Ngày nay, việc sử dụng thuốc tránh thai khẩn cấp ngày càng phổ biến. tuy nhiên nhiều người không dùng nó đúng cách thậm chí có thể dẫn đến những hậu quả nghiêm trọng.

Và đúng theo tên gọi: Thuốc tránh thai khẩn cấp chỉ được dùng trong những trường hợp “khẩn cấp” khi quan hệ mà không có những biện pháp bảo vệ hoặc bảo vệ không thành công. Việc lạm dụng nó lâu ngày sẽ dẫn đến những ảnh hưởng lên chính sức khỏe sinh sản của các bạn gái.

Vậy nên dùng ra sao?

Thuốc tránh thai khẩn cấp cũng tương tự như thuốc viên tránh thai hàng ngày, nó có chứa hoóc-môn nữ progestin hormone. Tuy nhiên, hàm lượng kích thích tố progestin trong thuốc tránh thai khẩn cấp cao hơn nên ngay lập tức nó có tác dụng ngăn cản sự rụng trứng, tránh dẫn tới thụ thai.

Hiện nay trên thị trường lưu hành các nhóm thuốc trán thai khẩn cấp  như: thuốc đơn thuần, thuốc kết hợp giữa estrogen và progestafit, thuốc mifepriston.

Có 2 loại thuốc tránh thai khẩn cấp:

-          Loại 2 viên gồm : levonorgestrel 0,75mg dạng viên uống. Uống 1 viên càng sớm càng tốt sau giao hợp không được bảo vệ từ 2-6 giờ đầu., bắt đầu không quá 72 giờ. Uống viên thứ 2 cách 12 giờ sau, thì tỷ lệ tránh thai 83%.

-         Loại 1 viên có chứa Levonorgestrel 1,5mg uống một lần. Nên dùng trong vòng 72h đầu.

Theo khuyến cáo không nên dùng thuốc tránh thai khẩn cấp quá 2 liều/ 1 tháng.

Các tác dụng phụ thường gặp:

-         Buồn nôn: là tác dụng phụ thường gặp nhất. Tốt nhất sau khi dùng thuốc nên nghỉ ngơi, ăn thức ăn mềm , dễ tiêu. Có thể dùng các loại thuốc chống buồn nôn

-         Đau đầu: Nếu đau nhẹ có thể dùng các thuốc giảm đau thông thường. Nếu có tình trạng đau nặng, và tăng lên tốt nhất nên đến cơ sở y tế khám chuyên khoa về thần kinh khi nghi ngờ có những bệnh lý về thần kinh.

-         Cảm giác căng tức ngực, ra nhiều khí hư do hàm lượng estrogen tăng cao.

-         Kinh nguyệt thất thường hoặc rong kinh. Trong trường hợp, chậm kinh kéo dài, bạn nên đi khám hoặc dùng que thử để loại bỏ khả năng có thai.

-         Ra máu giữa chu kì kinh

-         Đau dạ dày

-         Choáng sau dùng thuốc.

 

Việc sử dụng thuốc tránh thai khẩn cấp không phải biện pháp an toàn mà bạn nên áp dụng vì tác dụng tránh thai của phương pháp này không cao bằng phương pháp dùng thuốc hàng ngày hay các phương pháp khác.

Việc dùng thuốc tránh thai khẩn cấp đôi khi gây ra nhiều tác dụng phụ và thậm chí vẫn có những trường hợp có thai sau khi dùng thuốc.

Nếu dùng hãy cân nhắc và đảm bảo bạn chỉ dùng vào những trường hợp “khẩn cấp”. Mỗi tháng không dùng quá 2 liều thuốc .
