    Why contraceptives Fail?

    1. Inconsistency with use of contraceptives: Some contraceptives require uninterrupted administration; and when you don’t take proper observation on your pattern of use for a particular, you can experience failure in therapy. Some expected to be used every day or once in two weeks, once you miss it, you screwed.

    2. Use of other drugs with contraceptives: These drugs are called Enzymes inducers;   they make oestrogen and progesterone quickly absorbed or metabolized in the body, hereby leaving the drug inactive in the body system and making you get pregnant.

    They include:

    a) Antibiotics: used in treatment of skin infection, Urinary tract infection or even typhoid fever interfere with the use of pills.

    Some medications potentially reduce bioavailability of contraceptives in the blood stream, therefore leading to a failure in therapy and pregnancy is detected.

    Examples are: Rifampicin, Penicillin, Amoxicillin

    b) Antiretrovirals: they are a class of medication under antiviral drugs used in treatment of viral infections. Most antivirals are used for specific viral infections but antiretroviral targets HIV/AIDS, some are broad-spectrum antiviral is effective against a lot of viruses. Unlike most antibacterials, all antiviral drugs do not destroy their target pathogen; instead they inhibit or stop their reproduction in the body.

    Examples are;Nevirapine, Efavirenz, lopinavir

    c) Antifungal: they inhibit the growth of fungus and other related species. They are employed in management of diseases called Mycosis which include tinea, yeast vaginal infections, ringworms and others. Oral pills taken with oral antifungal drugs could lead to failure in therapy.

    Examples include; Griseofulvin, Ketoconzole

    d) Anticonvulsants: they are drugs used in the management of seizures and for general management of epilepsy. Examples are; Topiramate Phenorbarbitone Felbamate, Carbamazepine, Oxycarbamazepine, Phenytoinprimidone, Oxycloxacillin

    3. Not taking precaution in use of contraceptives. Contraceptives are diverse in their mode of administration into the body; some are taken orally, injection and implants. Common examples are IUDs, Diaphragm and others. These specialized methods determine their success in preventing pregnancy. It is important to ask question from care givers when you need a contraceptive.

    4. Crohn disease. This condition commonly causes failure in the use of contraceptives especially the oral pills. This condition affects absorption of the pills by the body and hormones responsible in the process of pregnancy and contraception are affected; leading to a failure in therapy.

    5. Time of administration. Using a pill like levonorgesterol (which is expected to on or before 72 hours) after the required time could lead to failure.

    6. Wrong use of Condoms. It must be clear that some condoms get perforated or torn during sex especially when it is doubled. Avoid use of two condoms at once and patronize the best brands of condoms.

    To avoid failure in the use of any contraceptive; read instructions, consult your doctor, pharmacist or a reproductive health nurse.
