Tutsan tea or grapefruit juice really affects birth control? You know what antibiotics will stop your contraception? All women must know that missing up to 10 pills in a row (7 placebo pills and the 1st 3 pills of a pill pack) does not result in ovulation! You must be aware though, of what you are putting into or onto your body, whether it be teas, juices, throat lozenges, tablets, or even cosmetics.
The main idea to keep in mind is that long term medications that are suspected of inducing liver enzymes to a large extent should be treated as if they may require higher oral contraceptive doses.
Herbs are used in folk and mainstream medicine. Historically and in many cultures, herbs have been and continue to be used as tools for health. On the other hand there are herbs and supplements which ,because of this power, deserve both respect and caution.
Alfalfa (Medicago sativa)
Black and Blue Cohosh
St. John’s Wort
Herbal Dietary Supplements: As with most other drug interactions with OCPs it is unlikely that diet pills would decrease the effectiveness of birth control pills but this is just an educated guess.
Drugs: There are two ways that antibiotics potentially can reduce the action of birth control pills. Birth control pills contain estrogens. Some antibiotics, e.g., rifampin, griseofulvin, cause the enzymes in the liver to increase the break-down of estrogens and thereby can decrease the levels of estrogens in the body and the effectiveness of the pills.he other way that antibiotics could interfere with the effectiveness of birth control pills is by reducing the re-circulation of estrogens within the body. Estrogens, e.g., ethinyl estradiol, in birth control pills are broken-down by conversion in the liver to other chemicals which are then secreted into the intestines in the bile that is produced by the liver. Bacteria in the intestine are able to convert these chemicals back into the active estrogen which is then reabsorbed into the body. This re-circulation is called entero-hepatic cycling. Theoretically, antibiotics can kill the bacteria that convert the inactive chemicals to the active estrogen, and, therefore, may interfere with the effectiveness of birth control pills. Unwanted pregnancies could occur.
Anti-tuberculosis drugs such as rifampin anti-fungal drugs such as griesofulvin and antibiotics such as tetracycline and ampicillin were the most strongly suspected for drug interactions causing an increased pregnancy rate.here’s the list of drugs that decrease pill effectiveness by increasing liver hormone breakdown:
Phenobarbital, Phenytoin (Dilantin),
St. John’s Wort,
Lamotrigine (Lamictal)* -Lamictal is, itself affected by pills and pills affect Lamictal
xenedrine (weight-loss pills)
Barbiturate (in general)
