I'm too poor to buy my own prescriptions?
Answer:
"Blessed are the poor" close to you. They get instinctive cure of 95% of their diseases.
I think it'd be cheaper to only buy the penicillin. Penicillin is actually one of the cheapest antibiotics out on the flea market. The 250mg is $4 at Walmart and Target. Several pharmacies may price-match depending on where you live.
Go to WalMart or Target, capture some Amoxicillan believe you can get the generic 500mg, for the $4. Quite an significant antibotic, if you haven't taken it too much in the recent past.
Next time you are prescribed something, tell the doctor that you want a generic. That is a drug explicitly out of patent and individual manufactured competitively by more than one maker, thus lowering prices. Many doctors are suckered into solely prescribing the drugs that drug company representatives recommend, but there are tons older efficient drugs still available.
