Tips in
choosing the best OC formulation . How to select the most appropriate an OCP formulation ??
What to take
into account?? A) It is generally
recommended to use the lowest effective dose.
B) Age of the woman(the contraceptive sekers) :-As women age there are different issues that affect hwer metabolic profile which includes lipid, LFT status.

. Because
of the higher potency of EE , OCs
containing 35 ug EE are similar
to the 50 ug OCs containing menstranol .
New start
Healthy patients
Adolescents : 20 ug EE OCs
, the lowest dose 20 ug EE (except Minesse which contain 15 mcg) in
adolescents may be associated
with BTB ( a lack of bleeding
control )- a leading cause of
discontinuation . In this population
starting with a 25(not available in our country) or 30 ug
EE OC may be associated with
better bleeding control and ultimately better compliance. However the biphasic or monophonic 20 ug OCs
with shortened pill free intervals are associated with improved
bleeding control and may
be a good option to consider. Indicatiosn of OCP in adolescents??
It is prescribed for many non
contraceptive benefits :
I Dysmenorrhea 2) bleeding control
. All OC brands show benefit 25 and 30 ug
OCs may have better bleeding
control than traditional 20 ug
OCs with a 7 day pill free interval.
Reviews have shown that OCs
with levonorgestrel (androgenic progesterone) have good bleeding control.
3) Acne : Choice is nonandrogenic
prog liked desogestrel:-androgenic problems. All OCs brands
show benefit but If
symptoms are severe or continue to be a problem while on an OC switch
OC with formulation containing
a low androgenic progestin desogestrel , ortho Tri Cyclen ( abroad) is approved by the Food
and Drug administration to treat
acne vulgaris.
4) If engaged regularly in illegal/illicit sex(married /unmarried) i/e users
with at risk of STD or HIV
exposure need additional
protection and should use
condoms and OCs .
Take home meassage:-Don’t prescribe low dose formulation which may cause
BTB (an unacceptable side effects for teen agers).:_Early reproductive
first choice : :-Don’t prescribe 20 ,25
ug EE OCPs in young women as these brands may
have increased bleeding problems on 20 ug OCs
with a traditional 7 day pill free interval
a 25 ug EE OC may result in
better bleeding control Use of a levonorgestrel containing pill is associated
with good bleeding
control.
Dysmenorrhea bleeding control
all OC brands show benefit 25 and 30 ug OCs
better than some of the 20 ug OCs
Reviews have shown levonorgestrel containing
OCs to have good bleeding
control
PMS PMDD or fluid retention
all OCs may show benefit. The
progestin DRSP is a derivative of
spironolactone and has some
diuretic effect . Selection of an OC
with DRSP is a good choice for users
with significant complaints of PMS
PMDD or fluid retention.
Acne androgenic problems all
OCs show benefit Consider low
androgenic progestin OCs if severe or if nonresponsive to other
OCs Ortho Tri cyclen is FDA approved
to treat acne vulgaris.
Late reproductive first choice : 20-25 ug EE OCs
Menorrhagia : all OCs show
benefit ?If menorrhagia is a
problem while on an OC switch to OC
with levonorgestrel or one with
lower EE dose. Switching to pill
with higher progestin
to estrogen ratio results in less endometrial stimulation
and may result in less menstrual bleeding
Bleeding problems all Cos show benefit . If midcycle
bleeding and spotting is a
problem while on OC consider switching to an CO with
stronger progestin such as one with levonorgestrel or consider switching
to a higher EE dose OC Estrogen
increases endometrial growth and may improve
bleeding control In some
instances switching to a lower EE done
OC may be effective because
it lowers endometrial stimulation
which results in less
endometrial tissue and less bleeding.
Fibroids or endometriosis all OCs
may show benefit consider a stronger progestin OC
such as one with
levonorgestrel or OC with as low
a dose of EE as
possible.
Significant menstrual
related problems consider
a low dose 21 day extended cycle or continuous OC.
