Management of Common Side Effects
SIDE EFFECT |
MANAGEMENT |
Amenorrhea
(absence of vaginal bleeding or spotting) |
Clients using 21-day packs may forget to leave a
pill-free week for menses. If pills are taken continuously, she may not have any periods.
This is not harmful. Check for pregnancy.
If not pregnant and client is taking COCs correctly, reassure.
Explain that absent menses are most likely due to lack of buildup of uterine lining.
If not pregnant, no treatment is required except counseling and
reassurance. If she continues low-dose estrogen COCs (3035 µg EE), amenorrhea
usually will persist. Advise client to return to clinic if amenorrhea continues to be a
concern or switch to a high-dose estrogen (50 µg EE) pill if available and no conditions
requiring precaution exist.
If intrauterine pregnancy is confirmed, counsel client regarding options.
If pregnancy will be continued, stop use and assure her that the small dose of estrogen
and progestin in the COCs will have no harmful effect on the fetus. |
High blood pressure
(> 160/100) |
If BP increases in a client with normal BP who is
using COCs, follow closely. If any warning signs (severe headaches, chest pain, blurred
vision) occur or BP > 160/100, the method should be stopped. If COCs
are stopped, help client choose another (nonestrogen) method. Tell her that high BP due to
COCs usually goes away after 13 months. Take BP monthly to be sure it returns to
normal. If after 3 months it has not, refer for further evaluation. |
| Nausea/Dizziness/ Vomiting |
Check for pregnancy. If pregnant, manage as above. If not,
advise taking pill with evening meal or before bedtime. Reassure that symptoms usually
decrease after first three cycles of use. |
| Vaginal bleeding/ Spotting |
Check for pregnancy or other gynecological conditions.
Advise taking pills at the same time each day. Reassure that spotting/light menstrual
bleeding is common during first 3 months of use and then decreases. If it persists,
provide higher dose estrogen (50 µg EE) pills or help client choose another method. |
Client Instructions
- Take 1 pill each day, preferably at the same time of day.
- Take the first pill on the first to the seventh day (first day is preferred)
after the beginning of your menstrual period.
- Some pill packs have 28 pills. Others have 21 pills. When the 28-day pack is empty, you
should immediately start taking pills from a new pack. When the 21-day pack is empty, wait
1 week (7 days) and then begin taking pills from a new pack.
- If you vomit within 30 minutes of taking a pill, take another pill or use a
backup method if you have sex during the next 7 days.
- If you forget to take 1 pill, take it as soon as you remember, even if it means taking 2
pills in 1 day.
- If you forget to take 2 or more pills, you should take 2 pills every day until you are
back on schedule. Use a backup method (e.g., condoms) or else do not have sex for 7 days.

if you are pregnant.
General Information
- Some nausea, dizziness, mild breast tenderness and headaches as well as spotting or
light bleeding are common during the menstrual cycle (usually disappear within 2 or 3

COCs. For this reason, the client should tell her health care provider if she starts any
new drugs.

is at risk, they should use condoms as well as COCs.
