What is the first line treatment for migraine?
Treatment of a migraine attack should be guided by response to previous treatment and the severity of the attacks. A simple analgesic such as aspirin, paracetamol (preferably in a soluble or dispersible form) or a NSAID is often effective; concomitant antiemetic treatment may be required.
Why might simple analgesics not be effective in treating migraine?
Most migraine headaches respond to analgesics such as aspirin or paracetamol but because peristalsis is often reduced during migraine attacks the medication may not be sufficiently well absorbed to be effective; dispersible or effervescent preparations are therefore preferred. Compound preparations containing analgesics and antiemetics are available
Which NSAID is specifically licensed for the treatment of migraine?
tolfenamic acid
Simvastatin and benzafibrate interaction

Why can ACE inhibitors sometimes cause a rapid decline in renal function?
Renal impairment may occur in patients with bilateral renal artery stenosis who have been initiated on an ACEI. Such patients rely on angiotensin II to maintain glomerular capillary pressure via vasoconstriction on the efferent arteriole. This is blocked by the ACEI, lisinopril, causing an abrupt decline in the glomerular filtration rate.
Hyperglycemia is more common with loop or thiazide like diuretics?
Hyperglycemia is a side effect of both but more likely with Thiazide like diuretics

Recent MHRA safety warning concerning mycophenolate mofetil?
Available clinical evidence does not indicate an increased risk of malformations or miscarriage in pregnancies where the father was taking mycophenolate medicines, however mycophenolate mofetil and mycophenolic acid are genotoxic and a risk cannot be fully excluded; for further information, see Conception and contraception and Patient and carer advice. The MHRA advises to exclude pregnancy in females of child-bearing potential before treatment—2 pregnancy tests 8–10 days apart are recommended. Women should use at least 1 method of effective contraception before and during treatment, and for 6 weeks after discontinuation—2 methods of effective contraception are preferred. Male patients or their female partner should use effective contraception during treatment and for 90 days after discontinuation

Can oral EC be used if there has also been UPSI earlier in the cycle?
EC providers can offer a woman UPA-EC or LNG-EC if she has had UPSI earlier in the same cycle as well as within the last 5 days, as evidence suggests that UPA-EC and LNG-EC do not disrupt an existing pregnancy and are not associated with fetal abnormality.
Can oral EC be used more than once in a cycle?
There is evidence that oral EC does not cause abortion or harm to a very early pregnancy. Both
UPA-EC and LNG-EC can therefore be used if a woman has also had UPSI earlier in the same
cycle. Both UPA-EC and LNG-EC can be used more than once in the same cycle if this is indicated
by further UPSI
