Sperm can live for only a few hours inside the vagina, and even less than that outside the human body, exposed to the open air. If the sperm survive to enter the less hostile environment of the female reproductive tract beyond the cervix, they can survive for up to five days.
Otezla (also known by its non-commercial name, Apremilast) is a systemic medication that received UK Marketing Authorisation (a licence) in 2014. It was approved by the Scottish Medicines Consortium (SMC) for the treatment of moderate to severe psoriasis in Scotland in 2015.
There are several effective topical treatments for psoriasis. While many can be purchased over the counter (OTC), others are available by prescription only. Corticosteroids, or just steroids, are the most frequently used treatment for psoriasis. They are referred to as anti-inflammatory agents, because they reduce the swelling and redness of lesions. Anthralin, synthetic vitamin D3, and vitamin A are also used in prescription topical treatments to control psoriasis lesions. OTC topicals come in many different forms. Two active ingredients, salicylic acid and coal tar, are approved by the FDA for the treatment of psoriasis.