Obesity for heavier women consideration of 30 to 35 ug pill extended use OC or
vaginal ring . Using
more than 35 ug OCs may increase
the risk of venous thrombo
embolisms and a risk benefit
ratio should be considered . As a
user get older risk of thrombosis may
increase and fecundity decreases therefore
using a low EE dose OC may be
considered . Women over 35 with long standing obesity are good candidates for progestin only
methods barriers IUDs or tubal sterilization.
Perimenopausal or women over 35
years old who are healthy
non hypertensive nonsmokers first choice is 20 ug Cos Women in this age group with longstanding obesity hypertension cigarette
smoking known or suspected vascular
disease or diabetes may consider progestin only methods barriers
IUDs or tubal sterilization.
Perimenopausal symptoms
during pill free interval consider
switching to CO with shortended pill
free interval with EE 20 ug /150 ug
DSG for 21 days , 5days
of 10 ug EE and only 2 days hormone free interval or
the new 20 ug OC containing 3 mg DRSP with a 4 day hormone free interval
The amount and potency of either
the particular estrogen or progestin
component in an OC an d the
balance between the particular estrogen
and progestin is associated with hormonal side effects as listed .
Management of these problems generally involves changing
to an OCP with a different
estrogen to progestin balance.
Consider switching to another OC
if current OC is associated with :
Breakthrough bleeding heavy
menses irregular
bothersome or heavy bleeding
that continues after 2 months of use
consider OC with levonorgestrel
or lower EE or progestin ration pill.
Amenorrhea for two cycles after negative pregnancy test switch
to OC with higher EE to progestin ratio
Acne is exacerbated on OC
switch to OC with Norgestimate DSG or DRSP ortho Tri Cyclenis FDA
approved to treat acne vulgaris.
Minor estrogen related
side effects that continue after 2 months switch to OC
with lower EE dose consider
20 ug EE OC .
Nausea or vomiting Switch to
OC with lower EE
Headaches : Stop OCS
immediately if there are
concomitant localizing signs auras
blurred vision weakness or
numbness or if the users is
experiencing a worsening of migratines
Check blood pressure
If blood pressure normal
headaches are simple and there
are none of the symptoms above consider
switching to 20 ug EE OC or progestin only method.
Decreased libido there is a dose dependent suppression of endogenous testosterone production by OCs . Additionally
estrogen dominant pills increase sex hormone
binding globulin that binds up
endogenous androgens switching to OC
with 20 ug EE or to a progestin only
OC may result in more normal free testosterone levels and less negative impact on libido.
Melasma : switch to progestin
only OCP or consider one
with 20 ug EE
Mood swings to 20 to 25 ug OC consider
OC with a different
progestin from current OC
consider DRSP Norgestimate
or DSG consider extended cycle or continuous
OC.
Weight gain : Currently available low dose OCs are generally not associated with
a weight gain consider switching to 20- 25f ug EE OC if fluid
retention is problem use an OC
containing DRSP .
Although OCs are safe in healthy normotensive women
there are important contraindications to their sue and it is
important to identify certain risk factors Additionally OCs are associated with many non contraceptive benefits
and the identification of
conditions that may be improved with OC
use is also important.

Medications
Good data stating that certain drugs
accelerate the biotransformation
of steroids in OCs and concomitant use may make OCs less effective
Rifampin sulfonamides cyclophosphamide barbiturates certain antiepileptics , butazolindin
St John ‘s Wort
Data less convincing for certain
antibiotics fulconazole
Low dose long term antibiotic use for acne appears to be compatible with oc use
Product labeling suggests that
women taing potassium sparing diuretics
angiotensin converting enzyme
inhibitors angiotensin II
receptor antagonists chronic daily use
of nonsteoidal anti
inflammatory drugs should
consult their health care provider
to check if a drospirenone containing
OC is right for them. Under these conditions serum potassium levels should be checked during the first months . Clinical studies
have reported minimal
incidence of problems in women
on these medications who also
take a
DRSP containing OC
Potassium sparing drugs : Women who are ACE inhibitors
potassium sparing diuretics
heparin angiotensin II receptor
inhibitors aldosterone antagonists or
daily NSAIDs should be monitored for potassium before and during
use of DRSP containing OCs. Multiple
studies demonstrate safety of DRSP
containing pills in for
patients on these medications.
