A study in north London on the use of contraceptives by women with sickle cell disease indicates that the use of combined oral contraceptives is common. Although medical staff usually advised against pregnancy, such advice was almost always ignored. Over half of the women surveyed had some knowledge about antenatal diagnosis. Family planning advice should be an integral part of the care of women with sickle cell disease. In the absence of specific data to the contrary all methods of contraception may be considered, although with appropriate caution.<\/jats:p>","DOI":"10.1136\/bmj.306.6894.1735","type":"journal-article","created":{"date-parts":[[2009,3,30]],"date-time":"2009-03-30T08:16:37Z","timestamp":1238400997000},"page":"1735-1737","source":"Crossref","is-referenced-by-count":47,"title":["Contraceptives, counselling, and pregnancy in women with sickle cell disease."],"prefix":"10.1136","volume":"306","author":[{"given":"R J","family":"Howard","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C","family":"Lillis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S M","family":"Tuck","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1993,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"112","DOI":"10.1111\/j.1471-0528.1983.tb08893.x","article-title":"Pregnancy in sickle cell disease in the UK","volume":"90","author":"Tuck, S.M.; Studd, J.W.W.","year":"1983","unstructured":"Tuck SM, Studd JWW.
