Do antibiotics affect the birth control pill?

Study after study shows that there are no clinically significant drug interactions* between the vast majority of antibiotics and the birth control pill. Anecdotal evidence from health care providers has led some to recommend using a backup method of birth control for a week after using antibiotics. Long-term use (as for acne) does not increase the risk of pregnancy. There are a few antibiotics, such as rifampin and griseofulvin and some HIV medications, that do interact. The safest approach is to check with your health care provider or pharmacist for advice specific to your situation.

*While some antibiotics may slightly change the absorption of estrogen in the gut, these changes are not enough to change how well the birth control pill works, with the exceptions noted above.

Taken from the newsletter: "Pharmacist's Letter" November 11, 2002

TRUTH:

Women have been warned for decades to use backup contraception when taking oral contraceptives and antibiotics together.

This all started back in the '70s when a few women on oral contraceptives took rifampin and then got pregnant.

Additional anecdotal reports started popping up, suggesting that other antibiotics might be related to unwanted pregnancies in women taking oral contraceptives.

One theory was that antibiotics killed gut bacteria, which are involved in estrogen absorption.

Researchers later discovered that rifampin and griseofulvin actually increase the metabolism of oral contraceptives, making them less effective.

But the evidence for other antibiotics is shaky.

In fact, oral contraceptive levels are not DECREASED by most antibiotics...tetracycline, doxycycline, ampicillin, quinolones, and metronidazole.

Oral contraceptive levels are actually INCREASED by some antibiotics...erythromycin...clarithromycin...and trimethoprim-sulfamethoxazole.

There's growing evidence that most women taking antibiotics with oral contraceptives do NOT have an increased risk of getting pregnant.

But most package inserts still warn that another form of contraception is needed when starting antibiotics.

Explain to women taking oral contraceptives that there can be up to a 3% failure rate, regardless of antibiotic use.

A small number of women might be predisposed to a higher failure rate due to genetic metabolic variations...but it's difficult to determine who these women are.

To be on the safe side, tell women to continue using backup contraception during the entire course of antibiotics and for 7 days after.

Explain that sickness or antibiotic side effects such as diarrhea or vomiting can increase oral contraceptive failure.

Can you take hydrocodone and Ibuprofen together?

Yes, you can. Ibuprofen and Hydrocodone work in different ways. When Hydrocodone is prescribed it is commonly prescribed in combination with acetaminophen (Tylenol), but sometimes prescribed with ibuprofen (Vicoprofen). Hydrocodone is an opioid narcotic that works by blocking opioid pain receptors. Ibuprofen is not a narcotic and works differently to block pain. Many healthcare providers including myself will tell patients to start off by taking ibuprofen (400 mg). If the pain still persists after 30 minutes or so take the hydrocodone. There is no adverse effects and no reason to worry about taking the medicines together as long as you take them in the recommended/prescribed dosages.

Can you get the flu shot while taking Flagyl?

There is no drug interaction problem between the flu vaccine and Flagyl. But whether you get the vaccination while still taking the antibiotic may depend on why you are taking antibiotics. If you have a current infection, it is usually better to wait until that is cleared up before taking vaccines. But, each situation can be different, and this is a question that the doctor who prescribed the antibiotics should be asked to know what is right in your case.

Unless there is a specific reason your doctor wants you to wait, usually the only reason not to get a flu shot while taking antibiotics would be if you have an active infection with a high fever over 101 F. Get your flu shot unless you have a high fever, or the doctor recommends delaying the immunization due to your specific condition.

Will rhus tox interfere with your Coumadin?

Rhus Tox seems to be a homeopathic compound derrived from the plant Rhus toxicodendron-- a plant that I'm pretty sure doesn't exist. The articles call it Poison Ivy, but while that plant is sometimes archaically named as genus Rhus, it's also genus Toxicodendron-- for instance, the Poison Ivy I know and love from hiking is Toxicodendron radicans. T. radicans is rich in urushiol -- a truly nasty irritant toxin related to antigenic response. In other words, dangerous stuff. It's hard for me to believe that Rhus Tox has anything to do with urushiol or T. radicans. The reason I bring all this latin up is that, with so very many homeopathic remedies, it's really hard to know scientifically exactly what you're really getting. Worse, as "herbal" remedies are from live plants, the exact contents vary from season to season and year to year, so you NEVER really know what you're getting, or at what strength. As such, I know of no relationship between urushiol and coumadin, except the itching and toxic effects are pretty awful regardless of drug interactions. As I can't really tell what's in Rhus Tox, there's no way I can say if it's safe or not.

Is morphine sulfate considered a sulfa drug?

No. Sulfa drugs are usually a type of antiobiotics (such as trimethoprim-sulfamethaxazole). The "sulfate" in morphine sulfate just means that the morphine is bound to a salt of sulphuric acid.

antibiotic sulfonamides are different structurally from the non-antibiotic sulfonamides, and appear to be much more likely to result in allergic reactions. Many of the sulfa non-antibiotics, therefore, do not cause problems in people with sulfa antibiotic allergy, although some people who are very sensitive may have a problem, it is unlikely. If you have a problem with dietary sulfites found in many foods, you may have a problem with drugs, such as morphine sulfate.

Some people have a problem with sulfites in foods and drugs, such as morphine sulfate, yet are OK with antibiotic sulfa drugs. It is best to discuss your concerns with your doctor.
