There are two types of oral contraceptives: combined hormonal contraceptives (CHCs) and progestin-only pills (POPs). Combination pills contain both estrogen and progestin, while progestin-only pills contain only progestin. Combination pills may be a better choice for some women because they can provide additional benefits, such as lighter periods and reduced acne. Progestin-only pills may be a better option for women who cannot tolerate estrogen or who are breastfeeding.
Combination pills come in various doses of estrogen and progestin. Women who experience side effects, such as nausea or headaches, may be recommended a lower dose pill. Women who have heavy periods may be recommended a higher dose pill.
Oral contraceptives can also be divided into monophasic and multiphasic pills. Monophasic pills have the same dose of hormones in each active pill, while multiphasic pills have varying doses of hormones throughout the cycle. Monophasic pills may be a better option for women who prefer a consistent dose of hormones each day, while multiphasic pills may be recommended for women who experience breakthrough bleeding on monophasic pills.
