stop taking the medication?

I have been suffering from acne for a couple years and have been taking bactrim (sulfamethoxazole and trimethoprim) for 4 months. Acne has cleared so can I stop taking the medication?

Yes: You should not take an antibiotic as sole therapy for acne in any case, or any antibiotic for a long time. Your best move would be to stop this and continue whatever topical agent you are using, or topical benzoyl peroxide at least for a while; taper it and see what happens. If you recur, chances are a topical agent will clear you; if not get with your physician.

Accutane vs bactrim (sulfamethoxazole and trimethoprim) acne help!, what to do?

Accutane vs bactrim (sulfamethoxazole and trimethoprim) acne help!, what to do?

First try: "bactrim" isn't as good as some of the other antibiotics, especially the tetracyclines. Don't ever use an antibiotic as sole treatment for acne. Isotretinoin / Accutane is your last resort unless you have cystic acne, for which nothing else will probably work. It's not for the faint-hearted but is a remarkably effective medication.

Is Accutane or bactrim (sulfamethoxazole and trimethoprim) better for acne, what to do?

Is Accutane or bactrim (sulfamethoxazole and trimethoprim) better for acne, what to do?

How bad is it?: Isotretinoin is the strongest and most effective medication for acne and is not for the faint-hearted. Bactrim (sulfamethoxazole and trimethoprim) is an antibiotic and should never be used as sole therapy; a combination of topical benzoyl peroxide plus a course of systemic tetracycline often clears moderately severe acne. If you're female, the oral contraceptive pill if right for you may work; spironolactone's another rx.

How long does it take to start seeing improvement in acne while using bactrim (sulfamethoxazole and trimethoprim) antibiotic?

How long does it take to start seeing improvement in acne while using bactrim (sulfamethoxazole and trimethoprim) antibiotic?

Weeks: Nothing works overnight for acne, except perhaps steroid injections into individual lesions. You might get lucky and see improvement in just a week, but you should be prepared to give it 6 weeks.

Rare: Bactrim (sulfamethoxazole and trimethoprim) is associated with sjs, but it is still a very rare complication. Monitor for rash, and discontinue the medication and talk to your doctor if you develop a rash. Bactrim (sulfamethoxazole and trimethoprim) remains a very safe drug when used appropriately with thoughtful monitoring.

Been taking Bactrim (sulfamethoxazole and trimethoprim) DS for cystic acne for 3 weeks and am still getting new cysts/skin seems worse. Should I rule out Bactrim (sulfamethoxazole and trimethoprim) as ineffective?

Be Patient: Acne is a stubborn condition and is a slow responder to treatment for most people. You will need to give it at least 2 months before you rule Bactrim (sulfamethoxazole and trimethoprim) ineffective. Hang it there. Good Luck

I was told I had MRSA and put on bactrim ds for 10 days, twice a day. After wanting to confirm dx, the dermo did a culture and it showed nothiing! Dermo thinks its just back acne. He told me to finish bactrim then he will start me on doxycycline. Is that

Sounds good: Mrsa is a scary bug but there a great many different strains and many folks harbor them on their skin with no harm. A physician seeing someone with one or more pimples may feel obligated to biopsy for MRSA and treat it as such since it's by far more serious even if it's not really present. It sounds like your dermatologist made the right move.

I was on Minocycline for adult acne and it worked very well for 2 years or so. What's next? I suffer from ulcerative colitis. Is Bactrim (sulfamethoxazole and trimethoprim) an option?

I was on Minocycline for adult acne and it worked very well for 2 years or so. What's next? I suffer from ulcerative colitis. Is Bactrim (sulfamethoxazole and trimethoprim) an option?

Keep exploring: I trust you know not to use an antibiotic as sole therapy for acne, and that you are probably using topical benzoyl peroxide and/or retinoids acid. Meds to consider include spironolactone and the oral contraceptive pill; isotretinoin may make your migraines worse. Your physician is your best guide

I've started taking Bactrim (sulfamethoxazole and trimethoprim) yesterday and developed more acne overnight. Is this common? I'm also using Differin, cereve p.m. and burts bees acne.

I've started taking Bactrim (sulfamethoxazole and trimethoprim) yesterday and developed more acne overnight. Is this common? I'm also using Differin, cereve p.m. and burts bees acne.

How bad is the acne?: Differin is very effective for acne. Burts bees acne is salicylic acid, also good for acne. You can get CeraVe with salicylic acid (SA) and not need Burts bees. Bactrim (sulfamethoxazole and trimethoprim) can help acne but only after 2 or 3 months, usually at a small dose. You will never get worse using it. Acne waxes and wanes with menstrual cycles. Most effective acne therapy for adult women is SPIRONOLACTONE, with or without cert

I have some kind of lung infection. My doctor gave me bactrim (sulfamethoxazole and trimethoprim) 800-160 for 10 days and my symptoms persist. Acne on my back and ache in chest on right?

I have some kind of lung infection. My doctor gave me bactrim (sulfamethoxazole and trimethoprim) 800-160 for 10 days and my symptoms persist. Acne on my back and ache in chest on right?

Reword this question: "Some kind of lung infection" means nothing. Cough? Fever? What is the DR's diagnosis? Any other meds? Ache in chest due to cough? How long ill? Effective therapy of bronchitis is time + inhalers. Antibiotic therapy is not effective for viral infections. While Bactrim (sulfamethoxazole and trimethoprim) is not the first choice for acne, it can be effective. If the acne is improved after 3 months, continue the med. Usually just 1 a d

What's the next best antibiotic class for treating adult acne after doxycycline and bactrim (sulfamethoxazole and trimethoprim)? Is cephalexin or azithromycin a good option?

What's the next best antibiotic class for treating adult acne after doxycycline and bactrim (sulfamethoxazole and trimethoprim)? Is cephalexin or azithromycin a good option?

Acne treatment: Acne is treated by several different medications. Antibiotics aim to treat common skin bacteria that may precipitate acne formation, but antibiotics are not always the cure. Drying agents, washes, benzoil peroxides may be needed. Some severe cases may require dermatology evaluations and tx such as accutane. Best to see the skin dr. (derm) and get tx. Before using many antibx. Best wishes.
