I really don't know of any over the counter muscle relaxants...I would give a call to your pharmacist and see if they can recommend anything...plus, if you have one of file from a previous Rx they may be willing to contact your doctor to see if you can get it filled early. You could also do an herbal search on muscle relaxants but again consult your pharmacist if you are taking any other drugs.
the only actual OTC type of muscle relaxer that i know of is magnesium.it is natures little muscle relaxer.if you try taking it orally or even soaking in a hot tub with a cup of epsom salts(pure magnesium granules)this could help some with the spasms.i HAVE TO do this soak every night before bed or my leg spasticity gets horrid while i try to sleep.and this is from an actual spinal cord injury.if this works on my spasticity,it should at least make a dent in yours.the mag actually gets absorbed thru the skin and directly into the muscles themselves so it does really help me alot.just a suggestion that could help some til you see your doc.its about the only 'natural" thing that i have found that really does work for me.good luck,Marcia

There is an over the counter med called Percogesic. My pharmacist told me that it has a mild muscle relaxer in it. I buy it at Rite Aid. It does help my pelvic cramps sometimes, and really helps headaches when other things don't.
